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.
Heat from the Sun causes water<span> to evaporate from the surface of lakes and oceans. This turns the liquid </span>water<span> into</span>water<span> vapor in the </span>atmosphere<span>. Plants, too, help </span>water<span> get into the </span>atmosphere<span> through a </span>process<span> called transpiration</span>

Answer:
The laws of learning make learning more interesting to study.
Explanation:
The learning laws were first proposed by Edward Thorndike, a famous psychologist. According to him, there are three rules of learning, they are- readiness of learning, exercise of learning and effect of it.
To make learning lasting and interesting one should always follow these rules. Readiness states- that learning can be adopted only if the learner is ready to, this can be done by arising their interest on the topic by some pre-activity and making them understand that learning is essential; Exercise states: that the more you revise the more you memorise, it involves consistent practice; law of Effect says: learning can be strong and interesting if its associated with satisfying feeling and is weak when associated with unsatisfying feeling.
Psychophiles are bacteria can grow and survive in really low temperatures. These organism are adapted to freezing temperatures by producing antifreeze proteins that protect the organisms from vetrification and dessication. Examples of psychophilic bacteria that can contaminate food include Aeromonas spp and Yersinia spp
