Answer:
to reproduce sexual is better
Explanation:
i think if your asexual you don't feel attraction so you probably wont have intercourse and not reproduce whereas if your sexual you will
Answer:
tough question
Explanation: asexual is a broad broad broad spectrum some people who are ace are willing to have intercourse just wont find pleasure in it or some people are willing to have intercourse every once in a while or when they feel like it so technically ace people can reproduce just probably more likely that they wont but the question is also probably not the best because not all ace people are the same
What energy transformations are going on within the skateboarder’s body during this process?
Answer:
When they slide down, they lose this potential energy, which turns into kinetic energy and thermal energy. Thermal Energy - This energy is related to the temperature of a body or a system. When friction is involved in a system, part of the kinetic energy is transformed into thermal energy.
Jeremiah is on a school trip to a forest preserve. According to the urban heat island effect, as Jeremiah leaves the city and heads toward the nature preserve, the temperature should (first drop-down) . That's because large cities (second drop-down) more heat than rural areas. When Jeremiah arrives at the preserve, he immediately notices the effects of solar radiation. The blacktop in the parking lot feels (third drop-down) the green grass where his class will eat their picnic lunch. →First drop -down options 1. Remain the same 2. decrease 3. increase Second drop-down options 1. absorb 2. transmit 3. reflect third drop-down options 1. hotter than 2. cooler than 3. same temperature as←
Answer:
2. decrease
3. reflect
1. hotter than
Explanation:
As Jeremiah will move towards nature preserve the temperature will decrease because heat once absorbed as energy is reflected by a temperature rise and large cities reflect more heat than rural areas. It is so because large cities have buildings and other structures that absorb fore heat and reflect more heat.
The blacktop will be hotter than the green grass because blacktop reflects more heat in comparison to green grass.
Hence, the correct answer is:
2. decrease
3. reflect
1. hotter than
Answer:
decrease
reflect

1. The wings are missing in mutant fly L, which is likely the result of a mutation in________ .
2. Mutant fly X has lost the head and thorax. The gene most likely responsible for this mutation is____________.
3. Thoracic and abdominal structures are missing in mutant fly Q. The gene most likely responsible for this mutation is__________ .
4. Mutant fly F has predominantly lost abdominal structures, which is likely the result of a mutation in _________ .
5. The mutation observed in mutant fly O resulted in defects within the anterior or posterior regions of each segment. The gene that most likely caused this mutation is _________.
6. Segment-sized sections of every other segment are missing in mutant fly Z. One likely candidate gene is ________
a. hunchback (a gap gene)
b. even-skipped (a pair-rule gene)
c. wingless (a segment-polarity gene)
d. knirps (a gap gene)
e. hedgehog (a segment-polarity gene)
f. Kruppel (a gap gene)
Answer:
1.wingless (a segment-polarity gene)
2. hunchback (a gap gene)
3. Kruppel (a gap gene)
4. knirps (a gap gene)
5. hedgehog (a segment-polarity gene)
6. even-skipped (a pair-rule gene)
Explanation:
The gap genes are genes expressed during embryonic development of some arthropods. Loss of function mutations of the gap genes are responsible to produce structural "gaps" in the corresponding region of the embryo. The gap genes are transcription factors that modulate the expression of pair-rule genes, which in turn are required for embryonic development of the alternate segments. On the other hand, the segment polarity genes are involved in determining the anterior/posterior axis of each segment (the segment polarity network). In the embryo, segment-polarity genes are expressed at specific localizations only after the expression of gap and pair-rule genes.
HELPPPPP Which of the following pieces of evidence supports that species change due to certain genetic variations? Darwin's theory of evolution was incorrect, as it did not account for variation in a species. Natural selection causes variation but cannot cause the evolution of a new species. Mutation and natural selection both cause changes in a population. Changes in a population abruptly occur as a direct response to the environment.

C. If you combined the elements in the product of this reaction, what type of
reaction would it be? Hint: What is the reverse of the equation you just
balanced? (1 point)
Answer:
Reversible reaction
Explanation:
If the elements of the product combine together in a chemical reaction, this reaction is called reversible reaction because the reaction moves in backward or reverse direction. For example, if acid i. e. HCl combine with base i. e. NaOH which are the reactants, it produces two products salt (NaCl) and water (H2O). If salt (NaCl) and water (H2O) combine again with each other, it produces acid i. e. HCl and base i. e. NaOH, such type of reaction is called reversible reaction.
Consider a material for a vascular graft application with proteins adsorbed to its surface and a second material with proteins covalently attached to its surface. For which material would you expect the protein layer to be more stable under flow conditions similar to those found in a blood vessel? Why?
Answer is given below :
Explanation:
Individual-specific proteins are placed on the graft material so that the body does not recognize the graft as a foreign substance and treats it as a part of the body’s natural tissue structure. If the body recognizes the graft as a foreign substance, it produces an immune response against it and leads to a graft rejection reaction by the body. In order for these proteins to attach to grafts, a covalent bond for absorption must be preferred. Absorption is a reversible process and, if used, can lead to de-absorption of bound proteins, including blood, after dissolving by turbulence and pulling to the grafting material by blood flow (velocity up to 40 cm/sec). The remaining infectious tissue is detected foreignly, activating the immune response. On the other hand, covalent bonding is irreversible in nature and vascular flow does not have a disruptive effect on the bond between the graft and the protein, reducing the stable state of the graft and the possibility of rejection.What cell feature is used by scientists to classify an unknown cell as prokaryotic or eukaryotic?
Answer:
Like a prokaryotic cell, a eukaryotic cell has a plasma membrane, cytoplasm, and ribosomes, but a eukaryotic cell is typically larger than a prokaryotic cell, has a true nucleus (meaning its DNA is surrounded by a membrane), and has other membrane-bound organelles that allow for compartmentalization of functions.

How does the movement of particles of matter change when temperature increases?
Decreases
Increases
Increases then decreases
Does not change
Answer:
Increases
Explanation:
The movement of particles of the matter increases with the increase in temperature.
The particles gain kinetic energy with increasing temperature and move in faster rate.
For example: When we blow a balloon with our mouth, we increases the temperature inside the balloon, the particles in the balloon gain kinetic energy that leads to the faster movement of gas particles in the balloon and they collide with each other and surface of balloon, after a peak the balloon get burst because of high kinetic energy and high collision.
Hence, the correct answer is "increases".

a. Autosomal dominant
b. Autosomal recessive
c. X-linked dominant
d. X-linked recessive
e. Mitochondrial
Answer:
e. Mitochondrial
Explanation:
This is a case of mitochondrial heredity so correct answer is e. Mitochondrial In this case, the mother transfers her mitochondria to her children. So the child is affected. The male does not pass this trait on to his children. We can see from the lineage that the mother has defective mitochondria so all their children will have defective mitochondria. One of his sons has mitochondrial, but is unable to pass it on to the next generation.ASAP Why is ATP used as an active energy source over glucose? A. It is more abundant in food sources. B. It releases its energy quickly in a single reaction. C. It releases its energy slowly through multiple reactions, allowing it to last longer. D. It has more energy.
Answer:
B.
Explanation:
Glucose is an organic molecule that stores ATP or energy while Adenosine triphosphate (ATP) is an energy-carrying molecule.
ATP used as an active energy source over glucose because ATP is a shorter process and releases energy in a single reaction as glucose first converted into ATP and then used as energy in cellular respiration.
Hence, the correct option is "B".

A researcher discovers that polar bears have very good insulation and very think hair (similar to pandas). However, they do not show the rest of the panda behaviors. For example, they have high daily energy expenditure and are very active. Why are the panda and polar bear so different
Answer:
Panda and polar bear have some similar characteristics but they also have differences in their behaviors such as polar bears have high daily energy expenditure and are very active while pandas are not.
The panda and polar bear so different because of the geographical difference where they live.
Polar bears are marine mammals and live in north pole perform swimming in north oceans and also move on ice flows, where they catch seals for survival, it makes them active and energetic.
While Pandas are found in China bamboo forests and are herbivores. They eat leaves from bamboo trees, for which they do not require to be more active and get their food easily. So, Pandas are not active as polar bears.
As the climate of North pole and China is cold, both polar bear and panda have very good insulation

A purebred tall pea plant is cross-pollinated with a tall, heterozygous pea plant. Use a Punnett square to determine the probability the offspring inherita
recessive short allele. (I point)
75%
25%
0%
50%
Answer:
0%
Explanation:
This question involves a gene coding for height in pea plants. The allele for tallness (T) is dominant over the allele for shortness (t). This means that allele T will be expressed over allele t in an heterozygous state.
A purebred tall plant will possess genotype: TT while a heterozygous tall plant will possess genotype: Tt. The two parents will produce the following gametes:
TT- T and T
Tt- T and t
Using these gametes in a punnet square (see attached image), the following offsprings with genotypes: TT and Tt in a ratio 1:1 will be produced.
TT offsprings are purebreed tall while Tt offsprings are heterozygous tall. Hence, based on the question, no offsprings of this cross will possess the recessive genotype (tt). This means that 0% of the offsprings of this cross will be short.

Scientists today are studying tidal power as an alternative energy source for generating electricity. Some scientists conclude that tidal power is a good alternative source of energy because it uses a natural process, does not rely on fossil fuels, and does not release greenhouse gases. These scientists recommend building tidal power plants around the United States in locations with high tidal power potential. Other scientists conclude that tidal power is not a good alternative energy source because tidal power plants can negatively impact the surrounding ecosystem by killing marine animals, restricting fish migration, reducing the natural flow of water, and causing silt buildup in waterways. These scientists recommend not building tidal power plants in U.S. waterways. Both conclusions are based on valid data and scientific reasoning. How can both conclusions be valid?
Answer:
See the answer below
Explanation:
Both conclusions can be valid because they are based on valid data and scientific reasoning.
In order for a data to be valid in making a conclusion, such data must have been collected through a scientific experiment that is devoid of subjectivism. In order words, the data must have been objectively collected via standard experimental procedures.
Once data have been collected, they are analyzed and used to make valid conclusions based on the hypothesis which must have been made earlier before the experiment.
Conclusions made from standard experimental procedures and scientific reasonings are valid and such experiments are reproducible.
Hence, as long as the data from which the conclusions were made can be reproduced through the same experiments, the conclusions are valid.

How are red blood cells able to move through narrow vessels to carry oxygen throughout a multicellular organism? (1 point) a)They are flexible because they lack a plasma membrane. b)They are small because they lack a nucleus. c)They are long and thin with a tail-like end. d)They are small because their organelles are smaller than those of other cells.
Answer:
The correct answer is - option B. They are small because they lack a nucleus.
Explanation:
Red blood cells or erythrocytes are specialized cell that produce in bone marrow and have specific role such as carrying oxygen from lungs to deliver it to the various organs and carry out carbon dioxide.
In mammals these cells lack cell organelles such as nucleus and mitochondria, a major factor that determined its smaller size. The size of RBC are move through narrow vessels throughout a organism because of its specific size and shape that provide it space for hemoglobin and allow to be flexible and bend to move through narrow vessels.
Thus, the correct answer is : option B. They are small because they lack a nucleus.

5.Do the differentiated teeth of the dolphin have specialized functions like our teeth and most other mammals
Answer and Explanation:
Dolphins are homodont. This means that all their teeth are all equal. They do not differentiate between each other as the human´s teeth or other mammal´s teeth.
Dolphins have different feeding strategies according to the species. They might be suction feeders, or they might catch their prey using the jow and mandible occlusion strenth.
Dolphins that catch their prey by using their jow and mandible do not chew, so they use teeth mostly to catch their prey and manipulate them before swallowing them. This is why they do not need differentiated teeth. Because they just use them to catch and manipulate.
Those dolphin species that are suction feeders do not need teeth to catch their prey because they just suck them. Most of these species only have a few teeth, mostly in their jows. These teeth are used for fighting with other individuals. Inter- and intra-specific fights among animals of the same gender and age are very common. It is believed that as these species do not need teeth for catching their prey, they evolved loosing most of them but those needed during confrontations. This is the case of Grampus griseus, Risso´s Dolphin, that only have 5 to 7 teeth in their jows.
Choose a strategy to clone genes known only by a mutant phenotype in organisms with highly efficient transformation procedures and relatively small genomes.
Answer:
By combining traditional genetic mapping with whole-genome sequencing (next-generation sequencing)
Explanation:
Map-based cloning, also named positional cloning, is a technique used to identify genetic sequences linked to markers whose exact physical localization in the genome is known. Map-based cloning has shown to be useful to clone genes, however, this approach is limited to the existence of mutant phenotypes in different organisms/accessions/strains. In recent years, map-based cloning has been combined with next-generation sequencing methodologies in order to clone genes in background of single mutants without information on multiple organisms. This type of strategy has the potential for identifying causal mutations and thus clone genes in species with small genomes and high transformation efficiencies such as, for example, Arabidopsis thaliana.
