From left to right, which is the sequence of the<br> complementary strand of DNA in this molecule?
ladessa [460]

Answer: Option A) A-C-T-T-G

Explanation:

The base sequence on a strand of DNA is usually paired to specific complimentary bases. These specific pairings are as follows:

Adenine (A) pairs with Thymine (T)

Guanine (G) pairs with Cytosine (C). So when you find A replace with T, so also replace C with G and vice versa.

Thus, the complimentary sequence of the T-G-A-A-C DNA strand is A-C-T-T-G

Rina8888 [55]

Answer:

Adaptive defenses include both humoral and cellular immunity.

Explanation:

The innate immune response is the non-specific immune response and serves to provide an immediate and general immune response. The adaptive immune responses are the specific immune responses. Adaptive immune responses include cell-mediated immunity and antibody-mediated immunity.

Cell-mediated immunity includes T cells (cytotoxic and helper T cells) while antibody-mediated immunity includes the production of antibodies from B cells. Binding of antigen to B cells is followed by their transformation into plasma cells and produce antibodies. Some of the activated B cells form memory B cells that are responsible for quicker and strong secondary immune responses.

How does pH affect cells and cellular processes
wel
The slightest change in pH can destroy the substance or organism. The pH of a cell's interior helps regulate the cell's chemical reactions. For example, the pH of blood is 7.4, if blood falls to 6.8 or lower or 8.2 or higher, it results in death.
