Answer:
The correct answer is - option C.
Explanation:
Chemical energy is the energy that every substance or chemical have and its not affected by the presence or absence of the enzyme, while the activation energy is the required energy to initiate for a chemical reaction. If the energy of the chemical reaction is less than the activation energy reaction will not take place.
Presence of a enzyme lowers the amount of the energy for the initiating the reaction which is activation energy and the chemical reaction takes place.
Thus, the correct answer is - option C.
Answer:
it has dna that is not contained within a nucleus
Explanation:
The word prokaryote is of Greek origin and means “anterior nucleus” or “before having nucleus”. This meaning gives the impression that it is a primitive structure, and that is exactly what these organisms are about. When compared to eukaryotes, prokaryotic cells are simpler, which leads to the belief that they are more primitive elements in evolutionary history. Thus, it is believed that the first cell was that of a prokaryote being.
The composition of this cell group has few membranes, in general, the only one present is the one that delimits the cell. The prokaryotic cell is characterized by the absence of very well-known and common membranous organelles, such as mitochondria, chloroplast, Golgi complex and nucleus. Regarding the absence of a nucleus, the DNA of this cell is not separated from the cytoplasm by a nucleus.
The prokaryotic cell has a plasma membrane, cytoplasm, free and non-compartmented genetic material (DNA) and ribosomes.
The correct option is D.
Because liquids flow, they can assume the shape of any container in which they are pour. Liquids are able to flow because the particles in liquid move around one another easily. When a liquid is pour inside a container, the container limit the fluidity of the liquid particles, so the liquid take up the shape of the container.<span />
