Passive transport involves movement of substances

Biology
1 answer:
gtnhenbr [62]3 years ago
5 0

Answer:

Passive transport involves movement of substances from areas of higher concentration to areas of lower concentration.

Explanation:

Passive transport involves the passage of substances through a semi-permeable membrane, as occurs with transport at the level of cell membranes.

Generally, passive transport occurs with the <u>movement of compounds from the space with the highest concentration of a specific substance to the space with the lowest concentration of the same substance</u>, following the so-called concentration gradient. Theoretically, the gradient tends to disappear when the concentrations of substances have balanced out.

Regarding other options:

<em>     A. </em><u><em>From areas of lower concentration to areas of higher concentration</em></u><em>.  It is a feature of active transport.</em>

<em>      C. </em><u><em>From areas in which the concentration has reached a balance</em></u><em>.  There is no passive transport</em>

<em>      D. </em><u><em>From areas of differing concentrations with the use of cellular energy</em></u><em>.  Energy use involves active transport.</em>

How a mutation in the DNA could affect the proteins made by the cell
julia-pushkina [17]

A mutation in DNA affects the entire protiens synthesis process by producing the incorrect amino acids in the wrong places, causing issues with the ability of the organism to survive depending on what the protein is in charge of.

AUGGCGUUU which of the following DNA strands could have been the template for this RNA?
Delvig [45]

Answer:

3' TACCGCAAA 5'

Explanation:

Transcription is the process by which a particular DNA sequence (e.g., a gene) is used as a template to synthesize a complementary RNA sequence that grows in a 5′ → 3′ direction. This RNA molecule is usually a messenger RNA (mRNA) which is then used to synthesize a polypeptide chain (i.e., a protein) by a process called translation. The complementary RNA molecule produced during transcription is synthesized according to the base pair rules, i.e., Adenine (A) bases always pair with Thymine (T) bases, while Guanine (G) bases always pairs with Cytosine (C) bases. In RNA, Uracil (U) bases pair with adenine, thereby replacing thymines during transcription.
