Answer:
Characteristics of polar molecule
- they should have opposite charge
- they should have same dipole moment value
- they should have electronegativity different
Explanation:
Polar molecule is characterized by an uneven distribution of the electrons that form the covalent bonds between each atoms in the molecule
Polar molecules has a net dipole as a result of opposing charges from polar bonds, since water has slightly positively charged side and a slightly negatively charged side. This makes it a polar molecule
The answer is d. b and c.
Bacteria are simple organisms with great biotic potential and the greatest metabolic diversity on Earth.

Answer:
In normal tissues there is a balance between the generation of new cells via cell division and the loss of cells via cell death. Old cells become damaged over time and are eliminated. This is an essential form of renewal. Examples include shedding of skin cells and the replacement of the cells lining our digestive tract. Like cell division, cell death is also tightly controlled. Cells frequently die by a process termed programmed cell death or apoptosis. 1Apoptosis is the cellular equivalent of a “self destruct” button.
