<span>The answer is shared an evolutionary
history. Homologous structures evolved
from the same ancestor structure. An example of homologous features is the four
limbs of all tetrapods. In birds, the forelimbs evolved
into wings while in crocodiles they still used for walking, and in humans, they evolved into hands. </span>
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.
Answer:
D.)
Explanation:
(I know this, by experience :|)
Assuming a 10% trophic efficiency, the herbivore (primary consumer) will get 10% of the producer energy. Then, the second consumer that eat the herbivore will get 10% of the primary consumer energy, so it is 10%*10%= 1% of the primary producers.
Then, the t<span>ertiary consumer should get 0.1% of the primary producers' energy.</span>

Answer:</h2>
<h3>In a fat molecule, the fatty acids are attached to each of the three carbons of the glycerol molecule with an ester bond through the oxygen atom. During the ester bond formation, three molecules are released. Since fats consist of three fatty acids and a glycerol, they are also called triacylglycerols or triglycerides.</h3>
