An organism is _______ for a gene if it has two copies of the same allele for the gene.
The genotype of an organism and the interaction of the genotype with the environment determine the organism’s _______, or observable characteristics.
The law of independent assortment states that the separation of alleles for one gene are independent of that of other genes, unless the genes are _______.
Mendel’s law of _______ governs which allele is expressed in an individual.
Respond to the following based on your reading.

In the previous section, you learned that the allele for brown eyes (B) is dominant, and blue (b) and green eyes (g) are recessive, while green eyes are dominant over blue eyes. What eye color would someone with the following genotypes exhibit? (a) BB, (b) Bb, (c) gb, (d) Bg, (e) bb.
Discuss the law of segregation and explain why each organism has two copies of the gene for each trait expressed.
What type of experiments did Mendel conduct, and what did he want to find out about the heritability of the seven traits he chose to study?

Answers

Answer:

1. Purebred (N.B: the exact word is considered a foul word)

2. Phenotype

3. Linked

4. Segregation

5) (a) BB- Brown eyes

(b) Bb- brown eyes

(c) gb- green eyes

(d) Bg- brown eyes

(e) bb- blue eyes

The other questions are explained below

Explanation:

1. A purebred organism is that which possess two copies of the same alleles in its genotype. An allele is a contrasting form of a gene. If the two alleles are the same, the organism is said to be purebred.

2. Phenotype of an organism is the observable characteristics of the organism. It is determined by the organism's genotype in interaction with its environment.

3. Mendel's law of independent assortment states that the alleles of a gene will separate into gametes independently of another gene unless the genes are linked. Linked genes are genes that are too close to each other on a chromosome and hence, do not sort independently. They're rather inherited together.

4. Mendel’s law of Segregation governs which allele is expressed in an individual. According to this law, an organism will express the allele it randomly receives from each parent. If an organism receives two different alleles, it will express the allele that is dominant. In other words, an organism will only express the recessive trait if it receives two recessive alleles from both parents.

5. a) BB- Brown eyes because the organism is purebred for the dominant (brown) allele

(b) Bb- brown eyes because the brown allele (B) will mask the expression of blue allele (b) and express itself.

(c) gb- green eyes because the allele for green eyes (g) is dominant over the allele for blue eyes.

(d) Bg- brown eyes because the brown allele (B) is dominant over the allele for green eyes (g), hence, it will mask its expression

(e) bb- blue eyes because the organism is purebred for the blue allele i.e. same recessive (blue) alleles in the gene.

6. The law of segregation as proposed by Mendel states that the alleles of a gene will separate into gametes during gamete formation (meiosis). This is done in such a way that each gamete contains only one allele of each gene. Hence, an organisms will contain two copies of a gene because they receive each copy (allele) from each parent during fusion of their gametes.

7. Mendel conducted an hybridization experiment i.e. a cross involving two individuals that possess different traits. He did this in order to find out how different traits/characteristics in organisms were transferred from one generation to another. Mendel chose the pea plant for his experiment because they could easily be manipulated for self and cross pollination. Mendel studied seven (7) different traits or characteristics in pea plants including height, seed shape, seed color, flower color etc.

It can be inferred from the passage that the time required to replenish muscle glycogen following anaerobic glycolysis is determined by which of the following factors? I. Rate of oxidative metabolism II. Quantity of lactic acid in the body fluids III. Percentage of glucose that is returned to the muscles

Answers

Answer:

Percentage of glucose that is returned to the muscles.

Explanation:

After intense physical activity, where glycogen reserves are consumed, the muscle acquires its resting and reactivation position, is where the organism that feeds the new reserves for the next physical activity is located.

Foods rich in carbohydrates identified as ATP or glucose in good quantities, but this depends on the amount of intake and the quality of the food, that is how when consuming these sources, the serum glucose values are metabolized, that is, increases glycemia and this promotes the release of insulin that is responsible for generating energy reserves with more complex chemical bonds such as glycogen.

Why did the author think e-skin could make better hearing aids? In your answer, explain how the ears connect to the nervous system

Answers

Answer:

The author thought this because e-skin might hold promise for use in soft, wearable hearing aids. Unlike conventional aids, soft devices are more comfortable because they mold to human skin. When the ear receives sound vibrations, there are hair cells in the cochlea that vibrate and translate the sounds into electrical signals. These electrical signals are transmitted to the auditory nerve, which transmits the information to the brain.

Answer:

Sound is one of the five major senses. The nervous system carries sound signals from sensory receptors to the brain. E-skin has many sensory receptors that can carry signals toward the brain, enabling us to react to sounds. Because e-skin is soft, scientists can use it to make effective hearing aids that are quite comfortable to wear.

what are the problems and the challenges in classifying living things​

Answers

Answer:

below

Explanation:

there are so many different kinds of living things that its so difficult to classify them as there would be too many classifications that it would become absurd to have only a few organsims in a single group. the role of classification is to organize as well as simplify so it proves to be a challenge when the subgroups branching from eukoryotes vs prokaryotes become too small and therefore it becomes a giant mess.  even the current classification system (taxonomy) is flawed.

The problems/challenges associated with classifying living things is : The challenge of having a very small number of living thing classified into a subgroup and having an enormous amount of subgroups.

Although the main reason of classification of organism is to organize/categorize every living thing into a suitable group as well as simplify the subgroups( this leads to having a lot of subgroups ). there is also a challenge whereby the subgroups become so small when trying to categorize every organisms following all the rules of taxonomy. while

Taxonomy is the science of classifying living things into different groups and subgroups following certain similar characteristics exhibited by the organism.

An example is : The subgroups of eukaryotes vs prokaryotes becoming  too small. because the rules of Taxonomy been followed.

hence the challenges are: very small number of living thing classified into a subgroup and having an enormous amount of subgroups.
