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.
The vascular cambium produces secondary phloem and xylem tissue.
Vascular cambium, a plant tissue located between the xylem and the phloem in the stem of a vascular plant. It is also the source of both secondary xylem growth and the secondary phloem growth. Vascular cambium is usually found on dicots and gymnosperms not on monocots which usually lack secondary growth. It does not transport water, dissolved food or minerals by plants.Vascular cambia are cylinders of unspecialized meristem cells which divide to make new cells which specialize to form secondary vascular tissues.<span> </span>

Explanation:
Answer:
a. Tibia
b. Fibula
c. Talus
Explanation:
The ankle joint consists of three bones: the fibula, the tibia and the talus. The first two make up a vault in which the dome of the third fits. It allows, above all, forward and backward turning movements, which are flexion and extension movements of the foot. In the lateral sense, the tops of the peroneal maleolus and tibial maleolus, which are the two bony appendages that continue fibula and tibia on both sides and downward, prevent a complete movement of lateral rotation although they do allow their onset.
The talus rests on the calcaneus (the bone that forms the heel) forming a fairly flat joint, without great movement. This subastragaline joint is a source of conflict as it supports the transmission of body weight forces and governs fine movements of foot stability. When the cartilage of this joint deteriorates, an arthritic degeneration and pain occurs, which sometimes forces surgical intervention to suppress or relieve it.
