Answer:

(a)-True

Explanation:

Chemotrophic or chemosynthetic organisms are those capable of using reduced inorganic compounds as substrates to obtain energy and use it in respiratory metabolism. It is a faculty known as chemosynthesis. These can be chemoautotrophs or chemoheterotrophs. Like photoautotrophs (such as algae and plants), chemoautotrophs use CO2 as the main source of carbon, but unlike them, they do not use light as a source of energy but instead obtain it by oxidation of reduced inorganic compounds, such as NH3 , NO2-, H2, reduced forms of sulfur (H2S, S, S2O3-) or Fe2 +. Its cellular carbon is derived from CO2 and is assimilated through the reactions of the Calvin cycle, analogously to plants.As a result of their distinctive ability to grow in strictly mineral media, in the absence of light, these organisms are often referred to as chemolithotrophs ( lithos, rock) On the contrary, chemoheterotrophic organisms (or simply heterotrophs), such as animals and fungi, oxidize reduced organic molecules, such as glucose (via glycolysis), triglycerides (via beta oxidation) or amino acids ( oxidative deamination route) to obtain metabolic energy (ATP) and reducing power; In addition, they are unable to use CO2 as a carbon source.

During diffusion, molecules move from areas of Higher concentration to areas of Lower concentration. Diffusion does not require
Norma-Jean [14]

Answer:

The diffusion of molecules is a process that happens in our organism and the solutes move in a single direction that is always respected based on the principles of biochemistry.

Solutes always move or diffuse from compartments of higher concentration to those of lower concentration in order to equalize the amount of solute in both compartments and therefore equalize the concentrations.

Explanation:

These processes must take place between two compartments of different concentrations divided by a selective semi-permeable membrane, that is, only the solute passes and diffuses passively or actively without dragging on water or other molecules.

This process occurs in the body in those with hyper concentration of solutes in the blood in pharmacological situations.

which statement correctly describes how the amount of ofoxygen in the earth’s atmosphere has changed over time?
Kay [80]

Answer:

Based on the relative volumes of the gases in Earth’s atmosphere, nitrogen is actually more than 3 times more than oxygen. Because the troposphere is the lowest atmosphere layer, it contains 75 percent of the atmosphere’s mass.. From largest to smallest, Earth’s atmosphere composition contains nitrogen, oxygen, argon, CO 2 and trace gases.

The dominance pattern of a gene can be determined from the phenotypes of the parents and offspring. In the examples below, assum
Usimov [2.4K]

Answer:

A-complete dominant

B-codominance

C-Incomplete dominant

D-codominance

E-Incomplete dominance

Explanation:

Complete dominance- This is when a dominant Allen completely mask the effect of a recessive allele and the offspring express its phenotype E.g . A pea plant with all purple flowers and a pea plant with all white flowers produce a pea plant with all purple flowers.

Incomplete dominance- This occur when the dominant allele doesn't fully dominate over the recessive allele and the offspring shows a combination of both allele(a phenotype different from the parent)

E.g A red snapdragon and a white snapdragon produce a pink snapdragon.

Codominance- This occur when both allele express itself. The phenotype of the offspring consists of both allele example AB blood group
