"Answer DThe outermost layer of old epidermal cells are sloughed off and replaced every 15 to 30 days. The sebaceous glands secrete sebum which maintains the skin pH between 3 and 5. Bacteria which metabolize sebum live as opportunistic pathogens on the skin and cause skin infections."
Answer:
are most likely due to the fact that and are most likely due to the increased
Answer:
d. None of these
Explanation:
Probably the identical sequence found in both species<em> </em>is an<em> ultraconserved sequence. </em>
An <u>ultraconserved element</u> is a particular DNI sequence that remains exactly the same through evolution, with almost no modification, and that is shared by at least two completely different species.
These ultraconserved DNI portions seem to be highly essential for life. However, their function could not be determined yet. Most of them do not codify for proteins, but they could play a significant role in gene regulation.
It is suggested that these sequences are so significant for life that only a small change would compromise the organism´s aptitude.
Hi there!
Although there are only 20 amino acids, these amino acids can combine into an innumerable amount of combinations to form different and unique proteins.
<span>In case that doesn't make sense to you, I'll provide you with an analogy. You could be provided with 20 different LEGO bricks to work with. While there may only be 20 bricks, these bricks can combine into a vast amount of different formations, structures, etc. Amino Acids work in the same way.</span>
Chloroplast, its where photosynthesis happens and the cell wall which only plants fungi and bacteria have.
