Question

1 read the sentence from the section \5. cells contain genetic material.\
cells contain dna (deoxyribonucleic acid) and rna (ribonucleic acid), the genetic information necessary for directing cellular activities.
which sentence best emphasizes what the author means by \directing cellular activities\?
(a) the x and y sex chromosomes determine sex.
(b) human cells contain 23 pairs of chromosomes (for a total of 46).
(c) nucleus — controls cell growth and reproduction.
(d) they can live anywhere from a few days to a year.
2 what limitations does the image in the section \2. there are two primary types of cells\ have that the article does not have?
(a) the image only lists one major difference between the two types of cell.
(b) the image does not provide information about how dna is stored in each type of cell.
(c) the image does not identify the function of each organelle in the diagram.
(d) the image does not include all of the possible organelles in eukaryotic cells.
3 which image included in the article best depicts the idea that genetic material is the most important component of any cell?
(a) image 1
(b) image 2
(c) image 3
(d) none of the above
4 read the sentence from the section \7. different types of cells reproduce through different methods.\
most prokaryotic cells replicate by a process called binary fission.
what does the verb
eplicate\ convey in the sentence?
(a) it conveys that cell division is controlled on a regular schedule.
(b) it conveys that this process differs depending on the type of cell.
(c) it conveys that this process often results in mutations.
(d) it conveys that the resulting cells are exact copies of the original cell.

Explanation:

1. Question 1:

• The author's idea of "directing cellular activities" is about the control and regulation of cell - related functions.
• Option A is about sex determination, which is a specific function. Option B is about the number of chromosomes. Option D is about cell lifespan. Option C, where the nucleus controls cell growth and reproduction, is a general statement about directing cellular activities as growth and reproduction are fundamental cellular activities.

1. Question 2:

• The article likely provides more detailed information. An image in the section about two primary cell types may only list one major difference (e.g., prokaryotic vs. eukaryotic cell - prokaryotes lack a nucleus). The article can elaborate on multiple differences.
• Option B: The article may mention how DNA is stored (prokaryotes - circular DNA in the cytoplasm, eukaryotes - linear DNA in the nucleus). Option C: The article can describe organelle functions. Option D: The article can list more organelles. But the most likely limitation of the image is that it only lists one major difference.

1. Question 3:

• Without seeing the images, if none of the images specifically highlight genetic material as the most important component (e.g., through labels like "DNA - the core of the cell" or something similar), then "None of the above" is a valid answer.

1. Question 4:

• "Replicate" in the context of cells means to make an exact copy. Binary fission in prokaryotes results in two daughter cells that are exact copies of the parent cell.
• Option A: There is no indication of a "regular schedule" from the word "replicate". Option B: The sentence already states "different types of cells reproduce through different methods", but "replicate" itself does not convey this. Option C: There is no mention of mutations from the word "replicate".

Answer:

1. C. Nucleus — controls cell growth and reproduction.
2. A. The image only lists one major difference between the two types of cell.
3. D. None of the above
4. D. It conveys that the resulting cells are exact copies of the original cell.
