Answer: D. protection against a recent infection or disease is needed immediately

Explanation:

Passive immunisation is used when there is a high risk of infection and there is insufficient time for the body to build its own immune response or to mitigate the effects of active or immunosuppressive diseases.

Passive immunisation may be offered when people are unable to synthesise antibodies and when they have been exposed to a disease to which they have no protection. example of passive immunotherapy include monoclonal antibodies (MABs) or magic bullets which targets cancerous cells.

Hence, the correct option is D.

How are epimysium, perimysium, and endomysium interrelated? group of answer choices'
My name is Ann [436]

Entire muscles are encased in the epimysium. The perimysium, which is connected to the epimysium, separates groups of muscle fibres into fasciculi. Individual muscle fibres are encircled by a delicate network of connective tissue fibres, blood arteries, lymphatic vessels, and nerves called the endomysium.

The collagen fibres of tendons are made of endomysium, perimysium, and epimysium, and they serve as the tissue link between muscles and bones by indirect attachment. Intermittent perimysial junction plates serve as its connection to the perimysium.

The perimysium, which surrounds bundles of muscle fibres, the endomysium, which surrounds individual muscle fibres, and the epimysium, which surrounds the muscle, are the three scale levels at which connective tissue of the muscle may be identified.
