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.

Explanation:

The largest constituent of the blood that comprises 55 percent of its entire constituents is the plasma. 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Apart from this, plasma also carries waste materials withdrawn from the cells and discharges it out of the body.

An earthworm receives support and shape from its fluid-filled cavity. It has _____. an endoskeleton an exoskeleton a hydroskeleton no skeleton

Answers

No skeleton, it may look like it but there isn't one. Because when you squish the worm there is nothing but flesh and blood. However there is a certain type of worm that has a skeleton just not an earthworm. (I don't know what the name is of the worm that has a skeleton.)
Hope this helps:)

a work has no skeleton, which is why it can bend in all different directions, but the main reason i know this, is cause if you pinch a work between your thumb and forefinger, it will break, and there is nothing on the inside of the worm that indicates there is a skeleton

Glucose provides energy for cells. Different cells have different mechanisms for glucose intake. Intestinal cells contain proteins that transport glucose against its concentration gradient. These proteins couple the movement of glucose to the movement of sodium down its concentration gradient. Red blood cells have transporter proteins embedded in their membranes. When bound by a glucose molecule, these proteins change shape and allow glucose to move down its concentration gradient into the cell. Based on this information, what type of transport is used for glucose in blood and intestinal cells?
