The answer is they produce endospores.
Explanation:
The endospores are dormant, non-reproductive, tough bacterial spores that ensure the survival of bacteria in adverse conditions.
During the environmental stress, such as starvation, desiccation, radiation and chemical treatment many bacteria form dormant endospores. These endospores germinate again when the conditions become favorable.
Hence, if drought conditions lead the stream to dry up, the bacteria that live there would produce endospores to survive.
Answer:
Nucleic acids
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are made up of nucleic acids found in the nuclei of living cells. They are the vehicles of genetic inheritance.
Nucleic acids are condensation polymers of nucleotides. To understand their functions you will find it helpful to look at how their molecules are built up and the structures of these molecules.

Answer:
Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.
In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
