Ques: Answer the following question given this paragraph: Scientists may work together on a project. One reason is that they can share equipment and personnel. Another reason is that they can share ideas. Scientists may also work separately. Even then, they use each other's data and interpretations. When one scientist publishes a paper, others will replicate the work to make sure they get the same result. If they do, the work is valid. If they don't, someone needs to find the source of the problem. Scientists openly communicate with each other on their results. They also discuss and sometimes disagree on their interpretations. If scientists do disagree, they will look for evidence so that they may resolve the disagreement. Q: What might a scientist do to confirm the work of another? Choices: - question their methods - develop a completely different experiment - study their work - replicate their work A:
Ans: replicate their work

Ques: Answer the following question given this paragraph: Animal and Human Parasites and Pathogens Fungi can affect animals, including humans, in several ways. Fungi attack animals directly by colonizing and destroying tissues. Humans and other animals can be poisoned by eating toxic mushrooms or foods contaminated by fungi. In addition, individuals who display hypersensitivity to molds and spores develop strong and dangerous allergic reactions. Fungal infections are generally very difficult to treat because, unlike bacteria, fungi are eukaryotes. Antibiotics only target prokaryotic cells, whereas compounds that kill fungi also adversely affect the eukaryotic animal host. Many fungal infections ( mycoses) are superficial and termed cutaneous (meaning "skin") mycoses. They are usually visible on the skin of the animal. Fungi that cause the superficial mycoses of the epidermis, hair, and nails rarely spread to the underlying tissue (Figure 13.26). These fungi are often misnamed "dermatophytes" from the Greek dermis skin and phyte plant, but they are not plants. Dermatophytes are also called "ringworms" because of the red ring that they cause on skin (although the ring is caused by fungi, not a worm). These fungi secrete extracellular enzymes that break down keratin (a protein found in hair, skin, and nails), causing a number of conditions such as athlete's foot, jock itch, and other cutaneous fungal infections. These conditions are usually treated with over-the-counter topical creams and powders, and are easily cleared. More persistent, superficial mycoses may require prescription oral medications. Q: Antibiotics only target prokaryotic cells - they do not affect fungi, which are not prokaryotic, but instead what? Choices: - chloroplasts - mammals - plants - eukaryotic A:
Ans: eukaryotic

Ques: Answer the following question given this paragraph: Q: Occuring throughout the lifespan of the organism, what stages proceed in a certain order? Choices: - yearly stages - life effectiveness stages - genetic stages - life cycle stages A:
Ans: life cycle stages

Ques: Answer the following question given this paragraph: Evolution is a change in the characteristics of living things over time. Evolution occurs by a process called natural selection. In natural selection , some living things produce more offspring than others, so they pass more genes to the next generation than others do. Over many generations, this can lead to major changes in the characteristics of living things. Evolution explains how living things are changing today and how modern living things have descended from ancient life forms that no longer exist on Earth. Q: What is the change of characteristics of living things over time? Choices: - spontaneous mutation - adaptation - generation - evolution A:
Ans:
evolution
