- er cell receptors
- b cell receptors
Q: Answer the following question given this paragraph: Figure 42.13 B cell receptors are embedded in the membranes of B cells and bind a variety of antigens through their variable regions. The signal transduction region transfers the signal into the cell. Q: What are embedded in the membranes of b cells and bind a variety of antigens through their variable regions? A:
Answer: b cell receptors

Problem:OPTIONS:
- fibroblasts
- ribosomes
- nuclei
- chloroplasts

Answer the following question given this paragraph: Chloroplasts capture light energy from the sun and use it with water and carbon dioxide to produce sugars for food. Chloroplasts look like flat discs and are usually 2 to 10 micrometers in diameter and 1 micrometer thick. A model of a chloroplast is shown in Figure below . The chloroplast is enclosed by an inner and an outer phospholipid membrane. Between these two layers is the intermembrane space. The fluid within the chloroplast is called the stroma , and it contains one or more molecules of small, circular DNA. The stroma also has ribosomes. Within the stroma are stacks of thylakoids , sub-organelles that are the site of photosynthesis. The thylakoids are arranged in stacks called grana (singular: granum). A thylakoid has a flattened disk shape. Inside it is an empty area called the thylakoid space or lumen. Photosynthesis takes place on the thylakoid membrane. Q: What cell structures capture light energy from the sun and use it with water and carbon dioxide to produce sugars for food? A:
****
A: chloroplasts

Answer the following question given this paragraph: The troposphere is the lowest layer of the atmosphere. All of the air you breathe is in the troposphere. All of Earth's weatherwind, rain, snow, heatis in the troposphere. The troposphere is the lowest and most important layer of the atmosphere!. Q: What is the lowest layer of the atmosphere? A:
OPTIONS:
- ionosphere
- chromosphere
- lithosphere
- troposphere
troposphere

Answer the following question given this paragraph: 1. The first step in eukaryotic cell division, as it is in prokaryotic cell division, is DNA replication. As you can see in Figure below , each chromosome then consists of two identical copies. The two copies are called sister chromatids. They are attached to each other at a point called the centromere. Q: Dna replication is the first step in what process for both eukaryotic and prokaryotic cells? A:
OPTIONS:
- cell death
- cell growth
- cell transfer
- cell division

Answer: cell division

Question: Answer the following question given this paragraph: The Prokaryotic Cell Recall that prokaryotes (Figure 22.10) are unicellular organisms that lack organelles or other internal membrane-bound structures. Therefore, they do not have a nucleus but instead generally have a single chromosomea piece of circular, double-stranded DNA located in an area of the cell called the nucleoid. Most prokaryotes have a cell wall outside the plasma membrane. Q: Prokaryotic cells do not have a nucleus but instead generally have a single chromosome, a piece of double-stranded dna located in an area of the cell called the what? A:
OPTIONS:
- lysosome
- cytoplasm
- spicule
- nucleoid
Answer: nucleoid

input: OPTIONS:
- bacterium
- mammal
- amphibian
