Answer:
No, since DNA does code for certain traits, others are introduced or changed by the environment. For example, some adaptations are not coded in DNA, such as dying hair. According to the gene, hair is to be black, for example, but it can be changed to look pink. Another example is when a person is first born. When they are, some bacteria enter the system of the baby --- mostly good. Then the baby's gut will be different, and the bacteria in the gut are not coded by the DNA. So, living things are not only the product of DNA, as there are extraneous factors that affect living things as well.

Answer:
A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray. A ray is named using its endpoint first, and then any other point on the ray

Answer:
HEALTH SECTOR(microorganisms have led to the most devastating diseases of man such as HIV VIRUS, HEPATITIS VIRUS, SALMONELLA TYPHI AND PARATYPHI SPPS)
INDUSTRY(microorganisms have led to masses losses due to contamination of foods like the GROWTH OF MOLDS)
ENVIRONMENT most contamination of the environment are caused by microorganisms.
Explanation:Louis Pasteur meant that with the microscopic nature of microorganisms they have been able to make great impact in the world.
IN THE HEALTH SECTOR Microorganisms have been the major cause of the diseases of human and animals world wide, diseases such as Hepatitis A,B,C Virus,Typhoid caused by Bacteria (Salmonella typhy and paratyphy spp) etc have been a cause of a huge number of death.
INDUSTRY
Microorganisms are major causes of loss in the industries leading to large scale contamination of food products, such as Fungi infestation on foods especially of plants origin. MICROORGANISMS ALSO HAVE BENEFITS IN THE INDUSTRY AS IT IS USED IN THE FERMENTATION OF FOOD PRODUCTS.
IN THE ENVIRONMENT
Microorganisms are the major cause of environmental hazards such as the contamination of water bodies, the air (THE HUMAN FLU VIRUS) etc ALL THESE MICROORGANISMS HAVE CAUSED MASSIVE DEATHS THE WORLD OVER.
Answer:
Methotrexate inhibits the synthesis of DNA, RNA, and protein synthesis of the cells in the experiment.
Explanation:
Methotrexate competitively inhibits the enzyme dihydrofolate reductase (DHFR) which is involved in the synthesis of tetrahydrofolate from the inactive dihydrofolate. The methotrexate blocks the enzyme by binding to its active site thereby preventing further reaction of the dihydrofolate reductase enzyme and dihydrofolate. Tetrahydrofolate is a useful material for the de novo synthesis of thymidine, a nucleoside. And without thymidine, DNA synthesis is hindered. Methotrexate therefore inhibits the synthesis of DNA, RNA, thymidylates and of course protein synthesis.
