Answer:

(B) Energy released from the chemical reaction is used to directly phosphorylate ADP.

(D) Energy released from the chemical reaction is used to directly reduce NAD+

<h2>Explanation:- </h2>

(1) Group of cell that work together as one to perform a single function is termed as Tissue . Then the group of tissue combine to form organs and further they combine to organ systems and further they combine to form organ system .

(2) They are unicellular green algae which belongs to family Volvocaceae of the Plantae Kingdom

(3) Hypothesis is the assumption which are taken on the behalf of the observation on small <u>scale</u> . They can be correct or incorrect depends on the number of observation and Hypothesis.

(4) Viruses are included in any of the kingdom because they are on the intermediate line of living and non living as they show properties of non living outside the host and properties of living inside the host

Two-component regulatory systems rely on a balance of phosphorylation and dephosphorylation of sensor kinases and response regul
otez555 [7]

Answer:

The correct answer is the first statement.

Explanation:

A fundamental stimulus-response coupling mechanism that helps various species to react and sense different modifications taking place in various distinct environmental circumstances is known as a two-component regulatory system. Though this system is found in almost all the domains of life, however, it is generally witnessed in species like bacteria, mainly in the Gram-negative and cyanobacteria.  

In case, if the response regulator turns completely phosphorylated because of the absence of phosphatase activity, the cell would become insensitive towards the environmental stimulus. This generally happens as the cell will lose its tendency to sustain the response cycle because of the imbalance in the dephosphorylation and phosphorylation system that helps in sustaining the response of the cell towards a specific environmental stimulus.
