1) Amino acids. Option B.
2) Phosphorus. Option D.
<h3>What are proteins?</h3>
Proteins are macromolecules made up of 2 or more amino acid units linked together by peptide bonds.
According to the passage, antibiotics work by breaking down the cell water proteins of bacteria. When proteins are broken down, they are broken into their component amino acids.
Therefore, when the researchers examine the phagocyte, the presence of amino acids would be an indication of the effectiveness of the antibiotics.
Amino acids are made up of elements such as nitrogen, carbon, oxygen, and hydrogen. Thus, if the researchers examine the monomers present in the phagocytes, all these elements should be found. Except for phosphorus.

#SPJ1
Answer:
Tundra
Explanation:
Permafrost is a layer just beneath the surface of the ground that never thaws.
Answer choice: [C]:
_________________________________________
V = d / t = 1800 mi / 40 min = 180 mi / 40 min = 45 mi / min .
Which very well could be "Answer choice: [C]: 45 m/min" ; except, this answer choice may have been written incorrectly—and should read:
"45 m/min."
________________________________________________________
Now, notice that all the answer choices given are in "meters" per (unit time—seconds or mins.
So, we need to convert:
45 mi. to "meters", or "m".
______________________________________
Note the following conversions:
_______________________________________
1 mi. = 1750 yd
______________________________________
3 ft. = 1 yd.
____________________________________
1 m = 3.2 ft.
_____________________
So, 1 mi. = ? m ;
_____________________
1 mi * ( 1760 yd/ mi) * (3 ft / 1 yd) * ( 1m / 3.2 ft) = _?_ m ?
_____________________________________________________
On the "left hand side" , the units of "mi", "yd", and "ft" ; cancel to "1" ;
____________________________________________________
and we are left with:
______________________________________
[(1760 * 3)] / [(3)*(3.2)] m = (5280 / 9.6) m = 550 m .
______________________________________________
So, we have: 550 m / min ; which match NONE of the answer choices.
However, it is possible that choices A or B, which are given in "m/sec" (meters per second); are among the correct choices.
____________________________________________
So, we convert: 550 m / min to: "m / sec " ;
______________________________________
( 550 m/ min)*(1 min/ 60 sec) = (550/60) m/sec = (55/6) m/ sec
= 9 1/6 m / sec .
_____________________________________________________
which is: None of the above.
______________________________________________________
Unless the answer choices were written incorrectly.
Answer:
it can be any if u give an explanation to support it
Explanation:
but i would say A as it requires lots of advanced medical technology designs to come that far as it can be quite expensive
hope this helps
i would appreciate it if u can heart and like my answer and maybe even give it 5 stars or brainliest pls i beg u thx !!! : )
The answer choices to this question are:
<span>a.
</span>Learned
helplessness.
<span>b.
</span>Stimulus
discrimination.
<span>c.
</span>Aversive
conditioning.
<span>d.
</span>Vicarious
learning.
The best answer choice is:
<span>a. </span>Learned
helplessness
<span>Explanation: Learned helplessness was studied by
Seligman as a potential animal model of depression. Learned
helplessness occurs when people or animals feel helpless to
avoid negative situations. Martin Seligman first observed learned
helplessness when he was doing experiments on dogs. He noticed that the dogs
didn't try to escape the shocks if they had been conditioned to believe that
they couldn't escape.</span>
