Answer:
Charles Robert Darwin was a British naturalist and biologist known for his theory of evolution and his understanding of the process of natural selection
Explanation:
2. <u>Some of these variations are passed on to offspring;</u>
- As the genetic changes may occur due to mutations in the genes.
- As these changes do not occur in days or months but they occur after hundred and thousands of years.
- The off springs are distinct from their ancestors. This results in the formation of new species. Gradual modification of the existing species leading to the formation of new species is known as speciation.
4<u>.Individuals vary in their ability to survive and reproduce</u>;
- Those with the most favorable adaptations are more likely to survive and reproduce.
- Individual variation (usually through mutation) may introduce traits or abilities that enable that individual to survive in order to reproduce. Usually these are tiny incremental changes that accumulate over centuries or millennia.
<u>Note:</u><em> However there are certain drawbacks of Darwinism even such as it failed to explain the basis of variation and the mode of transmission of characters.

Answer:
the process that would make them go as dark or light would be because they and blend in better to no the eaten it is called "latrell Selection" so in the Beach mice would stay light because they look like sand but if they were dark they would be easy to see that is why they are not there same thing for the forest but the other way around
if the forest changed to more sandy it would let lighter mice live there to but the dark mice would still live because it is not all sand i like it would be equal amount of dark and light mice because they would both have there spot to hide and just as vulnerable if the switched spots

The part of the nerve cell that is specially constructed to transmit a message from one cell to another nerve cell is axon.
<h3>What is a nerve cell?</h3>
Nerve cell is a cell of the nervous system which conducts nerve impulses, also referred to as a neuron. It is the basic unit of communication in the nervous system.
The nerve cell is a type of cell that receives and sends messages from the body to the brain and back to the body. The messages are sent by a weak electrical current.
The nerve cell is made up of three main parts as follows:
- Cell body
- The dendrites
- The axon
The cell body, also called the soma of the neuron contains the cell’s nucleus, which controls the activities of the cell.
Dendrites are extensions that branch off the cell body. They receive chemical signals from other neurons, which they convert to electrical impulses and transmit to the cell body.
The axon is a long extension of cells where information leaves the nerve cell and is passed on to target cells.
Therefore, the axon is the part of the nerve cell that transmits message from one nerve cell to another.

Answer:
A monohybrid cross is a cross between two organisms with different variations at one genetic chromosome of interest.[1][2] The character(s) being studied in a monohybrid cross are governed by two or multiple variations for a single locus. To carry out such a cross, each parent is chosen to be ratio.
