Explanation:

Question 1

• Development of the fetal immune system: Proteins (like antibodies, immune - related proteins) are essential for building the immune system.
• Growing fetus’s bones and teeth: Calcium and phosphorus are more related to bone and tooth growth, not protein.
• Growth of fetal tissue and organs, especially the brain: Proteins are the building blocks of tissues and organs, including the brain (e.g., structural proteins, enzymes).
• Production of DNA: DNA production involves nucleic acids, but proteins (enzymes) are needed for the processes of DNA replication and synthesis.
• Proper building of breast and uterine tissue to support the growing fetus: Proteins are essential for tissue growth and repair, so they are needed for building breast and uterine tissue.

So the correct options are: Development of the fetal immune system, Growth of fetal tissue and organs, especially the brain, Production of DNA, Proper building of breast and uterine tissue to support the growing fetus.

• Option A: In the first trimester, hormone levels (like hCG) are high and cause nausea. In the second trimester, hormone levels level out, which leads to a decrease in nausea.
• Option B: Understanding how to eat does not directly cause a decrease in nausea related to pregnancy.
• Option C: Fetus growth is not the main reason for the decrease in nausea.
• Option D: Personal adjustments do not have a physiological basis for reducing nausea; the main factor is hormonal.

So the correct answer is A.

• Soft, fine hair covering the body of the fetus: This is the definition of Lanugo.
• Creamy, white protective coating protecting the fetus's skin from the surrounding amniotic fluid: This is the definition of Vernix caseosa.
• First fetal movements felt during the second trimester: This is the definition of Quickening.
• White fatty material which encloses the nerve fibers on the spinal cord: This is the definition of Myelin.

So the matches are:

• Soft, fine hair covering the body of the fetus - Lanugo
• Creamy, white protective coating protecting the fetus's skin from the surrounding amniotic fluid - Vernix caseosa
• First fetal movements felt during the second trimester - Quickening
• White fatty material which encloses the nerve fibers on the spinal cord - Myelin

Answer:

Development of the fetal immune system, Growth of fetal tissue and organs, especially the brain, Production of DNA, Proper building of breast and uterine tissue to support the growing fetus
