An animal eats the seeds, and later when the animal poops, the seeds are spread through the feces
Answer:
B.hydrogen bonding within polypeptide strands
Explanation:
Alpha helix is one of the secondary structures formed by polypeptide chains. It is formed when the backbone of a polypeptide is wound around a longitudinal axis. The side chains of the amino acids are oriented outwards. Alpha helix structure is stabilized by the formation of a maximum number of hydrogen bonds between the amino acids of the chain. The hydrogen atom linked to the electronegative nitrogen atom of a peptide bond form hydrogen bond with the electronegative carbonyl oxygen atom of the fourth amino acid.
In this way, every peptide bond except the ones present close to each end of the helix take part in hydrogen bonding and stabilize the structure.
Answer:
The correct answer is E) density-dependent regulation.
Explanation:
When the population growth rate is dependent on the density of a population then it comes under density-dependent regulation. Usually, when a population becomes denser the mortality rate becomes high in that population.
This regulation can occur due to factors like predation, disease, inter or intraspecies competition. So here when the density of the mosquitoes becomes high then purple martin flock to the area and specialize in them to gain nutrition which stabilizes the population of mosquitoes again.
Density-dependent regulation is more significant when the population density of a species increase. So the right answer is E.
That would be electric charge
Solar energy because of the sun's rays
