The wind makes pollination possible for gymnosperms. In gymnosperms ovaries are absent and the gametophytes of these plants are present on cones rather than flowers. Unlike angiosperms that get pollinated with animal interference, wind plays a crucial role in gymnosperm pollination.
According to studies, 80% of the data that we take in comes from our power of sight. Sight lets us take in 180° of images, perceive 1 million different colors, adjust what we see based on level of light & focus close up or miles away. Our vision is more detailed than any digital camera.
Natural selection act directly upon <u>Alleles</u>
Explanation:
Genes, such as that of fur color, have many variants called alleles. Natural selection act on the alleles and chooses the best fit for an environment and eliminates the disadvantageous ones from the population over generations. Mutations are a rare occurrence that increases the number of allelic variants of a genes on which natural selection can act upon.
Answer:
The gene for human insulin is inserted into the gap in the plasmid. this is done through the use of restriction enzymes and ligase to insert and close the plasmid. This plasmid is now genetically modified. The genetically modified plasmid is introduced into a new bacteria or yeast cell. The more the cells divide, the more insulin is produced as bacteria divides into two identical daughter cells like in mitosis.
Explanation:
<span>Rather than being learned, glucose aversion is inherited as an autosomal incompletely dominant trait, which appears to he controlled by
a single major gene. This was discovered through a study done on cockroaches, some were fed regular bait while some were fed bait laced with glucose. Through time they began to avoid the glucose.</span>
