First, the organism needs to be buried quickly so the bones do not rot, sinking in tar, sand storm sinking in mud etc. Over time more sediment will cover the organism, preventing decay. Being buried quickly and preserved away from predators are one of the reasons why marine life fossils are much more common <span>the terrestrial animals as they are rarely preserved.</span>
Answer;
-Frequency
Explanation
-Wave frequency is the number of waves that pass a fixed point in a given amount of time. The SI unit for wave frequency is the hertz (Hz), where 1 hertz equals 1 wave passing a fixed point in 1 second. A higher-frequency wave has more energy than a lower-frequency wave with the same amplitude.
-The speed of a wave is dependent on four factors: wavelength, frequency, medium, and temperature. Wave speed is calculated by multiplying the wavelength times the frequency. Since speed is constant within the same medium, a high frequency has a short wavelength and vice-a-versa
The name is chemoreceptors; this is because they both respond to chemical in solution. A receptor is a protein molecule that receives chemical signals from outside a cell. When such chemical signals bind to a receptor, they cause some cellular/tissue response; e.g. a change in the electrical activity of a cell. Chemoreceptors are cells specialized to detect chemical substances and relay that information centrally in the nervous system. Chemoreceptors may monitor external stimuli, as in taste and olfaction, or internal stimuli, such as the concentrations of oxygen and carbon dioxide in the blood.
Answer:
four
Explanation:
Carbon atoms have four electrons in their outer shell. So, it exhibits tetravalency & thus, a single carbon atom can form a maximum of four (4) bonds with other atoms
