Q: What are the two types of optical telescopes? Read this paragraph and choose the correct option from the provided answers: Optical telescopes are designed to collect visible light. The two types of optical telescopes are reflecting telescopes and refracting telescopes.

Q: What is the term for the metabolic reaction where living systems build new molecules? Read this paragraph and choose the correct option from the provided answers: Plants and animals exist in a cycle; each requires products of the other. The thousands of coordinated chemical reactions that keep cells alive are referred to collectively as metabolism. In general, metabolic reactions are divided into two classes: the breaking down of molecules to obtain energy is catabolism, and the building of new molecules needed by living systems is anabolism. Choices: - symbolism - connectionism - metabolism - anabolism A:
(Answer)
anabolism

Ques: Q: Bony fish can live in either of what type of aquatic biome? Read this paragraph and choose the correct option from the provided answers: Bony fish may live in salt water or freshwater. They consume a wide range of foods. For example, they may eat algae, smaller fish, detritus, or dead organisms, depending on the species of fish. Choices: - coral reefs or freshwater - oceans or estuaries - estuaries or saltwater - saltwater or freshwater A:
Ans: saltwater or freshwater

Q: Slime molds have several morphological similarities to fungi, including spore-generation, that are thought to be the result of convergent what? Read this paragraph and choose the correct option from the provided answers: Slime Molds A subset of the amoebozoans, the slime molds, has several morphological similarities to fungi that are thought to be the result of convergent evolution. For instance, during times of stress, some slime molds develop into spore-generating fruiting bodies, much like fungi. The slime molds are categorized on the basis of their life cycles into plasmodial or cellular types. Plasmodial slime molds are composed of large, multinucleate cells and move along surfaces like an amorphous blob of slime during their feeding stage (Figure 23.27). Food particles are lifted and engulfed into the slime mold as it glides along. Upon maturation, the plasmodium takes on a net-like appearance with the ability to form fruiting bodies, or sporangia, during times of stress. Haploid spores are produced by meiosis within the sporangia, and spores can be disseminated through the air or water to potentially land in more favorable environments. If this occurs, the spores germinate to form ameboid or flagellate haploid cells that can combine with each other and produce a diploid zygotic slime mold to complete the life cycle. Choices: - generation - phenomenon - emergence - evolution A:
(A).
evolution

Ques:Q: What component of cells is present in plant and bacterial cells but not animal cells? Read this paragraph and choose the correct option from the provided answers: Animal Cell. The shape of an animal cell is not constrained by a rigid cell wall. A bacterial cell is shown above for comparison. Choices: - nucleus - plasma - mitochondria - cell wall A:

Ans:cell wall

Q: In addition to spiral cleavage, protostomes also undergo which other form of cleavage? Read this paragraph and choose the correct option from the provided answers: There is a second distinction between the types of cleavage in protostomes and deuterostomes. In addition to spiral cleavage, protostomes also undergo determinate cleavage. This means that even at this early stage, the developmental fate of each embryonic cell is already determined. A cell does not have the ability to develop into any cell type. In contrast, deuterostomes undergo indeterminate cleavage, in which cells are not yet pre-determined at this early stage to develop into specific cell types. These cells are referred to as undifferentiated cells. This characteristic of deuterostomes is reflected in the existence of familiar embryonic stem cells, which have the ability to develop into any cell type until their fate is programmed at a later developmental stage. Choices: - straight - diagonal - dispersive - determinate A:
determinate
