Answer:
Air pressure is the weight of air molecules.
Explanation:
Air pressure can be described as the force generated by the weight of air on the surface of the Earth. The size and number of the air molecules determine the air pressure.
When the number of molecules in the air increases, it generates more force on the Earth's surface and we say that it is regarded as a rise in the atmospheric pressure. A mercury barometer is a device which is used to measure the air pressure.
Parasitic infections are a primary cause of iron-deficiency anemia in many regions of the globe.
As the name itself says, iron-deficiency anemia is caused by a lack of iron in a person's blood, meaning that there are not enough red blood cells, leading to tiredness, weakness, shortness of breath, paleness, etc. Parasites increase the risk of anemia.
Answer:
The correct answer would be Late.
Explanation:
Glaciers are the dense layers of solid ice which are accumulated on the tops of the mountains, or on the surface of the mountains, or on the rivers, near the poles, and they are moving slowly under their own mass or weight. Glaciers are most likely to advance during the Late Summers. When the summer passes and the heat accumulates and reaches the inner surfaces of the snow, it starts to advance in the late summers due to the continuous exposure to the sunlight. They start to melt and move forward in the late summers and heavy melting usually lead to floods in the nearby towns and cities.
Answer:
Enzymes have specific sites which are known as the active sites. The shape of the active sites is specific for specific kinds of substrates. This allows every enzyme to be specific for its action. Only the specific substrate will be able to fit into the active site and hence, activate the enzyme. The presence of active sites makes the activity of each enzyme specific and hence, every enzyme is able to catalyze a specific kind of reaction.
Answer:
- Earth's atmosphere has a mix of gases organic molecules could have been made from simple chemical reactions involving these gases. ... - Filled up the glass apparatus with water and gases which they thought made up the atmosphere. - Boiled the mixture and shine UV light on it, which mimicked sunlight.
