Answer the following question given this paragraph: Oxygen has the second highest electronegativity of any element; consequently, it prefers to share or accept electrons from other elements. Only with fluorine does oxygen form compounds in positive oxidation states. Q: Oxygen has the second highest electronegativity of any element; consequently, it prefers to share or accept electrons from other elements. only with fluorine does oxygen form compounds in this? Choices: - liquid oxidation states - chemical oxidation states - negative Oxidation States - positive oxidation states A:
(Answer)
positive oxidation states
Ques: Answer the following question given this paragraph: Weathering and erosion. Water, wind, ice, and even plants and animals all act to wear down rocks. Over time they can break larger rocks into smaller pieces called sediments. Moving water, wind, and glaciers then carry these pieces from one place to another. The sediments are eventually dropped, or deposited , somewhere. The sediments may then be compacted and cemented together. This forms a sedimentary rock. This whole process can take hundreds or thousands of years. Q: What is the term for the small particles that rocks are worn down to by water and wind? Choices: - fragments - pebbles - organisms - sediments A:
Ans: sediments
(Q).
Answer the following question given this paragraph: Germline mutations occur in gametes. Somatic mutations occur in other body cells. Chromosomal alterations are mutations that change chromosome structure. Point mutations change a single nucleotide. Frameshift mutations are additions or deletions of nucleotides that cause a shift in the reading frame. Q: Where do germline mutations occur in? Choices: - in aggregations - in spores - In blood cells - in gametes A:
(A).
in gametes
Ques:Answer the following question given this paragraph: Most fungi are multicellular, but some exist as single cells. Fungi spend most of their life cycle in the haploid state. They form diploid cells only during sexual reproduction. Like the cells of protists and plants, the cells of fungi have cell walls. But fungi are unique in having cell walls made of chitin instead of cellulose. Chitin is a tough carbohydrate that also makes up the exoskeleton (outer skeleton) of insects and related organisms. Q: What type of state do most fungi spend their lives in? Choices: - triploid - meiosis - diploid - haploid A:

Ans:haploid
Ques: Answer the following question given this paragraph: The peripheral nervous system consists of all the nervous tissue that lies outside the central nervous system. It is connected to the central nervous system by nerves. It has several divisions and subdivisions that transmit nerve impulses between the central nervous system and the rest of the body. Q: Which system consists of all the nervous tissue that lies outside the central nervous system? Choices: - auxiliary nervous system - spinal cord - cerebral cortex - peripheral nervous system A:
Ans:
peripheral nervous system
