Ques: Answer the following question given this paragraph: There are three main ways that molecules can pass through a phospholipid membrane. The first way requires no energy input by the cell and is called passive transport. The second way requires that the cell uses energy to pull in or pump out certain molecules and ions and is called active transport. The third way is through vesicle transport, in which large molecules are moved across the membrane in bubble-like sacks that are made from pieces of the membrane. Q: How many different ways can molecules pass through a phospholipid membrane? Choices: - six - five - four - three A:
Ans: three

These individuals have misshapen facial features, and the infant's cry resembles a cat's cry. Q: Which chromosome is associated with cri du chat syndrome? Choices: - collagen 5 - genome 5 - spore 5 - chromosome 5 A:
Ans:
chromosome 5
