Answer:
b. the new species must be unable to breed with the original species.
Explanation:
By definition, species are defined as groups of similar organisms that can live and breed freely. This means that individuals in that species can interbreed and produce viable, fertile offspring. However, two different species cannot interbreed to produce fertile offspring due to biological barriers known as mechanisms of reproduction isolation.
These barriers are broadly classified as pre and postzygotic. Prezygotic barriers include the following:
- Habitat isolation: Two species occupy entirely different and distant habitats.
- Temporal isolation: Two species procreate at different times of the year.
- Behavioral isolation: Two species exhibit different mating behaviors.
- Gametic isolation: The gametes of the two species cannot fertilize.
- Mechanical isolation
Speciation, the production of an entirely new species, requires a maintenance of genetic diversity. Therefore, the new and original species cannot interbreed as this would limit the gene pool and decrease genetic variations.
Answer: The fact that teenagers often feel like adults far earlier than they develop the ability to make sensible, well-thought-out decisions reflects the fact that the limbic system often matures more quickly than the frontal lobe.
The correct option is D (limbic system; frontal)

Answer:
The average temperature of a freshwater wetland in summer is 76 degrees Fahrenheit. The average temperature in winter is 30 degrees Fahrenheit. The climate in freshwater wetlands is usually semitropical, as freezing conditions rarely occur.
Explanation:
The most common freshwater wetland is swampland. The freshwater biome is located on every continent except for Antarctica. Most people think of it being a nuisance, but freshwater wetlands are an important part of our ecosystem. More examples of freshwater wetlands are marshes or bogs. In freshwater wetland the water will always be standing water. Most of them will have water in them all of the time, but some will only have water in them during certain parts of the year. There are 4 different seasons in freshwater wetlands. There is Summer, Fall, Winter, and Spring. The average temperature of a freshwater wetland in summer is 76 degrees Fahrenheit. The average temperature in winter is 30 degrees Fahrenheit. The average rainfall in a freshwater wetland is 59 inches or 150 centimeters to 200 inches or 500 centimeters. The freshwater wetlands get and average of 7-10 hours of sunlight a day throughout the year.
Answer:
a. Determine the allele frequencies of:
f(T) = 0.485 ≅ 0.48
f(t) = 0.515 ≅ 0.52
b. Determine the genotype frequencies of the exposed generation
- F (TT) = 0.21
- F (Tt) = 0.55
- F (tt) = 0.24
the genotype frequencies of the next generation
- F(TT) = 0.23
- F(Tt) = 0.5
- F(tt) = 0.27

During prophase, the complex of DNA and proteins contained in the nucleus, known as chromatin, condenses. The chromatin coils and becomes increasingly compact, resulting in the formation of visible chromosomes. Chromosomes are made of a single piece of DNA that is highly organized.
