Answer:
The correct answer option is True.
Explanation:
The measure of the amount of space which an object or a substance can occupy is said to be its volume.
The basic unit of volume in the metric system is a liter while the SI unit of the volume is the cubic meter.
Therefore, the given statement is true.
Answer:
Using aerosols that contain chlorofluorocarbons (CFCs) decreases the amount of protective ozone (O3).
Explanation:
Let's talk about available options and how can they be true or false:
If we talk about option A, it says that radioactive materials cause the addition of methane in ground. As we know that methane is a gas that is present in the atmosphere since its lighter nature. Therefore, the pollution due to methane seeping into the ground do not makes a reasonable cause for pollution.
If we talk about option B, it says that Burning fossil fuels causes water pollution, as we know that burning of fossil fuels is a serious cause of air pollution because it increases the amount of harmful gases in the air. But in option, it is mentioned that fossil fuels cause water pollution which again is not a reasonable cause.
If we talk about option C, it says that deforestation causes acid rain by decreasing carbon dioxide (CO2) in the atmosphere. However in actual deforestation in the cause of enhanced amount of CO2 emissions which in turn cause the acid rainfall. Therefore, the option is clearly wrong.
If we talk about option D, it says that aerosols that contain chlorofluorocarbons (CFCs) decreases the amount of protective ozone (O3). As we know that aerosol sprays are the leading cause of damaging ozone layer and causing big holes in it therefore there is a lot of focus now adays by environmentalists to minimize their usage.
Hence D is correct option.
Hope it help!
<span>Cell theory states that:
1. Cells came from pre-existing cells
2. Cells are the basic unit of life
3. All life is composed of cell/s
More:
The cellular organization relates with one another since the colossal cell, the organ system is fundamentally composed of cells. Cells are the building blocks of these structures and which creates such organ and organ system. They associate as one cell intercommunicates with another cell until all received the message and translates it and sends it with another organ and to cell -vice-versa. And also, they become interdependent with the other cell -other tissue -other organs -other organ system. </span>
Cells when grouped form tissues, when group of tissues are formed together they make organs, some organisms skip from organs to organs systems to form an existing organism as a whole. Describing how is the cells group is the process of multiplication of cell or the so-called cell division, mitosis.This mechanism of each cell produces another cell that binds together and produces again, repeatedly, to be a larger system called now the tissue as explained earlier. <span>How? Through cell division called, mitosis. Excerptmeiosis –cell division specifically in the sex cells.</span>
Mitochondria are responsible for: D. Cellular respiration
Answer:
B,C and D
Explanation:
These are landforms because if you were to travel to the location they were seen on the map they are visible
however Elevation is not a visible mass ( it is a characteristic of a location ) and geosphere is a general term to describe the sections of the earth and atmosphere
Hope this helps!
