To lyse foreign pathogens or ill self-cells, one can use cytotoxic T cells.
The ideal answer is B.
What is the most frequent means through which the immune system defends us against invading microbes?Antibodies. The body uses antibodies to combat microorganisms and the toxins (poisons) they create. They accomplish this by identifying molecules known as antigens that are either present on the microbe's surface or in the chemicals that it produces and brand it as a foreign substance. These antigens are then marked by the antibodies for elimination.
In bacterial cell membranes, which protein creates pores?We gave the protein the name perforin-2 on the grounds that it is a brand-new pore-forming protein. A pore-forming protein is expressed in macrophages, which suggests that it may be employed to eradicate intracellular bacteria.

the nurse need to place a dressing under and around a penrose drain. which dressing would be best for the nurse to obtain?
A pre-cut 4 x 4 sterile drain sponge would be the finest dressing to obtain if the nurse needed to apply a dressing under and around a penrose drain.
To cover the drain and the area around it, the nurse should get the pre-split drain sponge. The sterile 2 x 2 gauze sponge cannot fit beneath and around the drain because it is too small and lacks a precut split. The medicated, non-adherent petrolatum dressing gauze is not recommended.
A Penrose drain is a latex tube that is soft, flat, and flexible. It permits fluids, including blood, to exit the surgical site. This prevents fluid from accumulating beneath your surgical cut or incision and leading to an infection. You will have a portion of your Penrose drain inside of you. The second major sort of drain is "active," and this one is classified as "passive." After American gynaecologist Charles Bingham Penrose, the Penrose drain was created.

what is the substance required to cleave the vector dna during recombinant dna technology?
cleaving the DNA with a RESTRICTION ENZYME
The first step in the development of recombinant DNA technology was the characterization of restriction endonucleases.
What is DNA?
DNA, or deoxyribonucleic acid, is a complicated molecule that carries all of the information required to construct and maintain an organism. DNA is found in the cells of all living things. In fact, practically every cell in a multicellular creature contains the entirety of the organism's DNA.
However, DNA does more than just specify the structure and function of living things; it is also the primary unit of heredity in all organisms. To put it another way, when organisms reproduce, a portion of their DNA is passed down to their offspring.
DNA stores information as a code composed of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA is made up of approximately 3 billion bases, with more than 99 percent of those bases being the same in all humans. The order, or sequence, of these bases defines the information accessible for constructing and maintaining an organism, in the same way that letters of the alphabet occur in a specific order to make words and phrases.
The characterization of restriction endonucleases—enzymes that break DNA at specified sequences—was the initial step in the creation of recombinant DNA technology. These enzymes were discovered in bacteria, where they appear to protect the cell from the introduction of foreign DNA (e.g., from a virus).
