Answers
Answer:
(3)
Explanation:
I believe 3 would be the answer here because when interacting with a salt solution, plant cells will look like that. Hope this helped!
Diagram 3 of the cell will represents cell's appearance after being kept in 15% salt solution.
This will happen because of exosmosis in which the water will move out of the cell causing to to get shrink called plasmolysisWhat is osmosis?It is the process of movement of solvents through a semi- permeable membrane from region of lower solute concentration to higher solute concentration.
There are three types of osmosis:-
Isotonic:- The solutions bring compared have equal concentration of solutesHypotonic:- The solution with lower concentration of solutesHypertonic:- The solution with higher concentration of solutesTo know more about osmosis here

the presence of a lophophore in a newly discovered species would suggest that the species ________.
Answers
Answer: the answer is has an exoskeleton
The lophophore is the feeding organelle in aquatic organisms. Its presence in a species suggests that the species is a suspension feeder. Thus, option D is correct.
What are lophophores?
Lophophores are the feeding organelles present in the marine invertebrates like Brachiopoda, Hyolitha, etc., of the Lophophorata group. They are used for respiration, brooding, and collecting food.
Suspension feeders use these lophophores to collect and feed on the suspended organic matter and particles in the water. Lophophorates are a major example of suspension feeders.
Therefore, the presence of the lophophores suggests the species to be a suspension feeder.

if I subtract 20 from my number, then square the result, I get the same answer as if I square my number, then subtract 20 from the result
What is my number and how do you work it out?
Answers
The value of the unknown number is 10.5.
Let the unknown number = x
When 20 is subtracted from the number and the result is squared which is equal to the square of the unknown number minus 20:
(x - 20)² = x² - 20
expand the equation;
x² - 40x + 400 = x² - 20
collect similar terms together;
x² - x² - 40x = -20 - 400
-40x = -420
[tex]x = \frac{420}{40}\\\\ x = 10.5[/tex]

2.) What is the start codon? What are the 3 stop codons?
Answers
The amino acid sequence here is Met-Ser-Asp-Trp. The start codon is AUG, while the three stop codons are UAG, UAA, and UGA.
The triplets of nucleotides or codons in mRNA determine the order of amino acids that will be added to the protein during translation.
The start codon in the genetic code is AUG and it encodes for the amino acid methionine (Met).
The 3 stop codons in the genetic code are UAG, UAA, and UGA. These codons do not code for an amino acid.

A elephant cell has 20 chromosomes. how many chromosomes will the cell have just before mitosis begins in the elephant cell?
Answers
The elephant cell will have 20 chromosomes.
Cells undergo interphase before getting to the mitotic phase. At the S phase of the interphase, the amount of DNA in the cell is double by replication. However, the number of chromosomes remains intact.
Thus, the cell gets to the mitotic phase with the same number of chromosomes that is usually present in normal vegetative cells of the animal.

Smaller single-celled organisms have a high surface area to volume ratio, which allows them to rely on oxygen and material diffusing into the cell (and wastes diffusing out) in order to survive. The higher the surface area to volume ratio they have, the more effective this process can be.

Answer these questions about making a yogurt.
1) why is the milk pasteurized at the start of the process?
2) Why is the mixture of milk and bacteria incubated at 45 °C?
3) what causes the milk to thicken?
4) why does fermentation eventually stop?
5) Explain how making yogurt is a way of preserving the nutrients from milk.
Answers
It should be noted that milk is pasteurized at the start of the process in order to kill bacteria.
The mixture of milk and bacteria is incubated at 45 °C to kill the bacteria.The drop in pH causes milk to thicken. Fermentation is stopped when the alcohol concentration rises to a point where it kills the yeast cells.Lastly, making yogurt is a way of preserving the nutrients from milk as the bacteria ferment the milk thereby turning the lactose sugars to lactic acids.
