Explanation:
Fossils are the remains of long-dead organisms, preserved in rock. Because rocks are laid down in layers, one on top of the other, the fossil record is generally set out in date order: the oldest fossils are at the bottom. Running through the fossil record makes it clear that life has changed over time.
BRAINLIST PLEASE!
Answer:
<em>The above statement is false.</em>
Explanation:
<em>When a single nucleotide is changed at a particular position of the nucleotide sequence, then this change will result in the formation of a faulty protein. </em>
<em>This is because that particular position of the genetic sequence is associated with the formation of a particular protein. All the other proteins formed will be normal. </em>
<em>Hence, we cannot attribute all existing changes between the cichlid and coelacanth/frog on this single nucleotide change.</em>
However, if instead of replacement of a T with a C, an addition or deletion had been made, then the entire genetic code would have been altered. This would have resulted in more number of faulty proteins being formed.
Answer:
The given blank can be filled with motor proteins.
Explanation:
Both cilia and flagella are the projections arising from the cell. They are formed of microtubules and are enveloped by an extension of the plasma membrane. They both are motile and are developed either to move the cell itself or to move substance over or around the cell. The main objective of cilia in mammalian cells is to move mucus, fluid, or cells over the surface.
Flagella are generally found on the gametes, however, they develop the water currents essential for circulation and respiration in coelenterates and sponges. Both cilia and flagella move due to the association of the cytoskeleton with motor protein, dynein. In combination, they are termed as axonemes.
Answer: it's A.Enzymes lower activation energy.
Explanation:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions.
