What is a nonnative species?
I am Lyosha [343]

Answer:

<em>The correct option is D) A species that does not normally live in an area.</em>

Explanation:

Non- native species can be described as a species which do not live in a particular habitat but are introduced into the habitat due to certain reasons or causes. The introduction of non-native species might badly affect the stability of an area. The non-native species might fight with the native species for resources like food, water, shelter etc. Sometimes, the introduction of non-native species is done so that the species can feed on any other species which is not beneficial for that environment.

State two examples of situations where active transport occurs
Cloud [144]

When something needs to be transported against its concentration gradient, or a molecule is too big to simply diffuse through a membrane, active transport has to be used. So active transport requires energy (ATP).

Examples:

1. Antiport pumps: transport one substance in one direction while transporting another substance the other way. An example of this is the sodium-potassium pump.

2. Symport pumps - uses a substance that wants to move from an area of high concentration to low concentration and carries another substance against its concentration gradient. An example of this is the sodium-glucose transport protein

3. Endocytosis - large amounts of extra cellular fluid can be taken into a cell - needs ATP to bind proteins in the cell membrane and causes them to change their shape...which eventually causes the surrounding of the fluid to be brought in (a vesicle).

4.exocytosis - opposite of above
