The question refers to the following table, which compares the percent sequence homology of four different parts (two introns an

d two exons) of a gene that is found in five different eukaryotic species. Each part is numbered to indicate its distance from the promoter (for example, Intron I is the one closest to the promoter). The data reported for species A were obtained by comparing DNA from one member of species A to another member of species A.
Regarding these sequence homology data, the principle of maximum parsimony would be applicable in ________. (A) distinguishing introns from exons (B) determining degree of sequence homology (C) selecting appropriate genes for comparison among species (D) inferring evolutionary relatedness from the number of sequence differences

The question refers to the following table, which compares the percent sequence homology of four different parts (two introns and two exons) of a gene that is found in five different eukaryotic species. Each part is numbered to indicate its distance from the promoter (for example, Intron I is the one closest to the promoter). The data reported for species A were obtained by comparing DNA from one member of species A to another member of species A.

Regarding these sequence homology data, The principle of maximum parsimony would be applicable in Inferring evolutionary relatedness from the number of sequence differences.

What is principle of maximum parsimony?
Maximum A phylogenetic t
ree can be inferred using the character-based method of parsimony by reducing the total number of evolutionary steps needed to explain a given set of data assigned to the leaves.

Generally speaking, the parsimony principle states that it is preferable to use the simplest explanation possible to explain the data. Parsimony in phylogenetic analysis refers to the notion that a relationship hypothesis that calls for the fewest character changes is more likely to be accurate.

Therefore,

The principle of maximum parsimony would be applicable in Inferring evolutionary relatedness from the number of sequence differences.

List and explain the 4 different types of variables and explain them.
vagabundo [1.1K]

Answer:

independent, dependent, control

Explanation:

The independent variable is the variable that you change. For example, if we were growing plants and wanted to see if more sun made them grow higher, you would change the amount of sun that each plant is exposed to.

The dependent variable is what you measure. This <em>depends</em> on the independent variable. So, in our plant experiment, the height of the plant is the dependent variable.

Control. The control is what stays the same. So in our plant experiment, the amount of water, type of plant, type of soil, and all of these things would stay the same to insure that the results are equal.

If a parent with AB blood and a parent with
Vlad1618 [11]

Answer:

O blood is a recessive trait, so none of the children will have O blood. The genes for either type A or Type B will be determined by the egg/sperm being fertilized with the reproductive cell of the other parent. the probability of receiving either of the gene versions is 1/2, so half of the children will have A blood and the other half will have B blood

Radioactive materials that are high energy and will cause cellular and tissue damage are called:______.
s344n2d4d5 [400]

Radioactive materials that are high energy and will cause cellular and tissue damage are usually known as ; Alpha radiation.

<h3>What is Radioactive material and Alpha Radiation ?</h3>
  • Chemicals in the class of radionuclides (also known as radioactive materials) have unstable atomic nuclei. They stabilize themselves by altering the nucleus (spontaneous fission, emission of alpha particles, or conversion of neutrons to protons or the reverse).
  • For example, the Earth's crust naturally contains the radioactive elements uranium and thorium. These two elements slowly alter their forms over billions of years, leading to the production of decay byproducts like radon and radium. Energy is released during this process. Alpha radiation is one type of this energy.
  • Alpha particles, also called alpha rays or alpha radiation, consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus. They are generally produced in the process of alpha decay, but may also be produced in other ways.
