A: can be subject to environmental conditions.
Explanation:
Phenotype is a genetics term used to describe an individual's observable characteristics that result from interactions with the genotype and nonheritable environmental factors.
Phenotypes are the <u>manifested</u> <u>aspects</u> of the morphology, physiology, biochemical properties, behavior and ecological relationships of an organism.
Given these statements, it can be concluded that two organisms cannot have the same phenotype (not even twins), because there will always be, however small, a morphological or physiological difference between them.
many advantage of genetically modified crops. such as diseases free, increase yield according to own desire, we introduce vit A in Golden rice that is useful , etc
Answer:
Louis Pasteur.
Explanation:
Louis Pasteur gave theory of spontaneous generation that states, life arose from non-living things. Pasteur disprove the theory of spontaneous generation by S-shaped tube experiment.
He used swan-neck shaped flasks (twisted necks) and filled the flasks with sterilized beef broth. Due to twisted neck, entry of air was allowed to the flasks from outside, but not microorganisms.
In these sterilized flasks, microorganisms could not grow as entry of airborne microbes was prevented. But if the necks of flasks were broken, growth of microorganisms entered into flasks and showed growth.
Thus, Louis Pasteur showed that microorganisms do not grow spontaneously in flasks with beef broth.
