The cell is taking in substances through membrane proteins, without any energy expenditure of its own. The substances naturally

follow their concentration gradient. However, they must go through the protein channels, because they are too large to squeeze through the cell membrane. This process is called

The right answer is facilitated diffusion.

Facilitated diffusion is a diffusion mechanism facilitated by membrane transporters. it's the spontaneous passage of molecules or ions (like the passive diffusion) through a biological membrane through transport molecules (unlike passive diffusion). This process does not consume energy (like the passive diffusion) and therefore does not involve active transportation.

Facilitated diffusion. because the protein channels must help the substance get into the cell based on fitting. It's important to regulating what comes in and goes out.

A student builds a model of a DNA strand.
insens350 [35]

Answer:

There is no attachment to this question, however, the base sequence on the model built by the student is: CAGCCATC

The options of the bases on the complementary model are:

A) CTACCGAC

B) GUCGGUAG

C) GTCGGAAG

D) GTCGGTAG

The answer is D

Explanation:

A DNA molecule is a polymer biomolecule made up of nucleotide bases. It is a double stranded molecule, with each strand containing nucleotides held together by hydrogen bonds. The pairing of nucleotides in one strand of DNA to another follows the COMPLEMENTARY BASE PAIRING RULE, which states that Adenine binds to Thymine (A-T) while Guanine binds to Cytosine (G-C).

According to this question, a student builds a model containing the base sequence: CAGCCATC, the model that contains bases that are complementary to the ones built by the student is: GTCGGTAG
