but not identical. Homologous chromosomes would be those coding for brown hair or blonde hair, for example. Different colors, but same trait. 9) Nope!......
6) Uh... I think you need to rephrase this question, it doesn't make sense.
7) Well, sure, you can reduce the risk by doing those things. But if it's genetic, there's always a possibility you'll get it anyone. So, true.
8) No, this is false. Homologous chromosomes are SIMILAR, but not identical. Homologous chromosomes would be those coding for brown hair or blonde hair, for example. Different colors, but same trait.
9) Nope! The citric acid cycle is the Krebs cycle, which is part of cellular respiration. You're looking for photosynthesis.
10) No, heterotrophs have to attain food- autotrophs produce their own food.
Hope this helps! Good luck!
1. During meiosis, chromosome number is reduced through three rounds of cell division.
False. 2 rounds of division
2. A gamete has one-half the number of chromosomes of a regular body cell.
True
3. A Woman with an X-linked dominant genetic disorder will have children who have a 50% chance to be affected by the trait also, regardless of their gender
False. It does not tell us the genotype of the woman. Should could be homozygous dominant, in which case she could only give a 'defective' allele for the trait in her gameter, and 100% of her offspring, whether male or female, would be affected.
4. Sexual reproduction would be more advantageous than asexual reproduction for organisms living in an environment that is diverse and undergoes frequent changes.
True
5. Meiosis occurs during both sexual reproduction and asexual reproduction.
False
6. Recent research suggests that beneficial mutations accumulate faster when species undergo sexual reproduction rather than sexual reproduction
False. You must have copied it wrong becaue they both say sexual reproduction. But as written, it is false, because mutations cannot accumulate faster in sexual reproduction than in sexual reproduction - the rate would have to be the same.
7. A man whose parents both have heart disease is worried that he too will have heart disease. It is possible for him to reduce his risk of the disease by maintaining a healthy diet and by engaging in frequent exercise.
True
8. Homologous chromosomes are two chromosomes with identical DNA sequences.
False. They are two chromosomes that have the same gene loci (the sequence of the genes can differe - that is, they can have different alleles for some genes).
9. Light energy is trapped and converted into chemical energy during the citric acid cycle.
False. During photosynthesis.
10. Heterotrophs produce their own food.
False. Autotrophs do.
