Respiration involves the breakdown of sugar. This process results in the production of energy for the cell. In order for cells to produce the MOST energy, what gas should be present?A) oxygen
B) nitrogen
C) water vapor
D) carbon dioxide

Answers

In the existence of oxygen, organisms can change over glucose into carbon dioxide. These consequences in the release of up to 38 ATP molecules' worth of energy. Thus, option A is correct.

What is the advantage of oxygen presence in cell?

Through a system called the electron transport chain (ETC), a crucial part of cellular respiration, oxygen is essential for the creation of energy.

The electron transport chain is responsible for creating the immediate cellular energy source, adenosine triphosphate.

As a result, aerobic respiration generates significantly more energy than anaerobic respiration.

Insects use oxygen for growth, reproduction, and the energy conversion of food. To get the oxygen they need, humans breathe through their mouth and nose into their lungs.

Therefore, In order for cells to produce the most energy, oxygen presence is necessary.

Answer:

A. Oxygen

Explanation:

For cellular respiration to occur, oxygen and glucose are needed, and since glucose is not a gas, oxygen is the answer.

How does nuclear energy use differ from geothermal and solar energy use?a.
Geothermal and solar energy both have a mining step, while nuclear energy does not.
b.
Geothermal and solar energy both require water, while nuclear energy does not.
c.
Geothermal and solar energy are both renewable, while nuclear energy is not.
d.
Geothermal and solar energy both generate a significant amount of waste, while nuclear energy does not.

Answers

in short the answer is c.
Geothermal energy is produced in geothermal power plants that use steam produced from reservoirs of hot water found a couple of miles or more below the Earth's surface. Because its source is the almost unlimited amount of heat generated by the Earth's core geothermal energy is a renewable source of energy. Solar energy is the energy of the sun that is converted into electricity and it is also a renewable source. On the other hand, the nuclear energy is produced as a result of nuclear reactions and is not renewable. So, nucelar energy differ from geothermal and solar beacuse geothermal and solar are renewable, and nuclear is not.

A certain species of rabbit can have either black or grey fur. The allele for black fur is dominant over the allele for grey fur. If a homozygous black rabbit is crossed with a heterozygous black rabbit, what phenotypic ratio will occur in the first generation?A.
50% black : 50% grey
B.
100% black : 0% grey
C.
75% black : 25% grey
D.
25% black : 75

Answers

Answer:

B.  100% black : 0% grey

Explanation:

If allele for black fur (BB) is dominant over grey fur (bb) and the rabbits can have either of these two colors phenotypically then a cross between a homozygous black rabbit (BB) and heterozygous black rabbit (Bb) will produce all the rabbits with black phenotype.

The cross is shown as under :

Parental         BB        x         Bb

F1                BB      BB       Bb         Bb

Genotypic ratio =>  BB : Bb = 1:1 i.e. 50% homozygous dominants & 50% heterozygous dominants.

Phenotype will be 100% black rabbits and 0% grey rabbits.

The answer is; B

If we assume that the allele for black fur is B and that for white fur is b, crossing a homozygous black rabbit with a heterozygous black rabbit, will yield the following results (indicated in the punnet square below);

Genotypically, 50% of the population will be homozygous dominant, while 50% will be heterozygous. However, phenotypically, all offspring will bear black fur because the black fur allele is dominant over the grey allele.

How does the ozone layer benefit life on Earth

Answers

Explanation:

it shields humans and other living things from ultraviolet rays

The stratospheric ozone layer absorbs ultraviolet (UV) radiation, preventing dangerous UV rays from hitting Earth's surface and harming living organisms. UV rays cannot be seen or felt, but they are very powerful and change the chemical structure of molecules.
