1 answer:

3 0

1) C. Gymnosperms are mostly adapted for wind pollination; angiosperms are mostly adapted for animal pollination. This is the best answer, because the others had the two types reversed. Gymnos have "naked" seeded cones, whereas Angios have seeds protected by fruit. Therefore the Angios relies on animals to eat the fruit and to pollinate, whereas Gymnos relied on wind to pollinate the ground. Gymnos came first on Earth and Angios developed later.

2) C. Cuticle. This is a waxy coating helping to keep water in. The main water losses are via stomata.

3) C. Stomata

4) B. Nonvascular

5) B. Gravity

These answers were explained in the questions that I just answered before. So refer to those for explanations.

VMariaS [17]

Taking a measure of someones blood glucose level before they eat in the morning is a measure of fasting blood glucose. A normal measure of fasting blood glucose is 3.8 to 5.5 mmol. If the value were higher, say 5.8 mmol then the patient would be described as being pre-diabetic. Since the value is the highest in the range of being normal she should be monitored for pre- diabetes.

Which lipoprotein transports dietary fat to the cells in your body?

Anvisha [2.4K]

Chylomicron is a lipoprotein that transports dietary fat to the cells in the body.

Chylomicrons are extremely low-density, large lipoproteins that transport dietary lipids from the intestine to tissues.

Chylomicrons include triglycerides and other lipids absorbed by enterocytes to incorporate them into the body.

By being activated by the Apolipoprotein CII Protein, the body ensures that lipoprotein lipase only acts on mature lipoproteins.

This enzyme hydrolyzes the triglycerides that form the monolayer of the chylomicron, allowing the uptake of lipids by the muscle or connective cells that will use those lipids.

Therefore, we can conclude that chylomicrons are responsible for mobilizing the lipids that are ingested in the diet by the body.
