Answer:
92 molecules
Explanation:
DNA or Deoxyribosenucleic acid is polynucleotide made up of several nucleotides containing the genetic information of an organism. In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA, tightly coiled many times around proteins called histones to support its stucture.
Human cells, like myself, contains 23 pairs of chromosomes (46 chromosomes in total). Each pair coming from each parent. Each chromosome is formed by two strands of DNA held together by hydrogen bonds forming the DNA double-helical structure. These two DNA strands form a base pair, which is a unit of two nucleotide bases bound to each other by hydrogen bonds. According to the complementary base pairing rule, Adenine (A) pairs with Thymine (T) while Guanine pairs with Cytosine (C).
Since there are 46 chromosomes in a diploid human cell and each chromosome consists of 2 DNA strands, then, there are 46 × 2 = 92 strands/molecules of DNA in each human diploid cell.
Coelophysis was one of the first true dinosaurs to appear in the late Triassic, is was an agile, bipedal carnivore.
Coelophysis was a small fast running carnivorous dinosaur. Coelophysis was found in Upper Triassic. Coelophysis means 'hollow form', and this comes from the hollow limb bones. Coelophysis was a light-weight hunter that looked like a bird having long legs. The Fossil evidence shows that this dinosaur ate small crocodile-like reptiles. This predator was about 9 feet long.

Answer:
What if xylem were only located in the roots and stems, would fluids still move? No because xylem have stoma that enables transpiration to happen. If you remove xylem, you've removed that "vacuum" that pulls that water upward
