Q: When dissolved in water, what do strong acids transfer to the solvent completely? Read this paragraph and choose the correct option from the provided answers: Strong acids completely transfer their acidic protons to the solvent when dissolved in water. When a weak acid is dissolved in water, most of the molecules will retain their acidic protons, and only a small percentage will dissociate. Choices: - acidic neutrons - acidic electrons - acidic proteins - acidic protons A:
acidic protons

Q: Zeros that appear in front of all of the nonzero digits are called what? Read this paragraph and choose the correct option from the provided answers: 3. Zeros that appear in front of all of the nonzero digits are called left-end zeros. Left-end zeros are never significant. A. 0.008 has one significant figure. Choices: - zero sum game - significant digits - non-numbers - left-end zeros A:
(Answer)
left-end zeros

Ques: Q: Many diseases arise from genetic mutations that prevent the synthesis of critical what? Read this paragraph and choose the correct option from the provided answers: Geneticist Many diseases arise from genetic mutations that prevent the synthesis of critical proteins. One such disease is Lowe disease (also called oculocerebrorenal syndrome, because it affects the eyes, brain, and kidneys). In Lowe disease, there is a deficiency in an enzyme localized to the Golgi apparatus. Children with Lowe disease are born with cataracts, typically develop kidney disease after the first year of life, and may have impaired mental abilities. Lowe disease is a genetic disease caused by a mutation on the X chromosome. The X chromosome is one of the two human sex chromosome, as these chromosomes determine a person's sex. Females possess two X chromosomes while males possess one X and one Y chromosome. In females, the genes on only one of the two X chromosomes are expressed. Therefore, females who carry the Lowe disease gene on one of their X chromosomes have a 50/50 chance of having the disease. However, males only have one X chromosome and the genes on this chromosome are always expressed. Therefore, males will always have Lowe disease if their X chromosome carries the Lowe disease gene. The location of the mutated gene, as well as the locations of many other mutations that cause genetic diseases, has now been identified. Through prenatal testing, a woman can find out if the fetus she is carrying may be afflicted with one of several genetic diseases. Geneticists analyze the results of prenatal genetic tests and may counsel pregnant women on available options. They may also conduct genetic research that leads to new drugs or foods, or perform DNA analyses that are used in forensic investigations. Choices: - oils - acids - lipids - proteins A:
Ans: proteins

Q: Free ear lobes, widow's peak and a dimpled chin are examples of what kind of traits in humans? Read this paragraph and choose the correct option from the provided answers: In many instances, the relationship between genes and inheritance is more complex than that which Mendel found. Nevertheless, geneticists have since found that Mendel's findings can be applied to many organisms. For example, there are clear patterns of Mendelian inheritance in humans. These include the inheritance of normal characteristics and characteristics that occur less often. Easily observable Mendelian traits in humans include free ear lobes (in most people the ear lobes hang free (dominant), whereas the attached earlobe is recessive), hitchhiker's thumb (a straight thumb is dominant, while a bent thumb is recessive), widow's peak (a hairline with a distinct point in the middle of the forehead is dominant, while a straight hairline is recessive), dimpled chin (a cleft in the chin is dominant, whereas the absence of a cleft is recessive), and mid-digital hair (hair on any middle segments of the fingers is dominant). Of course, many severe human phenotypes are inherited in a Mendelian fashion including Phenylketonuria (PKU), cystic fibrosis, Huntington's disease, hypercholesterolemia, and sickle-cell anemia. These are termed genetic disorders and will be discussed in additional concepts. Choices: - genetic disorders - adaptations - spontaneous mutations - mendelian A:
(A).
mendelian

Ques:Q: Alkenes with the same atoms but different shapes are called what? Read this paragraph and choose the correct option from the provided answers: Alkenes can have different shapes. They can form straight chains, branched chains, or rings. Alkenes with the same atoms but different shapes are called isomers. Smaller alkenes have relatively high boiling and melting points, so they are gases at room temperature. Larger alkenes have lower boiling and melting points, so they are liquids or waxy solids at room temperature. Choices: - alcohols - monomers - isotopes - isomers A:

Ans:isomers

Q: What is a person who studies the frequency and distribution of disease within human populations and environments called? Read this paragraph and choose the correct option from the provided answers: Epidemiologist Epidemiology is the study of the occurrence, distribution, and determinants of health and disease in a population. It is, therefore, part of public health. An epidemiologist studies the frequency and distribution of diseases within human populations and environments. Epidemiologists collect data about a particular disease and track its spread to identify the original mode of transmission. They sometimes work in close collaboration with historians to try to understand the way a disease evolved geographically and over time, tracking the natural history of pathogens. They gather information from clinical records, patient interviews, surveillance, and any other available means. That information is used to develop strategies, such as vaccinations (Figure 22.26), and design public health policies to reduce the incidence of a disease or to prevent its spread. Epidemiologists also conduct rapid investigations in case of an outbreak to recommend immediate measures to control it. An epidemiologist has a bachelor's degree, plus a master's degree in public health (MPH). Many epidemiologists are also physicians (and have an M. ), or they have a Ph. in an associated field, such as biology or microbiology. Choices: - biologist - entymologist - anthropologist - epidemiologist A:
epidemiologist
