Q: What kind of biome or climate might you find very close to the earth's poles, as well as up on high mountains? Read this paragraph and choose the correct option from the provided answers: Tundra is found near the poles and up on high mountains. Choices: - tropical - desert - taiga - tundra A:
tundra

Q: What might arthropods use as legs for walking? Read this paragraph and choose the correct option from the provided answers: The jointed appendages of arthropods may be used as legs for walking. Being jointed makes them more flexible. Try walking or climbing stairs without bending your knees, and you'll see why joints are helpful. In most arthropods, the appendages on the head have been modified for other functions. Figure below shows some of head appendages found in arthropods. Sensory organs such as eyes are also found on the head. Choices: - antennae - flagella - cloven hooves - jointed appendages A:
jointed appendages

Q: Q: The process by which leaves collect sunlight and make food is called this? Read this paragraph and choose the correct option from the provided answers: The primary function of leaves is to collect sunlight and make food by photosynthesis. Choices: - budding - glycolysis - pollination - photosynthesis A:
A: photosynthesis

Question: Q: What type of rocks form when sediments are compacted and cemented together? Read this paragraph and choose the correct option from the provided answers: Sedimentary rocks form when sediments are compacted and cemented together. Sediments are pieces of rock. They may be gravel, sand, silt, or clay. Some sedimentary rocks form the solid minerals left behind after a liquid evaporates. Choices: - metamorphic rocks - crystalline rocks - igneous rocks - sedimentary rocks A:
Answer: sedimentary rocks

Q: What happens between particles with opposite charges? Read this paragraph and choose the correct option from the provided answers: When charged particles are close enough to exert force on each other, their electric fields interact. Particles with opposite charges attract each other. Particles with like charges repel each other. Choices: - they become static - they oppose - they repel - they attract A:
**Answer**
they attract

Q: Cells infected with viruses secrete what example of early induced proteins, which travel to adjacent cells and induce them to make antiviral proteins, a sacrifice that protects the surrounding cells? Read this paragraph and choose the correct option from the provided answers: Early induced Proteins Early induced proteins are those that are not constitutively present in the body, but are made as they are needed early during the innate immune response. Interferons are an example of early induced proteins. Cells infected with viruses secrete interferons that travel to adjacent cells and induce them to make antiviral proteins. Thus, even though the initial cell is sacrificed, the surrounding cells are protected. Other early induced proteins specific for bacterial cell wall components are mannose-binding protein and C-reactive protein, made in the liver, which bind specifically to polysaccharide components of the bacterial cell wall. Phagocytes such as macrophages have receptors for these proteins, and they are thus able to recognize them as they are bound to the bacteria. This brings the phagocyte and bacterium into close proximity and enhances the phagocytosis of the bacterium by the process known as opsonization. Opsonization is the tagging of a pathogen for phagocytosis by the binding of an antibody or an antimicrobial protein. Choices: - hormones - prokaryotes - metabolites - interferons A:
interferons
