Answer:

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less.

Explanation:

A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less. Several factors affect the rate at which enzymatic reactions proceed include post translational modifications, substrate concentration, cofactors, temperature, pH, locations. The shape and structure of the enzyme will change as the pH value of the reaction medium changes.

Vlad [161]

Answer:

The hours are the independent variable.
The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .
The domain is 0 to 30
The range is 0 to 330

Explanation:

The hours are the independent variable and should be plotted on the x-axis .

The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) and should be plotted on the y-axis

---------------

Let +W+ = wages/wk earned

Let +h+ = hours/wk worked

The equation is:

+W+=+11h+

The domain is 0 to 30

( no hrs worked to 30 hrs worked )

The range is 0 to 330

( no wages eared to +11%2A30+=+330+ earned )

Arte-miy333 [17]

Answer:

The form of cell to cell signalling that is been used is ENDOCRINE.

Explanation:

There are four ways by which cell signalling occur in the body, these are: endocrine, paracrine, autocrine and direct signalling.

Endocrine signalling is the biochemical process by which hormone secreting glands release hormones into the blood streams and that hormone has effects on target organs that are located far away from it. Endocrine hormones are usually stable and their effects usually last for long time.
