Airida [17]
<h2>Axons </h2>

Explanation:

Axons cross from one side of the spinal cord to the other through the gray commisure

  • Each arm or extension of the gray matter in the spinal cord is referred to as a horn
  • Projecting towards the back of the spinal cord are the dorsal horns (or posterior horns)
  • Projecting towards the front are the ventral horns (or anterior horns)
  • In the thoracic and upper lumbar regions of the cord, an additional pair of side projections occur, which are called the lateral horns
  • A narrow band of gray matter known as the gray commissure stretches across of the center of the spinal cord and connects the two sets of horns
  • In the middle of the gray commissure is the central canal, which contains cerebral spinal fluid

A change in a sequence of DNA bases in a bacterial cell has resulted in a mutation. This mutation has increased the ability of t
Svetllana [295]

Answer:

The relative frequency of the mutation will increase as time passes.

Explanation:

This random mutation has, by chance, caused a phenotype that is beneficial to the bacteria. This mutation improves the fitness of the bacteria, as they are able to utilize more food sources. This reduces the chance of starvation and death of the cell. Therefore, cells with this mutation are more likely to survive, and for longer.

In times where nutrients are scarce, bacteria without the population will die off. But the bacteria with this mutation will be more likely to survive and pass on their genetic material. Therefore, over time, the frequency of this mutation will increase.

Which explanation provides support for continental drift theory?
Luba_88 [7]

Answer and explanation:

Among the main evidences of the theory of continental drift, we can mention the fit of the lines of the coasts of several continents, In addition to the similarity between several relief structures and rocks in different continents (such as mountain ranges found in South America and on the east coast of Africa).

There are also records of fossils of identical extinct plants, found on the African continent and also in countries like Australia, India and Brazil, for example.

Identical reptile fossils have also been found in Africa and South America, in addition to several correlations in the distribution of aquatic dinosaur fossils that lived in common areas of the ancient supercontinent.
