Energy can be generated without burning fossil fuels

Explanation:

The main positive effect of nuclear power plants is that energy can be generated without burning off fossil fuels.

Nuclear power is an alternate source of energy.

As much as there are problems with disposal of radioactive wastes, nuclear energy does from power plants does not release carbon dioxide into the atmosphere.
Burning of fossil fuel creates an environmental mess by releasing pollutants into the atmosphere.
This way, global warming can result.
Nuclear energy does not involve the burning of any fossil fuel. Nuclear fuels are used in this process.

The process that makes atmospheric nitrogen available to plants by mutualistic and free-living bacteria is called

artcher [175]

Nitrogen fixation is the process that makes atmospheric nitrogen available to plants by mutualistic and free-living bacteria. The process is undertaken by the rhizobium bacteria that live in root roots of plants such as legumes. The mutualistic relationship is that the plant supplies the bacteria with a habitat in which to live, water, and nutrients, and the bacteria supply nitrogen for making plant proteins.

Answer:

Glucose and oxygen are required for cellular respiration. As the law of conversation states, in a biochemical reaction, mass is conserved. The mass of hydrogen in the glucose is therefore conserved in the water molecules products.

In chemical formulas, there are often subscript numbers (such as the 2 in H2O, or the 6, 12, and 6 in C6H12O6).

Roman55 [17]

Answer : The correct option is, Subscript numbers tell us how many of the element to their upper-left there are in the molecule.

Explanation :

Subscript number : It indicates that the total number of atoms of an element present in a molecule.

While witting a chemical formula, first we have to write the symbol of an element and then write the number in the bottom of the symbol.

For example :

$C_6H_{12}O_6$ is the chemical formula of the glucose molecule. The glucose molecule is made up of six carbon atoms, twelve hydrogen atoms and 6 oxygen atoms.

The number 6 of carbon atom is written after and in the bottom (lower-right) of the symbol of carbon element (C). Similarly, the number 12 is written lower-right of the symbol of hydrogen element (H) and the number 6 is written lower-right of the symbol of oxygen element (O).

Therefore, the subscript numbers tell us how many of the element to their upper-left there are in the molecule.
