Ok, so I'm not sure if the man affected with fh has Ff alleles or FF alleles. However, I think by the question that he has Ff alleles. So there is a 50% chance that the offspring will be affected by fh.
Chemotrophs (Bacteria) are essential in the conversion of nitrogen containing compounds to nitrogen forms that are accessible and usable by plants.
Answer:
Explanation:
The O-F glucose test (oxidative-fermentation) is used to determine whether an organism is performs oxidative or fermentative metabolism.
Oxidative metabolism (i.e respiration) takes place in the presence of oxygen while fermentative takes place in the absence of oxygen.
Facultative anaerobes can carry out both fermentation and respiration.
The O-F medium has glucose, peptones and a pH indicator. When the pH of the medium is acidic, that is glucose has been broken down, the medium turns yellow. When it is basic, it turns blue implying that peptone and not glucose had been broken down.
The sealed tube is overlaid with oil so as to prevent oxygen from getting in, making it anaerobic.
The unsealed tube allows oxygen.
Enterics would be yellow is both tubes because they are facultative anaerobes and can grow in the presence or absence of oxygen, hence they carry out both respiration and fermentation.
The question that Charles Darwin would be prompted to ask on his voyage is as follows: can selection in nature also lead to a new species over time?.
<h3>Who is Charles Darwin?</h3>
Charles Darwin was a British naturalist/scientist and founder of the theory of evolution by natural selection.
He is best known for his award-winning work on the origin of species, which he published in 1859. Darwin developed his theory from findings he made following a five-year expedition on board HMS Beagle.
According to this question, Darwin reviewed his observations after he returned home from his voyage studying the selective breeding of pigeons.
