Answer: Stem cell research has the potential to treat diseases that are currently burdened with high health care costs—especially chronic conditions such as heart disease, Alzheimer's disease or diabetes, the costs of which threaten to cripple the healthcare system.
Answer:
The correct answer would be (c)[m phase].
M phase or mitotic phase is the phase of the cell cycle in which the actual division of chromosomes (karyokinesis) into two daughter nuclei takes place.
It can be divided into four stages namely prophase, metaphase, anaphase, and telophase.
During anaphase, the sister chromatids of each replicated chromosomes are separated from each other and are pulled in opposite side with the help of mitotic spindle.
Then during telophase (last stage of M phase), the separated chromosomes reach either pole of a dividing cell. In addition, nuclear membranes are reformed around each chromosome set which forms the two daughter nuclei.
M phase is followed by cytokinesis which divides the cytoplasm, cell organelles, cell membrane, and two daughter nuclei into two daughter cells.
Note: Chromosome duplication or replication takes place in S phase while the division of the replicated chromosomes takes place in M phase.
<span>The question is asking us to choose the order of increasing complexity and the correct answer is
(3) organelles → cells → tissues → organs. Organelles are parts of cells, for example a mitochondrium is an organelle. Many cells form tissues and tissues form an organ. Many organ for an organism, for example, a human being is an organism - that's the whole animal or plant. </span>
Insulin is a hormone that controls blood glucose (sugar) levels by signaling the liver and muscle and fat cells to take in glucose from the blood. Insulin therefore helps cells to take in glucose to be used for energy. If the body has sufficient energy, insulin signals the liver to take up glucose and store it as glycogen.
