Centrioles ensures appropriate cell growth and rates of division.

What are Centrioles?

Small clusters of microtubules known as centrioles are positioned precisely within the cell nucleus. Because these organelles are only visible while they are assisting the cell during the phases of cell division, they are not clearly apparent within the cell (mitosis and meiosis).

Centrioles are composed of nine clusters of microtubules. When the cell is dividing, they are typically found in pairs and move towards the opposite pole ends of the nucleus. Centrioles duplicate during the Interphase of cell division.

As we know the flow energy from trophic levels is only 10% of the net energy transferred from one trophic level to another. So, if a snail has 358 calories, then the plant stores energy of 3580 kilocalories or about 3500 calories.

Plants are the main producers in trophic levels. This means that plants produce and synthesize their food. Snails at the trophic level are the main consumers. Hence, slugs are at the second trophic level.

We know that only 10% of the net energy is transferred from one tropic level to another. So, if the amount of energy possessed by a snail is 358 kilocalories.

Answer:  They form dynamic contacts with each other to exchange molecules and regulate organelle division and positioning in coordination with the cytoskeleton

Explanation: I hope this helps!!!!

Organelles that are membrane-bound create dynamic interactions with one another to exchange molecules and control organelle placement and division in concert with the cytoskeleton.

It is generally known that mitochondrial-cytoskeletal interactions play a part in mitochondrial mobility. Recent research suggests that these interactions control the equilibrium of mitochondrial fission/fusion, mitochondrial turnover, and mitochondrial inheritance during cell division.

The cytoskeleton's protein filaments act as "tracks," allowing organelles to move about the cell.

G protein would constantly be in motion. G proteins are a family of proteins that serve as molecular switches within cells, they are engaged in the transfer of signals from the outside of the cell to its interior.

G proteins are trimers made up of three distinct subunits that activate adenylyl cyclase. Alpha, beta, and gamma subunits are the names of these. Gs is the name of the nucleotide-binding site on the alpha subunit. Adenylyl cyclase is activated when GTP binds to Gs, activating it in turn. When GDP binds to the nucleotide-binding site of G-protein, it becomes inactive.

When a signalling molecule like adrenaline binds, it makes it easier for GTP to replace the bound GDP and change the Gs into its active form. The beta and gamma Gs subunits separate from the alpha subunit as Gs is activated. Adenylyl cyclase is then activated by the Gs after it has bound GTP and its alpha subunit.
