Juliette [100K]

The correct answer is that the shells of clams and other mollusks dissolve when the pH becomes more acidic.

This is because the shells of clams and other mollusks are made of calcium carbonate that is dissolved in acidic conditions. The pH  needs to be low to dissolve calcium carbonate into it. It takes few days to dissolve the shell completely.

HELP WORTHA FREE BRAINLY IF RIGHT
zalisa [80]

Answer: The answers seem correct.

1. Active transport - the process in which energy is used to move the particles of a substance against a concentration gradient from a region where they are in lower concentration to a region whey are in higher concentration.

2. The answer chosen for #2 makes sense because energy is usually needed when you putting effort into doing an activity that includes some type of force. That means ions are using energy to be moved against the concentration gradient.

3. Volume makes sense for the last question since the cells are using a space (volume) to move material in and out by diffusion. The other options besides volume are unreasonable.

What is the difference between bracketed key and indented key?​
____ [38]

Answer:

<em>Bracketed and indented keys are two dichotomous/or branching keys with an ordered, numbered couplet, and spatially differentiated respectively.</em>

Explanation:

Dichotomous keys are used in the identification and classification of taxa.

Bracketed keys, or parallel keys, are easy to understand- for efficiency, these keep the first two entries of every couplet or pair being compared. It also makes use of a numbering system in the couplet choices for easy tracking.

Indented keys maintain an equal distance from the margin on the left of the pages. Successive couplets are indented til the taxon is identified.
