Answer 1

Answer:

Irregular galaxy

A galaxy that has an unidentified shape is best classified as an irregular galaxy.

An irregular galaxy is a galaxy that has an undefined regular shape. These galaxies are composed of large amounts of young stars, gas, and dust. Irregular galaxies are usually small, disorderly in appearance, and without a nuclear bulge or any trace of spiral arm shape. Examples of irregular galaxies are the small and large magellanic clouds.

What kind of bacterium would be most likely found in the human stomach

Enzymes - particularly proteases. These break down protein in the stomach in the presence of low pH (acidic material eg stomach acid).
In addition to this, there are many bad bacteria that cause illnesses such as E. Coli or Helicobacter Pylori

Why is it necessary to use the same restriction enzyme to cut 2 pieces of DNA that are to be joined together?

Answers

The reason why is necessary to use the same restriction enzyme is because
if we don't, the two pieces of DNA that we are trying to joint won't have matching ends and won't join properly.

To insert that gene we first cut him out from a DNA sequence(sequence 1), so To do that we use a restriction enzyme.

Meanwhile, we want to put that piece into another DNA sequence (sequence 2), so we also have to make a cut to be able to insert the gene and that will also be done with the same restriction enzyme.

This restriction enzyme needs to be the same one that cut the gene out of sequence 1. The enzyme recognizes specific sites in DNA, so when joined they will have ends that will match the gene's ends.

Each enzyme cuts a specific sequence with specific ends(that will attach to other DNA). If the two pieces of DNA are cut with different enzymes then their ends will not match up and they will not join properly.

Secretion of cholecystokinin from the intestinal wall is stimulated by

Answers

Answer:

The correct answer is: fat in the small intestine.

Explanation:

Cholecystokinin, abbreviated to CCK, is a hormone produced in the small intestine that participates in digestion. Its secretion is stimulated by fatty acids in the small intestine (more specifically, in the duodenum) and by the introduction of hydrochloric acid.

Cholecystokinin has the functions to 1) contract the gallbladder so it releases the stored bile into the intestine, and 2) stimulate the secretion of pancreatic juice, which induces satiety.

Final answer:

Cholecystokinin's secretion is primarily triggered by fatty acids and specific amino acids in the small intestine, aiding in their digestion through the release of bile from the gallbladder and enzymes from the pancreas.

Explanation:

The secretion of cholecystokinin from the intestinal wall is mainly stimulated by the presence of fatty acids and certain amino acids in the small intestine's duodenum. Cholecystokinin is a vital hormone that aids in digestion. When fatty acids or certain specific amino acids, such as phenylalanine or tryptophan, enter the duodenum, they trigger the release of this hormone. This hormone then assists in the digestion of these substances by stimulating the gallbladder to release bile and the pancreas to release pancreatic enzymes.

if the united states continues using petroleum in vast amounts, it will become even more dependent on foreign sources for this resource. why?

Answers

Since we've been using petroleum in vast amounts organizations such as OPEC have appeared which restricts the U.S which ensued our country into suing; if this lawsuit passes then we will possibly be taking more petroleum than ever before due to it's demand such as it's needed for machinery and vehicles and etc. Most petroleum are from middle eastern countries, so our dependency will run rampant which will make us adhere to any of their policies pertaining to this fossil fuel in the near future.

Describe nondisjunction and the effect it can have on a human

Answers

Nondisjunction is the improper segregation of chromosomes during either meiotic or mitotic cell division.

The result of nondisjunction is dosage imbalance - either one extra or one missing chromosome for some proportion of the resulting cells.

Answer:

It is the failure of homologous chromosomes to separate properly during gamete formation (meiosis). Klinefelter syndrome can occur and is seen as males with gametes XXY instead of XY. It affects sex organs, including creating smaller testes and causing sterility. Males can be taller in stature with normal intelligence.
