Answer:
Through simple diffusion, down the concentration gradient.
Explanation:
The phospholipids of the membrane are amphipathic with hydrophillic heads and hydrophobic tails. Other polar molecules cannot go through this hydrophobic interior. Since small uncharged lipids are non polar and hydrohobic, they are able to go through the membrane without the help of transport proteins. Therefore, the last two options can be ruled out because facilitated diffusion includes the use of a protein. Diffusion involves molecules moving down the concentration gradient so the second option can be ruled out.
Birds because they spread seeds
The correct answer is
offspring
The answer is both in males and females; only in males. Males
have one Y chromosome and one X chromosome, while females
have two X chromosomes. In mammals, the Y chromosome controls a
gene which is the SRY, which produces embryonic improvement as a male. The Y chromosomes of males and
other mammals also contain other genes needed for normal sperm production.
