Answer the following question given this paragraph: Aneuploidy An individual with the appropriate number of chromosomes for their species is called euploid; in humans, euploidy corresponds to 22 pairs of autosomes and one pair of sex chromosomes. An individual with an error in chromosome number is described as aneuploid, a term that includes monosomy (loss of one chromosome) or trisomy (gain of an extraneous chromosome). Monosomic human zygotes missing any one copy of an autosome invariably fail to develop to birth because they lack essential genes. This underscores the importance of "gene dosage" in humans. Most autosomal trisomies also fail to develop to birth; however, duplications of some of the smaller chromosomes (13, 15, 18, 21, or 22) can result in offspring that survive for several weeks to many years. Trisomic individuals suffer from a different type of genetic imbalance: an excess in gene dose. Individuals with an extra chromosome may synthesize an abundance of the gene products encoded by that chromosome. This extra dose (150 percent) of specific genes can lead to a number of functional challenges and often precludes development. The most common trisomy among viable births is that of chromosome 21, which corresponds to Down Syndrome. Individuals with this inherited disorder are characterized by short stature and stunted digits, facial distinctions that include a broad skull and large tongue, and significant developmental delays. The incidence of Down syndrome is correlated with maternal age; older women are more likely to become pregnant with fetuses carrying the trisomy 21 genotype (Figure 13.7). Q: An individual with the appropriate number of what for their species is called euploid; abnormalities in this number include trisomy and monosomy? Choices: - ribosomes - neutrons - genes - chromosomes A:
chromosomes
Answer the following question given this paragraph: Q: What are typically arranged into complex tubular networks with extensive surface areas? Choices: - alveoli - hair follicles - Golgi apparatus - transport epithelia A:
transport epithelia
Q: Answer the following question given this paragraph: Ester molecules are polar but have no hydrogen atom attached directly to an oxygen atom. They are therefore incapable of engaging in intermolecular hydrogen bonding with one another and thus have considerably lower boiling points than their isomeric carboxylic acids counterparts. Because ester molecules can engage in hydrogen bonding with water molecules, however, esters of low molar mass are somewhat soluble in water. Borderline solubility occurs in those molecules that have three to five carbon atoms. http://catalog. flatworldknowledge. com/bookhub/reader/2547 - gob-ch15_s07_t01lists the physical properties of some common esters. Q: Lack of which attachment makes ester molecules incapable of intermolecular hydrogen bonding? Choices: - carbon fluorine atom - carbon sulfur atom - carbon oxygen atom - hydrogen-oxygen atom A:
A: hydrogen-oxygen atom
Question: Answer the following question given this paragraph: human body system of glands that release hormones into the blood. Q: Glands release what substance into the blood? Choices: - enzymes - toxins - acids - hormones A:
Answer: hormones

Answer the following question given this paragraph: No doubt you already have a good idea of what temperature is. You might define it as how hot or cold something feels. In physics, temperature is defined as the average kinetic energy of the particles in an object. When particles move more quickly, temperature is higher and an object feels warmer. When particles move more slowly, temperature is lower and an object feels cooler. Q: In physics, _______ is defined as the average kinetic energy of the particles in an object? Choices: - climate - potential energy - heat - temperature A:
**Answer**
temperature

(A).
