Answer:
Deletion of two nucleotides.
Explanation:
Every amino acid coded by 3 nucleotides.
12:3=4 (amino acids)
6:3=2 (2 amino acids)
3:3=1 (1 amino acid)
After all of these mutations sequence amino acids change, but after continues stay the same.
Only deletion of 2 nucleotides will completely altered all amino acids encoded without mutation.

Explanation:
An egg is the organic vessel containing the zygote in which an animal embryo develops until it can survive on its own, at which point the animal hatches. An egg results from fertilization of an ovum. Most arthropods, vertebrates, and mollusks lay eggs, although some do not, such as scorpions and most mammals.
Reptile eggs, bird eggs, and monotreme eggs are laid out of water, and are surrounded by a protective shell, either flexible or inflexible. Eggs laid on land or in nests are usually kept within a favorable temperature range (warm) while the embryo grows. When the embryo is adequately developed it hatches, i.e. breaks out of the egg's shell. Some embryos have a temporary egg tooth with which to crack, pip, or break the eggshell or covering.
<span>Echocardiography with doppler flow can show numerous abnormalities, including ventricular hypertrophy, dilation of heart chambers, and abnormal heart wall motion. Place patient in a supine position on their left side facing the equipment. Instruct the patient about the procedure. Inform the patient about sensations that may occur, like pressure and the mechanical movement from the head of the transducer. There are no contraindications to the procedure.</span>
Answer: C. The red blood cells released water through osmosis. The release of water helped the blood cells keep a similar concentration of solutes as the outside solution.
Explanation:
Osmosis is a process whereby water molecules move from an area where they are in higher concentration than a solute to an area where they are in lower concentration. They do this by moving through a selectively-permeable membrane.
With sugar added to the solution, the water in the red blood cells will have a higher concentration of water in the cells than the solution so water molecules will move from the cell - through the cell membrane - to the solution. They will keep doing so till the concentration of solutes are more or less similar in both the cells and the solution.
