to aid in adhering to the cells environment
to aid in preventing phagocytosis from cells that might engulf the bacterium

question 18 (1 point) saved
the nucleoid contains
chromosomal material.
peptidoglycan.
actin.
a membrane.

Explanation:

• Question 16: Red tide is mainly caused by a bloom of dinoflagellates (a type of algae, not protozoans).
• Question 17: The glycocalyx helps cells adhere to their environment, can prevent phagocytosis (e.g., in some bacteria), and is involved in biofilm formation.
• Question 18: The nucleoid is the region in prokaryotic cells that contains the chromosomal DNA (chromosomal material). Peptidoglycan is in the cell wall of bacteria, actin is a eukaryotic cytoskeletal protein, and the nucleoid is not membrane - bound.

Answer:

• Question 16: False
• Question 17: all of the above
• Question 18: chromosomal material.
