Answer:
Rate = 2 cm/year
Explanation:
It is given that, a plate moves 200m in 10,000 years. We need to find its rate in cm/year.
We know that, 1 m = 100 cm
200 m = 200 × 100 cm
= 20000 cm
Its rate is given by :
So, the plate is moving at a rate of 2 cm/year.
I would choose the second option because animal are not objects that don’t feel anything they kinda like human(they have feelings).
A scientific claim is developed by answering questions raised through suitable hypotheses that allow making predictions, which can be tested by experimental procedures.
<h3>What is a scientific claim?</h3>
A scientific claim is a body of knowledge obtained by answering the equation formulated through the observation of the real world.
These observations are capable of raising plausible explanations or hypotheses that can be tested (confirmed or rejected) by using the scientific method.
An inquiry activity may be, for example, the observation of the movement of a cylinder in aqueous solution.
In conclusion, a scientific claim is developed by answering questions raised through suitable hypotheses that allow making predictions, which can be tested by experimental procedures.

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.
