a) passive stretch, contracted, relaxed
b)passive stretch, relaxed, contracted

A student makes the statement to a colleague, "Blood plasma is essentially just a carrier for the formed cells like red blood cells and white blood cells." What would be the most accurate response to this statement?

Answers

Answer:

Plasma plays an essential role of transporting nutrients and waste.

It is a light yellow liquid, which along with water transports enzymes and salts to different parts of the body. Plasma primarily plays an essential role in transporting hormones, nutrients, and proteins to different body parts.

Apart from this, plasma also carries waste materials withdrawn from the cells and discharges it out of the body.

What connection do all living things have with each another

Answers

Answer:

they all have cells

Explanation:

each living thing has cells that help them survive and help their body work well.

Answer:

All organisms need food for the energy required to live and grow. They all excrete (get rid of) waste products, and detect changes in their surroundings and respond to them. All living organisms follow a LIFE CYCLE of growth and development, reproduction, and death. One thing all living things have in common is that all living things have cells, performing the functions necessary for an organism to survive in its environment; even the most primitive of life forms, bacteria, consists of a single cell. All living things also use energy, grow and reproduce.
