Which part of fried shrimp provides the most energy in the form of glucose to help power cellular respiration
Answer:The breading on the shrimp
Explanation:
A part of fried shrimp that provides the most energy in the form of glucose to help power cellular respiration is known as the breading on the shrimp.
What is Cellular respiration?Cellular respiration may be defined as a biological process that significantly leads to the production of energy in the form of ATP by the disintegration of glucose which we get from food molecules and oxygen.
The reactants of cellular respiration are oxygen and glucose while the products are carbon dioxide, water, and energy in the form of ATP.
The part of food products that power the process of cellular respiration must be highly rich in glucose in order to deliver as much as energy can possible.
So, the breading on the shrimp provides the most energy in the form of glucose to help power cellular respiration.
Therefore, the breading on the shrimp is a part of fried shrimp that provides the most energy in the form of glucose.

Some fish in a murky underground lake have lighter scales than the others. This makes it slightly harder for the lighter fish to escape detection
by predators but most light-colored fish live long enough to reproduce. A natural event separates the dark-scaled fish from their light
scaled cousins, and as a result a new species of dark-scaled fish emerges
Which statement accurately describes the scenario?
According to the given situation, the fish experienced an evolutionary change because of genetic drift.
What is genetic drift?
Genetic drift is the change in the frequency of a present gene variant or allele in a population due to random chance.
Genetic drift may cause gene variants to disappear completely and thereby reducing genetic variation and also causing rare alleles to become much more frequent and evenly fixed.
Thus, the fish experienced an evolutionary change because of genetic drift.

Through aerobic respiration (respiration requiring oxygen), the mitochondria breaks down glucose, with the use of oxygen, to produce ATP energy. Unlike anaerobic respiration, which occurs in the cytoplasm and produces less ATP energy, aerobic respiration occurs in the mitochondria and produces more ATP energy.
what effect did Darwin's travels to the Galapagos islands have on the development of his theory of natural selection?
Answer:
During his visit to the islands, Darwin noted that the unique creatures were similar from island to island, but perfectly adapted to their environments which led him to ponder the origin of the islands' inhabitants. Among those that struck Darwin so greatly were the finches that are now named in his honor.

explain why the release of pcbs into an aquatic ecosystem may have longer lasting negative impacts on organisms than the realase of synthetic nitrates
Why Pcb have lasting effect than nitrate in the aquatic habitat.
PCB bind to soil and other particles in the water but only small amounts will dissolve in water. Small concentrations of PCBs can also evaporate and be carried long distances in the air. PCB stay longer in the soil and sediments more than nitrate.
When PCB is inside the ocean or aquatic environment,the fish or water organisms will absorb it from the water and sediments in their habitat. Too much accumulation of it can lead to their death and when such aquatic organisms are consumed, it will prone bad health to humans and even foetus. Over accumulation of PCB will affect the heat of individual.
What is PCB?PCB or polychlorinated biphenyls refer to highly toxic and concentrated industrial substances. They pose serious health challenges to fetuses, babies and children and this can lead to developmental and neurological problems from continuous exposure to PCB
