Answer the following question given this paragraph: These mutations may result in a protein with the same function, with altered function, or with no function. Silent mutations , as they code for the same amino acid, will have no altered effect on the protein. Missense mutations may have a minor effect or a dramatic effect on the protein. Nonsense mutations usually have the most dramatic effet. Depending on the position of the premature stop codon, nonsense mutations may result in an unstable mRNA that cannot be translated, or in a truncated mRNA and a much "smaller" protein without any significant activity. Q: Which kind of mutations have the most dramatic effect on proteins? Choices: - arbitrary mutations - sight mutations - cancerous mutations - nonsense mutations A:
nonsense mutations

Answer the following question given this paragraph: Sperm are released from the body during ejaculation . Ejaculation occurs when muscle contractions propel sperm from the epididymis. The sperm are forced through the ducts and out of the body through the urethra. As sperm travel through the ducts, they mix with fluids from the glands to form semen. Hundreds of millions of sperm are released with each ejaculation. Q: What is released from the body during ejaculation? Choices: - saliva - urine - blood - sperm A:
sperm

Answer the following question given this paragraph: Scientists use the scientific method to answer questions. The scientific method is a series of steps. These steps help scientists (or even just people!) investigate a question. Q: What method do scientists use to answer questions? Choices: - inquisitive method - regulatory method - solutive method - scientific method A:
scientific method

Answer the following question given this paragraph: Most aquatic organisms do not have to deal with extremes of temperature or moisture. Instead, their main limiting factors are the availability of sunlight and the concentration of dissolved oxygen and nutrients in the water. Q: Besides the concentration of dissolve oxygen and nutrients in the water, what other factor limits aquatic organisms? Choices: - rainfall - temperature - lake size - availability of sunlight A:
availability of sunlight
