11. A. Ovulation.
12. Semen.
13.The fluid--to some degree--helps protect the sperm from the acidic environment of a woman's vagina, which could otherwise damage and kill said sperm.
14. During the menstrual cycle, the endometrium grows to a thick, blood vessel-rich tissue lining, representing an optimal environment for the implantation of a blastocyst upon its arrival in the uterus; the body also begins to prepare for ovulation again.
15. Both the testes and the ovaries produces entities needed for the process of reproduction. But while the ovaries create eggs, the testes create sperms.
16. On the 7th day; on the 21th day.
17. C. The amniotic sac.
18. The umbilical cord.
19. The germinal stage, the embryonic stage, and the fetal stage.
20. two eggs; a single egg.
21. Since the pituitary gland produces hormones that stimulating all the other hormone-producing glands to produce their own hormones, that tumor could potentially causes the body to function incorrectly: For example, the body could not produces the required hormones needed for the body to start producing sperms/eggs, preventing the person's ability to reproduce overall.

Answer: Compact bone is dense and composed of osteons, while spongy bone is less dense and made up of trabeculae. Blood vessels and nerves enter the bone through the nutrient foramina to nourish and innervate bones.
Explanation: Sup. Hope dis helps u
ddNTPs have a hydrogen at 3' position which terminates synthesis of DNA.
ddNTPs is the abbreviated form for dideoxynucleotides triphosphates. They are known as chain elongating inhibitors. The Sanger method is a sequencing technique that is used to increase the number of DNA copies. The DNA synthesis requires magnesium ions, a single-stranded DNA template, oligonucleotide primer, and nucleotide precursors like dATP, dGTP, dTTP, and dCTP. Also, DNA polymerase is required which is an essential component for DNA synthesis.
The Sanger sequencing method is a significant process evident by its use in Human Genome Project which helped scientists in sequencing the human genome. The small sequenced fragments are joined together to form large regions subsequently forming chromosomes.

Answer:
The student has observed That artificial fertilizer makes his plants grow faster and taller than plain soil. He knows that compost is a natural fertilizer. So, he infers that compost will make his plants grow faster than they grow in plain soil. that artificial fertilizer makes his plants grow faster and taller than plain soil. He knows that compost is a natural fertilizer. So, he is first that compost will make his plants grow faster than they grow in plain soil
