37. The correct answer is d. all of the above. Hyphae are slender filaments that increase the surface area-to-volume ratio of the fungus, allowing for efficient uptake of nutrients.
To arrive at this answer, you can break down the question and evaluate each option:
a. Increase the surface area-to-volume ratio of the fungus: Hyphae are indeed beneficial in increasing the surface area-to-volume ratio of the fungus. This allows for better absorption of nutrients from the environment.
b. Have slender filaments: Hyphae are thin, thread-like structures that make up the body of a fungus. This statement is accurate.
c. Allow for efficient uptake of nutrients: Due to their large surface area, hyphae can efficiently absorb nutrients from their surroundings. This option is correct.
Since all the options are true, the correct answer is d. all of the above.
38. The correct answer is c. translation. In the process of translation, tRNA molecules attach amino acids to the growing chain according to the codons.
To find the answer, break down the question and evaluate each option:
a. Transcription: Transcription is the process of synthesizing mRNA from a DNA template. It does not involve tRNA molecules attaching amino acids to the growing chain.
b. Replication: Replication is the process of copying DNA. It is not related to tRNA molecules attaching amino acids to the growing chain.
c. Translation: Translation is the process in which mRNA is decoded by ribosomes to produce a protein. During this process, tRNA molecules carry specific amino acids to the ribosomes, where they attach to the growing polypeptide chain according to the codons on the mRNA. This option is correct.
d. Transformation: Transformation is a process in molecular biology regarding the transfer of genetic material. It is not related to tRNA molecules attaching amino acids to the growing chain.
Therefore, the correct answer is c. translation.
11. The correct answer is a. the chemical bonds of carbon dioxide. Solar energy can be trapped in the atmosphere by the chemical bonds of carbon dioxide.
To analyze the options:
a. The chemical bonds of carbon dioxide: Carbon dioxide (CO2) is a greenhouse gas that traps solar energy within its chemical bonds. This option is correct.
b. The chemical bonds of ozone: Ozone (O3) is another greenhouse gas, but it does not primarily trap solar energy. Its primary role is to protect the Earth's surface from harmful UV radiation.
c. Radiation: While solar energy does manifest as radiation, this option is not specific enough to capture the mechanism of trapping solar energy.
d. Sunlight: This option is incorrect because sunlight is the source of solar energy, not the mechanism of trapping it.
Therefore, the correct answer is a. the chemical bonds of carbon dioxide.
33. The correct answer is a. their role in the nitrogen cycle. In addition to causing disease, protests (microorganisms) also affect humans through their role in the nitrogen cycle.
To evaluate the options:
a. Their role in the nitrogen cycle: Protests, such as bacteria and fungi, play a crucial role in the nitrogen cycle by converting nitrogen into a usable form for plants and other organisms. This option is correct.
b. Their antibiotic properties: While some microorganisms possess antibiotic properties, this option does not capture the complete impact of protests on humans.
c. Their ability to clean up oil spills: Some microorganisms have the ability to degrade certain pollutants, including oil spills. However, this option does not encompass all the effects.
d. All of the above: This option may seem attractive, but it is incorrect because option b (their antibiotic properties) and option c (their ability to clean up oil spills) are not true for all protests.
Therefore, the correct answer is a. their role in the nitrogen cycle.
I hope this helps! Let me know if you have any further questions.
