Answer:

Factors like native plants and other animals competing for the resources.

Explanation:

The most important one for human civilization would definitely be the native plants because they will turn to be the ones that can be cultivated in that specific type of soil. For example, in the raining forests, cultivation like potatoes is not possible, because it's not a native plant. Another factor could be the other animals, or native animals, that compete for resources in that ecosystem, as they also interact with it, they would also be part of the decrease or increase of carrying capacity.

Round seeds and yellow seed color are dominant to wrinkled seeds and green seed color. What is the probability of having offspri

Reika [66]

Answer:

Explanation:

This question involves two distinct genes; one coding for seed shape and the other for seed colour. The allele for you seeds (R) is dominant over the allele for wrinkled seeds (r) in the first gene while the allele for yellow seeds (Y) is dominant over allele for green seeds (y).

In a cross involving RRYY (homozygous dominant for both traits) and RrYy (heterozygous for both genes), the following allelic combinations of gametes will be produced:

RRYY- RY, RY, RY, RY

RrYy- RY, Ry, rY, ry

Using these gametes in a punnet square (see attached image), 16 possible offsprings will be produced. The genotypes of the offsprings in the ratio 1:1:1:1 will be:

RRYY (4)

RRYy (4)

RrYY (4)

RrYy (4)

According to the question, offspring that have wrinkled seeds and yellow seed color will have genotype: rrYY or rrYy.

This genotype is not one of those that will be produced by the cross between a RRYY and RrYy parent. Hence, the probability of having an offspring with wrinkled seeds and yellow seed color is 0%

What is the difference between a benign tumor and a<br> metastatic tumor?

den301095 [7]

A benign tumour is generally not dangerous as they grow usually within a membrane in one space. They can however grow really big in a short space of time and can cause pressure on neighbouring blood vessels which can be dangerous.

Metastatic or malignant tumours are dangerous and cancerous. After they grow, some cells break off and travel in the bloodstream to a different area of the body (usually the main organs) and forms a secondary tumour there. This keeps happening until the cancer has spread to all of the body.

How does symbiosis benefit the organisms that make up a lichen?

enyata [817]

Answer:

Each organism absorbs minerals produced by the other

Explanation:

Lichen is a symbiotic association between fungi and alga. The fungus is able to absorb essential mineral ions like calcium, phosphate and potassium better than the alga thus benefiting the alga. The fungus in return gets organic materials from the alga. The alga provides organic nutrients for the lichen through photosynthesis and the lichen provides protection from drying out because the alga lives within the fungus's cell wall.
