Answer:

Plants too are the living organisms of the ecosystem. They too respond to the external environmental stimuli.
Phototropism is the best example for it. All of us know that for plants to grow light is necessary . Hence all plants respond to the changes in the environment , and respond to it by growing their stems, roots, or leaves toward the direction of stimulus or away from the stimulus.

Which correctly describes molecules “a” in this diagram?

cupoosta [38]

Answer:

A. Adenosine triphosphate

Explanation:

Molecule "a" shows the structure of ATP which stands for Adenosine triphosphate. ATP provides the energy that cells need to conduct the different processes within it.

Adenosine is made up adenine and ribose, which is attached to 3 phosphate groups, which you see there as the three circles with a P in it. These phosphate groups hold oxygen in them and they hold a lot of potential energy because of their negative charges.

<em>NOTE: If you take out one of these phosphate groups, you'll get the structure of molecule 'b'. So instead of "tri" which means three, you'll have a diphosphate because 2 will be left. </em>

Attached you'll see a labeled ATP molecule.

Rank the following gases in order of their concentration in Earth’s atmosphere from smallest to greatest.Oxygen, Carbon Dioxide,

grigory [225]

Answer:

Hydrogen

Carbon Dioxide

Water Vapor (assuming the air is not dry)

Oxygen

Nitrogen

Explanation:

We have to make the distinction between dry air and humid-air

Oxygen, Carbon Dioxide, Water Vapor, Nitrogen, Hydrogen

Hydrogen 0.000055%

Carbon Dioxide 0.413%

Oxygen 20.946%

Nitrogen 78.084%

The case of water vapor is quite variable and can increase up to 3% in some cases (lowering the participation of the other gases) but, it is near zero when the air is dry. Thus it their participation will be above Carbon Dioxide
