PLZZZZZZ HELPPPP Draw a sketch of your completed DNA model. Label each material and the part of the DNA molecule it represents.Answer:

Answers

Answer 1
Answer:

Answer:

DNA - Deoxyribonucleic acid, a macro molecule which has all the hereditary data or information in many living beings.

Function- DNA plays an important role in the production of proteins, along with the metabolism, and reproduction of the cells.

  • Components- Deoxyribose sugar,
  • A phosphate,
  • A nitrogenous base.( adenine, guanine, thymine and cytosine)

Explanation:

Structure of DNA:

  • The image is a simplified representation of a short DNA molecule, with deoxyribose sugar molecules in orange, linked to phosphate molecules through a special type of covalent linkage called the phosphodiester bond.
  • Each nitrogenous base is represented by a different color – thymine in purple, adenine in green, cytosine in red and guanine in blue.
  • The bases from each strand form hydrogen bonds with one another, stabilizing the double-stranded structure.

The amount of inertia an object has depends on its speed? True or false

Answers

Answer:

False

Explanation:

Inertia depends on the objects mass. It states that inertia is a property of matter, therefore it continues in its state of rest or in uniform motion, unless it is acted upon by some external force. Inertia depends on the mass only.

All of the living and nonliving things that interact in a particular area make up a _____

Answers

All of the living and nonliving things that interact in a particular area make up a ecosystem.

What are living things?

Living things are defined as which are made up of a cell. They form and use energy to survive. A special ability to reproduce, grow, metabolize, able to respond to stimuli, adapt to the environment, move and able to respire.

For example, relationship between lion and sheep in the ecosystem for its survival, the lion prey the sheep. And each relationship in the ecosystem has an effect on other creatures and plants living in the same area.

all of the living things in a particular area: community

Explanation:

Why does sexual reproduction result in more genetic diversity than asexual reproduction? A.Traits from two parents are combined.

B.More organisms reproduce this way.

C.Offspring grow in different environments.

D. Offspring come from identical parents.

Answers

Answer:

A. Traits from two parents are combined

Explanation:

Each time you have a sexual reproduction the offspring get a mixture of both the parents genes, making the offspring's genes unique. However since the asexual reproduction would produce an offspring with an identical genes to one parent, the genes are the same.

In other word the asexual reproduction does not have any diversity, and the sexual reproduction does because it is a mixture of two parents genes.
Answer: A

By diversifying offspring you enhance the ability to pass on desirable traits.
