- gamete
- rna
- gene
Q: Answer the following question given this paragraph: Today, we known that characteristics of organisms are controlled by genes on chromosomes (see Figure below ). The position of a gene on a chromosome is called its locus . In sexually reproducing organisms, each individual has two copies of the same gene, as there are two versions of the same chromosome ( homologous chromosomes ). One copy comes from each parent. The gene for a characteristic may have different versions, but the different versions are always at the same locus. The different versions are called alleles . For example, in pea plants, there is a purple-flower allele ( B ) and a white-flower allele ( b ). Different alleles account for much of the variation in the characteristics of organisms. Q: Locus refers to the position of what on a chromosome, which controls the characteristics of an organism? A:
Answer: gene

Problem:OPTIONS:
- pressure
- fuel
- oxygen
- energy

Answer the following question given this paragraph: Describe ways protists are important to humans. Q: All chemical changes involve a transfer of what? A:
****
A: energy

Answer the following question given this paragraph: The galaxies at the edge of the Universe are a great distance away. But they are something else that is distant. Because it takes so long for light from so far away to reach us, they are also very far back in time ( Figure below ). Q: Due to the time it takes for light to reach us, galaxies at the edge of the universe are distant in terms of space and what else? A:
OPTIONS:
- gravity
- temperature
- energy
- time
time

Answer the following question given this paragraph: Alcohols can lose water to form alkenes. Q: What is formed from an alcohol that loses water? A:
OPTIONS:
- Bonds
- alcohols
- amines
- alkenes

Answer: alkenes

Question: Answer the following question given this paragraph: The menstrual cycle includes events that take place in the ovary, such as ovulation. Q: Ovulation takes place in what organ and is part of the menstrual cycle? A:
OPTIONS:
- testes
- fallopian tube
- uterus
- ovary
Answer: ovary

input: OPTIONS:
- laser
- radiation
- extrasound
- ultrasound Now, answer this question: Answer the following question given this paragraph: Any sound with a frequency above 20,000 Hz (or 20 kHz)that is, above the highest audible frequencyis defined to be ultrasound. In practice, it is possible to create ultrasound frequencies up to more than a gigahertz. (Higher frequencies are difficult to create; furthermore, they propagate poorly because they are very strongly absorbed. ) Ultrasound has a tremendous number of applications, which range from burglar alarms to use in cleaning delicate objects to the guidance systems of bats. We begin our discussion of ultrasound with some of its applications in medicine, in which it is used extensively both for diagnosis and for therapy. Characteristics of Ultrasound The characteristics of ultrasound, such as frequency and intensity, are wave properties common to all types of waves. Ultrasound also has a wavelength that limits the fineness of detail it can detect. This characteristic is true of all waves. We can never observe details significantly smaller than the wavelength of our probe; for example, we will never see individual atoms with visible light, because the atoms are so small compared with the wavelength of light. Q: Any sound with a frequency above the highest audible frequency is defined as what, a phenomenon useful in medical diagnosis and therapy? A:
A:
output:
ultrasound
