Answers

The answer is (A.) Avery discovered that DNA was responsible for storing and passing information through generations.

Avery is correct. DNA serves as a storage if genetic information and passed it through generations. The DNA strands replicate and each strand serves as a template for duplication during the cell division. Therefore, DNA is the reason for biological continuity.

What do you think the following do when consumed? Protein, lipid,

Answer:

The functions of nucleic acids have to do with the storage and expression of genetic information. Deoxyribonucleic acid (DNA) encodes the information the cell needs to make proteins.

Carbs Provide Your Body With Energy

Glucose in the blood is taken up into your body's cells and used to produce a fuel molecule called adenosine triphosphate (ATP) through a series of complex processes known as cellular respiration. Cells can then use ATP to power a variety of metabolic tasks.

Functions of Lipids in the Body: Storing Energy

The excess energy from the food we eat is digested and incorporated into adipose tissue, or fatty tissue.

Protein makes up the building blocks of organs, muscles, skin, and hormones. Your body needs protein to maintain and repair tissues. Meanwhile, children need it for growth. Studies show that eating protein can also help you lose weight and belly fat while increasing your muscle mass and strength.

True or False

Answers

The given statement is False.

Radiocarbon dating cannot be used determine the age of the earth because the earth is million years old.

Radiocarbon dating can be used only for the substance that is 100-40,000 years old.

As, the earth is older than 40,000 years of age radiocarbon dating cannot be used for substances that is this much old.

Answers

A group of interdependent organisms and nonliving factors they depend on is the definition of an ecosystem. 
The answer is an ecosystem.

The ecosystem is a group of interdependent organisms and non-living factors they depend on. The group of interdependent organisms is called biotic factors, and non-living factors are abiotic factors. These two factors interact each other.A biome is a region with animals and plants with a common characteristics due to a similar climate.Habitat is an area inhabited by a particular species.Niche is the role and position of species in the environment.
