what is cell differentiation?

Answers

Answer:

The process through which a cell transforms from one cell type to another is known as cellular differentiation. In most cases, the cell transforms into a more specialized form. As a multicellular organism develops from a basic zygote to a complex system of tissues and cell types, it undergoes many stages of differentiation.

When plasma Ca concentration decreases... 1. Parathyroid hormone level increases 2. Parathyroid hormone level decreases 3. Ca and phosphate reabsorption increases 4. Ca and phosphate reabsorption decreases 5. Ca reabsorption decreases and phosphate reabsorption increases 6. Ca reabsorption increases and phosphate reabsorption decreases

Answers

Answer:

2. Parathyroid hormone level decreases

4. Ca and phosphate reabsorption decreases

Explanation:

When plasma Ca concentration decreases, the action of Parathyroid hormone level decreases  which leads to Calcium and phosphate reabsorption decreases. Parathyroid hormone is responsible for the increase of calcium and phosphorus in the blood when there is low level in the blood so when the re is huge amount of calcium and phosphorus in the blood, the Parathyroid hormone activity decreases which decrease the reabsorption of calcium and phosphorus decreases.

Important steps in sequencing pure proteins include all of these except: a. Determining the amino acids on the ends of the smaller peptides b. Determining the isoionic pH of the protein c. Determining the amino acids on the ends of the protein d. Breaking the protein into smaller peptides e. Determining the amino acid composition

Answers

Answer:

b. Determining the isoionic pH of the protein

Explanation:

The sequencing of pure proteins is nothing more than the analysis of the amino acids present in isolated proteins. This analysis is composed by the study of the sequence that the amino acids assume within the protein, the amino acids present in the extremities and the constitution of each one of these amino acids. In summary, we can state that protein sequencing refers to the constitution of these proteins. In this case, the isotonic pH of these proteins is not relevant information.

Ideas aimed at explaining how organisms change, or evolve, over time date back to Anaximander of Miletus, a Greek philosopher who lived in the 500s B.C.E. Noting that human babies are born helpless, Anaximander speculated that humans must have descended from some other type of creature whose young could survive without any help. He concluded that those ancestors must be fish, since fish hatch from eggs and immediately begin living with no help from their parents. From this reasoning, he proposed that all life began in the sea.

Answer:

A zygote is a eukaryotic cell that is produced when two gametes fertilize each other. The genome of a zygote is made up of the DNA from each gamete and includes all of the genetic information needed to create a new person.

what is menstruation and why does it occurs​

Answers

Answer:

A period happens because of changes in hormones in the frame. Hormones are chemical messengers. The ovaries launch the lady hormones estrogen and progesterone . those hormones motive the liner of the uterus (or womb) to build up. The constructed-up lining is prepared for a fertilized egg to connect to and begin developing. If there is no fertilized egg, the liner breaks down and bleeds. Then the identical manner occurs all once more.

 

It normally takes about a month for the liner to build up, then smash down. this is why a lot of ladies and women get their periods round once a month.

What statements are true about glycolysis?
Select all that apply.
it consumes some ATP as well as producing it
it produces ATP that can be directly used by cells
o it does not directly require oxygen to operate
o it produces more ATP than any of the other respiration reactions

Answers

Answer:

 true it consumes some ATP as well as producing it

true it produces ATP that can be directly used by cells

true it does not directly require oxygen to operate

false it produces more ATP than any of the other respiration reactions

Glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.

What is ATP?

ATP stands for adenosine triphosphate. It is defined as an organic substance that fuels a variety of functions in living cells, including chemical synthesis, condensate dissolution, nerve impulse transmission, and muscular contraction. It is a byproduct of the photophosphorylation, cellular respiration, and fermentation processes and serves as the primary energy currency of the cell.

Glycolysis is defined as a chain of events that convert glucose into two pyruvate molecules, which have three carbons each. Glycolysis is a cytoplasmic process that breaks glucose down into two molecules with three carbons apiece and releases energy. Hexokinase, a phosphorylating enzyme, assists in the phosphorylation process that traps glucose.

Thus, glycolysis consumes some ATP as well as producing it, it produces ATP that can be directly used by cells and it does not directly require oxygen to operate. Hence option A,B and C is correct.

Whiteflies are common pest insects found on cotton, tomato, poinsettia, and many other plants. Nymphs are translucent and mostly sessile, feeding on their host plant's phloem (sap) from the undersides of leaves. They undergo incomplete metamorphosis into winged adults. Because whitefly nymphs cannot escape predation by moving, you hypothesize that their translucent bodies make them hard to spot by predators. How could you directly test this hypothesis?

Answers

Answer: Comparing the rates of predation on whitefly nymphs coated with a nontoxic dye versus the undyed whitefly nymphs.

Explanation:

A hypothesis refers to an assumption, which is proposed for the sake of an argument which is tested to ascertain if it's true.
