A macrophage may engulf a pathogen by endocytosis, which involves the reorganization of actin microfilaments in the membrane and microtubules in the cytoskeleton.
<h3>What is endocytosis?</h3>
Endocytosis is a cellular process by which a cell can absorb materials from the surrounding medium, such as viruses and bacteria in the case of macrophages.
Microfilaments and microtubules are proteins that form part of the cytoskeleton and dynamic conformational changes of them are associated with the cytoskeletal rearregement during the phagocytic process.
The actin microfilaments in the membrane and microtubules in the cytoskeleton form part of the process of endocytosis because they need to reorganize during cell movement.
In conclusion, a macrophage may engulf a pathogen by endocytosis, which involves the reorganization of actin microfilaments in the membrane and microtubules in the cytoskeleton.

Answer: Arenite
Explanation:
Arenite can be defined as the sedimentary clastic rock.
It is of the sand grain size.
It also comprises of matrix.
It is a metamorphosed sediment.
Arenite is formed by the erosion of the turbiditic re-deposition of the sands. It belongs to silicatic limestones.
Answer:
The correct answer will be- epimysium
Explanation:
Epimysium is the fibrous connective tissue envelope which surrounds the muscle fibers of the muscle as a whole.
The epimysium plays an important role in maintaining the muscle structure as it protects the muscle from the friction caused by the associated bones and the muscles.
The epimysium is continuous with other layers called the endomysium, perimysium, tendons and the fascia.
Thus, epimysium is the correct answers.
