How can fossil records be useful to determine the relative ages of rock layers and other fossils?

Chemistry
1 answer:
Bingel [31]3 years ago
6 0

Answer:

If the same index fossil is found in different areas, the strata in each area were likely deposited at the same time. Thus, the principle of faunal succession makes it possible to determine the relative age of unknown fossils and correlate fossil sites across large discontinuous areas.

A negative ion is (larger/smaller) than its parent atom.<br> Why?
Kay [80]

Answer:

When an atom attracts extra electrons it becomes a negative ion. The negative ion is larger than the original atom. The positive nucleus remains the same, with the same attractive force. However, this attractive force is now pulling on more electrons and therefore has less effect.

Or

Positive ions are formed by removing one or more electrons from the outermost region of the atom. The opposite is true of negative ions. When electrons are added to form an anion, the increased electron-electron repulsions cause the electrons to spread out more in space. Thus, anions are larger than their parent atoms.

How many kilograms of oseltamivir would be needed to treat all the people in a city with a population of 400000 people if each p
enyata [817]

Answer:

300 kg

Explanation:

The give parameters obtained from a similar question are;

The mass of oseltamivir per capsule = 75 mg

The mass of oseltamivir required, <em>M</em>, is given as follows;

M = The mass of oseltamivir per capsule × The mass taken per person per day × 5 days × The number of people in the city

M = 0.75 mg/capsule × 2 capsule/(day·person) × 5 days × 400,000 people

M = 300,000,000 mg = 300 kg
