What is another way genetic variation increase in a population?

Biology
1 answer:
Tcecarenko [31]3 years ago
5 0

Answer: The flow of individuals in and out of a population introduces new alleles and increases genetic variation within that population. Mutations are changes to an organism’s DNA that create diversity within a population by introducing new alleles.

dangina [55]

Answer:

d. dynamic receptor proteins

Explanation:

In the skin there are several receptor cells that can pick up various stimuli such as temperature, pressure and pain. They can be classified into mechanoreceptor, thermoreceptor and pain receptor cells.  When we are dealing with mechanical stimuli like pressure, mechanoreceptors respond to stimuli by sending the signal to the brain.

Light touches on the skin are received by nerve endings called Meissner corpuscles and Merkel discs. Already more intense pressures (such as a handshake) are received by receptors called Pacini corpuscles.

A remora hitching a ride on the shark is an example of which symbiotic relationship? A. Predator/prey B. Mutualism C. Parasitism
Lelechka [254]

Answer:

D. Commensalism

Explanation:

The relationship between a remora and a shark is an example of commensalism - it's good for one side but neither good nor bad for the other. The remora attaches itself to the shark and gets the benefit of eating the shark's leftovers, but there is no harm or benefit for the shark, and the shark doesn't eat the remora like in a predator/prey relationship.

Dandelions grow quickly and produce many seeds, ensuring that at least some plants will survive and produce seeds themselves. Wh
Pani-rosa [81]

Species strategies to survive and successfully reproduce define three basic survivorship curves. <em>The survivorship curve </em><em>type III</em><em> is the one that best represents the Dandelion plants.</em>

------------------------------

According to the species strategies to survive, reproduce, and ensure their reproductive success, we can mention three basic curves,

<u>Type I.</u>

  • Mortality often occurs at the end of the cycle, representing species with low mortality.

  • Organisms exhibiting this type of survivorship curve have long life cycles and high probabilities to survive until they are old enough.

  • These species have few descendants and spend too much time and energy in parental care to ensure their reproductive success.

<u>Type II.</u>

  • The probabilities of dying are equals all along the cycle, at any age interval.

  • The number of dead individuals remains constant from the beginning to the end of the life cycle.

  • These species have reduced offspring, and they ensure their reproductive success by providing some significant parental care.

<u>Type III.</u>

  • Significant mortality during the early stages of life.

  • Only a few individuals reach the later life stages, getting to survive their first period of life. Survivors usually have a long life.

  • These species produce large offspring at the same time, but they provide little or no parental care.

  • The reproductive success of these species depends on the number of descendants and not on the parenting time spent.

According to this information, and the characteristics of the <em>Dandelions, we might assume that this species is represented by type III curve.</em>

The graph below is of directional selection. Which statement can be supported by the evidence shown in the graph?
7nadin3 [17]

<u>Answer</u>: C) Directional selection occurs when one of two extreme phenotypes is selected for.

The type of natural selection known as directional selection is defined in population genetics in the case in which an extreme phenotype is favored over other phenotype. Thus, the population and its allele frequency will evolve towards this end of the trait spectrum (extreme phenotype). This is also the case illustrated in the graph where the right side represents the extreme phenotype.

Which statement best describes cellular resperstion?
pentagon [3]

Answer:

C

Explanation:

Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
