Hormones trigger facial hair growth in a maturing male <u>physical & sexual systems</u> systems
<u>Explanation:</u>
When a male attains puberty the androgen's take control and regulate the male physique development. This puberty changes triggers the sex hormones.
After 12 years their testosterone hormones start working on the hair follicle which replaces the thin tiny vellus hair to thick black and hoarse hairs. Eventually the hormone felicitates growth of hair in his face, under arm and leg.
Men with levels of testosterone and dihydro testosterone or DHT is the major driving factor that causes the growth of facial hair.
Answer:
In order for polar compounds to enter into the hydrophobic space of phospholipid tails, it would need to break the many <u>hydrogen</u> bonds
Explanation:
In the presence of water, the hydrophobic tails tend to interact with each other, creating a hydrophobic space from which water is excluded and in which other hydrophobic molecules can be trapped, while the polar head interacts with water, and is solvated, preserving the hydrophobic part from all contact with water. For a hydrogen bridge to form, a molecule that has hydrogen attached to an atom of high electronegativity and another molecule that has another electronegative atom with high electron density (that is, a negative partial charge) is required. Water molecules in the bulk of the body of water maintain multiple interactions with other molecules through an extensive network of hydrogen bridges, so for polar compounds to enter, it would be necessary to break many of these bonds.

Answer:
375 million-year-old fish, a large scaly creature not seen before, that they say is a long-sought "missing link" in the evolution of some fishes from water to a life walking on four limbs on land.
In addition to confirming elements of a major transition in evolution, the fossils are widely seen by scientists as a powerful rebuttal to religious
Explanation:
on closer examination, scientists found telling anatomical traits of a transitional creature, a fish that is still a fish but exhibiting changes that anticipate the emergence of land animals — a predecessor thus of amphibians, reptiles and dinosaurs, mammals and eventually humans
Answer:
Flatworms,crabs and starfish are classified as Invertebrates.This is due to the fact that they neither possess nor develop a vertebral column, derived from the notochord.
