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.

Cnidarians were the first phylum that scientists saw tissue level organization in. Tissue level organization meaning cells all of one type start to function in a unified way.
Answer: In the middle intertidal, barnacles, mussels and seaweeds all compete for space – a precious limited resource. Mussels are generally the dominant competitor on rocky shores and without the presence of predatory seastars would outcompete other taxa and occupy all available space.
I'm not 100% sure which biology class you are in are you doing the moth activity? If so then I would believe that the light moth would be easier to see on a dark tree trunk
