Answer:
When the cell cycle is interrupted, apoptosis occurs.
Explanation:
Opoptosis is also known as programmed death of the abnormal cell. When cell DNA is damaged first it is repaired. If cell DNA cannot be repaired so the cell kill itself. If Opoptosis didn't occurs, then the cell divides with the damage DNA and transfer that damage DNA to the daughter cells which lead to cancer disease. Cancer also occurs when uncontrolled division of cells is done.
Answer:Conservation biologists, philosophers, environmental ethicists, and others offer several key reasons to conserve biodiversity. One argument is that organisms have direct economic value for humans. We use plants and animals for medicines, food, clothes, building materials, recreation, and other luxuries and necessities. But what if an organism that is of no use to us for food or hides is screened for useful medicinal compounds and found to have none? Do we sanction its extermination? Why must a plant or animal be of direct economic benefit to humans to have worth? Economic value alone is not the only reason to preserve biodiversity.
Another reason often given…to conserve biodiversity is that organisms, as components of ecosystems, provide services, and their interactions with other organisms contribute to the overall healthy functioning of ecosystems… On a practical level, biologists want to know just how much the loss of a few species will reduce the quality of services within a specific ecosystem. Two schools of thought prevail.
Answer: Option B. Cytoplasm
Explanation:
Cellular respiration is defined as the process in which sugar break down take place into as form and utilized by cell in the form of energy. In Cellular respiration food is utilized to create ATP and further used as energy source by using oxygen, and named aerobic respiration
There are four stages of cellular respiration includes first is glycolysis, second is pyruvate oxidation, third is citric acid cycle, and forth is oxidative phosphorylation.
Glycolysis is the first stage of cellular respiration which takes place in cytoplasm or cytosol.
In the process of Glycolysis six-carbon sugar undergo chemical changes and converted into two pyruvates, each containing three-carbon organic molecule. ATP and NADH are formed in this reaction.
Hence, the process take place in cytoplasm.
Considering the multiple choice;
A. Require the correct external signal to replace
B. Start to develop new receptors in adaptation to their new environment.
C. Differentiate non-randomly only when specific hormones are present.
D. develop receptors in a random fashion.
Answer;
A. Require the correct external signal to replace
If only the deterministic hypothesis is correct, undifferentiated stem cells isolated from bone marrow and grown in vitro will
Embryonic stem cells (ESCs) are stem cells derived from the undifferentiated inner mass cells of a human embryo.
Embryonic stem cells are pluripotent, meaning they are able to grow, into all derivatives of the three primary germ layers: ectoderm, endoderm and mesoderm.
Has reached it's tipping point, I think. Your question was not very specific, so hope this helps.
