When a red blood cell placed in hypertonic solution it will shrink = develops the notched appearance characteristic of crenation.(crenated)
5. Adenine and thymine base pair
6. Chargaff's base ratios
10. Hydrogen bonds exist between base pairs (A/T and G/C) allowing DNA to maintain the helical structure. Adenines and thymines have two hydrogen bonds, guanines and cytosines have three. When these hydrogen bonds are broken, this allows for "unzipping" of the DNA - which can then be replicated, transcribed/translated to RNA, etc.
The parathyroid glands is group of tiny glands that is located in the neck which controls the calcium levels of the body. This gland produces parathyroid hormone (PTH). This hormone raises the blood calcium level by breaking down the bone causing the release of calcium. It also increases the ability of the body to absorb calcium from the food that we eat and it increases the ability of the kidney to hold on to calcium that would be lost in the urine later on.
The regulation of calcium levels in the body is crucial for the heart, nervous system, kidneys and bones to function normally.
Therefore, the answer is parathyroid glands.
