Answer the following question given this paragraph: Sexual reproduction combines gametes from two parents. Gametes are reproductive cells, such as sperm and egg. As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells. When two gametes come together at fertilization, the normal amount of chromosomes results. Gametes are produced by a special type of cell division known as meiosis . Meiosis contains two rounds of cell division without DNA replication in between. This process reduces the number of chromosomes by half. Q: What is the term for reproductive cells, such as sperm and egg? Choices: - spores - nucleus - parasites - gametes A:
gametes

Ques:Answer the following question given this paragraph: Compounds that contain mainly the elements carbon and hydrogen are called organic compounds . This is because they are found mainly in living organisms. Most organic compounds are held together by covalent bonds. An example of an organic compound is glucose (C 6 H 12 O 6 ), which is shown in Figure below . Glucose is a simple sugar that living cells use for energy. All other compounds are called inorganic compounds. Water is an example of an inorganic compound. Q: Compounds that contain mainly the elements carbon and hydrogen are called what kind of compounds? Choices: - microscopic compounds - reactive compounds - natural compounds - organic compounds A:

Ans:organic compounds
