Explain ATP in detail
Naddika [18.5K]

Answer:

Adenosine triphosphate, also known as ATP, is a molecule that carries energy within cells. It is the main energy currency of the cell, and it is an end product of the processes of photophosphorylation (adding a phosphate group to a molecule using energy from light), cellular respiration, and fermentation.

It is made up of the molecule adenosine (which itself is made up of adenine and a ribose sugar) and three phosphate groups. It is soluble in water and has a high energy content due to having two phosphoanhydride bonds connecting the three phosphate groups

 Its main function is to store energy within the cell. ... ATP hydrolysis is an exotermic reaction, releasing energy which is used by the cell.sphate groups.

vredina [299]

Answer: 1. Ways to produce meat more efficiently.

1. Livestock farming

2. Ranching

3. Grazing

2. Ways to make agriculture more sustainable

1. Practicing crop rotations.

2. Planting of cover crops.

3. Elimination and removal of soil tillage.

4. Practicing pest management.

5. Integration of livestocks and crops.

3. Organic Agriculture; this is a system of production that helps sustains the fertility of soils, ecosystems and it's people.

Advantages of organic agriculture

1. Reduction in production costs due to absence of expensive chemicals and fertilizers.

2. Farm workers are healthier.

3. Saves energy.

4. Environment protection.

4. Advantages of relying on perennial crops

1. Perennial crops have better access to groundwater due to their deep roots.

2. They require less irrigation.

3. They are more resistant to drought.

4. They help protect topsoil from erosion, runoff, and lose of nutrients which helps make the land fertile for agricultural purposes.

Explanation: meats can be produced more humanely and sustainably by practicing livestock farming and grazing.

The word organic means natural no chemicals or addictive organic farm produce are usually fertilised using animal waste and dungs.

By practicing crop rotation, the soil becomes more fertile unlike when one crop is planted continuously.

Perennial crops help repair our farmlands, unlike annaul crops. They protect the topsoil.

Use this information to answer questions 6 - 11. Your original population of
grigory [225]

Answer:

1. How did the tidal wave  affect the predicted frequencies of the alleles in the population?

No changes

2. What is the frequency of the recessive allele?

q= 0.6

Explanation:

If we assume that all individuals were equally likely to be wiped out, that means the frequency/ratio of the gene and genotype of the population will not change. The tidal wave killing 100 out of 200, so it simply makes the population become half of it used to be.  

If the population at equilibrium, we can use the Hardy-Weinberg formula to find out the expected frequency of the dominant and recessive alleles. There are 36 homozygous recessives out of 100, so the frequency of the recessive allele will be:

q^2 = 36/100

q= √36/100= 6/10= 0.6

When a person breathes, the nose and mouth take in oxygen-rich air, and they expel oxygen-poor air. Which statement explains the
kkurt [141]

Answer:

the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system

Explanation:

The human respiratory system is responsible for taking in oxygen-rich air, and they expelling oxygen-poor air. The respiratory system consists of lungs, which helps in the exchange of gases: Oxygen and carbon dioxide.

The statement ''the oxygen concentration decreases only when the air reaches the alveoli, which are the terminal branches of the respiratory system'' explains the change in oxygen concentration of the inspired air
