[Q]: Please answer correctly the following question related to the paragraph below. Which brother did not have trisomy X? Two brothers born three years apart were very different. Jim had no genetic abnormalities, while Danny had Klinefelter's syndrome. Hint: Klinefelter's syndrome is caused by the presence of one or more extra copies of the X chromosome in a male's cells. Extra genetic material from the X chromosome interferes with male sexual development, preventing the testicles from functioning normally and reducing the levels of testosterone. Triple X syndrome (trisomy X) results from an extra copy of the X chromosome in each of a female's cells. Females with trisomy X have a lower IQ than their siblings. Turner syndrome results when each of a female's cells has one normal X chromosome and the other sex chromosome is missing or altered. The missing genetic material affects development and causes the characteristic features of the condition, including short stature and infertility.

[Q]: Please answer correctly the following question related to the paragraph below. Which month is colder in the northern hemisphere, August or February? Stan moved from the US to Australia, and he still gets confused because of the seasons in the southern hemisphere and the fact that they use the same calendar as the rest of the world. Hint: During May, June, and July, the Northern Hemisphere is exposed to more direct sunlight because the hemisphere faces the Sun. The same is true of the Southern Hemisphere in November, December, and January. It is Earth's axial tilt that causes the Sun to be higher in the sky during the summer months, which increases the solar flux. However, due to seasonal lag, June, July, and August are the warmest months in the Northern Hemisphere while December, January, and February are the warmest months in the Southern Hemisphere.

[Q]: Please answer correctly the following question related to the paragraph below. Which brother had a greater chance of developing cardiovascular diseases? Two brothers were born 20 years apart. Tom, the older brother, was 72, while Dan was 52 years-old. they got along pretty well. Hint: During late adulthood, the risk of developing diseases such as cardiovascular diseases and cancer continues to rise. Most people also have a decline in strength and stamina. Their senses may start failing, and their reflex time typically increases. Their immune system also doesn't work as well as it used to. As a result, common diseases like the flu may become more serious and even lead to death. The majority of late adults develop arthritis, and as many as one in four develop Alzheimer's disease.

[Q]: Please answer correctly the following question related to the paragraph below. Which group learned less about protozoa that graze on algae? Two groups of students learned about protozoa for a school project. Group P studied more about predatory protozoa, while group G studied about grazing and parasitic protozoa, plus portozoa as food sources. Hint: Protozoa generally feed by engulfing and digesting other organisms. As consumers, they have various roles in food chains and webs. Some are predators. They prey upon other single-celled organisms, such as bacteria. In fact, protozoa predators keep many bacterial populations in check. Other protozoa are herbivores. They graze on algae. Still others are decomposers. They consume dead organic matter. There are also parasitic protozoa that live in or on living hosts. For example, the protozoan that causes malaria lives inside a human host. For their part, protozoa are important food sources for many larger organisms, including insects and worms.
