Answer: A. vegetables, meat, chicken
B. insects, fruits, seeds
Explanation:
A primary consumer is the trophic level in the food chain, which feeds upon the plants and other autotrophs. It includes all the herbivorous animals.
A secondary consumer is the trophic level in the food chain, which feeds upon the herbivorous animals. They are carnivores.
A and B are the two correct options. A will feed upon both plant and animal products such as vegetables and meat, and chicken respectively.
Also B also consumes over the plant products such as fruits and seeds and insects.
Answer:
a carboxylic acid and an amine
Explanation:
A functional group is an atom or group of atoms inside a molecule that has comparable chemical properties anytime it appears in numerous compounds. When other parts of the molecule are not similar, some functional groups react in certain manners.
Carboxylic acid is a carbonyl-containing functional group, with carbon atom bonded to an hydroxyl group on one side and on the other side is either a carbon or hydrogen atom.
An amine group is composed of a nitrogen atom bonded to a combination of carbon and hydrogen atoms.
Salt molecule is made up of 2 elements: sodium and chlorine . The sodium and chlorine atoms combine via chemical bonds to form the salt.
So, to seperate one molecule of salt into its constituent atoms i.e. Na and Cl, one must break the chemical bond between them. And these chemical bonds are formed and broken during a chemical reaction only.
Cutting the molecute into two halves is technically not a chemical reaction but is a physical reaction only, thus it is not possible to seperate the salt into Na and Cl atoms by cutting it .
11.....6 for Na, 1 for S and 4 for O
