       The right answer to this question is option D. Carotenoids are categorized into two major divisions: carotenes and beta carotenes

       First, let's check option A, it says that the carotenoids include red, orange and yellow pigments, that's true, we can check that on lab for example, a vegetable that can be mentioned here are carrots, it has lots of this and it's very healthy too, and remember, there isn't a single animal that can produce carotenoids, so they need to grab it from nature.

       The second option, B. says that sometimes carotenoids are sometimes called as acessory pigments, that's true too, some studies consider them acessory pigments, so, they're not alone there, there are different kinds of pigments that can be on that plant, and they're also very important for the animals. Option C refers to beta carotene as the most abundant carotene in plants, that's true too, we can also find other kinds of carotenoids on plants, but this one as it's seen in lab, is the most common one. The last one, D, isn't true, the two major divisions are: Xanthophylls and Carotenoids, beta carotenoids are a type of carotenoids, not a different group.

Nitrogen is an essential component for the growth of plants but they cannot take it
DIA [1.3K]

Answer:

Soil

Explanation:

Plants get their nitrogen from the soil. Although nitrogen is present in the air the structure of the molecule is strong and so would require large amounts of energy from the plant to break down.

The breaking down of nitrogen is a process called nitrogen fixation. Bacteria and archaea in the soil convert nitrogen into ammonia; breaking down the tough triple bond of nitrogen to be more readily absorbed by the plant.

The main problem that your central nervous system will try to solve is how to get out of this place.

<h3>B. What is the somatic nervous system probably doing?</h3>

It is releasing stimuli so that the pupil dilates and the blood goes to the muscles, to give greater physical vigor.

<h3>ç. Which part of the autonomic nervous system is likely to be active and what is it doing?</h3>

The autonomic nervous system is a part of the nervous system that functions independently of will and consists of neurons that conduct impulses from the central nervous system (brain and/or spinal cord) to the glands, smooth muscle and heart muscle.

<h3>What are the physiological responses of adrenaline binding in the sympathetic autonomic system?</h3>

Adrenaline increases the overall activity of the heart, increasing both the heart rate and the force of contraction. The heart has β1 receptors in both contractile and specialized myocardium. When turning on, a series of cardiac effects can happen.

With this information, we can conclude that the main problem that your central nervous system will try to solve is how to get out of this place.
