Answer and Explanation:

An acid has a pH that is less than 7.  A base has a pH that is greater than 7.  Something that has a pH of 7 is neutral, but since it doesn't seem that the question is asking about neutral, you can ignore that for this problem.

Situation 1:   Base

Situation 2:  Acid

Situation 3:  Acid

Situation 4:  Base

Situation 5:  Acid

Situation 6:  Base

A.  Water directly out of the tap has a pH of 7.2.  When you add carbon dioxide (blow into the water), you get a pH of 5.1.  This means that the addition of carbon dioxide makes water more acidic.

B.  The most basic solution will have the highest pH.  This means that it will be water with bleach added to it.

C.  The most acidic solution will have the lowest pH.  This means that it will be water with instant coffee.

anastassius [24]

Answer:

Means to increase drag and prevent sinking is the correct answer.

Explanation:

Plankton avoid sinking by increasing their surface area and decreasing their density. Spines slow down sinking by adding surface area without increasing density. Defense against predation would be to sing below. Not the opposite.

In, addition to water, what would most likely be found in a plant central vacuole?
mrs_skeptik [129]

Answer:

The correct answer would be c) food molecules.

A vacuole is a membrane-bound cell organelle present usually in the center of the plant cell.

It contains a high amount of water as it plays important role in maintaining the turgor pressure of the cell.

In addition, it contains a high amount of ions (such as K⁺, Mg²⁺, Ca²⁺), food molecules (such as glucose, sucrose, fructose), organic acids (such as malic, tartaric, quinic) and waste material.

He terms motif (fold) and domain describe levels of protein organization more complicated than primary or secondary structure. d
fenix001 [56]

The motif is the repetitive supersecondary structures, an example of a motif is a beta-alpha-beta unit. The motifs are formed of the clusters of secondary structure.  

On the other hand, the domains are globular and stable functional units in a protein. It may retain a three-dimensional configuration when distinguished from the rest of the protein.  

Both the motifs and domains are stabilized by the hydrophobic interactions, they both are a unit of tertiary structure, and are dependent on primary composition.
