Xelga [282]

Answer:

mitosis

Explanation:

The cellular process that enables the cells to grow and develop into tissue is mitosis.

Mitosis involves the division of the vegetative cells of the body and is important for the growth and development of organisms as well as in the healing of wounds or the replacement of damaged cells/tissues.

<em>Hence, in treating burns and other types of skin injuries, the cells of the skin are stimulated to divide rapidly by </em><em>mitosis</em><em> so as to replace the damaged cells due to the injury. By doing so, the injured area heals.</em>

A)Exons 2 and 3 must have the same number of nucleotides. B)Exons 2 and 3 must contain an integral number of codons (that is, th
Thepotemich [5.8K]

Answer:

Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.

Which choice best describes the parts of the water cycle? The sun's thermal energy causes water on the earth to evaporate. The w
Travka [436]

Answer:

The sun's thermal energy causes water on the earth to evaporate. The water vapor then condenses and forms precipitation. The precipitation then falls back to the surface of the earth.

Explanation:

<u>The water cycle is an illustration of how water continuously moves or circulates between the atmosphere and the various parts of the earth. </u>

<em>Evaporation of water from the surface of the earth by the thermal energy from the sun causes water to leave the surface of the earth into the atmosphere. When the atmospheric water vapor (humidity) at the upper strata of the atmosphere becomes high, the vapor condenses to form clouds which later forms precipitation that falls back to the surface of the earth.</em>

The ocean's tidal energy does not cause water to cycle on earth.
