8 0

Answer:

True.

Explanation:

Alveoli are the microscopic structure present deep inside the lungs. Alveoli acts as a basic unit of ventilation. Alveoli are present in the lungs of mammals only.

Alveoli are hollow sac like structures when viewed under the microscope. Alveoli are the main site of the gas exchanges in the mammals. The alveoli are covered by the epithelial layers.

Thus, the correct answer is option (a).

Which substance is considered to be a proven ergogenic aid that increases athletic performance?
fenix001 [56]

Out of the following given choices;

<span>A.      </span>Salt tablets

<span>B.      </span>Bee pollen

<span>C.      </span>Carnitine

<span>D.      </span>Coenzyme Q10

<span>E.       </span>None of the above  

The answer is D. (none of the above). These elements are found  naturally in nature and in our bodies. Coenzyme Q-10 and carnitine are found naturally in our bodies while bee pollen and salt are found naturally in our environments. Therefore, it is implausible to consider them ergogenic substances

The sodium amytal test involves the injection of a small amount of sodium amytal into the carotid artery on one side of the neck
romanna [79]

The sodium amytal test involves the injection of a small amount of sodium amytal into the carotid artery on one side of the neck. This injection anesthetizes the hemisphere on that side for a few minutes.

A method that involves injecting a small amount of a barbiturate into the carotid artery on one side of the head to assess hemispheric functions, usually memory and language. The cerebral hemisphere that was injected selectively becomes impaired for 10 to 15 minutes during this operation.

Various cognitive tests are given while each hemisphere is seperately anaesthetized; deficiencies on these tasks imply that these functions are represented in the anaesthetized hemisphere. Prior to a temporal lobectomy, the Wada test may be utilised in cases with severe and uncontrollable epilepsy. Also known as the Wada technique, intracarotid sodium Amytal test (ISA), Wada dominance test, and intracarotid amobarbital procedure.

Which is an important difference between light-dependent (L-D) and light-independent (L-IND) reactions in photosynthesis? The L-
Yuliya22 [10]

Answer;

The L-D reactions require light energy and water, and the L-IND reactions require ATP, NADPH and CO2.

Explanation;

-Photosynthesis is the process by which green plants use light energy from the sun, water and carbon dioxide to make organic molecules, such as simple sugars.

-The process takes place in two phases; light dependent stage and light independent stage.

-During light dependent stage light energy is used to break down water molecules into hydrogen ions and oxygen atoms.

-Light independent reactions uses CO2 and the ATP and NADPH from light dependent reactions to produce sugar/ glucose. ATP is used to provide the energy for sugar synthesis and NADPH is used for electrons in the reduction of Carbon Dioxide into sugar.
