Insulin is an important hormone that allows the body to use glucose from food. after an individual eats a meal, glucose travels through the blood stream and reaches beta cells in the pancreas. the glucose causes the beta cells to release insulin. insulin then travels through the blood stream and attaches to insulin receptors on other cells, which allows them to take in glucose and use it for energy. what does this information best demonstrate? a. only certain cells can use glucose to produce energy. b. beta cells are not necessary for glucose to be utilized. c. a hormone is a protein that performs many functions in the body. d. cells interact with other cells for regulation and homeostasis.

The correct answer is D cells interact with other cells for regulation and homeostasis.

Explanation:

The increase in blood glucose level after intake of carbohydrate rich meal,generate a signal for the release of peptide hormone insulin from the beta cells of pancreas.

   The released glucose then travels through blood stream and interacts with insulin receptors on the target cells such as liver,muscle,heart cells,brain cells etc and helps these organs to uptake glucose from blood stream thus reducing the blood sugar label.

  Thus one cell interact with another cell for regulation and homeostasis.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.

all these collisions do one thing, and that thing is explained in the last option. when dusst, rocks and ice collide, they harden and form giant layers of rocks or hard ice.

d)   to harden materials to form different parts of earth’s layers
