how do farmers produce large number of banana plants in a short time?

Answers

Answer:

The banana is a perennial plant that replaces itself. Bananas do not grow from a seed but from a bulb or rhizome, and it takes 9 to 12 months from sowing a banana bulb to harvesting the fruit. The plants need rich, dark and fertile soils with steady moisture in the air and ground and good drainage.

Calcium are needed to ensure rotten root, leaf development, thereby providing high yields. Its effects are most important in ensuring high quality fruit with long term storage potential. Magnesium have a direct effect on yield, increasing the number and weight of fruit per banana bunch.

Ecosystem: includes all living things functioning together with the physical factors of their environmentBiome: is a large geographical area classified by its climate and the plant and animal life within itHabitat: includes all living things and the areas in which they live.

What is an Ecosystem?

An ecosystem may be defined as a place or an area where members of different species live together and interact with one another for the purpose of food, shelter, and space.

The Ecosystem comprises all biotic and abiotic factors of any geographical location. The Biosphere only includes the living forms where they efficiently live and play their roles. Habitat is the area where a particular type of organism is best adapted due to natural selection.

Therefore, the matching of each term with respect to its description is appropriately described above.

How would cellular respiration be impacted in the absence of photosynthesis?

Answers

Answer:

I believe it is D. Both reactants of cellular respiration would not be available

Explanation:

I do FLVS too im on the test rn :D

it was correct.

photosynthesis and cellular respiration work together to create the life cycle. without Cellular respiration we would die and without photosynthesis we would die. They are equally important without one the other could not function

have a great day

:)

Only anaerobic respiration would take place in the absence of photosynthesis, hence option B is correct.

What is the relation between cellular respiration and photosynthesis?

Oxygen and glucose are used in cellular respiration to create carbon dioxide and water. The equation for photosynthesis is the inverse of the equation for cellular respiration, further emphasizing this concept.

The cycle of cellular respiration and photosynthesis is essential for the survival of humans, animals, and plants. The term "cellular respiration" describes a chain of metabolic processes that convert glucose into water and carbon dioxide and ATP.

Therefore, in the absence of photosynthesis, there would be no glucose or oxygen for respiration, and since photosynthesis requires carbon dioxide, only anaerobic respiration would be possible.
