Which of the following is the simplest unit of a nucleic acid

Which of the following statements is true?

fiasKO [112]

Answer: Mutations are the most fundamental way to add new genes to a gene pool.

Explanation:

Mutation refers to the process through which the normal sequence of altered. It may be either acquired or hereditary. It leads to addition of new genes to a gene pool.

The reason for not considering other statements as true are:

1. It is the hereditary mutation that are passed form parent to offspring's and acquired mutation is caused by external factors.

2. Acquired mutation are caused by external factors such as radiation.

3. Germ line mutation are important to evolution because they can be inherited.

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

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 Gastrodia kuroshimensis — 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 B. where it states that there are no chloroplasts in the plant cells.

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

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

. How does temperature change with altitude in the troposphere?

olga55 [171]

The troposphere is hotter near the Earth's surface because heat from the Earth warms this air. As the altitude increases the number of air molecules decreases, the average of their kinetic energy decreases.

Does this help?

if it does please mark me brainliest! thanks:)
