The cells on Tina's burnt shoulder peeling away is an example of apoptosis, which is the programmed cell death that occurs in multicellular organisms.
The cells on Tina's burnt shoulder peeling away a week later is an example of a process called apoptosis.
Apoptosis is the programmed cell death that occurs in multicellular organisms. It is a natural process in which cells that are damaged, infected, or no longer needed undergo a controlled self-destruction.
In the case of Tina's sunburn, the damaged skin cells are being shed to make way for new cells to replace them and facilitate the healing process.

the following is NOT a function of
these?
A. allows the strand to leave the nucleus
B. helps the strand attach to a ribosome to be
translated
C. signals that introns need to be spliced out
D. protects the strand from enzymes
Answer: The answer is C
Explanation: The answer is signals that introns need to be sliced out, I got it right!
C. signals that introns need to be spliced out. The 5' cap and the poly A tail of an RNA molecule serve to allow the molecule to exit the nucleus, attach to a ribosome, and protect from degradation. They do not signal for introns to be spliced out.
The RNA molecule has a 5' cap and a Poly A tail at the 3' end. These modifications play a few key roles in the functionality of the RNA molecule but the statement 'signals that introns need to be spliced out' (option C) is NOT one of the functions of these modifications.
The 5' cap allows the RNA to exit the nucleus and attach to a ribosome, while the poly-A tail helps stabilize the RNA, aids in the exit from the nucleus, promotes translation, and protects the RNA strand from enzymes that degrade RNA from the 3' end. Neither of these modifications signal for introns to be spliced out, that is primarily the function of spliceosome complex which recognize specific site sequences within the RNA.

Answer:
the gland is pancreas
Explanation:
a nitrogen gas - nitrate — ammonium - nitrite
b nitrogen gas - nitrite -nitrate - ammonium
C nitrogen gas - ammonium - nitrite - nitrate
d nitrogen gas - ammonium - nitrate - nitrite
The nitrogen cycle which is converted to an intermediate, is generally used by the organism at certain levels, hence option c nitrogen gas, ammonium, nitrite, nitrate is correct.
The nitrogen cycle in the biogeochemical cycle converts nitrogen into various chemical intermediates as it cycles into the air, terrestrial, and marine environments.
The nitrogen conversion processes occur through both biological and physical mechanisms. Fixation, ammonification, the first two steps, nitrification, and denitrification are all important processes in the nitrogen cycle.
The bulk of the Earth's atmosphere contains (78%) majorly composed of atmospheric nitrogen, make the primary source of nitrogen.
Therefore, option c begins with nitrogen gas, ammonium, nitrite, and nitrate in the correct order.

Vitamins refers to the components, which the body requires to develop and grow normally. There are in total 13 vitamins required by the body. These are classified as food soluble and water soluble vitamins.
It is generally advised to consume vitamins on a daily basis because the body has limited tendency of storage for various vitamins. Thus, they should be consumed on a regular basis in the diet.
