Answer:
A. Their bodies tend to take in too much water.
Explanation:
Osmoregulation is the maintenance of osmotic concentration inside the body cells and in the extracellular fluid by controlling the amount of water and salts. Organisms living in water can be divided into two groups: Some are osmoconformers which change the osmolarity of body fluids with respect to the surrounding medium. Some are osmoregulators which do not allow change in internal osmolarity and try to maintain it by various means.
If as osmoregulator is placed in fresh water environment then their body is hypertonic to their environment. Osmosis will occur which is the movement of water from low solute to high solute concentration. Thus the problems faced by such organisms would be:
- Entry of excess water
- Loss of body salts to outside.
Adaptations in such organisms would be:
- Body cover such as scales or adipose covers
- They do not drink more water
- Excess water is eliminated as dilute urine
- Special cells called ionocytes or chloride cells help in active uptake of sodium ions and chloride ions.
Answer:
0.60
Explanation:
q2 = 0.16;
q = 0.4
Using the formula: p = 1 − q,
P = 1 - 0.4
p = 0.6
or p = 60%

1). Thus, the syndrome is typically more severe in males because males have only one X chromosome, while females have two. It is unclear how changes (mutations) in the DNA structure of the gene lead to the clinical findings. There is no cure and no standard course of treatment for Coffin-Lowry syndrome.
Thermodynamics, the laws of gravitation
It’s cool that you found that! You can try identifying it by its luster, color, breakage, etc, Try getting a piece of paper or something, scrap it on the paper, and see what it leaves behind. That’s a way many scientists identify rocks/crystals. You can also google types of rocks and see if you find a match. You always need to look at its color, as the color is the most distinctive feature of a rock. If you’ve since all of these things and your very serious about it, you can try calling somewhere or someone who would know (like a scientist who studies rocks).
