1 answer:

3 0

Neutrophils component is deficient in a child who has a congenital immunodeficiency that impairs <u>B lymphocyte</u> function.

Neutrophils- A specific kind of white blood cell that aids in the body's defense against infection and is crucial to the immune system. White blood cells are one of the initial immune cells to react when bacteria or viruses enter the body.

B Lymphocytes- By generating antibodies, B cells are essential for pathogen-specific immunity. Immunoglobulins attached to the surface of B lymphocytes allow them to identify soluble antigens, causing them to develop into plasma cells, which can secrete immunoglobulins and produce antibodies. Primary lymphoid tissues include lymphocytes.

Which plants produce leaves? (Select all that apply.) a. Gametophytes of bryophytes b. Gametophytes of seedless vascular plants

bixtya [17]

Answer:

a. Gametophytes of bryophytes

d. Sporophytes of seedless vascular plants

Explanation:

Bryophytes are non-vascular plants. The plant body is haploid gametophyte which is its dominant phase and bears sex organs. The gametophyte may be leafy as in moss and may be with thalloid as in liverworts.

Pteridophytes are seedless, true vascular plants. The plant body is the diploid sporophyte. The sporophyte is differentiated into true leaves, stem and roots.

This DNA molecule is replicating - write a complimentary strand to this template TAC GGG CAG CAT AAA ATC

Firdavs [7]

Answer: The complimentary strand will read ATG CCC GTC GTA TTT TAG

Explanation:

The complimentary strand to the replicating DNA molecule is known as messenger RNA (mRNA).

The mRNA directs specific bases to pair the existing base on the replicating DNA strand:

- Adenine (A) pairs only with Thymine (T)

- Guanine (G) pairs only with Cytosine (C)

So, to obtain the complimentary strand of TAC GGG CAG CAT AAA ATC, substitute each letter with its base pair.

Thus, the complimentary strand will read ATG CCC GTC GTA TTT TAG
