Answer:
Eutrophication is what happens when nutrient levels become too concentrated in rivers, lakes, and oceans. Eutrophication is when the levels of nutrients and minerals in a body of water become too concentrated. It is usually induced by the release of nitrate or phosphate-containing substances into a water body.
Explanation:
When all the members of a species disappears, this is called extinction.

Under the dissecting microscope I was able to view the surfaces of specimens such as a feather, insect, and leaf.
Under the compound microscope I was able to view a leaf, blood, and algae. I was able to observe the surface of the specimens in greater detail then I was able to view the surfaces under the dissecting microscope. For an example under the compound light microscope I was able to view the leaves surface which contained multiple lines that intertwined into each other and rectangular chambers of green dots. But under the dissecting microscope I was only able to view the surface of the leaf which consisted of thin white cracks in the leaf.
Under the scanning electron I was able to view the internal structure of the following specimens: a leaf, blood, and algae.
Under the transmission electron I was able to view a more in depth internal structure of the following specimens:a leaf, blood, and algae. I was able to observe the intern
al structures of the specimens in greater detail then I was able to view the internal structures under the scanning microscope. For an example under the TEM I was able to study the internal structure of a leaf which consisted of long thick and thin black and gray lines coated with black rectangles and tiny dots littering he perimeter of what looks to be the internal structure of the leaf. But with the SEM I was only able to view the first layer of the leaf's internal structure which consisted of mushroom like figures surrounded be compound and single molecules.
Answer:
Option D, is composed of a fluid bilayer of phospholipids with embedded amphipathic proteins
Explanation:
The fluid mosaic model is the depiction of plasma membrane whose main components are phospholipids, cholesterol, proteins, and carbohydrates.
The structure of plasma membrane consists of two layers of phospholipid molecules which are amphipathic or amphipathic (they possess both polar hydrophilic and non-polar hydrophobic ends).
Protein molecules also possess both polar and non-polar side chains. However, their poly hydrophilic linkages are towards the outer side and non-polar or hydrophobic linkage is towards the inner side.
Option D is correct
Answer:
Second
Explanation:
The following six months will be spent growing. The weight of the fetus will multiply more than seven times over the next few months, as the fetus becomes a baby that can survive outside of the uterus.
