Q: What is it called when a human has an extra autosome? Read this paragraph and choose the correct option from the provided answers: Trisomy is a state where humans have an extra autosome. That is, they have three of a particular chromosome instead of two. For example, trisomy 18 results from an extra chromosome 18, resulting in 47 total chromosomes. To identify the chromosome number (including an abnormal number), a sample of cells is removed from an individual or developing fetus. Metaphase chromosomes are photographed and a karyotype is produced. A karyotype will display any abnormalities in chromosome number or large chromosomal rearrangements. Trisomy 8, 9, 12, 13, 16, 18, and 21 have been identified in humans. Trisomy 16 is the most common trisomy in humans, occurring in more than 1% of pregnancies. This condition, however, usually results in spontaneous miscarriage in the first trimester. The most common trisomy in viable births is Trisomy 21 . Choices: - monosomy - polysomy - mosaicism - trisomy A:
trisomy

Q: The colorless, odorless gas released when we breath is carbon dioxide. the harmful colorless, odorless gas released when matter is burned is what? Read this paragraph and choose the correct option from the provided answers: Carbon Dioxide: Every time you exhale, you release carbon dioxide into the air. It's an odorless, colorless gas. Carbon dioxide contributes to global climate change, but it isn't directly harmful to human health. Carbon Monoxide: Carbon monoxide is produced when matter burns. It's a colorless, odorless gas that is very harmful to human health. In fact, it can kill people in minutes. Because you can't see or smell carbon monoxide, it must be detected with an alarm. Choices: - carbon trioxide - methane - acid monoxide - carbon monoxide A:
carbon monoxide

Q: Q: During the typical human female ovulation cycles, how many eggs are released? Read this paragraph and choose the correct option from the provided answers: The Zygote Recall that at the point of fertilization, the oocyte has not yet completed meiosis; all secondary oocytes remain arrested in metaphase of meiosis II until fertilization. Only upon fertilization does the oocyte complete meiosis. The unneeded complement of genetic material that results is stored in a second polar body that is eventually ejected. At this moment, the oocyte has become an ovum, the female haploid gamete. The two haploid nuclei derived from the sperm and oocyte and contained within the egg are referred to as pronuclei. They decondense, expand, and replicate their DNA in preparation for mitosis. The pronuclei then migrate toward each other, their nuclear envelopes disintegrate, and the male- and femalederived genetic material intermingles. This step completes the process of fertilization and results in a single-celled diploid zygote with all the genetic instructions it needs to develop into a human. Most of the time, a woman releases a single egg during an ovulation cycle. However, in approximately 1 percent of ovulation cycles, two eggs are released and both are fertilized. Two zygotes form, implant, and develop, resulting in the. Choices: - four - two - three - one A:
A: one

Question: Q: What is the transfer of energy by waves called? Read this paragraph and choose the correct option from the provided answers: Radiation is the transfer of energy by waves. Energy can travel as electromagnetic waves through air or empty space. The Sun's energy travels through space by radiation. After sunlight heats the planet's surface, some heat radiates back into the atmosphere. Choices: - vibration - convection - evaporation - radiation A:
Answer: radiation

Read this paragraph and choose the correct option from the provided answers: What happens when forces of evolution work over a long period of time? The answer is macroevolution. An example is the evolution of a new species. Choices: - substantial evolution - Microevolution - developmental evolution - macroevolution A:
macroevolution
