Q: What type of eukaryotes are protists normally? Read this paragraph and choose the correct option from the provided answers: Most protists are so small that they can be seen only with a microscope. Protists are mostly unicellular (one-celled) eukaryotes. A few protists are multicellular (many-celled) and surprisingly large. For example, kelp is a multicellular protist that can grow to be over 100-meters long ( Figure below ). Multicellular protists, however, do not show cellular specialization or differentiation into tissues. That means their cells all look the same and, for the most part, function the same. On the other hand, your cells often are much different from each other and have special jobs. Choices: - multicellular - photosynthetic - immature - unicellular A:
unicellular

Q: What is the body cavity that reptiles have that is involved in reproduction? Read this paragraph and choose the correct option from the provided answers: Most reptiles have sexual reproduction with internal fertilization. Reptiles have a body cavity called a cloaca that is involved in reproduction. Sperm or eggs are released into an adult reptile's cloaca. Males have one or two penises that pass sperm from their cloaca to the eggs in the cloaca of a female, where fertilization takes place. In most reptile species, once fertilized the eggs leave the body through an opening in the cloaca. These reptiles are oviparous. Eggs develop and hatch outside the mother's body. Choices: - hypothalamus - pristil - ovules - cloaca A:
cloaca

Q: Q: What is the term for the gas in smog that can damage plants? Read this paragraph and choose the correct option from the provided answers: The ozone in smog may damage plants. The effects of ozone add up over time. Plants such as trees, which normally live a long time, are most affected. Entire forests may die out if ozone levels are very high. Other plants, including crop plants, may also be damaged by ozone. You can see evidence of ozone damage in Figure below . Choices: - dioxide - carbon - sulphur - ozone A:
A: ozone

Question: Q: What are butterflies and bees an example of? Read this paragraph and choose the correct option from the provided answers: Choices: - spores - species - parasites - pollinators A:
Answer: pollinators

*Question*
Q: Fertilization occurs if a sperm enters the egg while it is passing through what tube? Read this paragraph and choose the correct option from the provided answers: Fertilization occurs if a sperm enters the egg while it is passing through the fallopian tube. When this happens, the egg finally completes meiosis. This results in two daughter cells that are different in size. The smaller cell is called a polar body . It contains very little cytoplasm. It soon breaks down and disappears. The larger cell is the egg. It contains most of the cytoplasm. This will develop into a child. Choices: - ovarian - anterior - vaginal - fallopian A:
**Answer**
fallopian

Q: The ability for a plasma membrane to only allow certain molecules in or out of the cell is referred to as what? Read this paragraph and choose the correct option from the provided answers: The plasma membrane forms a barrier between the cytoplasm inside the cell and the environment outside the cell. It protects and supports the cell and also controls everything that enters and leaves the cell. It allows only certain substances to pass through, while keeping others in or out. The ability to allow only certain molecules in or out of the cell is referred to as selective permeability or semipermeability. To understand how the plasma membrane controls what crosses into or out of the cell, you need to know its composition. Choices: - periodic permeability - total permeability - moderate permeability - selective permeability A:
selective permeability
