Meiosis results in 4 haploid cells.
Explanation:
Meiosis undergoes two cycles namely: meiosis 1 and meiosis 2
Meiosis occurs in germ or sex cells in which four haploid daughter cells are formed each having one of a chromosome pair that exists in diploid cells.
The muscular system of an organism controls the organism’s muscles. When a hummingbird’s muscular system is affected, the muscles will become weak from a disease and they will potentially die because they will not be able to survive without the strong support of their legs or any other muscle in its body.
Answer:
granular cells of the juxtaglomerular apparatus
Explanation:
Renin is a secreted hormone, stored and produced by granular cells. This enzyme is responsible for regulating the water gradient in the human glass and blood pressure. This enzyme helps regulate the extracellular gradient in the blood cell plasma and controls any problems that may appear in the arteries or in all blood vessels in the body.
FULL ANSWER<span>The five main phases of mitosis are prophase, prometaphase, metaphase, anaphase and telophase. Some mitosis timelines include interphase, where the cell begins preparing to undergo mitosis. Prophase is the official start of mitosis, and during this step duplicated DNA strands condense into a more compact form and take on the traditional X shape of chromosomes.During prometaphase, the membrane around the cell's nucleus dissolves so that the chromosomes can move into place at the center of the cell. Spindle fibers align the chromosomes in the center of the nucleus during metaphase. This phase is essential to the health of the daughter cells, since it lines the chromosomes up evenly so they can be easily split in the next phase.Anaphase is the phase where two different cells start truly forming. The chromosomes are pulled apart, and half of each chromosome is pulled to separate ends of the cell, creating two bundles of chromosomes.In telophase, these bundles of chromosomes are enclosed in a new nuclear membrane. Once safely enclosed, the chromosomes break up again and lose their compact look. Finally, in cytokinesis the two sides break apart to create two new identical daughter cells.</span>
The correct answer is: A. The hydrophilic head groups of the lipid molecules are exposed to the outside of the cell and the cytoplasm, which is a water-like environment. The hydrophobic tails form an oily layer inside the membrane that keeps water out of the cell.
Plasma membrane of the cell is arranged in a bilayer of phospholipids. Phospholipids are amphipathic molecules which means that they have both hydrophilic and hydrophobic regions. The hydrophilic heads of phospholipids that are faced outward and hydrophobic layer located in the interior of the bilayer together make a good barrier between the interior and exterior of the cell, so the water and other polar or charged substances cannot easily cross the hydrophobic core of the membrane.
