Answer:

Kinases would stop working too.

Explanation:

Cells work constantly to maintain homeostasis or equilibrium within themselves. One of the mechanisms used for this purpose is feedback. As mentioned in the question, kinases put phosphates on proteins, and then, phosphatases take them off. Therefore, for phosphatases to work, kinases must be working at the same pace. By inhibiting the phosphatases the number of phosphate-proteins will be too high. This can be perceived by the kinases and they will automatically stop working since there's an excess of product. That process is called feedback.

Black squirrels may increase in a certain area due to natural selection because of the ground below it being dark so the squirrels would adapt to the terrain, making them harder to see by predators.
EXAMPLE: if a light fur colored squirrel is on a dark terrain, an Owl or Large bird could easily see the color differentiation and notice that it is a small land organism (prey).
So the squirrels kin would evolve in the sense that they would have darker fur to match their inhabitance

Why do scientists usually try to work without making the animals aware that humans are present
FromTheMoon [43]

Answer:

In animal field studies, why do scientists usually try to work without making the animals aware that the humans are present? It is necessary to observe the animals without disturbing them. When a controlled experiment is not possible, why do scientists try to identify as many relevant variables as possible?

Use the scenario to answer the question.
Murljashka [212]

Answer:

fruit weight

Explanation:

In an experiment, the dependent variable is the variable that responds to the changes made to the independent variable. In other words, the dependent variable, as the name implies, is DEPENDENT on another variable called independent variable. The dependent variable is the variable that is measured or recorded by the experimenter during the experiment.

In this case where a student is studying the effect of fertilizer on fruit growth. He uses 6 tomato plants, which were given different concentrations of fertilizer (independent variable). After the experiment, the weight of the tomato fruit were measured. This means that the FRUIT WEIGHT is the dependent or responding variable.
