As a result, it cannot fight off pathogens that a normal immune system would be able to resist. Most commonly, immunodeficiency diseases occur when T or B cells (or both) do not work as well as they should, or when your body doesn't produce enough antibodies. Choices: - anemia - diabetes - stroke - immunodeficiency A:

Ans:immunodeficiency

Ques:Q: What two states of matter are included in the category "fluids"? Read this paragraph and choose the correct option from the provided answers: Fluid friction is friction that acts on objects that are moving through a fluid. A fluid is a substance that can flow and take the shape of its container. Fluids include liquids and gases. If you've ever tried to push your open hand through the water in a tub or pool, then you've experienced fluid friction between your hand and the water. When a skydiver is falling toward Earth with a parachute, fluid friction between the parachute and the air slows the descent (see Figure below ). Fluid pressure with the air is called air resistance. The faster or larger a moving object is, the greater is the fluid friction resisting its motion. The very large surface area of a parachute, for example, has greater air resistance than a skydiver's body. Choices: - solids and gases - bacteria and gases - liquids and soilds - liquids and gases A:

Ans:liquids and gases

Ques:Q: What do you call the splitting of the nucleus of an atom into two smaller nuclei? Read this paragraph and choose the correct option from the provided answers: Nuclear fission is the splitting of the nucleus of an atom into two smaller nuclei. This type of reaction releases a great deal of energy from a very small amount of matter. For example, nuclear fission of a tiny pellet of uranium-235, like the one pictured in Figure below , can release as much energy as burning 1,000 kilograms of coal!. Choices: - critical fission - nuclear fusion - cell division - nuclear fission A:

Ans:nuclear fission
