Q1.16 Suppose an entire village from a very wet region of Africa escaped mosquitoes by moving to an unpopulated area in a dry region. How would the move change people's fitness?

Answers

Answer 1

Answer:

Explanation below.

Explanation:

The movement will help the people to exercise more.

It should be understood that the presence of mosquitoes and the situation of the region as a wet region will not allow people to do much exercise, but their movement to the dry region will allow them to do more exercise than that of the wet region.

Answer 2

People and increase is the correct answer to the given fill in the blanks.

Population and area:

People's relative fitness would improve on average because agricultural crops would be harder to manage in dry places, resulting in a lack of nutrients in the population, leading to disease.

The urban population grows while the rural population shrinks as a result of population migrations. This lowers worker productivity in rural regions, causing them to go dormant, and increasing the strain of urban expansion on them.

What is Climatic change?

Climatic change may be defined as a type of process that significantly involves long-term alterations in the temperature and weather pattern of a particular location. These alterations are completely natural and rely upon the solar cycle.

The role of the oceans is determined by the fact that they regulate the climate of particular locations by absorbing 25-30% of the carbon produced by humans in the environment. Due to this, they are considered the largest store of carbon accounting for approximately 83% of the global carbon cycle.

Therefore, oceans remove about 25% of the atmospheric carbon dioxide produced by humans is the statement that represents the role of oceans that play in moderating climate change. Thus, the correct option for this question is C.

what would happen if a new predator was introduced into the ecosystem that only ate mice ?

Answers

Answer:

The ecosystem would drastically change.

Explanation:

Here is a food chain that involves mice:

Sunlight -> Berries -> Mice -> Snake -> Bald Eagles

So, let's say a new animal was introduced, and it eats mice. There would be more berries, as the mice wasnt eating them, the snakes would start to starve as there is not as many mice, and the bald eagles may start to starve as no more snakes for them to eat!

I hope you understand, and have a wonderful day!

He may not know to use ecosystem in overcoming his hunger , he may end up.starving and at last he would choose to eat plants and he will adapt with the nature of ecosystem .

In second case ,

he may get disturbed / fruatated and destroy the whole ecosystem .

in third case ,

he may not know how to use the ecosytem and die not eating anything .

So , if overall we see , our animal may die in two cases . the only case how an meat eating animal will survive in new environment is by adapting himself , but is he could not then he will die . so living - dying ratio is 1:2 . so we can predict that the animal will not survive . But as we know animals are not like new era humans and dont have tantrums like em' , so they will adapt . but adaptations take a lot time , before that the animal dies because of aging then nothing can be done .

Infact , this is how humans has evolved from a monkey to a social animal . we all know that humans have been fast devaloping animal and thats what we are today , but there was no one to force human to evolve as a whole im trying say there was no disturbance because of any other species in case of human .

so because of disturbance that animal may or may not adapt .

the answer is depends .

A

Explanation:

My guess would be A.

It’s excepted by the scientific community that climate change is a thing, and that we human are the cause.

We know this, because of the type of carbon that in the air is the same type as those found in fossil fuels.

So, because carbon dioxide is a greenhouse gas, one of the predictions is that as we add more carbon dioxide in the atmosphere the earth gets warmer, and the polar icecaps start to melt and that adds to the volume of the sea water.

So, it’s A.

Maple and oak trees are both deciduous angiosperms, so the wood each produces is classified as a hardwood. However, the difference between maple and oak wood is significant, and it would be difficult to mistake one for the other. All species of oak display a distinctive well-defined grain pattern whereas the maple wood grain tends to be creamy white with little visible grain. The differences don't stop there, but to really appreciate them, it's important to realize that within the broad category defined by oak is a subset of species that differ significantly from each other.
