Cells must regulate their metabolic pathways so that they do not waste resources. What is the most common mechanism that regulat
insens350 [35]

Answer:

Feed back inhibition of glycolysis

Explanation:

Cell needs to regulate their metabolic pathways and reaction so that resources they have do not get waste and only than much product is formed which is required to be used.

Cellular respiration is most commonly regulated by the feedback inhibition of glycolysis. The most important regulatory step in the feedback inhibition of glycolysis is the phosphofructokinase reaction. This reaction is inhibited by ATP. ATP lower the affinity of enzyme for fructose-6- phosphate and inhibit the reaction thereby regulate cellular respiration.

Please help me place the cell cycle in the correct order.
kogti [31]

Answer:

Correct order is: <u>Interphase, Mitosis, Cytokinesis.</u>

Explanation:

Interphase will help grow and produce proteins for a cell. Then Mitosis will happen, which is five different stages: prophase, prometaphase, metaphase, anaphase, and telophase. Once those are all finished, Cytokinesis happens.

Hope I could help!

Why are meerkats affected by the plant population?
Radda [10]

Answer:

They largely depend on it for survival as meerkats are omnivores.

Explanation:

The combined effects of hotter and drier summers and fewer plants would threaten the persistence of the meerkat population. Since they eat plants and other living bugs that usually hang out in plant-abundant areas, their [meerkats] survival depends on the range of plants near them.

You observed many sand hill cranes on your walk. Two sand hill cranes flapped their wings and hopped up and down when you walked
Anarel [89]

Answer:

This question lacks options, the options are:

A) symbiosis

B) ecosystem

C) community

D) population

E) biosphere

The answer is D) Population

Explanation:

Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.

This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.

This observation completes what a POPULATION is all about, hence, a population was observed.
