Answer:
Xylem cells have no cytoplasm or end walls, meaning they form a tube through which water can pass freely to allow water transport. Lignin strengthens the cell walls, helping to support the plant.
Answer:
Option (D)
Explanation:
The entropy is usually defined as the measure of the total thermal energy of a system per unit temperature. This amount of energy is used in performing valuable work. In simple words, it can be said that entropy is related to the disorder or degree of randomness of a particular system. This entropy concept gives proper information regarding the direction along which natural change occurs and is frequently observed in many present-day events.
Thus, the correct answer is option (D).
here is the answer of this qquestion
Deoxyribonucleoside Triphosphate, which is the more specific form of Deoxyribonucletides.
When DNA is synthesised by DNA polymerase by complimentary base pairing, 2 phosphate groups from Deoxyribonucleoside Triphosphate breaks away, releasing energy from the binding of the Deoxyribonucleotide to the adjacent Deoxyribonucleotide molecule via phosphodiester bond. These molecules will be called Deoxyribonucleoside Monophosphates.
Thus, the general name of the building block of DNA is Deoxyribonucleotide, and the more specific names depend on at which stage of DNA replication you are referring to.
