The correct answer is skeletal development resulting in the movement of amphibians onto land and possibly evolved from lobe-finned fishes.
The initial lobe-finned fishes are bony fish with lobed, fleshy, paired fins that are connected with the body by a solitary bone. The fins of the lobe-finned fishes vary from those of all other fish in that each is borne on a lobe like, fleshy, scaly stalk protruding from the body.
This skeletal development will show that the species first developed in water and then gradually move onto the land and ultimately developed as species of land.
Answer: The genetic material must be a DNA double helix.
Explanation:
Genetic material is the material which resides in the nucleus or any other organelles within the cell which is responsible for development of traits in an organism. It is a hereditary material which passes from parents to their offsprings. It is not necessary the genetic material must be stored in the form of double stranded DNA instead it can be stored in the form of RNA which is single stranded genetic material it directly encodes for proteins during translation.
The primary function of the Calvin cycle is to change carbon dioxide into usable energy known as glucose. So Option A.

Answer:
Statement C is the only one that is necessarily true for exons 2 and 3. It is also true for exons 7 and 8. While statements A and B could be true, they don’thave to be. Because the protein sequence is the same in segments of the mRNA that correspond to exons 1 and 10, neither choice of alternative exons (2 versus 3, or 7 versus 8) can alter the reading frame. To maintain the normal reading frame—whatever that is—the alternative exons must have a number of nucleotides that when divided by 3 (the number of nucleotides in a codon) give the same remainder. Since the sequence of the a-tropomyosin gene is known, it is possible to check to see the actual state of affairs. Exons 2 and 3 both contain the same number of nucleotides, 126, which is divisible by 3 with no remainder.
