A white blood cell engulfing foreign materials is more likely to carry out Endocytosis.
Explanation:
- Endocytosis is the process by which a cell takes up a macromolecule into is cytoplasm by forming a vessicle.
- In the question two cases are given, both the cases involve the formation of membrane bound vessicle but in different ways.
- The excretion of hormones involves the movement of molecule outside the cytoplasm. This process is exocytosis.
- The engulfment of an antigen by WBC involves taking up of molecule within the cell so that it can be killed and digested. Thus in this case Endocytosis is more likely to occur..
Answer:
B. Bacteria can exchange genes for resistance to antibiotics in this way.
Explanation:
Even though conjugation requires cell-to-cell contact, it can occur between distantly related bacteria
Organelles exist within cells, which exist within tissues. Communities exist within ecosystems, which exist in the biosphere.
Creep is a solid material's tendency to deform permanently under pressure or stress.
