Why are non-native species dangerous to ecosystems?

Biology
1 answer:
Vesnalui [34]3 years ago
8 0

Answer & explanation:

Non-native species may be animals, plants or microorganisms introduced into an ecosystem of which they are not originally part, but where they adapt and come to dominate, harming natural processes and native organisms.

When a new species is introduced into an environment other than its own, it may compete with others, prey heavily on some species, over-breed and even cause disease.

Therefore, it can be concluded that this action may cause the destruction of some species, directly affecting the balance of that ecosystem.

Under certain circumstances, potassium ions ( K + ) in a cell will move across the cell membrane from the inside to the outside.
dexar [7]

Answer:

8.18 × 10 ⁻²¹.

Explanation:

The potential energy may be defined as the energy stored in the rest objects. This energy is important for the maintenance of the concentration gradient in the cell.

The change in the potential energy can be calculated as follows:

W = v2-v1 × q.

Here, the charge of the proton is considered because k+ ions has been used.

W= 0 - ( - 70. 5 mV) × 1.602 * 10^-19 C.

W= 8.18 × 10 ⁻²¹J.

Thus, the answer is 8.18 × 10 ⁻²¹.

Lemur [1.5K]

Answer: incomplete dominance

Explanation:

Incomplete dominance is also referred to as partial dominance or semi dominance. It occurs when the two forms of gene in a trait combine in such a way that one does not have a dominance over the other one. Therefore, there's a blend of both genes in the physical appearance of such organism.

Therefore, a low pitched male voices (RR) and a high pitched male voice (rr). Heterozygotes have a baritone voice is an example of incomplete dominance.
