Human blood has a pH of 7.4. How do buffers in the blood affect the pH?

Biology
1 answer:
ikadub [295]3 years ago

Answer:

C

I think buffers prevents small amounts of acids and blood from coming and changing the pH of the body, because the buffers are barriers that do not let blood and acid pass through.

Hope it helps!

The cells in this part of a plant form long, vertical tubes. What is the most
3241004551 [841]

Answer:

D. The tubes allow water and nutrients to be transported throughout

the plant.

Explanation:

option D supports the description of the cells. The long , vertical tubes transport water and nutrients and are most likely xylem and phloem vessels.

option A is wrong since, chloroplasts inside the cell helps in absorbing sunlight.

option C is also wrong, because water loss is controlled by the stomata in the leaves and they are not long tubes.

option B could possibly be right but option D is better suited.

True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.
Bond [772]

Yes. True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.

The neural crest, which forms early in the development process in vertebrate embryos, is a fold on the neural plate where the neural and epidermal ectoderms converge. As an embryo grows, the neural crest produces neural crest cells (NCCs), which can differentiate into a variety of different cell types and contribute to tissues and organs.

The notochord is a temporary structure that plays a crucial role in higher animals. It secretes substances that communicate with all neighbouring tissues, telling them where they are and what will happen to them.

Therefore, True vertebrates have a true head that develops from a neural crest of cells and hard structures surrounding the notochord.
