Correct Answer: 25
Correct Answer: Rhyolite caldera complexes
Correct Answer: Stratosphere
Explanation:
The ozone layer is a region of Earth's Stratosphere that absorbs most of the Sun's ultraviolet (UV) radiation. It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.
The Atmosphere is divided into 4 layers according to major changes in temperature. They are :
1. Troposphere,
2. Stratosphere,
3. Mesosphere and
4. Thermosphere.
The farther away from earth, the thinner the atmosphere gets.
Correct Answer: 'Rare earth'(They are all metals)
Correct Answer: Steel
Explanation:
The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items.
Correct Answer: Genes found on chromosomes
Correct Answer: AB
Explanation:
In transfusions of packed red blood cells, individuals with type O Rh D negative blood are often called universal donors. Those with type AB Rh D positive blood are called universal recipients.
The immune system of a person with AB blood will accept blood from all possible donors, whether they have O, A, B, or AB blood. Since both A and B antigens are present in a person with AB blood, the recipient won't reject the blood. The body identifies that blood as "self" rather than "foreign."
Correct Answer: An ozone molecule contains one single bond and one double bond
Explanation:
Ozone molecule has one single bond and one double bond.
