Answer the following question given this paragraph: The aim of basic science is to discover new knowledge. It leads to a better understanding of the natural world. It doesn't necessarily have any practical use. An example of basic research in life science is studying how yeast cells grow and divide. Yeasts are single-celled organisms that are easy to study. By studying yeast cells, life scientists discovered the series of events called the cell cycle. The cell cycle works not only in yeasts but in all other organisms with similar cells. Therefore, this basic research made a major contribution to our understanding of living things. Watch the following animation to learn more about the basic yeast research and the cell cycle. You can also see yeast cells dividing. Q: What kind of organisms are yeasts? Choices: - bacteria - viruses - protozoa - single-celled A:
single-celled

Answer the following question given this paragraph: The Quaternary Period is the time since the beginning of the ice ages. The climate has been cooler than it was earlier in the Cenozoic. Since the end of the Pleistocene ice ages, which are probably not entirely over, we have been in the Holocene Epoch. The Holocene is also called the Recent. Q: What is the time since the beginning of the ice ages? Choices: - Paleolithic era - Mesozoic epocH - Jurassic period - quaternary period A:
(Answer)
quaternary period
Ques: Answer the following question given this paragraph: The Golgi apparatus is usually made up of five to eight cup-shaped, membrane-covered stacks of discs called cisternae (singular, cisterna ), as shown in Figure below . Both plant and animal cells have a Golgi apparatus. A typical mammalian cell will have 40 to 80 of these stacks. While plant cells can have up to several hundred Golgi stacks scattered throughout the cytoplasm. In plants, the Golgi apparatus contains enzymes that synthesize some of the cell wall polysaccharides. Q: Which organelle is made up of 5 to eight cup shaped, membrane covered stacks of discs known as cisternae? Choices: - vacuole - nucleus - endoplasmic reticulum - golgi apparatus A:
Ans: golgi apparatus
(Q).
Answer the following question given this paragraph: Disposing of industrial waste is one way that human actions pollute the land. This became clear more than 30 years ago in Love Canal, a neighborhood in Niagara Falls, New York. Love Canal may sound lovely, but it is not. Love Canal was and is a disaster. Love Canal been called one of the worst environmental disasters of all time. Q: Love canal was an infamous example of what type of pollution? Choices: - thermal pollution - Land Pollution - Visual Pollution - industrial waste dumping A:
(A).
industrial waste dumping
Ques:Answer the following question given this paragraph: Without communication, animals would not be able to live together in groups. Animals that live in groups with other members of their species are called social animals. Social animals include many species of insects, birds, and mammals. Specific examples are ants, bees, crows, wolves, and human beings. Q: Animals that live in groups with other members of their species are called what? Choices: - available animals - grouping animals - aggressive animals - social animals A:

Ans:social animals
Ques:Answer the following question given this paragraph: When geologic and climatic conditions are changing, evolution may occur more quickly. Thus, long periods of little change may be interrupted by bursts of rapid change. This model of the timing of evolution is called punctuated equilibrium . It is better supported by the fossil record than is gradualism. Q: Fossil records support the idea that periods of little change may be interrupted by bursts of rapid change, an evolutionary model contrasted by what? Choices: - elitism - darwinian - minimalism - gradualism A:

Ans:
gradualism
