A characteristic that an organism can pass on to its offspring through it’s genes
Answer:
hair color or eye color
Explanation:
dont know how to explain
Answer:
A trait. unless you're looking for specific traits then look at the other person's answer.
Explanation:
A trait is a characteristic passed on the the offspring
This Pedigree represents a family with an Autosomal Recessive Disorder. What is the probability that IV4 and IV5 have a child with the trait?
As this family has an Autosomal Recessive Disorder, we must know that this disorder will only be expressed, in the family members who are homozygous recessive (aa), in this way, to know the probability of IV-4 and IV-5 to present the disorder, we must evaluate the probabilities of combinations of their parents' alleles in a diagram called a punnett square.
In the pedigree above, we can see that the dark colored balls and squares represent the members of the family who have the disorder and therefore have the "aa" genotype.
Thus, when observing the crossings throughout the family, we know that the father of IV-4, has the genotype "Aa", however we do not know which genotype of the mother of IV-4, but as she does not have the disorder, she may have the genotype "Aa", or "AA", for that reason, we must make the punnett square for both situations and see what the probabilities of IV-4 will present the disorder.
As you can see in the figure attached below, if IV-4's mother has the "Aa" genotype, IV-4 will have a 25% chance of presenting the disorder. If IV-4's mother has the "AA" genotype, IV-4 has a 0% chance of inheriting the disorder.
In the case of IV-5, we can see that his mother has the disorder and therefore has the genotype "aa", we know that his father does not have the disorder, but we do not know if the father's genotype is "AA" or "Aa "and therefore we must evaluate both situations.
As you can see in the figure below called "IV-5", if IV-5's father has the "AA" genotype, IV-5 will have a 0% chance of inheriting the disorder. However, if IV-5's father has the "aa" genotype, IV-5 will have a 50% chance of inheriting the disorder.

Explanation:
which of the following words best matches this definition: The process in which the best adapted organisms survive and pass on their traits, while those that are NOT well adapted do not survive.
Answer:
Survival of the fittest
Explanation:
According to the Darwin’s theory of survival, a species can survive among its peers only when it is fit enough to adapt to the natural changes and hence remain alive till its reproductive stage in order to produce fertile offspring.
Such species which survive are known as fit species while the remaining unable to cope with changing environment die out at an early stage of life.

DQ19: A pea plant must have exactly one of each of the following pairs of traits: Short (s) or tall (t); round (r) or wrinkled (w) seeds; yellow (y) or green (g) peas; and white (wh) or purple (p) flowers. For example, a pea plant can be short with wrinkled seeds, green peas and white flowers. How many different classifications of pea plants are possible
Answer:
There are 16 possible different classifications of pea plants.
Explanation:
In order to get the number of classifications, you must multiply all the possibilities by each other in each trait. This is, each trait has two states (short or tall, round or wrinkled, yellow or green, white or purple) and are referred to as "pair of traits". These must be multiplied with the other pairs of traits. So, the number of different classifications of pea plants is:
the number of high states x number of shape states x number of peas color sates x number of flower color states = 2 x 2 x 2 x 2 = 16.

Explanation:
When fewer visual pigment molecules are available to absorb light (for example, when a person has a color weakness), which of the following nervous system responses occurs? A.Fewer signals of the weakly perceived color are sent to the brain. B.A normal number of signals of the weakly perceived color is sent to the brain, but each signal is less intense. C.The signals for the weakly perceived color are sent to the brain via other, more plentiful, pigments. D.Light molecules stimulate the cells to make additional pigment.
Answer:
A.Fewer signals of the weakly perceived color are sent to the brain.
Explanation: the brain is the seat of nervous coordination where nerve cells sends signals for processing. An individual with a weak color means a fewer signal for color production is sent to the brain this is due to low pigment it had hence fewer pigment molecule are available to absorb light. If the pigment is high the signal sent will also be high.

Why do you think scouts could hear better through the solid ground rather than
through the air?
Answer:
Sound travels better through solids than through air.
Explanation:
Think about being in the pool: you can hear a lot of things, albeit muffled a little. Or think about tapping a really long pole, and someone standing far away can hear the vibration or the noise while touching the pole.
Solids are more tightly packed together. Sound needs a medium to travel though, and anything with densely packed atoms is better than loosely packed. The hierarchy is solid > liquid > air. Kinda funny that we do most of our talking through air.

Consumers differ from producers in that unlike producers, consumers .b. cannot make their own food.
Producers can make their own food and energy, but consumers are different. Living things that have to hunt, gather and eat their food are called consumers. Consumers have to eat to gain energy or they will die. There are four types of consumers:
omnivores, carnivores, herbivoresdecomposers.How do consumers differ from producers?The producers generate food for themselves and others; consumers do not produce anything, instead eating producers, other consumers or both. Organisms that eat only producers (i.e., plants) are called herbivores. Animals that eat only consumers (i.e., meat) are called carnivores.

Which type of inheritance best explains the child’s hair type?
A
codominance because the child’s hair type is a blend of the parental hair types
B
codominance because both the male and the female carry the gene for hair type
C
incomplete dominance because the child’s hair type is a blend of the parental hair types
D
incomplete dominance because both the male and the female carry the gene for hair type
Odpowiedź:
A) codominance because the child’s hair type is a blend of the parental hair types.
Wyjaśnienie:
AA - curly hair
aa - straight hair
Aa - qualities AA + qualities aa = Wavy hair
The type of inheritance that best explains the child’s hair type is codominance because the child’s hair type is a blend of the parental hair types. The correct option is A.
What is inheritance?Inheritance is the transfer of genes and characteristics from the parent generation to the offspring. It is done in sexual reproduction. The traits of the mother and the father are transferred into the child.
Codominance is a type of inheritance in which the traits of the father and the mother get blended and a third different type of trait is shown in the offspring.
Here, the father has straight hair, and the mother has wavy hair, but the male child shows the hair is wavy hair. This shows the process of codominance in the child.
AA - curly hair
aa - straight hair
Aa - qualities AA + qualities aa = Wavy hair.
Thus, the correct option is A. codominance because the child’s hair type is a blend of the parental hair types.

All words will be used at least once and most words will be used more than once.A) diploidB) mitosisC) meiosisD) sister chromatidsE) haploidF) homologous chromosomes1) A male giant panda has 42 chromosomes in its skin cells. This represents the _________ chromosome number. As the animal's old skin cells die and slough off, cells nearby divide through _________ to produce more skin cells. 2) Germ cells within the animal's testicles undergo _________ to replicate themselves and _________ to produce sperm. 3) The cells produced by mitosis in this panda have a _________ chromosome number and are produced after _________ are pulled apart into separate daughter cells.4) The cells produced by meiosis I in this panda have a _________ chromosome number and are produced after _________ have been pulled apart into separate daughter cells. 5) The cells produced by meiosis II in this animal have a _________ chromosome number and are produced after _________ have been pulled apart into separate daughter cells.
Answer:
1. diploid ,Mitosis
2. mitosis, meiosis
3. diploid, sister chromatids
4. haploid, homologous chromosome
5. haploid, sister chromatids
Explanation:
1. The Giant Panda has 42 chromosomes but these chromosomes exist in the form of homologous pairs therefore the Panda are diploid organisms. The somatic cells of the Panda undergo mitosis like skin cells.
2. The Germ cells are present in the testicles of the Panda which makes an exact copy of themselves by mitosis but these germ cells undergo meiosis to produce sperms.
3. The Mitotic division forms two daughter cells with the same genetic material because the sister chromatids of homologous chromosomes move to the opposite pole.
4. The meiosis I am also known as reductional division as the homologous chromosome separate and move to opposite poles during meiosis I and the ploidy changes from diploid to haploid.
5. During meiosis II, the sister chromatids of a chromosome separate and move to the opposite poles as a result of this the haploid cells are formed.
A student plays football outside on a hot day and lost a significant amount of water in sweat. How will this affect his blood volume?
A.Blood volume decreases
B. Blood volume stays the same
C. Blood volume increases
Answer:
A.Blood volume decreases
Explanation:
Blood volume refers to the fluid substances including blood circulating in the body via blood vessels. The blood volume must be optimal in order to ensure that every organ in the body gets an ample amount of blood. One of the things that can result in alteration of the normal blood volume is DEHYDRATION, which is the loss of water from the body.
Dehydration decreases the blood volume because the water content in the blood becomes decreased as water is lost, which would have detrimental effects on the body because the blood pressure (force at which blood flows) will be reduced.
This is the case of the student in this question that loses a significant amount of water as sweat when he undergoes exercise in a hot weather condition. The loss of water will result in the decrement of his blood volume.
Which of the following is the best definition of the term genotype?
A genotype is a feature in the genes. I know this since a pheno is a physical trait while geno meaning gene is a trait in the genes that can't be seen.
The genotype refers to an organism's entire genetic makeup, including all of its inherited genes.
What is a genotype?It represents the underlying genetic information that determines the traits and characteristics an organism will have, such as eye color, height, and susceptibility to certain diseases.
The genotype is influenced by the combination of genes passed down from parents and can also be affected by mutations or changes in the DNA sequence. The genotype serves as the blueprint for an organism's development and can impact its phenotype, or observable traits and characteristics.

How do organims form carbon films
Answer:
Organisms form carbon film when sediments cover the organisms and decay of organisms form hollows.
Explanation:
Answer:
Organisms form carbon film when sediments cover the organisms and decay of organisms form hollows.
When an organism is covered by sediment, it begins to decay. When decaying, the organisms release a gas. This process in turns leaves a thin film of carbon that preserves parts of the organisms.
