Question

question 7 1 pts which of the following recognize and destroy nonself cells? gland cells immune cells nerve cells red blood cells question 8 1 pts which of the following is not a function of the smooth endoplasmic reticulum? provides a site for ribosome attachment supplies membrane for use throughout the cell makes steroid hormones makes glycoproteins question 9 1 pts the ____ is often called the microtubule organizing center. centrosome cytoskeleton centriole ribosome

Explanation:

• Question 7: Immune cells are part of the body's defense system and can recognize and destroy non - self cells like pathogens. Gland cells secrete substances, nerve cells transmit electrical signals, and red blood cells transport oxygen.
• Question 8: Ribosomes attach to the rough endoplasmic reticulum, not the smooth endoplasmic reticulum. The smooth endoplasmic reticulum supplies membrane, makes steroid hormones, and is involved in making glycoproteins to some extent.
• Question 9: The centrosome is often called the microtubule organizing center. The cytoskeleton provides structural support, centrioles are involved in cell division, and ribosomes are for protein synthesis.

Answer:

Question 7: B. Immune cells
Question 8: A. Provides a site for ribosome attachment
Question 9: A. centrosome
