The three-domain system is a biological classification introduced by Carl Woese et al.in 1977[1][2] that divides cellular life forms into archaea, bacteria, and eukaryote domains. In particular, it emphasizes the separation of prokaryotes into two groups, originally called Eubacteria (now Bacteria) and Archaebacteria(now Archaea). Woese argued that, on the basis of differences in 16S rRNA genes, these two groups and the eukaryotes each arose separately from an ancestor with poorly developed genetic machinery, often called a progenote. To reflect these primary lines of descent, he treated each as a domain, divided into several different kingdoms. Woese initially used the term "kingdom" to refer to the three primary phylogenic groupings, and this nomenclature was widely used until the term "domain" was adopted in 1990.[2]
Parts of the three-domain theory have been challenged by scientists such as Radhey Gupta, who argues that the primary division within prokaryotes should be between those surrounded by a single membrane, and those with two membranes.

Answer:
D. State-dependent memory
Explanation:
When Fakim's stated drinking again, he got to know where he had hid the bottle because he was in the same state of drinking. As <u>phenomenon of state dependent-memory </u>says that memory retrieval works more efficiently when an individual is in the same state of consciousness as they were when the memory was formed.
Answer: The options are enlisted incorrectly
1. variety
2. balance
3. moderation.
4. calorie control
5. adequacy
The correct answer is adequacy.
Explanation:
Nutrition adequacy can be defined as the sufficient intake of essential nutrients, that are required to fulfill the nutritional requirements for maintaining the optimal health. This involves the sufficient intake of each kind of food so that the body remains free from deficiency.
Other parameters of a diet includes:
Balance: Not too much intake of any kind of food.
Calorie control: Not too much intake of calories.
Moderation: Not too much intake of food containing sugar, salt and fat.
Variety: Intake of as many as different kind of food as possible or including in the diet plan.
