Explanation:
-the cell would shrivel because the water solution is hypertonic.
In passive diffusion, the small water molecules can move across the phospholipid bilayer . This layer acts as a semi-permeable membrane; its hydrophilic heads are attracted to water while its water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.
Thus the water will move from an area of high concentration (hypertonic) to an area of low concentration (hypotonic), until the system reaches a steady state called equilibrium- after this, there will be no net movement of water. Similarly via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid by layer this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Answer:
Human activity can affect the amount of carbon in the atmosphere. When fossil fuels like oil, coal, and natural gas are burned, carbon dioxide is released into the atmosphere as waste.
Explanation:
It has one very large moon that is almost half the planets size
so the answer would be A
Amino acids that must be obtained from foods in order for the body to function properly are called <u>essential amino acids.</u>
<u></u>
- The body is unable to produce essential amino acids. They must therefore originate from food.
- Organic substances known as amino acids are primarily made up of nitrogen, carbon, hydrogen, and oxygen.
- Twenty distinct amino acids are required by your body for growth and optimal operation. Despite the fact that all 20 of these are crucial for your health, just nine are considered essential.
- These include <u>valine, tryptophan, isoleucine, leucine, lysine, methionine, phenylalanine, and threonine.</u>
- While your body may produce non-essential amino acids, it is unable to produce essential amino acids; therefore, you must obtain them through diet.
- Animal proteins including meat, eggs, and poultry are the richest providers of necessary amino acids.
- But some plant meals, such edamame and tofu made from soy, do contain all nine essential amino acids. They are "complete" sources of protein.

Answer:
a. autotriploid of species A: 63 chromosomes
b. autotetraploid of species B: 96 chromosomes
c. allotriploid from species A and B: 1) 66 chromosomes and 2) 69 chromosomes
Explanation:
<u>For a.</u>
this species will have 3 haploid sets of chromosomes ('tri' means 3)
one haploid set = 21
21 × 3 = 63 chromosomes
<u>For b.</u>
this species will have 4 haploid sets of chromosomes ('tetra' means 4)
one haploid set = 24
24 × 4 = 96 chromosomes
<u>For c.</u>
there are two ways to do this:
1) two sets of chromosomes from species A and one from species B
42 + 24 = 66 chromosomes
2) one set of chromosomes from species A and two from species B
21 + 48 = 69 chromosomes
Hope that answers the question, have a great day!
