Answer:
D
Explanation:
An oil boom helps contain the oil so that it is easier for them to skim it off of the water. They aren't meant to clean up oil, only to contain the oil since it does not sink or mix with water.
Answer:
an adaptation can be defined as an inherited trait which confers an evolutionary advantage to the organism in a certain environment
Explanation:
An adaptation, also known as an evolutionary adaptation, can be defined as any physiological and/or morphological inherited trait related to the improved evolutionary fitness of one organism in a particular environment. An adaptation improves the chances of survival and reproduction in a certain environment, thereby organisms carrying the adaptation have more chances to produce descendants and pass their genes to the next generation. Some classical examples of evolutionary adaptations include the long necks of giraffes that help them to eat leaves at the top of trees, light bones of flying birds, etc.
- Thermosphere - Fourth layer of Earth's atmosphere.
- Aurora Borealis - Ionosphere layer of thermosphere.
- Large-scale air turbulence and mixing at this layer - Troposphere
- Stratosphere - Second lowest layer of Earth's atmosphere. No Air turbulence so airplanes fly in this layer.
- The coldest temperatures in the atmosphere occur at the junction- of Stratosphere and mesosphere
- Maximum ozone - Ozone layer in Stratosphere
Explanation:
Atmosphere is formed by mixing of gases. The layers of atmosphere is given below.
1. Troposphere -
- The first layer of the atmosphere.
- Weather occurs in this layer.
2.Stratosphere -
- The second layer of Earth's atmosphere.
- Contains Ozone layer.
3. Mesosphere -
- The third layer above the stratosphere.
- Coldest layer.
4. Thermosphere -
- The fourth layer of the atmosphere.
- Warmest layer.
- Ionosphere - lowest level of thermosphere above mesosphere.
- Aurora Borealis, Northern and Southern lights are seen in this layer.
- Exosphere - outermost layer of thermosphere.
- Satellites are in this layer.
- Outer space with no gravity.
Spores are the reproductive cells that are better adapted to disperse or spread bryophytes and ferns to other places. They can be dispersed by wind.
Due to the fact that the white blood cells can change their shape and squeeze in through smaller parts of the blood flow, they have the ability to protect the immune system from any infections. They able to move easily in the blood flow, meaning that they can stop any infections or illnesses that would have came the person's way. This is why a person that has more white cells is not ill that often because there are more cells able to reach that particular place of infection.
