Answer:
A true
Explanation:
Living things are made of four types of molecules, known as macromolecules. These macromolecules are proteins, nucleic acids (DNA and RNA), lipids (fats) and carbohydrates. Each type of macromolecule is made of its own building blocks, which are intricately connected to form different shapes.
Molly's pregnancy had to be terminated during the third month due to severe health complications from diabetes. The third month falls in the first-semester stage of prenatal development where the baby is within the 9-13 weeks of development. At this stage, the baby is already about 2.5 inches long (6.3 centimeters) and weighs more than half an ounce (over 14 grams). Most of the baby’s internal systems are fully formed and working also. However, since the presence of diabetes in pregnancy is very risky and the disease worsens rapidly during pregnancy, it is not safe for both the mother and child, thus some resort to termination of pregnancy on the first semester.

Answer:
The correct answer is A. energy was required to produce the concentration gradient.
Explanation:
There are two types of transport through which a molecule moves in and out of the cell and these are active transport and passive transport. In passive transport, the molecule moves without the help of energy because they move down there concentration. So in passive transport, if concentration gradient changes then passive transport will take place.
In active transport, the molecule move against their concentration gradient with the help of energy or ATP. So in passive transport, the concentration of molecule can be high in the cell because its transport occurred against the gradient with the help of energy. So the correct answer is A.
