Rotation is the spinning of an object in one place. Revolution is the circling of an object in a given orbit (path).

Explanation:

When the earth rotates, it spins on its own axis which is tilted at 23.5 degrees. Thus, we can conclude that the earth rotates on its axis every 24 hours relative to the Sun.

When the Earth completes one revolution around the sun in a fixed orbit in 365.25 days. This means the earth takes approximately 365 days to completely encircle around the sun and return back to its original position.

(The extra .25 day is added every year to make up one full day. Hence, we see a leap year every 4 years).

The two locations are most likely to have both earthquakes and volcanoes are the plate boundaries which are very much prone to the conductance of Earth quakes. The answer to the question is option C.

These are the tectonic plates that are involved for the same.

Both  the volcanoes and  the earthquakes are  usually caused along the  same boundaries of  the tectonic plates  that are due to their own  movements along with the interactions. The movement in the  narrow zones that are  along the  plate boundaries which  causes most  of the earthquakes.

The Ring of Fire that is also referred to the Circum-Pacific Belt which  is a path  passing along Pacific Ocean  that is characterized by  the active volcanoes and the  frequent earthquakes . The major of Earth's  own volcanoes and earthquakes  usually take place only  along Ring of Fire.

Answer:

Bacteria are prokaryotes, lacking well-defined nuclei and membrane-bound organelles, and with chromosomes composed of a single closed DNA circle. They come in many shapes and sizes, from minute spheres, cylinders and spiral threads, to flagellated rods, and filamentous chains.

Explanation:

Answer:

Prokaryotes,both bacteria and archaea have prokaryotes, which means that the cells don't have a nucleus or other membrane-bound organelles in their cells. Like bacteria, the cells have a coiled ring of DNA, and the cell cytoplasm contains ribosomes for the production of cell proteins and other substances the cell needs.

Answer:

Polar regions

Explanation:

Because plants don't survive in the extreme cold and ice that cover these regions year-round.

Due to their intense and harsh environmental circumstances, polar regions like the Arctic and Antarctica often have the lowest levels of biodiversity. So, the correct option is B.

The term "biodiversity", which is short for "biological diversity", describes the range of living things and ecosystems that exist on Earth. It includes a wide range of species, genetic diversity within those species, a wide range of environments, and a range of ecological processes. Humans benefit greatly from biodiversity as it provides them with food, medicine and ecological services such as pollination and water and air purification.

Because of their intense and harsh environmental conditions, polar regions such as the Arctic and Antarctica often have the lowest levels of biodiversity. These regions have a relatively limited diversity of species because the cold and dry conditions make it difficult for many species to live. Furthermore, these areas often have low population density due to the severe environment and scarce resources.

So, the correct option is B.

Telomerase is an enzyme that longs telomeres, which are fundamental repeats at the ends of chromosomes whose length is associated with cellular aging.

Telomeres are specific long tandem repeats located at the ends of all chromosomes in the cells.

These repeats (telomeres) are fundamental during cell growth and cellular aging.

It has been shown that telomerase can avoid the shortness of telomeres and thus can be used to slow cellular aging.

The DNA of humans and mice is almost 92% similar. This similarity indicates that mice share a common ancestor with humans. Mice have a tail, while humans have a tailbone.

Humans and mice don't look alike, but both species are mammals and are biologically very similar. Almost all of the genes in mice share functions with the genes in humans.

That means we develop in the same way from egg and sperm, and have the same kinds of organs.

Thus, Mice have a tail, while humans have a tailbone is correct.

A: Suited for their environment

Explanation:

You can automatically eliminate B and C, since they both say that animals with adaptations that won't work with their environment would have a higher survival rate. This doesn't make sense; adaptations that wouldn't suit an environment would actually lower the population's chances of reproduction and survival.
That leads us to A and D. However, A would be the correct answer. Organisms with adaptations that suited their environment would help them (since it would make the organism more compatible with their environment), rather than having no change at all.

Hope this helped!

Answer: A. suited to their environment.

After an exposure of the cells to high-energy radiation many newly reproduced cells appear different due to mutation.

Mutation occurs in cells when the change or damage of deoxyribonucleic acid in the cell brings about alterations in the genetic makeup of the organism.

Mutation of genetic material is caused by environmental factors called mutagens.
