Answers

Answer 1

Answer:

1. Receptor (nociceptor).

2. Afferent neurons.

3. Spinal cord.

4. Motor neurons.

5. Efferent neuron (effector).

Explanation:

In Biology, stimulus can be defined as an obvious change in either the chemical or physical structure of an organism' environment (either external or internal). Thus, all living organisms (both animals and plants) respond to changes in their environment and consequently, an appropriate response or reaction is made. Also, stimulus arising from within the organism is known as internal stimulus while those from its environment are known as the external stimulus.

In organisms, the specialized cells that detect stimulus are generally known as sensory receptors while a group of these receptors is referred to as sense organ.

In this scenario, you accidentally stub your toe on a chair when walking in a darkened room. A receptor (nociceptor) relays this information by sensory nerves in the afferent neurons to the spinal cord, which in this case is the spinal cord. You immediately step back because the spinal cord sends a command via the motor neurons to your leg muscles, which are acting as the efferent neuron (effector).

unlike eukaryotes prokaryotes do not contain a system of internal membranes. Any organelles, proteins, and genetic material are free - floating within the cytosol. Select the description below that correctly identifies how protein synthesis differs in prokaryotic and eukaryotic cells as a result of eukaryotic compartmentalization.

A. RNA processing occurs outside of the nuclear membrane in prokaryotes and inside it in eukaryotes.

B. Translation can occur before transcription in a prokaryote but not in a eukaryote.

C. Transcription and translation can occur simultaneously in a prokaryote but not in a eukaryote.

D. Ribosomes are needed for translation of mRNA in eukaryotes, but they are not needed in prokaryotes.

Answers

Answer:

The difference in protein synthesis in prokaryotic and eukaryotic cells, due to the compartmentalization of the latter, is that transcription and translation can occur simultaneously in a prokaryote but not in a eukaryote (option C).

Explanation:

Eukaryotic cells are characterized by a true nucleus, surrounded by a nuclear membrane. Since transcription occurs in the nucleus and translation for protein synthesis occurs in the cytoplasm, the former process occurs before the latter.

In prokaryotic cells the absence of a nucleus and compartmentalization system makes it possible for transcription of DNA into RNA and translation to occur simultaneously.

The other options are not correct because:

    A. RNA processing, in both prokaryotes and eukaryotes, occurs in the cytoplasm.

    B. Transcription precedes translation in all organisms.

    D. Ribosomes are present and are necessary for protein synthesis in both prokaryotes and eukaryotes.

A punch is painful, while a hug is not, because a punch produces _______ action potentials from each sensory neuron. A) stronger B) more frequent C) faster-moving D) fewer

Answers

Answer:

B) more frequent

Explanation:

This occurs because a punch produces more frequent action potentials from each sensory neuron. This is only caused when there are rapid and sudden changes. A punch is fast and causes very sudden changes when the punch comes into contact with the human body. This therefore, causes these fast and sudden changes which fire very frequently from each sensory neuron. A hug is soft and does not affect the human body in such a sudden way so it does not cause frequent action potentials.

Easy: G1 stage, G2 stage, S phase, prophase, metaphase, anaphase, telophase and lastly cytokinesis

The cell cycle in the correct order is G1, S, G2, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis.

What is the cell cycle?

Prophase, metaphase, anaphase, and telophase are the four phases that a cell goes through. To form chromosomes, chromatin condenses (sister chromatids joined at the centromere).

In prophase, the chromosomes get shorter and thicker, in the center of the cell, during the metaphase, the chromosomes align. Chromatids separate during the anaphase process and travel to the opposing poles.

Telophase: Two nuclei are produced when nuclear envelopes have reformed around each chromosomal group.

Therefore, the cell spends the majority of its time in interphase, which is also when it grows, duplicates its chromosomes, and gets ready to divide.

d. Genotype YyRr, if dominant Y and R are on the same chromosome, 50% crossing over

Answers

Answer:

The correct answer would be -

1- YR, Yr, yR and yr.

2. Yr, yR

3. YR, yr

4. YR, Yr, yR & yr

Explanation:

A mature male or female haploid germ cell that fuses with another gamete of the opposite sex during the process of fertilization to make a zygote in sexual reproduction.

The law of Independent Assortment presented by Mendel says that alleles for different traits are passed and assort independently of one another in the gametes.

1. If Y and R on different chromosomes then they will produce four gametes and assort independently - YR, Yr, yR & yr.

2) If Y and R on the same chromosomes and no crossing over occurs then they will produce only two gametes as Y and R will not come together - Yr & yR.

3).  if dominant Y and recessive r are on the same chromosome, no crossing over then only two gametes will form as Y and r will not assort together - YR & yr.

4). if dominant Y and R are on the same chromosome, 50% crossing over produces 4 types of gametes, YR, Yr, yR & yr.

3. What happens during each of the four phases
of mitosis? Write one or two sentences for

Answers

Answer:

After DNA replicates and the cell is about to divide, the DNA condenses and coils into the X-shaped form of a chromosome. During this process, sister chromatids separate from each other and move to opposite poles of the cell. This happens in four phases, called prophase, metaphase, anaphase, and telophase.

Mitosis is a process of division in which a parent cell is divided to form two identical daughter cells.

Mitosis completes into 4 steps:

Prophasemetaphaseanaphasetelophase.

What is the process of mitosis?

The process of mitosis division completes into four stages:

Prophase – The chromosome is condensed and compact. The spindle fiber forms.

Metaphase – The nuclear membrane dissolve, and the spindle fiber aligns all the sister chromatids (chromosome) in one line.

Anaphase – The sister chromatids separated from each other and centromere. The spindle takes each strand to the opposite pole.

Telophase – the nuclear membrane appears again around each set of the chromosome. The chromosome uncoil and the cytoplasm divide into two cells, and this process is called cytokinesis.

Thus, this is the process of mitosis.

Answers

Answer:

Transcription into mRNA strand will produce: ACU CAG CUG ACC GAC UGG CAU CUG

Translation into amino acid sequence will yield: Threonine- Glutamine- Leucine- Threonine- Aspartic acid- Tryptophan- Histidine- Leucine

Explanation:

- Transcription is the process by which DNA template is used to synthesize a mRNA molecule in the nucleus (eukaryotes). The transcription, which is carried out by an enzyme called RNA polymerase, follows the complementary base pairing rule i.e. A-T, G-C. Note that Uracil replaces Thymine in the RNA molecule.

Based on this question in which a DNA strand was given as follows: TGA GTC GAC TGG CTG ACC GTA GAC

The mRNA strand that will result from transcribing this DNA will be: ACU CAG CUG ACC GAC UGG CAU CUG

- Translation is the process by which mRNA strand is used to synthesize amino acid sequence (protein) in the ribosomes. In the mRNA sequence, nucleotides are read in a group of three called CODONS. Each codon specifies an amino acid. Based on the mRNA sequence as follows: ACU CAG CUG ACC GAC UGG CAU CUG, the amino acid sequence that will result after using the genetic code will be: Threonine (Thr)- Glutamine (Gln)- Leucine (Leu)- Threonine (Thr)- Aspartic acid (Asp)- Tryptophan (Try)- Histidine (His)- Leucine (Leu).

Myopia is a phenotype that results from interactions between genetic factors and the environment

Explanation:

A quantitative trait is a polygenic trait that depends on the cumulative effects of many genes and the environment. Some examples of quantitative traits include weight and height. Myopia is a quantitative trait whose phenotype depends on the combined action of different genes and the environment. It has been shown that genetics plays a central role in this trait (myopia), it is for that reason that myopic parents are more likely to have myopic children. However, there also are environmental factors (e.g., diet) which increase the risk to suffer myopia.

a) Accurate, but not precise
b) Precise, but not accurate
c) Accurate and precise
d) Neither accurate or precise

Answers

Answer:

d) Neither accurate or precise

Explanation:

Accuracy and precision are critical factors in the experimental procedure. Accuracy can be defined as the amount of uncertainty in the process of measurement in relation to the true value (in this case, 10 mL). On the other hand, precision is an independent feature of the accuracy which indicates the repeatability of the measurement process (in this case, three measures weren't repeated). Therefore, precision indicates the confidence of a particular measurement, while accuracy indicates how close is this value to the real value.

Describe the movement of oxygen molecules if there were more oxygen molecules
outside the cell

Answers

Explanation:

Because there's a higher concentration of oxygen molecules outside the cell compared to the cell's cytoplasm, you'll see that oxygen diffuses into the cell along this concentration gradient. ... Because the molecules are moving at random, some will move out of the cell, but most will be moving in in this case.

Transporation is the mechanism by which the molecules and enzymes move in and out of the cell. When more oxygen is present outside the cell diffusion will occur along the concentration gradient.

What is diffusion?

Diffusion is a transportation mechanism that involves the movement of the ions and the molecules from the high concentration area towards the low concentration region.

The high amount of oxygen present outside the cell will diffuse through the cell membrane inside the cell along the concentration gradient so that the concentration inside and the outside achieves equilibrium.

Therefore, the movement of the oxygen molecules from high concentration to low is diffusion.

Explanation:

The mutation would be most harmful to the cells if it resulted in the deletion or insertion of nucleotide from or in any coding sequence of the DNA.

Deletion or insertion of a nucleotide from/into the coding sequence of DNA results in a frameshift mutation away from the original protein. Deletion/insertion of a nucleotide from/to the coding sequence of a DNA can cause a totally different protein to be synthesized from such DNA or, worse still, results in a nonfunctional protein.

Wolves that live in snowy climates often prey on rabbits. Some rabbits can move quickly across deep snow because they have large feet that don’t sink into the snow. Rabbits without this adaptation move more slowly across the snow. Which statement best justifies how the rabbit population changes over time?
A. Sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment.

B. The ocean water would change its current so that the acidic water is relocated to another area and allow sea coral to survive.

C. The ocean water would change its composition to reduce the amount of carbon dioxide contained and allow sea coral to survive.

D. Sea coral would become extinct because of its inability to make adaptations fast enough to adjust to the changes in the environment

Answers

Answer:

It's A

Explanation:

Just like the corals have genetic mutations to adapt to their environment so do the rabbits change their genetic characteristics to make sure the species continue it's lineage by evolving and growing their feet so they can be faster and not sink in the snow, becoming harder preys to catch, otherwise, if their paws were smaller, they would be slower and, therefor, an easy catch for the wolves, probably becoming extinct after awhile.

The statement that justifies how the rabbit population changes over time is sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment. So, the correct option is A.

What is Adaptation?

Adaptation is the process by which a species becomes fitted to its environment; it is the result of natural selection's acting upon heritable changes.

Rabbits have to change their genetic characteristics same as the coral have genetic mutations to adapt to their environment and to make sure the species continue its downstream by evolving and growing their feet, so they can run faster in the snow and successfully escape from predators. If rabbits are not evolved with an environment that does not favor them, they are surely eliminated from nature.

Therefore, the statement that justifies how the rabbit population changes over time are sea coral would make immediate adaptations through genetic mutations to adjust to the changes in the environment.
