Answer:
Biochemistry or biological chemistry, is the study of chemical processes within and relating to living organisms. A sub - discipline of both chemistry and biology, biochemistry may be divided into three fields: structural biology, enzymology and metabolism.
Biophysics is an interdisciplinary science that applies approaches and methods traditionally used in physics to study biological phenomena. Biophysics covers all scales of biological organization, from molecular to organismic and populations.
I had just learned this! The answer is D.
For women, the possibility of pregnancy begins in the ovaries. A woman is born with 1 to 2 million eggs, more than a lifetime's supply. The eggs begin dying off almost immediately and she never produces more. The average egg lives only about 24 hours, so it has to be fertilized soon for pregnancy to happen. If it doesn't get fertilized on time, it either dissolves or is absorbed by the body. When an egg is fertilized, its own genetic material and the genetic material of the sperm that got to the egg first combine to create a new cell that starts dividing rapidly. A woman isn't actually pregnant until that new bundle of cells (called the embryo) travels down the fallopian tube and attaches to the wall of the woman's uterus. The average pregnancy lasts for 38 weeks from the date you conceive (called conception). However, doctors usually date your pregnancy from the first day of the woman's last menstrual period. Using this method, a pregnancy is said to last 40 weeks, or 280 days.
