Why do scientists believe that there used to be a single continent, and what was it called?

Answers


Because they started finding the same fossils across the world and if you connected all the continents together it will form pangea.

Answer:

Because all the continents today can fit together almost perfectly, and there is also so much evidence to it. It was called Pangaea.

Proteases and acrosin are enzymes. How do they function in reproduction? A Their function is unknown. B They direct the sperm to the egg through chemical messengers. C They neutralize the mucous secretions of the uterine mucosa. D They act to break down the protective barriers around the egg, allowing the sperm

Answers

Answer: D. They act to break down the protective barriers around the egg, allowing the sperm.

Explanation:

Acrosin and other protease enzymes functions by the catalyzing the proteolysis, that is the breakdown of proteins into small polypeptides by cleaving the peptide bonds within the proteins by the process of hydrolysis.

The acrosine and other protease enzymes are released by the acrosome cap of the spermatozoa. This process facilitates the enzymatic digestion of zona pellucida layer of the egg. This helps in the penetration of egg by the sperm.

The spindle apparatus disintegrates during anaphase. true. false

Answers

The answer is true. In cell science, the shaft contraption alludes to the cytoskeletal structure of eukaryotic cells that structures amid cell division to separate sister chromatids between little girl cells. It divides the eukaryotic cells. I hope the answer will help you.
It is false that the spindle apparatus disintegrates during anaphase. The spindle apparatus disintegrates during the telophase of mitosis. This is the final phase of cell division, in this phase chromosomes move to opposite ends of the cell and two nuclei are formed.

The triplet code can produce 64 possible codon combinations. What is an advantage of this? A. Every single codon specifies more than one amino acid. / B. Every single amino acid has more than one codon. / C. The first two bases of the codon specify the amino acid.

Answers

The answer is B. Every single amino acid has more than one codon.


There are 20 different amino acids, but there are more than 20 combinations of three nucleotide bases on DNA. There are 64 different combinations of three nucleotide bases on DNA, which is about 3 times more than the number of amino acids. Therefore, every single amino acid has more than one codon is the right answer. But, it should be taken into consideration, that 2 out of 20 different amino acids have only one codon - methionine and tryptophan.

Some sea anemones can produce large colonies by reproducing asexually, but they can also produce planktonic larvae by reproducing sexually. predict the circumstances under which asexual reproduction would be favored.

Answers

I believe that the answer to the question provided above is Fission, Only prokaryotes (the archaea and the bacteria) reproduce asexually through binary fission. Eukaryotes (such as protists and unicellular fungi) may reproduce in a functionally similar manner by mitosis; most of these are also capable of sexual reproduction.

In constructing an oligonucleotide probe based on information from a protein's sequence, one often chooses, if possible, regions of a sequence containing tryptophan or methionine residues. Why?

Answers

Answer:

As the two amino acids have only one codon, the oligonucleotide probe will have a greater specificity for the DNA which Correct precisely the sequence of the probe that matches that of the target sequence, the fewer false positives one will encounter.
