I say it would be B. because it is the safest for you. You should never reach across a flame because of the risk of catching on fire. And never leave a flame unattended. Heating a liquid in a closed container could be dangerous as well because it heats fast and could go wrong. I hope this helps!
Answer:
A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less.
Explanation:
A cell may vary the rate of an enzyme controlled reaction by making more/less or degrading more/less. Several factors affect the rate at which enzymatic reactions proceed include post translational modifications, substrate concentration, cofactors, temperature, pH, locations. The shape and structure of the enzyme will change as the pH value of the reaction medium changes.
Answer:
The behavior of chromosomes during meiosis and fertilization is responsible for most of the variation that arises in each generation. Three mechanisms contribute to genetic variation arising from sexual reproduction: independent assortment of chromosomes, crossing over, and random fertilization.
Mitosis, a procedure of cell duplication, or multiplication, amid which one cell offers ascend to two hereditarily indistinguishable girl cells. Carefully connected, the term mitosis is utilized to depict the duplication and dissemination of chromosomes, the structures that convey the hereditary data.
A concise treatment of mitosis pursues. For a full treatment, see development: In cells; cell: Mitosis and cytokinesis.
Preceding the beginning of mitosis, the chromosomes have imitated and the proteins that will frame the mitotic axle have been incorporated. Mitosis starts at prophase with the thickening and curling of the chromosomes. The nucleolus, an adjusted structure, shrivels and vanishes. The finish of prophase is set apart by the start of the association of a gathering of strands to frame a shaft and the breaking down of the atomic layer.
The chromosomes, every one of which is a twofold structure comprising of copy chromatids, line up along the midline of the cell at metaphase. In anaphase every chromatid pair isolates into two indistinguishable chromosomes that are destroyed to inverse closures of the cell by the shaft strands. Amid telophase, the chromosomes start to decondense, the axle separates, and the atomic films and nucleoli re-structure. The cytoplasm of the mother cell partitions to frame two girl cells, each containing indistinguishable number and sort of chromosomes from the mother cell. The stage, or stage, after the consummation of mitosis is called interphase.
P.S. You're a mean person. You ought to pursue different people groups bearing and don't simply answers something for focuses. Fortunately, I revealed you and your answers got delted and afterward erased the 50 points that you escaped your focuses. Try not to do that or else no one's going to like you. Bye....
Also the image below show that I didn't copy. It says it's 100% original and i got it from paperrater.com
Answer:
Questions, hypotheses, and ideas should be tested against observable evidence.
Explanation:
Skepticism is extremely important, if not fundamental, in all areas of Science. This attitude is based on the belief that all questions, hypotheses, and ideas should be tested against observable evidence. Moreover, it allows scientists to <u>question and think thoroughly about all possibilities behind a phenomenon, instead of just 'believing' any observation or vague and non-supported reason that explains it.</u>
In addition, it allows researchers to investigate all possibilities and test numerous methodologies to be certain and gather enough evidence to explain this certain phenomenon.
