Q: Many of the protist species classified into the supergroup excavata are asymmetrical, single-celled organisms with a feeding groove "excavated" from one side. this supergroup includes heterotrophic predators, photosynthetic species, and these? Read this paragraph and choose the correct option from the provided answers: Excavata Many of the protist species classified into the supergroup Excavata are asymmetrical, single-celled organisms with a feeding groove "excavated" from one side. This supergroup includes heterotrophic predators, photosynthetic species, and parasites. Its subgroups are the diplomonads, parabasalids, and euglenozoans. Diplomonads Among the Excavata are the diplomonads, which include the intestinal parasite, Giardia lamblia (Figure 23.10). Until recently, these protists were believed to lack mitochondria. Mitochondrial remnant organelles, called mitosomes, have since been identified in diplomonads, but these mitosomes are essentially nonfunctional. Diplomonads exist in anaerobic environments and use alternative pathways, such as glycolysis, to generate energy. Each diplomonad cell has two identical nuclei and uses several flagella for locomotion. Choices: - insects - reptiles - mammals - parasites A:
**Answer**
parasites

Q: What is the condition in which distant objects are seen clearly, but nearby objects appear blurry? Read this paragraph and choose the correct option from the provided answers: Farsightedness, or hyperopia, is the condition in which distant objects are seen clearly, but nearby objects appear blurry. It occurs when the eyeball is shorter than normal (see Figure below ). This causes images to be focused in a spot that would fall behind the retina (if light could pass through the retina). Hyperopia can be corrected with convex lenses. The lenses focus images farther forward in the eye, so they fall on the retina instead of behind it. Choices: - synthesise , or hyperopia - nearsightedness or hyperopia - gleam , or hyperopia - farsightedness, or hyperopia A:
**Answer**
farsightedness, or hyperopia

Q: What type of energy is the energy of moving matter? Read this paragraph and choose the correct option from the provided answers: Kinetic energy is the energy of moving matter. Anything that is moving has kinetic energyfrom atoms in matter to stars in outer space. Things with kinetic energy can do work. For example, the spinning saw blade in the photo above is doing the work of cutting through a piece of metal. Choices: - dynamic energy - residual energy - potential energy - kinetic energy A:
**Answer**
kinetic energy

*Question*
Q: When you heat a pot of water on a stove top, energy moves from the pot to its metal handle by what process? Read this paragraph and choose the correct option from the provided answers: Sunlight is turned into electricity at a solar power plant. These power plants use a large group of mirrors to focus sunlight on one place. This place is called a receiver ( Figure below ). At the receiver, a liquid such as oil or water is heated to a high temperature. The liquid transfers its heat by conduction . In conduction, energy moves between two objects that are in contact. The higher temperature object transfers heat to the lower temperature object. For example, when you heat a pot of water on a stove top, energy moves from the pot to its metal handle by conduction. At a solar power plant, the energy conducted by the heated liquid is used to make electricity. Choices: - induction - convection - thermal radiation - conduction A:
**Answer**
conduction
