Answer:
True
Explanation:
Koch's postulates was proposed to show a causative relationship between a microbe and a disease.
Koch's postulates
•The microorganism must be present in large quantity in all organisms affected by the disease, but should not be seen in healthy organisms.
Koch abandoned this due to his discovery of asymptomatic carriers of cholera and of typhoid fever. Asymptomatic or subclinical infection carriers are seen in diseases, especially viral diseases.
•The microorganism must be seperated from a diseased organism and nutured in pure culture.
This can suspended for specific microorganisms or entities which(at the current time) can't be nutured in pure culture. Viruses uses host cells to grow and replicates and not in pure culture.
•The cultured microorganism should lead to disease when it infects a healthy organism.
It says "should", not "must".
NOTE: NOT ALL organisms introduced to an infectious agent will be infected which may be due to certain factors like general health and good immune functioning; vaccination; or genetic immunity. Its best explained using the resistance to malaria as a result of presence of at least one sickle cell allele.
•The microorganism must be reisolated from the inoculated, diseased experimental host and observed as being identical to the basic specific causative agent.
A single pathogen may lead to several disease conditions. A singualr disease infection may be due to several different microorganisms. While some pathogens cannot be cultured in a pure culture in the lab, others can infects humans.
B.DDT was considered harmful and was replaced by other pesticides.
C.DDT was the first modern insecticide.
D.DDT was used in WWII to control malaria and typhus.
The correct answer is B. DDT was considered harmful and was replaced by other pesticides
B. Touch
C. Smell
D. Hearing
B) Let the residents also hire a group to conduct the research and analyze the data.
C) The agricultural chemical industry would be better suited to conduct the research.
D) The research group hired by the farmers may present a biased picture of the situation.
Answer:
The correct answer is option D) "The research group hired by the farmers may present a biased picture of the situation".
Explanation:
One of the basic premises of a reliable scientific investigation is that the researches should not have any conflict of interest. A research group hired by farmers to investigate the claims of local residents regarding the use of insecticides and fungicides most likely would not act unbiased. The proper way to perform the research is to hire an independent research group that would not have any conflict of interest in the matter of study.
Answer:
The correct answer is D)
Explanation:
Here's why:
The research group hired by the farmers may present a biased picture of the situation. An outside agency, one that is not paid by either the residents or the farmers, would be the best group to conduct research and analyze the results in order to find an unbiased solution to the problem. There should be no local involvement in data collection or analysis since any local residents, farmers, or politicians, have their own agenda.
B
The best adapted organisms are most likely to survive
C Organisms become less complex over time
D
Change in organisms occurs suddenly

Answer B
Explanation:
Answer:
convert light energy into chemical energy
Explanation:
According to my research on studies conducted by various biologists, I can say that based on the information provided within the question they convert light energy into chemical energy. Chloroplasts are organelles that conduct photosynthesis, which is the process of convert light energy from the sun to the chemical energy of a glucose molecule
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
The function of the chloroplast is to convert light energy to chemical energy.
The function of the chloroplast is to convert light energy to chemical energy. Chloroplasts are organelles found in plant cells that contain a pigment called chlorophyll. During photosynthesis, chlorophyll absorbs light energy and uses it to convert carbon dioxide and water into glucose and oxygen.
