Answer:

D. Water is the most abundant atom in Earth’s atmosphere.

Explanation:

An atom can be defined as the smallest particle of an element (e.g., oxygen, hydrogen, etc). Water is a molecule (H2O) because its atoms are connected by molecular bonds (i.e., water is not an atom). Water is the most abundant molecule on the Earth's surface which covers more than 70 percent of the world's surface. A water molecule contains one oxygen (O) and two hydrogen (H2) atoms which are connected by covalent bonds. Water is also a compound known as a diatomic molecule, i.e., a molecule composed of two atoms of the same type.

A scientist discovers a new plant. After investigating its properties, the scientist concludes that the plant does

gayaneshka [121]

non-photosynthetic plants are not common in nature, they do not have a green color, to be able to answer the question we must know that .......

<h3>General characteristics of plants</h3>

Plants are classified as autotrophic organisms, since the large one is capable of photosynthesis. With the exception of plants, some achlor species being observed, therefore, not achlorizing plants.

<h3>Chloroplast</h3>

Chloroplast, a structure within the cells of plants and green algae that is the site of photosynthesis, the process by which light energy is converted to chemical energy, resulting in the production of oxygen and energy-rich organic compounds.

<h3>It happened in real life</h3>

The newly discovered plant — named <em>Gastrodia kuroshimensis </em>— occurs in the dark understory of forests, where little light penetrates. So instead of using sunlight or photosynthesis to generate nutrients, the plant parasitizes the fungi in the forest soil for its daily dose of nutrition.

With this information we can say that the correct alternative is<u> B</u>. where it states that there are no chloroplasts in the plant cells.

B. There are no chloroplasts in the plant's cells.

<u>These </u><u>plants</u><u> that do </u><u>not photosynthesize</u><u> do not have the green </u><u>pigment</u><u>, what gives the </u><u>plants</u><u> their </u><u>green color</u><u> is the </u><u>chlorophyll</u><u> that is in the </u><u>chloroplast.</u>

Moss and lichen arrive by birds to barren lava field.
Soil is created.
Fountain grass grows.
Monkeypod trees grow.

<h3>What is ecological succession?</h3>

Ecological succession refers to the series of changes that occur in a habitat gradually with new species replacing existing species or a barren habitat until the environment becomes more complex.

A lava field is a barren field where there are no species

The ecological succession that occurs in a lava field is as follows:

Moss and lichen arrive by birds to barren lava field; Soil is created; Fountain grass grows; Monkeypod trees grow.

Thymine dimers can be repaired by Photoreactivation Repair or Nucleotide Excision Repair. - true or false?

Aleksandr-060686 [28]

Answer:True

Explanation:Basically thymine diamers are mismatched pairs (thymine binds with another thymine instead of binding with adenine) and may lead to unwanted results so the mismatching can be repaired by using two methods which are as follows :

1-the PRE enzyme activated by blue light breaks the thymine diamer and some of the surrounding bonds the strand is cut and DNA polymerase then restores the normal base pairing

2-UVR system breaks dimer creating a gap when a gap is created and the molecules appear unpaired it is filled by proof readers hence restoring normal base pairing.

What is the best example of how the nervous system maintains homeostasis?

Blizzard [7]

I'm not sure if it's the "best" example but.

If your blood tempature is low, the hypothalamus will issues reflex commands that make your body shiver. If you are hot, you will sweat is the opposite of this.

Another example is, if your blood contains pyrokines then you might have an infection so you begin to run a fever as your body's way to kill the pathogen at the direction of the hypothalamus.

Hope these examples help!
