The number of chromosomes for the gamete of each of the species would be half of that of their vegetative cells.
Haploid cells contain half (n) the number of chromosomes of diploid cells (2n)
Gametes are generally haploid in nature.
The human skin cells are vegetative cells (2n), thus a gamete of humans would have 23 or (46/2) chromosomes.
The frog sperm cell is a gamete cell. Hence, the chromosome number remains 12.
In other words, human gametes will have 23 chromosomes while frog gametes will have 12.

Answer: Human 23; frog 12
Explanation: Skin cells are somatic cells, that means the they build the body and divide by mitosis. This kind of cells have genetic charge 2n or twice of the gamete's chromosomes, so a human gamete (sperm or ovum) has 23 chromosomes (46/2 = 23).
Frog sperm cell is a gamete so it has the number of chromosomes for this type of cell which is 12
Answer:
The total energy production of a mitochondrion is enhanced by its large internal surface area.
Explanation:
All cellular activity requires energy, it is through mitochondria that this energy necessary for cell activity will be generated. Mitochondria has a large internal surface area, all of which strongly influences the energy production of this organelle.
To get energy, the cell necessarily needs glucose. Mitochondria have the function of breaking down glucose by introducing oxygen into carbon, what remains is carbon dioxide, which will come out through exhalation. This process performed by this important cellular organelle is known as cellular respiration. In order for cells to perform their functions normally, they depend on various chemical reactions that occur within the mitochondria.
Despite its great importance, mitochondria is a fairly small cell organelle. There are cells that have a large number of mitochondria, however, the amount of this organelle will depend on the function of each one. The more the cell needs energy to perform its vital functions, the more mitochondria it will produce.
Genetic mutations are the changes in the genetic code and composition of organisms.
Genetic mutation can occur due to many factors like insertion, deletion, inversion of chromosomes.
The correct answer is:
Option A. Some inherited genetic mutations can be good for the offspring.
Therefore, some inherited geneticmutations can be good for the offspring.

Explanation:
b) non-coding DNA
c) nucleoplasm
d) at the ends of the complete DNA strands
b.) The relationship is mutually beneficial.
c.) They share the same niche.
d.) One species benefits, while the other is neither helped nor harmed.
Answer:
C (they share the same niche)
Explanation:
Competition is a relationship between organisms resulting in a contest when both are trying to use the same resources related to their growth, reproduction and survivability. It is as a result of limited resources. Competition occurs in virtually all ecosystems in nature. This relationship develops when more than one organism in an environment has the same need for resources (niche) as another, to survive.
Each organism has a specific place in the ecosystem called NICHE. A species' niche is basically its ecological role or the function to which it is especially suited, which is defined by the set of conditions, resources and interactions it needs or can use.
The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources) or to put it in another way, two species in an ecosystem are bound to compete when they share the same niche (need for resources).
