Which part of fried shrimp provides the most energy in the form of glucose to help power cellular respiration
Answers
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?
Answers
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.

According to scientific thought, when does one species of organisms become two species? Question 2 options: when populations become separated from one another when one population becomes extinct when populations compete for the same resources when one population cannot interbreed with the other population.
Answers
According to scientific thought, the correct option to this is when does one species of organisms become two species When populations compete for the same resources as one population.
When one population cannot interbreed with another then it is called speciation. For example, if a cross between fertile and infertile is produced.
What is the evolutionary procedure of speciation?The evolutionary procedure of speciation is how one populace of a species modifications over the years to the factor wherein that populace is awesome and might now not interbreed with the “parent” populace. Often a bodily boundary divides the species into two (or more) populations and continues them from interbreeding.
Hence clear it is that populations compete for the same resources when one population.

Mutation refers to changes to the DNA base sequence of organisms. This can be caused by a variety of factors.
In a population of high density consisting of a single species, the frequency of mutation is usually high.
Mutation will create phenotypically different organisms within the same species population. These organisms are known as mutants and not only phenotypically different but also genetically variant.
