Answer:
3. CABD
Explanation:
The gene mapping refers to providing position to the genes on the chromosomes. The first gene map was constructed by the Alfred Sturtevant on the basis of recombinant produces or recombination frequency which was calculated.
The gene mapping refers to providing position to the genes on the chromosomes.
In the given question to construct gene map:
1. Look for the highest recombination frequency that is 50% between the C and D.
2. Now look for second-highest value and place the gene accordingly.
3.Similarly, place the genes in the decreasing order of recombination frequency and this will result that the sequence of the genes is- CABD.
Thus, Option-3 is correct.

Answer:
The correct answer is A) An image indicating the shape of a DNA molecule. See the explanation below, please
Explanation:
Rosalind Franklin through studies of X-ray diffraction and crystallography, showed the double helix structure of the DNA molecule.
Nerve that supply bone accompany blood vessels through the nutrient foramen. They are responsible for the innervation of the bone as well as its outer covering, the periostem, the inner lining of the medullary cavity, the endosteum, and the medullary cavity. The nerves that innervates these structures are mainly sensory nerves that signal injuries to the skeleton.
Blood vessels enter the bones from the periosteum through the nutrient foramen (a small opening or hole in the bone), where the nutrient artery enters and where one nutrient veins exists in bone. The blood vessels supply nutrients and oxygen required by cells and remove the waste products from the cells of the bones.
Endosteum functions to cover and lines the bone, it is an incomplete layer of cells that covers all internal surfaces of the bone within the medullary cavity. It contains the Osteoprogenitor cells, osteoblasts and osteoclasts which are important cells of the bone.
Periosteum on the other hand is a fibrous, thick membrane covering the external surface of the bone, apart from the articular cartilage on the epiphysis. It is made of two layers: the outer fibrous layer of dense irregular connective tissues that protects the bone from external structures, anchors the blood vessels and nerves to the surface of the bone. It also serves as an attachment site for ligaments and tendons. The inner cellular layer contains various cells which includes the osteoprogenitor, osteoclasts and osteoblasts.
