What are capillaries?
Select one:
a.
blood cells that fight infection
b.
vessels through which nutrient and gas exchange take place
c.
chambers of the heart that pump blood throughout the body
d.
the liquid part of the blood that transports hormones
Answers
b. Capillaries are vessels through which nutrient and gas exchange take place.
Capillaries are the smallest blood vessels in the body and are responsible for facilitating the exchange of nutrients, gases, and waste products between the bloodstream and surrounding tissues. They connect the arterioles (small branches of arteries) and venules (small branches of veins).
Capillaries have thin and permeable walls, consisting of a single layer of endothelial cells. This structure allows for the exchange of substances between the blood and surrounding tissues. Oxygen and nutrients diffuse out of the capillaries into the tissues, while carbon dioxide and waste products from cellular metabolism diffuse into the capillaries to be carried away.
The extensive network of capillaries ensures that every cell in the body is located in close proximity to a capillary, allowing for efficient exchange of substances. This exchange includes the delivery of oxygen and nutrients to the cells, as well as the removal of carbon dioxide and waste products.
While blood cells, such as red blood cells and white blood cells, are present in the capillaries, they are not the defining characteristic of capillaries. Instead, capillaries are primarily associated with facilitating the exchange of substances between the bloodstream and the surrounding tissues.
Therefore, option b is the correct answer as it accurately describes the role of capillaries in facilitating nutrient and gas exchange.

Which two major biological processes involved in the oxygen cycle are represented in the diagram? A. respiration and precipitation B. photosynthesis and evaporation C. photosynthesis and respiration D. evaporation and precipitation
Answers
Answer:
(c)
Explanation:
The two major biological processes involved in the oxygen cycle are Photosynthesis and Respiration.
Because of this, the byproducts of one system are the reactants in the other, which is how photosynthesis and cellular respiration interact. Oxygen and glucose are produced during photosynthesis by using the energy from sunshine, water, and carbon dioxide. The production of carbon dioxide and water during cellular respiration needs glucose and oxygen. The expression for photosynthesis is the inverse of the equation for cellular respiration, which serves as more evidence for this argument.What is Oxygen cycle?The layer of gases present above the surface of the world is called the atmosphere. A biosphere is comprised of all of Earth's ecosystems. The biggest oxygen reserve is located in the lithosphere, the solid outer layer of the globe that also includes the crust. The oxygen cycle is crucial to the continuation of life on Earth, together with the carbon and nitrogen cycles.This biogeochemical cycle shows how oxygen moves throughout the atmosphere, ecosystem, biosphere, and lithosphere. The carbon cycle is linked to the oxygen cycle.Mainly responsible for preserving the atmosphere's oxygen content is the oxygen cycle. The complete process can be summed up as follows: the oxygen cycle starts with photosynthesis, which takes place in the presence of sunlight, produces oxygen back into the atmosphere, allowing people and other animals to breathe in oxygen and exhale carbon dioxide, and then links back to the plants. This demonstrates the independence and connection of the oxygen and carbon cycles as well.To learn more about Oxygen cycle, refer to:

How did the mutation change the hemoglobin protein?
ASAP
Answers
Answer: A mutation Changes by its mistake in the DNA which results in the wrong amino acid being incorporated into a protein because of change, that single DNA sequence change, results in a different amino acid codon which the ribosome recognizes.
Explanation:
A mutation changes the instructions of a gene, which can also change the protein. Sometimes this change makes it so the protein can't do its job as well. And this is what happens with sickle cell anemia. A mutation in the hemoglobin gene changes the hemoglobin protein in a way that causes sickle cell anemia.

A patient has swollen feet, ankles, and legs, and has pain in his lower back. Tests show the level of urea, a waste product, in the patient's blood has suddenly risen. Which body system is most likely not functioning properly?
A.
Nervous
B.
Excretory
C.
Digestive
D.
Reproductive
Answers
The body system that is most likely not functioning properly is excretory system. The correct option is B.
What is excretory system?The excretory system is a detached biological mechanism that removes excess, unneeded materials from an organism's body fluids to help maintain internal chemical homeostasis as well as prevent body damage.
The excretory system's function is to remove waste from the body. Water, CO2, nitrogen, salts, and heat are among the wastes. Metabolism refers to the process by which the body converts food into energy.
The primary function of the kidneys is to eliminate excess water and wastes from the bloodstream through the production of urine, a liquid waste.
As the patient has swollen feet, ankles and legs and having urea level boosted in blood, it means his excretory system has some problems.
Thus, the correct option is B.
