Answer: B). Photosynthesis

Explanation:

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.

The answer is photosynthesis.

<span>Photosynthesis occurs in the leaves of green plants. During photosynthesis, carbon dioxide and water are converted into using the energy of sunlight to glucose and oxygen. After great evolution of plants, the photosynthetic rate was increased. More plants mean more oxygen produced in the process of photosynthesis. Thus, photosynthesis </span><span> is most responsible for the increase in early Earth’s atmospheric oxygen levels.</span>

Which is an SI derived unit measurement?<br><br>0.56 kg<br>01.10 m<br>2730K<br>02.5 N​
balandron [24]

Answer:

02.5 N​

Explanation:

02.5 N​ is a derived unit of measurement.

A derived unit is one that is obtained by combining two or more fundamental units.

                    Force = mass x acceleration

                The unit of mass = kg

                                   acceleration = m/s²

Combining the two;          kg x m/s²  = kgms²

          1N = 1  kgms²

kg, m, k and N are fundamental particles

Consider three molecules, named X, Y, and Z. When added to a beaker of water they undergo spontaneous reactions. When X is added
harina [27]

Both X and Z will increase in order.

Option D.

<h3><u>Explanation:</u></h3>

Here in the question we can see that all the three compounds X Y and Z are in equilibrium as they are put in a water beaker containing water. This phenomenon is Called chemical equilibrium when the substances that are isomers to each other actually forms in water and their relative concentration remains in a particular ratio according to their stability.

Here in the question, the solution contains X Y and Z in equilibrium. But if more Y is added in the solution, firstly the equilibrium constant for X and Y will get disrupted because X will get low in amount with respect to Y. So some Y will get converted to X. Similarly, when Z will also face the same problem and some Y will get converted to Z. Hence the amounts of both X and Y will increase along with Y.

Answer:

Sympathetic Nervous System.

Explanation:

Sympathetic nervous system is one of the parts of Autonomic nervous system and the other part is Parasympathetic nervous system.

As a whole the autonomic nervous system controls the unconscious responses of our body.

The main function of the Sympathetic nervous system is to stimulate the 3F response of the body. Here 3F refers to Fight, Flight and Freeze. Adrenal gland is stimulated by this system which secretes adrenaline. Due to the effect of adrenaline heart neat increases, blood pressure increases, pupils dilate, sweat glands are activated, peristalsis in the gut is inhibited, and kidney secretion increases.

How are convection currents produced in the air?
nika2105 [10]
Convection currents are caused by the colliding of cold and warm air. At night, air above water is warm and air above land is cold. The opposite is true in daytime. When the warm air hits the cold air, which is more dense, it is pushed upward. Then it travels laterally until it cools. It comes back down and pushes up the former cold air, which is now warm. This repeats many times.
