Answer:

The testes are male reproductive organs that produce and store (semen/sperm), which is the male gamete containing half of the DNA in somatic cells.

The typically 28-day process of egg release from the ovaries and, if fertilization does not occur, release from the body, is known as the (menstrual) cycle.

If two eggs are released and fertilized by two different sperm, then (unidentical) twins will occur.

If a hormone operates by entering a cell's nucleus and altering the expression of its DNA, then it is classified as a/n (important) hormone.

Once sperm cells are mixed with seminal fluid to provide protection and nutrition, this mixture is known as (semen).

The bulbourethral and glands play an important role in providing additional fluids to semen production.

The first phases of a new zygote's growth through mitosis occur in the (uterus).

The (outer)germ layer will eventually develop into the skin and nervous system.

A fetus growing in the uterus does not eat food or drink water. Instead, important nutrients, antibodies, and molecules pass from the mother through the (umbilical cord).

Make a list, or write a short paragraph, that explains the major stages of pregnancy after fertilization, through childbirth. Provide as much detail as possible.

Answer:

sperm

menstrual

fraternal

steroidal

semen

prostate

fallopian tube

ectoderm

placenta

After fertilization of an egg by sperm in the fallopian tubes, a blastocyst forms and implants on the uterus wall. These cells then begin to differentiate. During gastrulation, the three main germ layers form (endo, meso, and ectoderms). During neurulation, the notochord and neural tube form. The neural tube must close to avoid birth defects or conditions. The amniotic sac forms, and the placenta forms to provide a link from the mother to the fetus through the umbilical cord. During months 4-6, bones replace cartilage and organs develop. In months 7-9 the fetus matures its lungs and central nervous system. Finally, oxytocin triggers childbirth, when uterine contractions push the baby from the vagina.

Question 2 of 10
Lyrx [107]

Answer:

Option-D

Explanation:

The small intestine is the part of the digestive system which is very long in its length but small in diameter. The small intestine begins after the stomach and the main parts of the intestine are duodenum, jejunum and ileum.

The small intestine is the main site for the digestion of chyme and absorption of the nutrients from the digested material. The food enters into the small intestine from the stomach in which the digestion of proteins begins.

In the stomach, the enzyme pepsin acts on the peptide bonds of the protein and break it down into the smaller proteins. Therefore, the food that enters the small intestine has already been broken down into smaller proteins.

Thus, Option-D is correct.
