What interactions are occurring that allow the water to move against gravity in capillary action? Select three options.
solniwko [45]

Answer:

Adhesion and surface tension

Explanation:

Capillary action is the tendency of a liquid to rise or fall in a narrow tube. Two main terms are required to explain capillary action; adhesion and cohesion.

Cohesion is the force of attraction between molecules of the same kind while adhesion is the force of attraction between molecules of different kinds.

Forces of adhesion causes water to move up in a capillary tube. The water is held as it rises by surface tension forces acting on the circumference of the meniscus. The water keeps rising in the tube until the weight of the water drawn up in the tube balances the surface tension acting at the top column of the water.

If a dna analysis reveals that a cell has 60 ng of adenine and 20 ng of cytosine, how much thymine and guanine are in the cell?
Serggg [28]

Answer:

Thymine= 60 ng

Guanine= 20 ng

The complementary base pairing occurs between adenine and thymine and guanine and cytosine bases.

Explanation:

According to the Chargaff rule, a double-helical DNA molecule has an equal number or equal amount of adenine and thymine bases since adenine always pairs with thymine. Similarly, the amount of guanine base is equal to that of the cytosine base.

Chargaff rule is based on the complementary base pairing between purine and pyrimidine bases. According to the given information, the amount of adenine is 60 ng. Therefore, the cell would have 60 ng thymine. Similarly, the amount of the cytosine base in the cell is 20 ng which means that the cell would have 20 ng of guanine base.

Compare and contrast serine proteases and aspartic proteases by completing the phrases. drag each answer to the appropriate blan
8_murik_8 [283]

Answer:

read the explanation.

Explanation:

Both are enzymes, both has active sites because they are enzymes. A difference is that serine proteases has serine aminoacids in it active site. The aspartic proteases has an activated water molecule bond to one or more aspartate aminoacid in its active site.

Serine proteases are two main kinds, chymotrypsin and subtilisin kind. Aspartic proteases are three main kinds, pepsin, cathepsin and renins.

Serine proteases are found either in eukaryotes and prokaryotes, meanwhile the aspartic proteases are found mainly in eukaryotes as molds and yeast but rarely in prokaryotes such as bacteria.

Hope this info is useful.
