B.
The Radio-ulna and digits of most primates and animals represents a homologous structure




An example of another internal structure is the genes.
The homologous chromosomes have the same genes in common. Each cell has at least two sets of chromosomes which one comes from one’s father also called as paternal chromosome and mother, called as the maternal chromosomes. These chromosomes are what makes the child obtain the characters and may depend on the traits the parents possess. Homologous chromosomes are not duplicated chromosomes or identical however, they are analogous or similar. The alleles for a specific characteristics isn’t the same but the same genes are in the same order.<span> </span>

A carbon atom can bond with other atoms in a variety of ways. Wich set of bonds would a typical carbon atom in a compound
notsponge [240]

Answer:

A carbon atom can form up to four covalent bonds as one carbon atom has four valence electrons (in outermost shell). It is a fact that the number of valence electrons in a atom determines the number of covalent bonds it will form. Thus, each electron in carbon atom is used to form four covalent bonds with various four atoms.

Explanation:

A bond between a carbon and hydrogen atom is a non-polar covalent bond. The non-polar covalent bond are the bonds between two atoms which share equal number of electron(s) with each other. Example: as in case of methane, where one carbon atom shares its 4 outer valence electrons with four hydrogens by sharing equal number of electron.

In contrast, polar covalant bond are the bonds between two atoms which share unequal number of electron(s) with each other. Thus these bonds are partially ionic.

Given a population that contains genetic variation, what is the correct sequence of the following events under the influence of
GuDViN [60]

Answer:

2. A change occurs in the environment.

4. Poorly adapted individuals have decreased survivorship.

1. Well-adapted individuals leave more offspring than do poorly adapted individuals.

3. Genetic frequencies within the population change.

Explanation:

The natural selection theory was developed by Darwin to explain how evolution occur within a population. The environment is in constant state of changes and always select for organisms that are better adapted to it.

Poorly adapted organisms gradually reduce from the population as a result of decreased survival while well-adapted individuals multiply and contribute more to successive generation.

Well-adapted individuals pass on the adaptive alleles to their offspring, eventually leading to a change in gene frequencies within the population.

Hence, the sequence of events is 2, 4, 1 and 3.

Describe at least one part of the experiment procedure you thought was essential for getting good results. Did you find that cer
atroni [7]

Answer:

Control environment is the most important procedures for getting good results.

Explanation:

The control environment for an experiment is the essential part for getting good results. In control environment, there is no or less chances of infestation from the external environment which can cause the results of the data more acceptable. So the scientists prefers laboratory for performing experiment as compared to outer environment. So in my opinion for getting better results, the control environment is the most necessary experimental procedure.

Yes, for getting better results I think there is a step that could have been added to the procedure is to follow the international standard procedures for taking the readings by the experimenter.

Which of the following best explains the role of a genetic counselor
stiks02 [169]
If I were hired as a genetic counselor to advise a couple about the odds of the couple having a baby with a genetic disorder and I wanted to order lab tests to be done on the pregnant mother to determine if the baby has a genetic disorder (amniocentesis)-what kind of test would be done? How would the test determine if the baby has a genetic disorder or not? If it is determined that the couple's baby has a genetic disorder, then what advice should I provide to that couple? Why? What if the couple went against my advice? Whose advice (mine-the genetic counselor representing science or the couple representing society) should be considered?
