Answer:
Sarah's skeletal muscles and blood vessels
Explanation:
Sarah noticed his hot red face after physical activity. This was because when her body temperature began to rise, the body sweated and dilated the blood vessels in her skin to reduce this temperature. Because oxygenated blood runs down the surface of the skin, which helps radiate heat and prevent overheating, the face turns red and gets a little warm from blood circulation. This whole process was done by Sarah's skeletal muscles and blood vessels as a homeostatic response that sought to establish a balance in the girl's body.
Answer:
The process by which the egg cell (i.e., structure labeled B) is released from the ovary (i.e., structure labeled A) is known as ovulation
Explanation:
The egg cell, also known as an ovum, is the female gamete (i.e., the female reproductive sex cell), which is produced in the ovaries. The ovaries are the female gonads that contain many follicles, and each of them contains a single oocyte (immature egg cell). Ovulation occurs when a mature egg is released from the ovary during the menstrual cycle. During this process, the ovum moves to the fallopian tube where it can be fertilized by a sperm cell (male reproductive cell or male gamete). If fertilization occurs, the ovum moves to get implanted in the uterus and develop an embryo.
Sodium ions help control blood flow, blood volume, osmotic balance, and pH.
