Answer:
<h2>RNA nucleotides may also bear adenine , guanine and cytosine bases, but instead of thymine they have another pyrimidine base called uracil (U) . as shown in the figure above, each base has a unique structures with its own set of functional groups attracted to the ring structure... </h2>
Answer:
Yes
Explanation:
Mendel's law of segregation states that every individual possesses two alleles, and only one allele from each parent is passed on to the offspring. That means that you get 23 chromosomes from each of your parents.
The correct answer is: B) supply energy, primarily in the form of ATP, for the cell's work
There are two main types of metabolic reactions:
1. Catabolic reactions (catabolism) are reactions of molecule breakage-macromolecules are broken down to basic units (monomers) and energy in the form of ATP is released. Formed monomers are used for the synthesis of new molecules or are released as waste.
2. Anabolic reactions (anabolism) are reactions of synthesis or building up of the macromomolecules. Anabolic reactions require energy, which means that are endergonic process and that energy is powered by catabolic reactions.
Answer:
The belief that organisms originate from a common ancestor was much of the basis that the theory of natural selection was based on. Evidence of animals sharing the same trait, even though for some it appears to have no benefit to them, appears to have been at the root of this belief.
Charles Darwin was the first scientist to publish a coherent theory of Evolution by Natural selection. He wasn't the first to intuitively suspect that species evolved from a common ancestor, but he was the first to publish a coherent theory and bring forth evidence for it.
