Answer the following question given this paragraph: Chromosomal disorders also occur when part of a chromosome becomes damaged. For example, if a tiny portion of chromosome 5 is missing, the individual will have cri du chat (cat's cry) syndrome. These individuals have misshapen facial features, and the infant's cry resembles a cat's cry. Q: Which chromosome is associated with cri du chat syndrome? Choices: - collagen 5 - genome 5 - spore 5 - chromosome 5 A:
chromosome 5
Answer the following question given this paragraph: Most substances have three distinct phases: gas, liquid, and solid. Phase changes among the various phases of matter depend on temperature and pressure. The existence of the three phases with respect to pressure and temperature can be described in a phase diagram. Two phases coexist (i. , they are in thermal equilibrium) at a set of pressures and temperatures. These are described as a line on a phase diagram. The three phases coexist at a single pressure and temperature. This is known as the triple point and is described by a single point on a phase diagram. A gas at a temperature below its boiling point is called a vapor. Vapor pressure is the pressure at which a gas coexists with its solid or liquid phase. Partial pressure is the pressure a gas would create if it existed alone. Dalton's law states that the total pressure is the sum of the partial pressures of all of the gases present. Q: Temperature and pressure affect changes in phases or states of what? Choices: - homeostasis - decay - energy - matter A:
matter
Q: Answer the following question given this paragraph: The decay of an unstable isotope to a stable element occurs at a constant rate. This rate is different for each isotope pair. The decay rate is measured in a unit called the half-life. The half-life is the time it takes for half of a given amount of an isotope to decay. For example, the half-life of carbon-14 is 5730 years. Imagine that you start out with 100 grams of carbon-14. In 5730 years, half of it decays. This leaves 50 grams of carbon-14. Over the next 5730 years, half of the remaining amount will decay. Now there are 25 grams of carbon-14. How many grams will there be in another 5730 years? Figure below graphs the rate of decay of carbon-14. Q: The decay rate is measured in a unit called the what? Choices: - decay rate - exponential decay - radioactive decay - half-life A:
A: half-life
Question: Answer the following question given this paragraph: Mutations can result in errors in protein sequence, creating partially or completely non-functional proteins. These can obviously result in harm to the cell and organism. To function correctly and maintain homeostasis , each cell depends on thousands of proteins to all work together to perform the functions of the cell. When a mutation alters a protein that plays a critical role in the cell, the cell, tissue, organ, or organ system may not function properly, resulting in a medical condition. A condition caused by mutations in one or more genes is called a genetic disorder or genetic disease. However, only a small percentage of mutations cause genetic disorders; most have no impact on health. If a mutation does not change the protein sequence or structure, resulting in the same function, it will have no effect on the cell. Often, these mutations are repaired by the DNA repair system of the cell. Each cell has a number of pathways through which enzymes recognize and repair mistakes in DNA ( Figure below ). Because DNA can be damaged or mutated in many ways, the process of DNA repair is an important way in which the cell protects itself to maintain proper function. Q: What do you call a condition caused by mutations in one or more genes? Choices: - intrinsic disorder - mutation disorder - evolutionary disorder - genetic disorder A:
Answer: genetic disorder
*Question*
Answer the following question given this paragraph: Are you on the basketball team? Are you a cheerleader? Do you play an instrument in the band? Your niche would be your role or place in the school. Organisms also each have their own niche in the ecosystem. Is an organism a producer or a consumer? How does the organism interact with other organisms? Is the organism involved in any symbiotic relationships?. Q: An organism's unique role in the ecosystem is called its what? Choices: - focus - adaptation - purpose - niche A:
**Answer**
niche
Q: Answer the following question given this paragraph: Excretion is the process of removing wastes and excess water from the body. It is one of the major ways the body maintains homeostasis. Although the kidneys are the main organs of excretion, several other organs also excrete wastes. They include the large intestine, liver, skin, and lungs. All of these organs of excretion, along with the kidneys, make up the excretory system . This lesson focuses on the role of the kidneys in excretion. The roles of the other excretory organs are summarized below:. Q: Excretion is the process of removing excess water and wastes from the body. what are the main organs of excretion? Choices: - eyes - lungs - brains - kidneys A:
A: kidneys
