Explanation:
Answer:mutualism
Explanation:
In a mutualistic relation,both organisms involved benefit from the activities of each other. The benefits may be nourishment,shelter, protection etc.
In the above example,the birds are known to guide humans by responding to specific calls made by the human. They guide humans to beehives and then in return gets to feed on left over honey. Both the bird and human benefits by getting nourishment.
Mutualism is unlike parasitism where one of the organism involved benefits and the other organisms Is most likely harmed. It is also not commensalism, where one organism benefits and the other neither benefits nor is harmed
Cell regulation is conducted by special proteins. These special
proteins are enzymes which help in the regulation of bodily function. They hasten
the chemical reaction such as pepsin. Pepsin is a protein that helps in the
digestion of food in the body.
Answer:
e) Endosymbiosis.
Explanation:
According to the recent evidences, the eukaryotic cells with membrane-bound organelles originated by the process of serial endosymbiosis. According to this hypothesis, organelles such as mitochondria and chloroplasts originated when the symbiotic prokaryotes entered and lived inside other, free-living prokaryotic cells. For example, the evolution of double membrane-bound chloroplasts occurred when the photosynthetic bacteria (cyanobacteria) entered and lived inside the larger heterotrophic cells.
Likewise, the evolution of mitochondria occurred when the aerobic bacteria (most probably the purple bacteria) lived inside larger anaerobic cells. Gradually, the endosymbionts developed mutual relation with the host cells and the symbionts lost the ability to live freely outside the host cell.
Answer:
32%
Explanation:
Since the population is in Hardy-Weinberg equilibrium, the allele and genotype frequencies will remain constant over generations.
The frequency of the recessive allele (q)= 0.20
Since p+q= 1
so, p= 1-q
and p=1-0.20= 0.80
The frequency of heterozygous genotype (2pq) = 2 x 0.20 x 0.80 = 0.32 or 32%
Therefore, the expected frequency of heterozygous genotype in the next generation would be 32%.
