Marianna [84]3 years ago
6 0

Answer:

Euglenoids lack a Cell wall

Explanation:

Euglena is a unicellular photosynthetic protista that can be found in both salt water and fresh water. As Euglena has chloroplasts they can produce their own food through photosynthesis. For their movement in water they have specialized structure called flagella. Near Flagella another pigmented spot exist called eyespot. Eyespot helps euglena to detect sunlight. Euglenoids lack cell wall so they have more flexibility for movement.

dangina [55]

The question is incomplete. The complete question is as follows:

Which of the following is not true regarding fenestrated capillaries?

A) Fenestrated capillaries in endocrine organs allow hormones rapid entry into the blood.

B) Fenestrated capillaries in the small intestine receive nutrients from digested food.

C) Fenestrated capillaries are essential for filtration of blood plasma in the kidney.

D) Fenestrated capillaries form the blood-brain barrier.

Answer:

Fenestrated capillaries form the blood-brain barrier.

Explanation:

The fenesterated capillaries are small fine thin capillaries that helps in the exchange of substances. These capillaries are mainly found in the kidney, small intestine and glands.

The fenestrted capillaries allow the exchnage of hormone in the blood and in the kidney for the filtration. The nutrients can be easily exchanged by the capillaries present in the small intestine. The blood brain barrier function is not performed by the fenesterated capillaries. They allows the rapid exchange function and not as the barrier.

Thus, the correct answer is option (D).

She became increasingly aware of the harmful facts of insecticide DDT on the environment. This compelled her to write her most famous work Silent Spring and defending herself against attacks from commercial interests.

The book also played an influential part in persuading governments to ban or heavily restrict the use of DDT and similar chemicals that persist in the environment.
