The diagram shows a cross section of Earth and the layers of Earth's Interior. The diagram also shows the paths of earthquake wa

ves moving
through Earth. These paths were determined by selsmographs detecting the various types of waves reaching points all around the surface of Earth
at different times.

How were earthquake waves able to help geologists determine the different layers of Earth's interior?
O A. Waves traveled at different speeds through different substances Inside Earth.
O B. Geologists determined the depths of layers when the waves were reflected back to the source.
O c. Layers of Earth increased the amplitude of the earthquake waves making them easier to detect.
OD. Earthquake waves made the layers softer allowing geologists to drill shafts down to the inner layers.

How many capillary beds must a red blood cell pass through to move from an artery in the left arm to the left ventricle of the h
MArishka [77]

Answer:

two capillary beds

Explanation:

Capillary beds are networks of capillaries that supply blood to the organs and/or areas of the body, in which nutrients and gas exchange (i.e., O2 and CO2) between red blood cells and tissues take place. Smaller arteries (i.e., arterioles) diverge into capillary beds composed of 10 to 100 capillaries, the smallest blood vessels in the body that connect the arterioles and the venules. Red blood cells usually flow into a capillary bed from a metarteriole (i.e., a microvessel that connects arterioles and capillaries). Red blood cells sometimes pass through two capillary beds before reaching the heart. The left heart ventricle is a muscle required for pumping red O2-rich blood out through the aortic valve into the aorta, whereas arteries are large blood vessels that branch into arterioles in order to carry blood to the capillary beds.

This food web represents a community in a rain forest.
nasty-shy [4]

Answer:

coatis would increase

sloths would increase

fruit bats would increase

Explanation:

The boa constrictor in this food chain is the top predator, thus it is on the top of the food chain. It preys on several of the animals on this list, such as the coati, sloth, and fruit bats, so it is regulating their numbers. If the boa constrictor is removed from the ecosystem, the ecosystem will lose its predator, so the animals on which the boa constrictor preyed upon will have no threat, thus will experience rapid increase in their numbers. The coatis, sloths, and fruit bats, all will be predator free in this scenario, so they will all experience increase in their population, which in turn will have big effect on all other species in the ecosystem.

Explain how random mutations such as those in pathogens with a mutator phenotype may arise in the DNA of an organism
Arada [10]

Answer:

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.
