Q: Ringworm and athlete's foot are human diseases caused by what simple organisms? Read this paragraph and choose the correct option from the provided answers: Fungi are simple eukaryotic organisms that consist of one or more cells. They include mushrooms and yeasts. Human diseases caused by fungi include ringworm and athlete's foot. Both are skin diseases that are not usually serious. A ringworm infection is pictured below ( Figure below ). A more serious fungus disease is histoplasmosis. It is a lung infection. Though fungal infections can be annoying, they are rarely as serious or deadly as bacterial or viral infections. Choices: - bacteria - insects - viruses - fungi A:
fungi

Q: The minimum amount necessary for self-sustained fission of a given nuclide is called what? Read this paragraph and choose the correct option from the provided answers: Not every neutron produced by fission induces fission. Some neutrons escape the fissionable material, while others interact with a nucleus without making it fission. We can enhance the number of fissions produced by neutrons by having a large amount of fissionable material. The minimum amount necessary for self-sustained fission of a given nuclide is called its critical mass. Choices: - its half-life - its molar mass - its activation energy - its critical mass A:
(Answer)
its critical mass

Ques: Q: Genetic disorders are diseases caused by what? Read this paragraph and choose the correct option from the provided answers: Sequencing the human genome has increased our knowledge of genetic disorders. Genetic disorders are diseases caused by mutations. Many genetic disorders are caused by mutations in a single gene. Others are caused by abnormal numbers of chromosomes. Choices: - lesions - environment - traits - mutations A:
Ans: mutations

(Q).
Q: What is the simplest type of carbon-based compounds? Read this paragraph and choose the correct option from the provided answers: Hydrocarbons are compounds that contain only carbon and hydrogen. Hydrocarbons are the simplest type of carbon-based compounds. Nonetheless, they can vary greatly in size. The smallest hydrocarbons have just one or two carbon atoms, but large hydrocarbons may have hundreds. The size of hydrocarbon molecules influences their properties. For example, it influences their boiling and melting points. As a result, some hydrocarbons are gases at room temperature, while others are liquids or solids. Hydrocarbons are generally nonpolar and do not dissolve in water. In fact, they tend to repel water. That's why they are used in floor wax and similar products. Choices: - Buckminsterfullerine - graphite - particles - hydrocarbons A:
(A).
hydrocarbons

Ques:Q: What types of stimuli control endocrine activity? Read this paragraph and choose the correct option from the provided answers: Role of Endocrine Gland Stimuli Reflexes triggered by both chemical and neural stimuli control endocrine activity. These reflexes may be simple, involving only one hormone response, or they may be more complex and involve many hormones, as is the case with the hypothalamic control of various anterior pituitarycontrolled hormones. Humoral stimuli are changes in blood levels of non-hormone chemicals, such as nutrients or ions, which cause the release or inhibition of a hormone to, in turn, maintain homeostasis. For example, osmoreceptors in the hypothalamus detect changes in blood osmolarity (the concentration of solutes in the blood plasma). If blood osmolarity is too high, meaning that the blood is not dilute enough, osmoreceptors signal the hypothalamus to release ADH. The hormone causes the kidneys to reabsorb more water and reduce the volume of urine produced. This reabsorption causes a reduction of the osmolarity of the blood, diluting the blood to the appropriate level. The regulation of blood glucose is another example. High blood glucose levels cause the release of insulin from the pancreas, which increases glucose uptake by cells and liver storage of glucose as glycogen. An endocrine gland may also secrete a hormone in response to the presence of another hormone produced by a different endocrine gland. Such hormonal stimuli often involve the hypothalamus, which produces releasing and inhibiting hormones that control the secretion of a variety of pituitary hormones. In addition to these chemical signals, hormones can also be released in response to neural stimuli. A common example of neural stimuli is the activation of the fight-or-flight response by the sympathetic nervous system. When an individual perceives danger, sympathetic neurons signal the adrenal glands to secrete norepinephrine and epinephrine. The two. Choices: - light and pressure - temperature and light - pressure and chemical - chemical and neural A:

Ans:chemical and neural

Q: Solutions to schrodinger's equation involve four special numbers called what? Read this paragraph and choose the correct option from the provided answers: Solutions to Schrodinger's equation involve four special numbers called quantum numbers . (Three of the numbers, , , and , come from Schrodinger's equation, and the fourth one comes from an extension of the theory). These four numbers completely describe the energy of an electron. Each electron has exactly four quantum numbers, and no two electrons have the same four numbers. The statement that no two electrons can have the same four quantum numbers is known as the Pauli exclusion principle . Choices: - gravity numbers - linear numbers - light numbers - quantum numbers A:
quantum numbers
