Answer:
The environmental factors which need to be investigated before clearing the land can involve living and non-living factors. The land clearing will remove species of animals and plants acquiring their habitat in the forest. The loss of floral species will affect the faunal species. The faunal species will extinct, decrease in number or may migrate to different locations. Therefore, complete loss of biodiversity will result.
This will also result in disturbance important cycles in nature like water, oxygen, nitrogen and carbon which will lead to disturbance of rainfall, seasonal or weather changes. Soil an important non-living factor will loose it's fertility due to soil erosion.
The role of the retina is to receive light that the lens has focused. It then converts the light into neural signals which get sent to the brain for visual recognition.
The information stored in the order of bases is organized into genes: each gene contains information for making a functional product. The genetic information is first copied to another nucleic acid polymer, RNA (ribonucleic acid), preserving the order of the nucleotide bases. Genes that contain instructions for making proteins are converted to messenger RNA (mRNA). Some specialized genes contain instructions for making functional RNA molecules that don’t make proteins. These RNA molecules function by affecting cellular processes directly; for example some of these RNA molecules regulate the expression of mRNA. Other genes produce RNA molecules that are required for protein synthesis, transfer RNA (tRNA), and ribosomal RNA (rRNA).
A white dwarf is what stars like the Sun become after they have exhausted their nuclear fuel. Near the end of its nuclear burning stage, this type of star expels most of its outer material, creating a planetary nebula.
