Q: The cells of the blastocyst form an inner cell mass called the what? Read this paragraph and choose the correct option from the provided answers: The cells of the blastocyst form an inner cell mass and an outer cell layer, as shown in Figure below . The inner cell mass is called the embryoblast. These cells will soon develop into an embryo. The outer cell layer is called the trophoblast. These cells will develop into other structures needed to support and nourish the embryo. Choices: - blastocyst - chloroplast - xerophyte - embryoblast A:
embryoblast

Q: Why are living things considered to be renewable? Read this paragraph and choose the correct option from the provided answers: Living things are considered to be renewable. This is because they can reproduce to replace themselves. However, they can be over-used or misused to the point of extinction. To be truly renewable, they must be used sustainably. Sustainable use is the use of resources in a way that meets the needs of the present and also preserves the resources for future generations. Choices: - they inherit traits - they evolve - they decompose - they reproduce A:
(Answer)
they reproduce

Ques: Q: What happens to the temperature of matter as light is absorbed? Read this paragraph and choose the correct option from the provided answers: http://www. chem. ufl. edu/~itl/2045/lectures/lec_d. html. Choices: - it stays the same - it triples - it drops - it increases A:
Ans: it increases

Q: Structures like the human tail bone and whale pelvis are called what? Read this paragraph and choose the correct option from the provided answers: Structures like the human tail bone and whale pelvis are called vestigial structures . Evolution has reduced their size because the structures are no longer used. The human appendix is another example of a vestigial structure. It is a tiny remnant of a once-larger organ. In a distant ancestor, it was needed to digest food. It serves no purpose in humans today. Why do you think structures that are no longer used shrink in size? Why might a full-sized, unused structure reduce an organism's fitness?. Choices: - primordial structures - parasitic structures - adaptations - vestigial structures A:
(A).
vestigial structures

Ques:Q: From what do tubeworms found deep in the galapagos rift get their energy from? Read this paragraph and choose the correct option from the provided answers: Tubeworms deep in the Galapagos Rift get their energy from chemosynthetic bacteria. Tubeworms have no mouth, eyes or stomach. Their survival depends on a symbiotic relationship with the billions of bacteria that live inside them. These bacteria convert the chemicals that shoot out of the hydrothermal vents into food for the worm. Choices: - chemosynthetic plants - chemosynthetic fish - chemosynthetic viruses - chemosynthetic bacteria A:

Ans:chemosynthetic bacteria

Question: Q: Rust is an example of the reaction of oxygen with what? Read this paragraph and choose the correct option from the provided answers: Reaction with Elements Oxygen reacts directly at room temperature or at elevated temperatures with all other elements except the noble gases, the halogens, and few second- and third-row transition metals of low reactivity (those with higher reduction potentials than copper). Rust is an example of the reaction of oxygen with iron. The more active metals form peroxides or superoxides. Less active metals and the nonmetals give oxides. Two examples of these reactions are: 2Mg(s) + O 2(g) 2MgO(s) P 4(s) + 5O 2(g) P 4 O 10(s) The oxides of halogens, at least one of the noble gases, and metals with higher reduction potentials than copper do not form by the direct action of the elements with oxygen. Choices: - fuel - carbon - coal - iron A:
Answer:
iron
