miss Akunina [59]

Answer:

The correct answer is option C. they amplify the original signal manyfold.

Explanation:

A phosphorylation cascade is a chain or sequence of the reactions that are categorized by the events where one enzyme phosphorylation another up-to phosphorylation of thousands of proteins.

The phosphorylation cascade can be experienced in involving the protein kinases as they the signal transduction of different cellular hormone messages due to their ability to amplify the original signal multiple time and make it more effective.

Thus, the correct answer is option C.

Sphinxa [80]

Options for the question have not been given. They are as follows:

type of soil

type of plants

exposure to sunlight

method for measuring the growth

Answer:

exposure to sunlight

Explanation:

A scientific experiment has an experimental group and a control group. Control group is included to omit any error in results due to the factors other than the variable factor. Experimental group is the one exposed to different levels of the variable factor.

Here, Carlo wants to determine the the effect of day length on plants' growth. The test variable here is thus the duration of sunlight. In experimental group, this duration will be changed to determine its effect. In control group it will be kept constant so that results from other factors can be excluded from the observed experimental result.

AlekseyPX

The correct answer is B. An electron orbital describes a three-dimensional space where an electron can be found 90% of the time.

Explanation:

Electrons are negatively charged particles found in atoms. These different from protons and neutrons are not located in the nucleus of the atom but orbit it. Additionally, electrons do not orbit the nucleus following a linear pattern but they have a wave-like behavior which means they move in a three-dimensional space or area known as electron orbital in which they can be found most of the time, this space of area is determined depending on energy, momentum, and other factors. Thus, an electron orbital is "a three-dimensional space where an electron can be found 90% of the time".
