Follicle stimulating hormone (FSH) and Luteinizing hormone (LH) are Gonadotropins stimulated in the gonads. In females, they are located in the ovaries. They are not needed for life yet important for reproduction. Progesterone which is being secreted in corpus luteum is needed for maintenance of pregnancy thus if a female has a low FSH and LH it will affect the chance of her be pregnant.
Answer;
Population; physiological modifications at the individual level.
The adaptation of the sled dog best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.
Explanation;
-The bodies of sled dogs are covered with two coats of hair that work together to provide a double layer of warmth. The under layer is very short and the dog sheds it in the spring to keep from overheating during warmer temperatures.
-During the colder winter months, this under layer works as an insulator against the dog's skin to keep his body warm and his core body temperature consistent. This adaptation best describes adaptation at the population level while the dog exposed to seasonal colder temperatures has physiological modifications at the individual level.
They both tried to explain evolution, but Darwin was able to support it with evidence.
Hope this helps!
