3. The blood would not clot in case of an injury.
4. Blood supplies essential substances and nutrients.
Explanation: 1. White blood cells are able to recognize viruses and/or infectious germs, which is how they fight off disease/sickness. It is also why we have vaccines. Vaccines put either dead or weakened parts of a germ into your body. Then, the white blood cells recognize it and fight it off the next time it enters your body.
2. They contain hemoglobin, a red protein that combines with oxygen. They have no nucleus so they can contain more of the hemoglobin. they are small and flexible so that they can fit through narrow blood vessels.
3. This will lead to excess blood loss and can even lead to the death.
4. Such as as sugar, oxygen, and hormones to our cells. It also carries waste away from the cells, this waste is eventually flushed out of the body in urine, feces, sweat, and lungs.

functions of bowman's capsule and materials absorbed in the bowman's capsule
Answer: The structural and functional unit of the kidney is called a nephron. It consists of two main parts viz. the glomerulus and the tubular system. The glomerulus is composed of Bowman’s capsule and a tuft of leaky blood vessels encapsulated by the Bowman’s capsule.
Glomerulus capsule is a tuft of capillaries that are found inside the capsule of Bowman. Bowman’s capsule is a sac-like organ that is present at the nephron’s tabular end, encapsulating glomerulus in it.
The primary purpose of the glomerulus is filtration. The leaky vessels filter into the glomerulus almost all the water, electrolytes, small proteins, nutrients such as sugar etc and excretory products such as urea, etc.

Describe how scientists make inferences on whether water is polluted or not
Answer: Water that's safe to drink should ideally be clear with no odor or funny taste. One way to tell if water is contaminated is to look for turbidity, or cloudiness. While cloudy water isn't necessarily dangerous to your health, it could signal the presence of unsafe pathogens or chemicals.

Drinkable water should ideally be transparent and taste and smell normal. Look for turbidity, or cloudiness, as one indicator that water is contaminated.
What is drinkable water?Surface water and groundwater are the two sources of potable water, also referred to as drinking water. The level of treatment applied to this water satisfies both state and federal standards for potable water.
The indirect potable reuse (IPR) and direct potable reuse (DPR) processes are the two basic ways to turn wastewater into potable water (DPR).
Foggy water may not always be harmful to your health, it may indicate the presence of germs or chemicals that are toxic.

what hormone do the c-cells secrete, and what is the function of this hormone?
Answer:
Calcitonin is one of those critical hormones. Calcitonin is a hormone that the C-cells in the thyroid gland produce and release. It opposes the action of the parathyroid hormone, helping to regulate the blood's calcium and phosphate levels. How does calcitonin work?
The hormone that the c-cell secrete is calcitonin. The function of calcitonin is a hormone that regulates the amount of calcium in your blood by decreasing it.
What are hormones?The important hormone is calcitonin. Calcitonin is a hormone produced and released by the thyroid gland's C-cells. It works in opposition to the activity of the parathyroid hormone, assisting in the regulation of calcium and phosphate levels in the blood.
Calcitonin is a hormone produced by the thyroid gland, which is a tiny, butterfly-shaped gland found near the throat. Calcitonin regulates how the body uses calcium.
Calcitonin is a cancer marker. Tumor markers are substances produced in the body by cancer cells or normal cells in response to cancer.
Thus, calcitonin is the hormone secreted by c-cells. Calcitonin is a hormone that controls the quantity of calcium in your blood by reducing it.
