The average human has between sixty trillion and ninety trillion cells, but there are also organisms that have only a single cell. So basically it depends on the type of organism, but the minimum amount of cells is one.
Answer:
The functional group
Explanation:
A functional group defines a hydrocarbon. an ester the functional group is an O- alkyl group while that one of an alcohol is -OH group. An aldehyde is a functional group on its own.
Answer : A = reactant, B = activated complex, C = product, D = activation energy.
This is an exothermic reaction.
Explanation :
Activated complex : When the reactant molecules absorb energy, their bonds are loosened and new lose bonds are formed between them. The intermediate thus formed is known as activated complex or transition state. It is unstable state and immediately dissociates to form the stable products.
Activation energy : It is defined as the minimum amount of energy absorbed by the reactant molecules so that their energy becomes equal to the threshold energy.
Endothermic reaction : It is a type of chemical reaction where the energy is absorbed from the surrounding. In the endothermic reaction, the reactant are less than the energy of product.
Exothermic reaction : It is a type of chemical reaction where the energy is released into the surrounding. In the exothermic reaction, the energy of reactant are more than the energy of product.
Hence, in the given energy graph, A = reactant, B = activated complex, C = product, D = activation energy. This is an exothermic reaction.
Answer:
b)
Explanation:
Resonance structure differ by placement of electrons only.

Answer:
A. The volume of the water in the graduated cylinder is equal to the volume of the object.
Explanation:
The round object have a higher density than the water (because the objects sinks at the bottom at the beaker as seen in the picture) and will displace a volume of water equal to its own volume. The water will fall from the beaker in the graduated cylinder where the volume may be read. In this scenario we assume that the object will not react with the water.
