Answer:
Hey there the answer would be D. Keratin is the pigment responsable for skin color.
Explanation:
A. The top layer of the epidermus is made of dead skin cells. The inner player has to be constatnly making more cells
B.The body procudes more melanin with stronger sunlight exposure. This results because the UV of the sun causes T-T dimers which is a type of DNA damage.
C. UV causes genetic mutation which can result in cancer if not fixed by the cell
D.Keratin is found in the epidermis and with thick layer of skin found in the hands and feet. Melainin is responsible for skin color.
I still didn't learn that but a guess would be Climate is a long-term model of weather in specific location or place. Thus, aspects of climate that are most important to forest ecosystem is the temperature and precipitation. Because. <span>1. Temperature determines the adaptable and environmental influences such as the sunlight, the biotic community and especially the photosynthetic mechanisms of plants which is responsible for making its own food.</span> <span>2. <span> Precipitation. Water is vital in many aspects of plants since it is one of the materials needed for plant’s food-making process.<span>

Answer:
Barr bodies are small bodies that are dark staining bodies that show the inactivated X chromosome, these sex chromatin bodies attach to the membrane of the nucleus of interphase cells.
One less of the total number of X-chromosome (n-1) represents the number of Barr bodies.
Then,
The number of Barr bodies with Klinefelter would be:
Klinefelter (47,XXY): (n-1) = (2-1) = 1 Barr body as here two X chromosome present.
Similarly, for
Turner (45,XO): (n-1) = (1-1) = 0 Barr bodies (X chromosome = 1)
Now, as per the question, the bar bodies for karyotypes given
47,XYY: (n-1) = (1-1) = 0 Barr bodies
47,XXX: (n-1) = (3-1) = 2 Barr bodies
48,XXXX: (n-1) = (4-1) = 3 Barr bodies
