<span>Stratum Basale, being the deepest stratum of skin, will be supplied with the highest levels of oxygen from the blood. The Stratum Basale is constantly renewing and must be supplied with oxygen in order to keep renewing. The other stratus are more superficial and further from the blood source and also do not require quite as much oxygen.</span>
The correct options are as follows:
1. Human skin color variation is primarily determined by the type and amount of melanin pigment in the skin.
2. Human skin color variation likely evolved in response to differences in the intensity of sunlight around the world.
3. Human skin color evolve recently in hominid evolution, once some population of human ancestor migrated out of Africa.
The color of human skin is primarily determine by melanin. The intensity of the sun in the climate where one is living also affect the type of skin color that will dominate in a geographical area.
Answer:
First read the student guide to understand everything that will occur in this lab. Second read the safety guideline to ensure no one is harmed during this lab. Then gather your materials for the lab. After that section off your grass into 32 sections. Choose a quadrant and make some observations. Then choose a random sample area in your quadrant to estimate how many individual pieces of grass are present. Next, find the average height of the grass. Then, compare the data to quadrant #18. Plant your seeds. Count how many blades of grass are in your random sample area, and then calculate the estimated number of blades in your quadrant. Find the average height of the grass. Compare your data once again to quadrant #18, which is in the control group. Record the height of all the plants and calculate the average height for each type of plant. Compare this data with the data from quadrant # 18. Combine the data from all quadrants, and then compare the data from the experimental group to the control group. Make sure you record all your data.
