How is a loss of biodiversity most likely to affect an ecosystem?

2 answers:

All the plants and animals in a ecosystem relay on each other to survive so loss of 1 species would mean numbers of others would fall and some may rise too muck

Loss of biodiversity affects the ecosystem in many ways. For example, if a species disappears, the animals/plants that it fed on will suddenly increase in population due to loss of predators. The predators of the lost species, however, will go down in population because its main source of food has disappeared.

Answer:

indeterminate

Explanation:

The answer would be <u>an indeterminate number of generations.</u>

The blue trait is a heterozygous trait. In other words, the blue allele does not really exist. Two different alleles team up to produce the trait, whereas, only two the same allelic conditions can produce a true-breeding flock.

<em>Hence, it will take an indeterminate number of generations to produce a true-breeding flock of the Blue Andalusions.</em>

In a large population of plants, notches in the leaves are caused by a dominant allele N and lack of notches by a recessive alle

Jobisdone [24]

Answer:

Explanation:

If the population is in equilibrium, the allele frequencies will be constant.

There is nothing about the heritability of dominant or recessive alleles that make dominant ones any more likely by nature. This rules out choices A and B.

Genetic drift mentioned in D refers to alleles leaving a population. Nothing like this was mentioned in the question, so count that answer out.

C is the only remaining answer by process of elimination. It is also the most logical choice. Directional selection refers to a process of natural selection wherein extreme phenotypes (notched leaves, or non-notched leaves) are favored. In this case, there may be some external pressure causing notched leaf plants to be more evolutionarily fit, meaning that they survive long enough to reproduce more and increase allele frequency of the dominant allele.

What is the primary advantage of noneugenol periodontal surgical dressing over periodontal surgical dressing that does contain e

daser333 [38]

Some people may develop redness and burning discomfort in the vicinity of the bandage if they are allergic to eugenol.

In order to lower the danger of surgery site infection and bleeding, speed up wound healing, and lessen patients' pain and discomfort, periodontal dressings were devised.
The ability of eugenol-based dressings to numb pain and make sites less sensitive made them popular in the past, especially after gingivectomy.
Based on its antibacterial qualities, zinc oxide-eugenol dressings appeared to prevent or delay bacterial development. However, it was discovered that eugenol irritated oral mucosal tissues, caused allergic reactions, and caused tissue necrosis, especially in bone, which slowed the healing process.
Thus, noneugenol periodontal surgical dressing are preferred.
