Answer:
D. archaeal membranes contain L-glycerol.
Explanation:
Archaea and eubacteria differ from each other with respect to the nature of membrane lipids. Lipids present in the membranes of the archaeans have the hydrocarbons derived from isoprene units. These hydrocarbons are branched and are attached to the glycerol with help of ether linkage. Ester linkages are present in eubacteria. The glycerol present in the archaeans is L- glycerol. Bacterial membranes have D-glycerol present in their lipids.
<span>Plants and animals all have a range of limiting (ecological minimum and maximum) for certain environmental factors. The organism will survive provided the temperature, humidity, air etc are maintained within critical limits.</span>
Answer: The correct answer is silent mutation . In this type of mutation there is no change in the phenotype of the individual which means there occurs a mutation where two different amino acid codes for the same protein .There are sequences present in the body where a point mutation occurs but the protein formed is still the same .If you will see the genotype you can easily observe that the amino acid sequence is different but the protein formed is same. Example AAA codes for lysine and the amino acid lysine is formed by AAG .

The correct binomial nomenclature for humans is H. sapiens, in which H. is genus and sapiens is species.
<h3>What is binomial nomenclature?</h3>
The binomial nomenclature is a two-term naming system in which the name of every species is named specifically.
This naming system was developed by Carolus Linnaeus.
It is written as a genus with the following species.
For example the scientific name of the dog is Canis (genus) familiaris (species).
Thus, the scientific name of humans is H. sapiens.
