Answer: Gradualism and punctuated equilibrium are two ways in which the evolution of a species can occur. A species can evolve by only one of these, or by both. Scientists think that species with a shorter evolution evolved mostly by punctuated equilibrium, and those with a longer evolution evolved mostly by gradualism.
Explanation:
The only exception would be nuclear energy. Heavy elements like Uranium got their stored energy from ancient supernovae, that doesn't come from the sun. And fusing hydrogen is tapping energy that has been around since the Big Bang.
Hope this helped :)
Answer:
step 1: mRNA attaches to the ribosome
step 2: tRNA's attach to free amino acids in the cytoplasmic "pool" of amino acids
step 3: tRNA carries its specific amino acid to the ribosome
step 4: tRNA "delivers" its amino acid based on complementary pairing of a triplet code (anticodon) with the triplet code (codon) of the mRNA
step 5: Enzyme "hooks" the amino acid to the last one in the chain forming a peptide bond
step 6: Protein chain continues to grow as each tRNA brings in its amino acid and adds it to the chain
Answer:
Because it contains two different sex chromosomes
Explanation:
Man in its genome contains two sex chromosomes, X and Y, while woman contains two X chromosomes.
In order to be a carrier of a sex-linked trait, a person should have one copy (one allele) of a certain trait. For example, if a female has one X chromosome with mutation (e.g. disease carrying) and one normal X chromosome, she is carrier for the disease. But, on the other hand if a male has one X chromosome with mutation he will develop that disease.
Another name for cell cycle is called mitosis
