Answer: The father determines the biological sex of a baby
Explanation: Human beings have two sex chromosomes, males have XY chromosomes whereas females have XX chromosomes. During fertilization, an egg from a woman fuses with a sperm cell from a man to form a zygote. Women have two X chromosomes (XX) and any point in time they can only release an egg bearing an X chromosome but males have one X and one Y chromosome, therefore they can either release a sperm cell with an X chromosome or a sperm cell with a Y chromosome. When an egg with X-chromosome fuses with a sperm cell with an X chromosome, the resulting baby is a female but when an egg with an X chromosome fuses with a sperm cell with a Y chromosome, the resulting baby is a male.
What makes the difference in both sexes is the Y chromosome from the man, therefore the father determines the biological sex of a baby.

Answer:
They are the monomers of the proteins.
Explanation:
When hundreds or thousands of amino acids join together, they create proteins, which are then used for many tasks in organisms, such as doing work in cells, help with DNA replication, etc. So, the monomer will be the amino acids, and the polymer will be the proteins themselves.
The third one is the correct answer. I hope this helps!
