Answer: If you look it up online it tells you exactly why, and has reasoning for everything and will be way more accurate.
Explanation:
Answer: alleles
Explanation:
Alleles are different forms of a given gene. Alleles are mutated forms of a given gene which controls a particular trait. For instance, the gene that codes for hemoglobin is denoted with the letter A but the gene has another variant denoted by S. In abnormal hemoglobin S (sickle hemoglobin), glutamate is replaced by valine at position 6 in the amino acid sequence of the two beta chains of hemoglobin. This change in the amino acid sequence causes the red blood cells to have a sickle shape resulting in sickle cell disease. Therefore hemoglobin A and S are alleles of a given gene.
Answer:
due to the rate of blood circulation
Answer:
plant cells, palisade mesophyll cell, spongy mesophyll cell
animals- mitochondria, ribosomes
All medical research is carefully planned, and this includes medical
research with animals. Experts who review a scientist’s proposed
experiment involving animals weigh several considerations before
approving each study.
The most important thing is that the research must be relevant
to human or animal health. Studies need to protect the animals’
welfare. That means that only the fewest number of the most
appropriate species may be used. Under federal law, all animals
must be treated humanely and undergo the least distress possible
