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:
a. Because it offers the greatest improvement in environmental conditions, sufficient to match the damage caused by CEP, for the least expense.
Explanation:
The businesses are required to restore the land to their original condition once they are with their business activities. The business operations often causes damage to the site and nearby land, for this reason restoration is mandatory in many countries. Vancouver Fraser Port Authority selects Maplewood Flats for the restoration activity because it offers the restoration at cheap cost. This will save company's cost and the land will be to its original condition with least possible damage to environment.
<span>A unique feature of dna is that it can duplicate itself through a process called replication.</span>
<span>Decomposition reaction is where an organism undergoes breakdown into simpler molecules and compounds. This is caused by other biotic and abiotic factors in the environment. Simply, decomposition is part of a cycle where a complex compound is breakdown and used again for complex reconstruction of other organic processes. </span>
