Ans.

Chimpanzees and gorillas are considered as more closely related to humans as compared to monkeys. It is because apes have a larger brain, longer life-span, higher intelligence, longer legs and show absence of tails as humans, while monkeys have a smaller brain, short-life span, short legs, and tails.

Thus, the correct answer is option A). apes are larger than monkeys and have long legs and no tails.

Scientists believe that great apes such as chimpanzees and gorillas are more closely related to humans based on the evolutionary timeline because apes are larger than monkeys and have long legs and no tails. Apes are known to have larger brains than monkeys which makes them so closely related to us. This fact cancels out B and C for the answer. Also, apes (gorillas, orangutans, etc.) are much larger than monkeys (mandrill, lesula, etc.). This right away cancels out option D. What's left is option A which features body parts and comparisons that are comparatively accurate towards humans. Hope this helped :))

nevsk [136]
<span>The correct answer is B. their kidneys can't excrete concentrated salt. Since salt is dissolved in water, the organism sends its water reserves to the kidneys to dissolve and excrete the salt but this leads to dehydration. That's why people at sea who don't know what they're doing often dehydrate themselves by drinking sea water, thinking that they're safe.</span>

Match the rocks with the material they are made of. igneous rocks /sedimentary rocks /metamorphic rocks
Vlad1618 [11]

The answers would be:

Igneous Rocks - They are made from hot magma.

Sedimentary Rocks - They are made from weathered pieces of rock.

Metamorphic Rocks - They are rocks, small or large which reformed due to high temperature.

If you'd like to know more, read on:

Igneous rocks are formed when hot magma is cooled and then it hardens into a rock. The word igneous comes from the word, "ignis" which means "of fire. They can be formed beneath the Earth or on the surface.

Sedimentary rocks are formed from weathered pieces of rock. These pieces are called <u>sediments</u>. They can also be made out of other material. When these sediments settle, it continues to do so until so much sediment accumulate and they start to press down on each other. The sediments then start to go through compaction and sedimentation which for a sedimentary rock.

Metamorphic rocks form under heat and pressure. They are squeezed and shaped and go through <u>metamorphosis </u>or go through change. A metamorphic rock can be formed from any other type of rock as long as it goes through changes due to intense pressure and/or heat.
