In North America, the eastern spotted skunk mates
in late winter, and the western spotted skunk mates
in late summer. Even though their geographic
ranges overlap, the species do not mate with each
other. What most likely prevents these two species
from interbreeding?
A. habitat isolation
B. gametic isolation
C. geographic isolation
D. reproductive isolation
Answers
Reproductive isolation is a mechanism through which species do not get to interbreed. Option D. reproductive isolation
What is reproductive isolation?This is a mechanism through which different species or populations do get to mate and produce fertile offspring. This mechanism allows the accumulation of genetic differences and favors speciation.
There are different barriers that inhibit or interrupt the genetic flow between different species.
Reproductive barriers prevent mating between two or more species. There are two types of barriers,
prezygotic ⇒ that avoids fertilization between individuals of different species, postzygotic ⇒ that impedes the zygote to develope and reach the adult stage.Pre-copulatory o pre-ziygotic:
• Ecological or by habitat isolation;
• Seasonal or temporal;
• Séxual o ethologic;
• Mechanic;
• Gametes incompatibility.
Postzygotic mechanisms or barriers include
• Hybrid inviability,
• Hybrid sterility,
• Cytoplasmic interactions.
In the exposed example occurs a seasonal difference between the mating period of the eastern spotted skunk and the western spotted skunk.
Probably, if both of them would mate during the same season and in the same area, they could reproduce.
However, since their mating season differs, individuals from each species do not get to cross and hence, produce fertile offspring.
Option D. reproductive isolation is what most likely prevents these two species from interbreeding

17. Explain how carbon reservoirs can
be accessed without the influence
of humans.
Answers
Answer:Without human interference, the carbon in fossil fuels would leak slowly into the atmosphere through volcanic activity over millions of years in the slow carbon cycle. ... About half of these emissions are removed by the fast carbon cycle each year, the rest remain in the atmosphere.
Explanation:Hope this helps you!
In the slow carbon cycle, volcanic activity would release fossil fuel carbon into the atmosphere over millions of years without human intervention. The rapid carbon cycle removes half of these emissions annually, leaving the rest in the atmosphere.
What are 4 carbon reservoirs?
These are the reservoirs or sinks that carbon moves through as it cycles through the environment. Carbon is returned to the atmosphere through a wide number of different processes, including the decomposition of organisms, the eruption of volcanoes and fires, the combustion of fossil fuels, and more.
Carbon reservoirs contain substantial quantities of carbon between processes.
Burning fossil fuels such as natural gas, coal, and oil releases CO2, which is damaging to the environment and to individuals.Using fossil fuels reduces carbon stores as well.
Toxic gases and smoke are released by industrial chimneys as a result of the combustion of fossil fuels.
Therefore, the carbon stocks such as fossil fuels have been used by humanity.

Use the data you calculated in parts A and B to explain why gypsy moths could threaten biodiversity in the ecosystem.
Answer: edmentum
The number of gypsy moths is growing exponentially in a short period of time, which suggests that there are few predators controlling their population. This growth also aids the exponential destruction of shrubs and trees, which native species rely on for food and shelter. Increased competition for these resources will likely cause the population of many native species to decline. Over time, some of the native species may die out or leave the area, leading to a decline in biodiversity.
Answers
Answer:
The number of moths are growing fast in just a short period of time, this means that their poulation is being controlled by their predators. As the population of the moths continue to grow, there will be an increase in the destruction of crops and trees within the moth's environment. Over time some of the species may die out and cause them to relocate and cause a decrease in biodiversity.
Explanation:
I put this answer in my own words, so you may copy and paste it.
The caterpillar of the Gypsy Moth provokes tree damage but since it is the only stage of the life cycle that utilizes food. When the population of feeding caterpillars reaches pandemic proportions, they can completely defoliate trees.
What is a biodiversity?The term biodiversity pertains to the diversity of life on Earth at all levels, from genes to ecosystems, and can encompass the evolutionary, ecological, and cultural processes that enable life to exist.

A storyboard is a sequence of drawings, along with some description or dialogue, that illustrates and represents the scenes of a story or movie. Create a storyboard for the process of gene expression/central dogma depicting the story of how the cell uses the information in DNA to synthesize a protein.
Answers
Answer:
By decoding information with the help of transfer RNA (tRNA).
Explanation:
The cell uses the information in DNA with the help of transfer RNA (tRNA) to synthesize a protein because transfer RNA (tRNA) decode a messenger RNA (mRNA) in order to produce proteins according to the information present in messenger RNA (mRNA). The information about protein is stored in a gene's DNA which is passed to a RNA in the cell nucleus which is responsible for formation of copies of DNA in the process of translation. So the cell uses the information of gene's DNA with the help of RNA molecules.
