Melanin conveys some UV protection
ultra violate radition
UV is an environmental human carcinogen. It’s the most prominent and universal cancer-causing agent in our environment. There is very strong evidence that each of the three main types of skin cancer (basal cell carcinoma, squamous cell carcinoma and melanoma) is caused by sun exposure. Research shows that as many as 90% of skin cancers are due to UV radiation.
Do the experiment a couple more times until u see how it turned out then cancel out the wrong answers to simplify the correct trialed formula
Answer:
Hydrogen ion (H+) pumps work against their concentration gradient and therefore they need energy inputs from sources such as ATP
Explanation:
The hydrogen ion (H+) pumps are proteins that move protons across biological membranes. These pumps use energy in the form of ATP in order to generate a proton gradient on one side of the membrane. For example, in plants, H+ pump ATPases are able to generate an electrochemical gradient in the plasma membrane. In this case, the proton gradient is employed to drive secondary transport processes, thereby enabling the uptake of diferent metabolites such as nutrients, sugars, amino acids, etc., from the extracellular space.
Is called a climax community
