A DNA molecule is like a ladder because there are two sides (the sugar-phosphate backbones of the two strands) and rungs (each rung being a pair of complementary bases). Twisted, because the molecule is twined in a coil called a helix - or rather, a double helix because there are two strands.
The third one,
Autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy. Plants also use glucose to make cellulose, a substance they use to grow and build cell walls.
Answer:
G-T-A-G-C-T
Explanation:
A always pair with T and G always pairs with C.
The increase in insulin level following an increase in glucose level in the blood can best be explained by A FEED BACK MECHANISM THAT REGULATE THE BLOOD GLUCOSE LEVEL.
Insulin is an hormone that is secreted by the pancreas and it functions by regulating the amount of glucose that is found in the blood. When the level of glucose in the blood is higher than normal, insulin interfere by converting the excess glucose into glycogen. The glycogen is stored in the liver and in the skeletal muscles and they will only be converted back into glucose, if the level of glucose in the blood is lower than normal.
I'm pretty sire the answer to this would be
