The mass of the atom is contained mainly in the nucleus itself. The nucleus is composed of a number of protons and neutrons which are positively charged and neutrally charged sub particle components. The nucleus are surrounded by electrons.

The mass of an atom is contained primarily in its NUCLEUS.
An atom is made up of three sub particles, which are proton, neutrons and electrons. The proton and the neutrons are located in the nucleus of the atom while the electron are located outside the nucleus where they move about in continuous motion around the nucleus. The proton and the neutrons, which are located in the nucleus have the same relative mass of 1, which has been estimated to be about 2,000 times bigger than that of the electron, which has a relative mass of 0.0005. This shows that, the mass of an atom is located primarily in its nucleus. <span />

Explain why there is usually more water vapor in expired air then inspired air

satela [25.4K]

Answer:

The result is that the exhaled air contains less oxygen and more carbon dioxide than the inhaled air. ... In fact, exhaled air is completely saturated with water – it contains the maximum amount of moisture, and is therefore has a relative humidity of 100%. We lose water as we breathe!

Each member of the human hemoglobin gene family, which consists of seven genes arranged in two clusters on different chromosomes

Kay [80]

Answer:

B. False

Explanation:

Orthologs are genes that find their origin in vertical descent,, paralogous on the other hand, are genes that are related via duplication events. <em>In the case of human hemoglobin, their genes originated by duplication from an common ancestral globin gen, therefore they are paralogous.</em>

In C3 plants the conservation of water promotes_______.a. photorespiration. b. a shift to C4.c. photosynthesis.d. the opening of

ankoles [38]

Answer:

A) photorespiration.

Explanation:

Photorespiration is the harmful metabolic process which takes place when the concentration of oxygen in the leaf increases compared to carbon dioxide.

The RUBISCO enzyme which usually binds the carbon dioxide now binds the oxygen and form the phosphoglycolate and 3 phosphoglycerate. The phosphoglycolate is lost through the Calvin cycle as Carbon dioxide molecule. This loss proves harmful to the plants.

The photorespiration occurs when the plant faces high temperature therefore n order to prevent water loss the stomata gets closed. This result in the binding of the oxygen to the RUBISCO and thus photorespiration begins.

Thus, Option-A is correct.
