A nonnative species may not have any natural predators when being introduced subsequently it won’t have any competition with the other organisms living in the same ecosystem. This will make the other organisms struggle for food and other resources and could potentially make them go extinct. They can also have drastic effects to the local biodiversity (for the previous reason). Also, due to the competition or newly introduced predator (assuming they’re a predator) the preexisting organisms of the ecosystem may start to relocate and start a new ecosystem or if there are neighbouring towns/cities may have to forage for food there - which would obviously be dangerous for both them and us. Hope these few examples help.

Answer:

Anaerobic respiration

Explanation:

All living organisms require energy for survival. They obtain this energy via the process of cellular respiration, where they breakdown the energy in their ingested food. However, the process of cellular respiration can either be aerobic (with oxygen) or anaerobic (without oxygen).

Anaerobic respiration is carried out by organisms who do not require OXYGEN for the process. This is the case of the bacteria described in this question which survive in a puncture wound that has healed on the outer surface of the skin in an environment without oxygen present. The type of respiration carried out by this bacteria is ANAEROBIC RESPIRATION.

Yasmine is asked to describe the structural organization of chloroplasts. She writes the following sentence:

julia-pushkina [17]

Answer:

C. Exchange the positions of "stroma" and "grana."

"A chloroplast contains thylakoid stacks, called grana, that are surrounded by fluid-filled stroma."

Explanation:

A dynamic biochemical process, photosynthesis, occurs within the chloroplasts of plants. Here, to form stable carbohydrates, light energy is transformed into chemical energy.

6 CO2 + 6 H2O + light → C6H12O6 + 6 O2

Carbon Dioxide + Water + Light Glucose + Oxygen

Chloroplasts are tiny, highly-folded, membrane-bounded organelles containing enzymes, pigments and other molecules that mediate photosynthesis. In the stack of grana, pigments like chlorophyll, absorb light energy for the light-dependent reactions.
