First thing is Male gametes are called sperm and Female gametes are called eggs. So some physical differences are that the eggs are spherical in shape, much larger then sperm, and are immobile (they stay in the female reproductive organ during fertilization). Sperm are smaller, are in a cone shape, and have tails so the could move to the egg during fertilization.
The wings are adapted so they can hover and feed off of flowers.
The beak and tong is modified to extract nectar from flowers with long flower corollas.
Answer: Water can hold an unlimited amount of oxygen.
Explanation:
Water cannot hold an unlimited amount of oxygen because it would get to a point where it is saturated as it needs to hold Hydrogen as well. Air on the other hand, has significantly more space for oxygen as it contains only 21% and can keep taking more.
Underwater organisms need oxygen for respiration and a small decrease in the oxygen available in water affects aquatic life because they rely on it to survive.
