A protein kinase can phosphorylate an enzyme and activate it by
Zinaida [17]

Answer:

Signal transduction

Explanation:

A signal molecule binds to a receptor.

A conformational change in the signal-receptor complex activates an enzyme.

Second messenger molecules are released.

Protein kinases are activated.

Target proteins are phosphorylated.can be defined as the process in which a physical or chemical signal is transmitted through a cell as a series of molecular events inform of protein phosphorylation are catalyzed by protein kinase and this ultimately result into a cellular response. However, the protein that is responsible for the detection of stimuli is commonly refers to as receptors or sensor.

Leto [7]

Answer:

Diversity of the community = 2.097

Explanation:

Given:

Number of pitch pines = 134

Number of douglas firs = 24

Number of red pines = 53

Find:

Diversity of the community

Computation:

Simpson's diversity index = N(N-1)/Σn(n-1)

Particular              n n(n-1)

Pitch pine         134       17822

Douglas firs       24 552

Red pine            53  2756

Total       N=211 21130

So,

D= [211(211-1)] / 21130

D = 2.097

Diversity of the community = 2.097

Shawn will conduct a study by rolling a toy car down a ramp. He plans to set the
GalinKa [24]

Answer:

  • Independent variable: Car weight (car + block with a mass of 10 grams)
  • Dependent variable: Speed (the time the car takes to descend the ramp)

Explanation:

As you can see in the question above, Shawn wants to check the speed that a car takes when going down a ramp, related to the weight of this case, that is, he wants to know the influence of the weight that the car presents, in its speed in going down a ramp.

In this type of experiment, we can consider the weight that the car presents as the independent variable. This is because independent variables are those that influence a result within the experiment. They happen without the influence of another variable and are factors that impose changes in the analyzed system.

The dependent variable, however, is the car's speed down the ramp. This is because the dependent variables are those that need and are influenced by the independent variable, to achieve a result that can be measured and analyzed.
