Answer:

Bacteria capsule.

Explanation:

The bacteria capsule is a layer of polysaccharides that is around the bacteria membrane. Its principal function is to protect the bacteria from dehydration, destructive toxins,  and cells that can destruct the bacteria, such as phagosomes. As a result, the bacteria have a higher probability of surviving and colonizing.

Which of the following statements about eutrophication is TRUE?
Nostrana [21]

Answer:

C. It is driven by natural processes like rock weathering and nitrogen fixation.

Explanation:

It has been discovered that eutrophication occurs through a gradual increase in the deposition of phosphorus and nitrogen and other plants nutrients in the water bodies.

This will allow the maximum growth of algae on the surface of the water.

It has been discovered that eutrophication is not good for the water bodies. This is because, the excess growth of algae on the surface of the water will prevent the sunlight from penetrating the water, thereby preventing the plants inside the water from making use of the sunlight to carryout photosynthesis. Also, it will prevent oxygen from entering, thereby depriving the organisms in the water from having the necessary oxygen needed for respiration.

PLS HELP!!!!
zzz [600]

Explanation:

Frog undergoes a complete metamorphosis. It includes the egg, tadpole, froglet and then adult frog stages. In complete metamorphosis the hatchling does not resemble the parent and changes as it grows to be an adult.

During metamorphosis the tadpole will develop back legs first, then front legs.  Around 6 weeks of life the mouth starts to widen.  Sometime around 10 weeks the froglet’s, as it is now called, eyes start to bulge out and the tail begins to shrink and eventually disappear.  When the lungs finish developing the froglet makes it’s way onto the land and, Ta-da! It’s a frog!

Hope this helps!
