Ques:Q: Ribosomes are produced in the nucleolus, and then transported to the what? Read this paragraph and choose the correct option from the provided answers: Ribosomes are produced in the nucleolus, and then transported to the cytoplasm. Ribosomes are made of ribosomal proteins, called ribonucleoproteins , and ribosomal RNA (rRNA). Each ribosome has two parts, a large and a small subunit, as shown in Figure below . The subunits are attached to each other. During translation, the smaller subunit binds to the mRNA, while the larger subunit binds to the tRNA with attached amino acids. When a ribosome finishes reading an mRNA molecule, the two ribosomal subunits disassociate. Choices: - cerebellum - nucleus - cytoskeleton - cytoplasm A:

Ans:cytoplasm

Ques:Q: What type of generators use electromagnetic induction to change kinetic energy to electrical energy? Read this paragraph and choose the correct option from the provided answers: Two important devices depend on electromagnetic induction: electric generators and electric transformers. Both devices play critical roles in producing and regulating the electric current we depend on in our daily lives. Electric generators use electromagnetic induction to change kinetic energy to electrical energy. They produce electricity in power plants. Electric transformers use electromagnetic induction to change the voltage of electric current. Some transformers increase voltage and other decrease voltage. Choices: - conductors - radiators - thermal generators - electric generators A:

Ans:electric generators

Ques:Q: Organisms tend to be larger in size at higher what levels? Read this paragraph and choose the correct option from the provided answers: With less energy at higher trophic levels, there are usually fewer organisms as well. Organisms tend to be larger in size at higher trophic levels, but their smaller numbers result in less biomass. Biomass is the total mass of organisms at a trophic level. The decrease in biomass from lower to higher levels is also represented by Figure above . Choices: - proteolytic - benthic - Secondary Layer - trophic A:

Ans:trophic

Ans:
osmoregulation
