1. These four factors can effect ways evolution occur:

<span>1.) Mutation 
2.) selection
3.) Gene Flow
4.) Genetic Drift 

2.  </span>In biology, a mutation is the permanent alteration of the nucleotide sequence of the genome of an organism, virus, or extrachromosomal DNA or other genetic elements.

Selection, in biology, the preferential survival and reproduction or preferential elimination of individuals with certain genotypes by means of natural or artificial controlling factors.

In population genetics, gene flow is the transfer of alleles or genes from one population to another.

<span>Genetic drift  is the change in the frequency of a gene variant in a population due to random sampling of organisms. </span>

The medial cord is medial to the axillary artery and is formed by the ______ division of the inferior trunk; it contains portion
SpyIntel [72]

The medial cord is formed by the anterior division of the inferior trunk.

It contains portions of nerves C8-T1.

             The medial cord is present in our neck and is a part of the brachial plexus. It is formed by the anterior division of the lower trunk. It is called the medial because it is medial to the axillary artery.

              The medial cord leads to the formation of the medial pectoral nerve, medial cutaneous nerve of the arm, and medial cutaneous nerve of the forearm.

               The nerves labeled as C refer to the nerves affecting the motor system in our neck and upper limb. Thus nerves from C8 work for the motor conventions of our upper limb and neck.

              The nerves labeled as T are spread over our chest, shoulders, and hands. Thus, the nerve T1 works in the upper part of our body.

What letter represents summer where you live?
AURORKA [14]

I live in letter D in summer and letter B in winter.

<h3><u>Explanation:</u></h3>

In the diagram the letter D represents the summer solstice and the letter B represents the winter solstice. But the letter A and C represents the equinoxes that are present in the month of March and September. Here in India the country lies above tropic of Cancer. So the condition here is like the temperate region. So during summer the sun's rays directly fall on the country as well as during winter the country receives oblique sun rays. Thus from the diagram we can see see that the letter B represents the condition of earth when the sun's rays are not directly falling on earth. So it's winter solstice .

In the letter D we can see that the earth is going through the summer solstice because sun's rays are directly falling on the earth. So it's summer at that time.

Explain why a sound wave cannot travel in a vacuum?
Leto [7]
Sound cannot travel through a vacuum. A vacuum is an area without any air, like space. So sound cannot travel through space because there is no matter for the vibrations to work in.

Discuss 3 different types of mutations that can happen
Brums [2.3K]

Answer:

Explanation:

Un cambio en la secuencia de bases en el ADN o ARN se conoce como mutación . ¿La palabra mutación te hace pensar en ciencia ficción y monstruos con ojos de insecto? Piensa de nuevo. Todos tienen mutaciones. De hecho, la mayoría de las personas tienen decenas o hasta cientos de mutaciones en su ADN. Las mutaciones son esenciales para que ocurra la evolución. Son la fuente principal de todo el material genético nuevo -nuevos alelos - en una especie. Aunque la mayoría de las mutaciones no tienen efectos en los organismos en que ocurren, algunas mutaciones son beneficiosas. Incluso las mutaciones dañinas rara vez causan cambios drásticos en los organismos.
