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:
****
A: b cell receptors

Answer the following question given this paragraph: Corals form large colonies in shallow tropical water. They are confined to shallow water because they have a symbiotic relationship with algae that live inside of them. The algae need sunlight for photosynthesis, so they must stay relatively close to the surface of the water to get enough light. Corals exist only as polyps. They catch plankton with their tentacles. Q: Coral and the algae living inside of them have what type of relationship, since the algae relies on the coral to stay close to the water's surface? A:
OPTIONS:
- peculiar
- competitive
- parasitic
- symbiotic
symbiotic

Answer the following question given this paragraph: Food and Drink App: Vitamins and Minerals Vitamins are nutrients that our bodies need in small amounts but cannot synthesize; therefore, they must be obtained from the diet. The word vitamin comes from "vital amine" because it was once thought that all these compounds had an amine group (NH2) in it. This is not actually true, but the name stuck anyway. All vitamins are covalently bonded molecules. Most of them are commonly named with a letter, although all of them also have formal chemical names. Thus vitamin A is also called retinol, vitamin C is called ascorbic acid, and vitamin E is called tocopherol. There is no single vitamin B; there is a group of substances called the B complex vitamins that are all water soluble and participate in cell metabolism. If a diet is lacking in a vitamin, diseases such as scurvy or rickets develop. Luckily, all vitamins are available as supplements, so any dietary deficiency in a vitamin can be easily corrected. A mineral is any chemical element other than carbon, hydrogen, oxygen, or nitrogen that is needed by the body. Minerals that the body needs in quantity include sodium, potassium, magnesium, calcium, phosphorus, sulfur, and chlorine. Essential minerals that the body needs in tiny quantities (so-called trace elements) include manganese, iron, cobalt, nickel, copper, zinc, molybdenum, selenium, and iodine. Minerals are also obtained from the diet. Interestingly,. Q: Essential minerals that the body needs in tiny quantities are called what? A:
OPTIONS:
- flux minerals
- draw minerals
- byproduct minerals
- trace minerals

Answer: trace minerals

Question: Answer the following question given this paragraph: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects appear blurry. It occurs when the eyeball is shorter than normal (see Figure below ). This causes images to be focused in a spot that would fall behind the retina (if light could pass through the retina). Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they fall on the retina instead of behind it. Q: What is the condition in which distant objects are seen clearly, but nearby objects appear blurry? A:
OPTIONS:
- synthesise , or hyperopia
- nearsightedness or hyperopia
- gleam , or hyperopia
- farsightedness, or hyperopia
Answer: farsightedness, or hyperopia

input with options: Answer the following question given this paragraph: Root Growth and Anatomy Root growth begins with seed germination. When the plant embryo emerges from the seed, the radicle of the embryo forms the root system. The tip of the root is protected by the root cap, a structure exclusive to roots and unlike any other plant structure. The root cap is continuously replaced because it gets damaged easily as the root pushes through soil. The root tip can be divided into three zones: a zone of cell division, a zone of elongation, and a zone of maturation and differentiation (Figure 30.16). The zone of cell division is closest to the root tip; it is made up of the actively dividing cells of the root meristem. The zone of elongation is where the newly formed cells increase in length, thereby lengthening the root. Beginning at the first root hair is the zone of cell maturation where the root cells begin to differentiate into special cell types. All three zones are in the first centimeter or so of the root tip. Q: Why is the root cap continuously replaced in plants? A:
OPTIONS:
- due to growth
- due to pressure
- due to rubbing
- damage through pushing
output: damage through pushing

Problem: OPTIONS:

- land-level organization
- delicate - level organization
- organ-level organization
Q: Answer the following question given this paragraph: Roundworms have organ-level organization, in which two or more types of tissues work together to perform a particular function as an organ. For example, a roundworm has a primitive brain that controls how the organism responds to the environment. Q: Roundworms exemplify what type of organization, where two or more types of tissues work together to perform a particular function as an organ? A:
Answer:
organ-level organization
