plants can also respond to stimulibut the response is usually slower than that of animals.
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
Answer:
A) Cell #1 has a cell wall, and Cell #2 is eukaryotic
Answer: D. Our atmosphere is constantly being heated by the sun.
Radiation is the transmission of energy in the form of waves or particles released by one source and absorbed by another source. Types of radiations includes electromagnetic radiation, particle radiation, acoustic radiations and gravitational radiations.
Our atmosphere is constantly being heated by the sun is the example of the radiation because the sun radiates energy in all directions in the form of heat, light and radiations. Solar energy in the form of radiation is either reflected back to the sun or it is absorbed by the earth atmosphere. Therefore, this causes heating up of the earth atmosphere.
Answer:
In a chemical reaction, only the atoms present in the reactants can end up in the products.
Explanation: No new atoms are created, and no atoms are destroyed. In a chemical reaction, reactants contact each other, bonds between atoms in the reactants are broken, and atoms rearrange and form new bonds to make the products.
