The amino acid sequence of a protein which is referred to as its primary structure determines the structure or folding pattern of that protein
The answer to this question is that two different neutral isotopes of
the same element will have the same atomic number. This is due to them
having the same number of protons, and it is these protons which
determine the atomic number. However, these istotopes will have
different masses due to a difference in the amount of neutrons.
A tympanic membrane, (is also called a tympanum), is the circular patch of skin directly behind the frog’s eye that we commonly call an eardrum. It functions much like our’s does.
The tympanum sends sound waves to the middle of the war then to inner ear, which allows a frog to hear both in the air and below water.
Answer:
C
Explanation:
First off, humans are considered animals, and since animal cells don't have chloroplasts, A and D are immediately incorrect. B is incorrect because lysosomes eject enzymes that digest materials in the cell, and to heal skin, you dont need to digest anything/ use enzymes to get rid if materials. That means the answer is C. The nucleus is the control center for the cell, so it tells the cell what to do. The mitochondria creates energy for the cell, and since it takes energy to heal, this answer is correct. (Tip- I find that using process of elimination in biology questions helps a lot.) Good luck!
The quiver tree faces various problems due to climate change and drought periods.
The population of this plant tries to avoid the unfavorable environmental conditions by shifting their growing range towards the poles, or more precisely away from the heat of the equator.
