Plants preapare their good in their food in their root​
shutvik [7]

Answer:

In the presence of light, chlorophyll (a substance that gives the leaves a green color) releases oxygen and produces carbohydrates, which enable the plant to grow. This complex process is called photosynthesis.

Explanation:

The roots are used to take dissolved mineral elements from the soil. The root is not capable of absorbing even the smallest organic or solid element. This means that it is important that the soil contains a certain amount of water, but also microorganisms, which have the task of decomposing organic matter and releasing the mineral elements from which it is composed.

What do you think is the central question left unanswered by many origin of life theories? Reflect on
gregori [183]

<h3>The origin of life</h3>

The origin of life on planet Earth is undoubtedly a subject that intrigues all of humanity. Several hypotheses have been created to explain such an event, but to date none has been completely proven.

<h3>Answer</h3>

Many of us, however, continue to have difficulty understanding in a rational way how a small point, smaller than an atom, contained an unimaginable density and energy capable of giving rise to everything that exists today.

Bearing in mind that the biggest gap in these theories is what there is before, what there is before God, or the big bang.

With this we come to the conclusion that the theories fail in what exists before and how everything happened before the great event of creation.
