PLEASE HELP<br> ME PLEASE
nikitadnepr [17]
Whales are closely related to hoofed mammals with an even number of toes, such as horse, because they evolved from them. Before whales were what we know them as today, they were relatively similar to horses. They used the water to flee from predators, and they evolved slowly to heighten their swimming ability, eventually becoming modern day whales. Fish have always been aquatic animals that have gills. Whales cannot breathe underwater, so they take in oxygen the same way a horse does. Also, both horses and whales are mammals that give birth to their offspring and are warm-blooded. Fish lay eggs and are cold-blooded.

Hope this helped! Please give brainliest! :)

Mammals produce milk to nurse their young. In humans, which hormone controls milk production?
DedPeter [7]

Answer: C. Prolactin

Prolactin is a hormone that controls milk production together with oxytocin. The anterior lobe of the pituitary gland secretes prolactin and the posterior lobe secretes oxytocin when a baby suckles at the breast. The level of prolactin in the blood slowly increases during pregnancy, and stimulates the growth and development of the mammary tissue, in preparation for the production of milk after delivery.

Moreover, Prolactin is in the highest level in about 30 minutes after the beginning of the feed, which is most important for producing milk for the next feed.

True or false the genotype of an organism constitutes its observable characteristics
iren2701 [21]
False

The genotype of an organism does not constitute its observable characteristics but rather its phenotype. A genotype of an organism is the genetic makeup of an organism while the phenotype is the visible characteristics.
It is, however, significant to understand that the phenotype of an organism is as a result of the interaction between the genotype and the environment.
