Answer the following question given this paragraph: Cnidarians in the polyp form usually reproduce asexually. One type of asexual reproduction in polyps leads to the formation of new medusae. Medusae usually reproduce sexually with sperm and eggs. Fertilization forms a zygote. The zygote develops into a larva, and the larva develops into a polyp. There are many variations on this general life cycle. Obviously, species that exist only as polyps or medusae have a life cycle without the other form. Q: What is the stage between a zygote and polyp? Choices: - pupa - egg - worm - larva A:
larva

Answer the following question given this paragraph: numbers have the same value on both sides, the mass number of the daughter isotope must be 12, and its atomic number must be 6. The element having an atomic number of 6 is carbon. Thus the complete nuclear equation is as follows:. Q: What element has an atomic number of 6? Choices: - silicon - oxygen - hydrogen - carbon A:
(Answer)
carbon
Ques: Answer the following question given this paragraph: The unique sequence for every protein is ultimately determined by the gene encoding the protein. A change in nucleotide sequence of the gene's coding region may lead to a different amino acid being added to the growing polypeptide chain, causing a change in protein structure and function. In sickle cell anemia, the hemoglobin chain (a small portion of which is shown in Figure 3.26) has a single amino acid substitution, causing a change in protein structure and function. Specifically, the amino acid glutamic acid is substituted by valine in the chain. What is most remarkable to consider is that a hemoglobin molecule is made up of two alpha chains and two beta chains that each consist of about 150 amino acids. The molecule, therefore, has about 600 amino acids. The structural difference between a normal hemoglobin molecule and a sickle cell moleculewhich dramatically decreases life expectancyis a single amino acid of the 600. What is even more remarkable is that those 600 amino acids are encoded by three nucleotides each, and the mutation is caused by a single base change (point mutation), 1 in 1800 bases. Q: What determines the unique sequence for every protein? Choices: - form encoding - space encoding - variation encoding - gene encoding A:
Ans: gene encoding

Answer the following question given this paragraph: If you've ever seen a kayak move down a fast-moving river, you know that remaining in the same place would be hard. The river current pulls the kayak along. Pushing the oars back against the water can move the kayak forward in the water, but that only accounts for part of the velocity. The kayak's motion is an example of classical addition of velocities. In classical physics, velocities add as vectors. The kayak's velocity is the vector sum of its velocity relative to the water and the water's velocity relative to the riverbank. Q: The kayak's motion in the water is an example of classical addition of what? Choices: - momentum - force - acceleration - velocities A:
(A).
velocities
Ques:Answer the following question given this paragraph: When the number of electrons and the number of protons are equal, the object is neutral. Q: When the number of electrons and the number of protons are equal, the object is what? Choices: - Negative - Positive - static - neutral A:

Ans:neutral
Answer the following question given this paragraph: Sediments are deposited in an environment of deposition. This can be a sand dune, beach, lake, river bend, or a great number of other locations. Scientists can figure out the environment of deposition of a sedimentary rock by looking at the size of sediments and the sedimentary features in the rock. Q: The term "environment of deposition" is useful for understanding the characteristics of what type of rock? Choices: - glacial - meteor - limestone - sedimentary A:
sedimentary
