Answer the following question given this paragraph: A desmosome is a cell junction specialized for cell-to-cell adhesion. They are found in simple and stratified squamous epithelium, and in muscle tissue where they bind muscle cells to one another. These junctions are composed of complexes of cell surface adhesion proteins and linking proteins. These proteins have both an intracellular and extracellular region. Inside the cell, they attach to intracellular filaments of the cytoskeleton. Outside the cell, they attach to other adhesion proteins. Q: Where are the desmosome found in a cell? A:
OPTIONS:
- epithelial
- neuron
- coating
- epithelium

Answer: epithelium

Question: Answer the following question given this paragraph: Hypersensitivities Maladaptive immune responses toward harmless foreign substances or self antigens that occur after tissue sensitization are termed hypersensitivities. The types of hypersensitivities include immediate, delayed, and autoimmunity. A large proportion of the population is affected by one or more types of hypersensitivity. Allergies The immune reaction that results from immediate hypersensitivities in which an antibody-mediated immune response occurs within minutes of exposure to a harmless antigen is called an allergy. In the United States, 20 percent of the population exhibits symptoms of allergy or asthma, whereas 55 percent test positive against one or more allergens. Upon initial exposure to a potential allergen, an allergic individual synthesizes antibodies of the IgE class via the typical process of APCs presenting processed antigen to TH cells that stimulate B cells to produce IgE. This class of antibodies also mediates the immune response to parasitic worms. The constant domain of the IgE molecules interact with mast cells embedded in connective tissues. This process primes, or sensitizes, the tissue. Upon subsequent exposure to the same allergen, IgE molecules on mast cells bind the antigen via their variable domains and stimulate the mast cell to release the modified amino acids histamine and serotonin; these chemical mediators then recruit eosinophils which mediate allergic responses. Figure 42.26 shows an example of an allergic response to ragweed pollen. The effects of an allergic reaction range from mild. Q: Hypersensitivity may refer to a maladaptive response of what system toward a harmless foreign substance? A:
OPTIONS:
- oxygen
- brain
- System
- immune
Answer: immune

input with options: Answer the following question given this paragraph: 20.2 Alcohols and Ethers Many organic compounds that are not hydrocarbons can be thought of as derivatives of hydrocarbons. A hydrocarbon derivative can be formed by replacing one or more hydrogen atoms of a hydrocarbon by a functional group, which contains at least one atom of an element other than carbon or hydrogen. The properties of hydrocarbon derivatives are determined largely by the functional group. The OH group is the functional group of an alcohol. The ROR group is the functional group of an ether. 20.3 Aldehydes, Ketones, Carboxylic Acids, and Esters Functional groups related to the carbonyl group include the CHO group of an aldehyde, the CO group of a ketone, the CO2H group of a carboxylic acid, and the CO2R group of an ester. The carbonyl group, a carbon-oxygen double bond, is the key structure in these classes of organic molecules: Aldehydes contain at least one hydrogen atom attached to the carbonyl carbon atom, ketones contain two carbon groups attached to the carbonyl carbon atom, carboxylic acids contain a hydroxyl group attached to the carbonyl carbon atom, and esters contain an oxygen atom attached to another carbon group connected to the carbonyl carbon atom. All of these compounds contain oxidized carbon atoms relative to the carbon atom of an alcohol group. 20.4 Amines and Amides The addition of nitrogen into an organic framework leads to two families of molecules. Compounds containing a nitrogen atom bonded in a hydrocarbon framework are classified as amines. Compounds that have a nitrogen atom bonded to one side of a carbonyl group are classified as amides. Amines are a basic functional group. Amines and carboxylic acids can combine in a condensation reaction to form amides. Q: Compounds containing an atom of what element, bonded in a hydrocarbon framework, are classified as amines? A:
OPTIONS:
- oxygen
- hydrogen
- ammonia
- nitrogen
output: nitrogen

Q: Answer the following question given this paragraph: Q: The diagnosis of a disease or condition before the baby is born is called? A:

OPTIONS:
- immature diagnosis
- specialized diagnosis
- specific diaganosis
- prenatal diagnosis

A: prenatal diagnosis

input: OPTIONS:
- zygote
- sperm cell
- ova
- pollen grain Now, answer this question: Answer the following question given this paragraph: Within the microsporangium, the microspore mother cell divides by meiosis to give rise to four microspores, each of which will ultimately form a pollen grain (Figure 32.7). An inner layer of cells, known as the tapetum, provides nutrition to the developing microspores and contributes key components to the pollen wall. Mature pollen grains contain two cells: a generative cell and a pollen tube cell. The generative cell is contained within the larger pollen tube cell. Upon germination, the tube cell forms the pollen tube through which the generative cell migrates to enter the ovary. During its transit inside the pollen tube, the generative cell divides to form two male gametes (sperm cells). Upon maturity, the microsporangia burst, releasing the pollen grains from the anther. Q: Within the microsporangium, the microspore mother cell divides by meiosis to give rise to four microspores, each of which will ultimately form this? A:
A:
output: pollen grain
