Valves ensure blood flows toward your heart. Vein valves work to bring the blood that flowed down via arteries back up to your heart.
Muscle cells need a specific form of energy for contraction and cannot use the energy released directly from breaking down glucose or triglycerides. Rather, body cells must first convert food to adenosine triphosphate (ATP). <br /><br /> Food is digested and processed into ATP through sever different stages.
Answer:
Its Euglena
Explanation:
Shape change from normal elongated egg-shape to round-shape in stressful environment. These shape changes attain two transition phases. The I-transition phase is reversible where the organism can return to normal if favourable environment persists.
Answer:
Meiosis is a process in which sex cells, also known as gametes are made. Meiosis is different from mitosis in a lot of ways, one being that mitosis creates identical daughter cells and meiosis creates unique daughter cells. Meiosis is important because it allow for the creation of a meiosis nucleus. Cells produced by meiosis will be used in haploid, where each member of the next generation is genetically unique.
Cells produced in <u>sexual reproduction</u> will have half of the genetic information of body cells and will be genetically <u>unique</u>. This is necessary because when a sperm and an egg fuse together in sexual reproduction. They form a <u>zygote</u>: the first body of a new individual.
The new individual will now have cells that are <u>diploid</u>, meaning they have two sets of chromosomes. They zygote will have to do a lot of <u>mitosis</u> allowing it to grow quickly and ensure that all of its cells are genetically unique.
