Your answer is (B.)
Fossils in newer layers if rock are generally estimated to be younger than fossils found in the deeper layers because it is closest to the surface. The soil and earth didn't have enough time to "bury" the remains of the dead animal ( Bury is used for a simpler term) underground. The farther down a fossil is the more likely it is older unless the animal tends to burrow. Seeing as the question is probably talking of older animals that is unlikely for an animal to burrow that far. So your answer is B.
I disagree with this statement. Asexual organisms are at a lower risk for extinction due to the fact that they do not need a partner to procreate. They have an easier time making offspring.
Chloroplasts
In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle—the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules. I have taken the test before
Answer:
3.
Explanation:
A classroom desktop is the least likely to grow bacteria because it is a relatively clean surface. The armpit of a human and a warm freshwater mud puddle are a more suitable habitat for bacteria because they are warm, and provide a relatively safe environment for them
<span>(According to Reference)
Whereas an onion epidermal cell has a cell wall, a human cheek cell does not. Instead, a semi-permeable membrane surrounds the cytoplasm of the cheek cell. While there are chloroplasts present in onion cells, they are absent in cheek cells. </span>
