Mating is rarely random. Many organisms choose a mate for specific reasons - body size, coloration, antler size, feather length,

etc. Changes in allelic frequencies due to this non-randomness of mating is called Question 3 options: Hardy-Weinberg equilibrium. natural selection. genetic drift. gene flow.

Answer:

Natural selection

Explanation:

Sexual selection refers to the natural selection where the allele frequencies of a population are changed due to nonrandom mating between the individuals. Certain preferences for the mate by organisms result in sexual selection. It is mostly exhibited by females.

For example, peahen prefers the peacocks with elaborate tail features as their mate. The sexual selection also occurs when there is competition among the members of the same sex for a mate. This type of sexual selection is mostly exhibited by males and results in fighting and display.

Proteins are three dimensional molecules made of strands of amino acids (imagine a ball of string). There are 20 different amino
zlopas [31]

Answer:

A series of nonpolar amino acids would most likely be located in the interior region of the tridimensional molecule.

Explanation:

Proteins are formed by linearly arranged amino acids, each with a side chain: the R-group.

Of the 20 different amino acids that compose the proteins, about half of them -10- are non-polar. Their R-groups are not stable if they are in contact with water, meaning that non-polar amino acids are hydrophobic.

When proteins are synthesized, they acquire a three-dimensional structure that makes them more stable. Lineal polypeptides get folded and turn into a shape that makes them more stable in the environment and capable of accomplishing their biological role. When they are in an aqueous media, their bent shape leaves the hydrophilic R-groups in contact with water. The hydrophilic R-groups stick in the center of the polypeptide, facing the protein interior, and avoiding interaction with water.

ATP hydrolysis _______.
yaroslaw [1]

Answer:

The correct answer is to ADP and Pi is the most common mechanism for transferring free energy to drive endergonic reactions.

Explanation:

Many endergonic reactions(the free energy change of these reactions are highly positive) proceed in a thermodynamically unfavorable manner.

     To make those reactions thermodynamically favorable,these reactions are coupled with hydrolysis of high energy compound such as hydrolysis of ATP to ADP and Pi.

    As a result the free energy change of those reactions becomes negative which allow those reactions to proceed in a thermodynamically favorable manner.

Explain why the ratio of motor neurons to muscle fibers is greater in muscles that control eye movement than in postural muscles
EleoNora [17]

Answer:

The muscles of the eye cover a greater number and in turn carry out greater fine motor skills.

Explanation:

Alpha motor neurons are neurons that invent the skeletal muscle, that is, striated, so that through the motor plate that is the unit that unites them, an action potential is transmitted that contracts the sarcomeros of the elastic fibers and the z lines. come closer, each eye movement is much more precise than the locomotion of the lower limb, which carries greater innervation in each muscle bundle due to the specificity of the movement, this is how more alpha motor neurons are required to mobilize the eye than a leg.

The process of photosynthesis can be represented by the chemical formula A) C6H12O6 + 6O2 → 6CO2 + 6H2O + energy B) C6H12O6 + 6H
miv72 [106K]
C.
6CO2 + 6H2O + Light -> C6H12O6 + 6O2

Light is needed as energy in order for photosynthesis to occur. Photosynthesis converts carbon dioxide and water into oxygen and glucose.
