Answer:
A carbon atom can form up to four covalent bonds as one carbon atom has four valence electrons (in outermost shell). It is a fact that the number of valence electrons in a atom determines the number of covalent bonds it will form. Thus, each electron in carbon atom is used to form four covalent bonds with various four atoms.
Explanation:
A bond between a carbon and hydrogen atom is a non-polar covalent bond. The non-polar covalent bond are the bonds between two atoms which share equal number of electron(s) with each other. Example: as in case of methane, where one carbon atom shares its 4 outer valence electrons with four hydrogens by sharing equal number of electron.
In contrast, polar covalant bond are the bonds between two atoms which share unequal number of electron(s) with each other. Thus these bonds are partially ionic.

When you breath in you breath in oxygen, which comes from plants, when you breath out, you breath out carbon dioxide, which is what plants breath.
Answer:
Regulating
Explanation:
According to Millennium Ecosystem Assessment, there are four major categories of ecosystem services. These services include:
1. Provisioning
2. Regulating
3. Supporting
4. Cultural
The Regulating category is the category that consists of Air and water quality - Purification, climate, erosion, disease transmission, and pest proliferation - Biological control, and pollination.
The ecosystem services are services or functions rendered by the natural environment that ensure the environment is sustainable and healthy for human use.
