You can prove this by a DNA siblings test, it is the best way to prove a biological relationship
Answer:
The answer is : Carbon catabolite repression
Explanation:
Carbon catabolite repression is a vital part of the global control system of the bacteria and other microorganisms. It allows the microorganisms to quickly adapt to the preferred energy and carbon source first. This is generally achieved by the inhibiting the synthesis of the enzymes that are involved in the catabolism of other carbon sources.
This effect was first shown to be initiated by glucose. Therefore, the carbon catabolite repression is also known as glucose effect.
Answer:
A change in pH will cause many cellular processes to be disrupted because they affect the biomolecules (protein and nucleic acid) responsible for these processes.
Explanation:
pH refers to the degree of acidity or alkalinity. In a cell, the structures and processes that occur in them are impossible without the biomolecules, which are carbohydrate, protein, lipids and protein.
However, unfavorable conditions like a change in pH can cause the structure of some of these biomolecules to be affected. Proteins are made up of amino acids, which gives them their shape that is peculiar to their functioning. Also, nucleic acids such as DNA are composed of nucleotides responsible for their functioning.
A change in pH will cause the bonds of the protein to be disrupted, hence altering its shape and ultimately its functioning. Likewise, the hydrogen bonds in the DNA will be broken in the presence of a high pH causing the DNA to be dysfunctional.
When these biomolecules are affected, the vital functions that they perform in a cell, which is key to the cell's survival are disrupted) are likewise affected. Therefore, the cell is affected negatively.
Industrial melanism is an evolutionary effect prominent in several arthropods, where dark pigmentation has evolved in a habitat affected by industrial pollution, including sulphur dioxide gas and dark soot deposits.
