Answer:
Genetic variations that alter gene activity or protein function can introduce different traits in an organism. If a trait is advantageous and helps the individual survive and reproduce, the genetic variation is more likely to be passed to the next generation (a process known as natural selection)
Explanation:
<h2>Overproduction in Natural Selection
</h2>
Natural selection occurs in specific populations of organisms because of several factors. It begins with overproduction. Overproduction by definition, in biology, means that each generation has more offspring than can be supported by the environment. Because of this, competition takes place for limited resources. Individuals have traits that are passed down to offspring. Some of these traits give individuals an advantage when it comes to surviving to reproduce. The organisms with these traits are more likely to live and have offspring who will inherit the helpful traits.
Genes are the complex molecules
Answer is given below:
Explanation:
Unicellular organisms are single-celled organisms that contain a single cell. A single-celled organism has two types of prokaryotes, eukaryotes, examples of unicellular organisms are bacteria, protozoa, fungi, and algae multicellular organisms consisting of many cells.
Unicellular organism
- Cell division in unicellular organisms is important for reproduction. Unicellular cell division used for single-celled organisms
- Cell division in unicellular organisms is used for the reproduction of an organism.
- Mitosis is a type of cell division in a single-celled organism, such as bacteria, that is a type of asexual reproduction that produces identical copies of a cell.
Multiple cellular organisms
- The importance of cell division in multicellular organisms is the development and replacement of damaged and dead cells.
- Cell division is important for tissue growth and cell maintenance
- In multicellular organisms, more cells are produced by cell division mitosis for cell growth and repair.
