Q: What is one way of classifying organisms called? Read this paragraph and choose the correct option from the provided answers: One way of classifying organisms that shows phylogeny is by using the clade. A clade is a group of organisms that includes an ancestor and all of its descendants. Clades are based on cladistics. This is a method of comparing traits in related species to determine ancestor-descendant relationships. Clades are represented by cladograms, like the one in Figure below . This cladogram represents the mammal and reptile clades. The reptile clade includes birds. It shows that birds evolved from reptiles. Linnaeus classified mammals, reptiles, and birds in separate classes. This masks their evolutionary relationships. Choices: - cluster - tuck - spasm - clade A:
clade

Q: The decay rate is measured in a unit called the what? Read this paragraph and choose the correct option from the provided answers: The decay of an unstable isotope to a stable element occurs at a constant rate. This rate is different for each isotope pair. The decay rate is measured in a unit called the half-life. The half-life is the time it takes for half of a given amount of an isotope to decay. For example, the half-life of carbon-14 is 5730 years. Imagine that you start out with 100 grams of carbon-14. In 5730 years, half of it decays. This leaves 50 grams of carbon-14. Over the next 5730 years, half of the remaining amount will decay. Now there are 25 grams of carbon-14. How many grams will there be in another 5730 years? Figure below graphs the rate of decay of carbon-14. Choices: - decay rate - exponential decay - radioactive decay - half-life A:
(A).
half-life

Ques:Q: Deep water filling a void caused by surface winds blowing water north and south is known as? Read this paragraph and choose the correct option from the provided answers: Upwelling also takes place along the Equator. Winds blow the surface water north and south. This leaves a void that deep water can upwell into. The nutrients rise to the surface and support a great deal of life in the equatorial oceans. Choices: - downwelling - surface current - divergence - upwelling A:

Ans:upwelling

Q: Aquatic biomes are determined mainly by distance from shore and what other factor? Read this paragraph and choose the correct option from the provided answers: Aquatic biomes are determined mainly by depth of water and distance from shore. They include freshwater and marine biomes. Choices: - water temperature - salinity - species populations - depth of water A:
depth of water
