Pollination is the act of transferring pollen grains from the male anther of a flower to the female stigma.

Answer:
A DNA sequence codes for the same proteins in different species
Explanation:
All living organisms store their genetic information in DNA (genetic material). The manner through which information in the genes are encoded is the GENETIC CODE. The genetic code comprises of all the codons that specifies amino acids in living organisms. The genetic code has several characteristics, which includes that the GENETIC CODE IS UNIVERSAL
The genetic code is said to be universal because all known living organisms use the same genetic code to encode their genetic information. This means that a DNA sequence codes for the same proteins in several different species. For example, codon AUG encodes the amino acid METHIONINE in every living organism.
Answer:
Decrease in water/oxygen levels of the aquatic environment
Explanation:
<u>The environmental pressure that would cause primitive fish to adopt the genetic capacity to live on land would be a decrease in water levels of the aquatic environment.</u>
A constant decrease in water level that keeps exposing the fish to dry land will enable natural selection to start selecting for traits that will enable them to survive on land, especially, the development of lungs in the place of gills, the capacity to walk instead of swimming, and the capacity to avoid desiccation.
<em>A decrease in water level will mean a decrease in the amount of oxygen available for gill's respiration. Respiration is an important process for any organism to stay alive. </em>
<em>A decrease in water level also means an exposure to sun. The heat from the sun could cause death by desiccation.</em>
<em>A decrease in water level means that movement (through swimming) will be limited. Movement is necessary for feeding and other biological activities.</em>
Exposure to more radiation. Human made and from the sun.
