Answer the following question given this paragraph: Introduction The individual sexually reproducing organismincluding humansbegins life as a fertilized egg, or zygote. Trillions of cell divisions subsequently occur in a controlled manner to produce a complex, multicellular human. In other words, that original single cell was the ancestor of every other cell in the body. Once a human individual is fully grown, cell reproduction is still necessary to repair or regenerate tissues. For example, new blood and skin cells are constantly being produced. All multicellular organisms use cell division for growth, and in most cases, the maintenance and repair of cells and tissues. Single-celled organisms use cell division as their method of reproduction. Q: The fertilized egg that sexually reproducing organisms begin life as is known as what? Choices: - gamete - fetus - infant - zygote A:
zygote
Answer the following question given this paragraph: In the picture above, a thermal pack is applied to the back. Small packs can be used either for heating or cooling, depending on the material used. A heat pack contains a supersaturated solution of material such as sodium acetate. The solution is clear until a small metal trigger is activated. The sodium acetate then crystallizes out of solution and generates heat in the process. Q: Where can you find sodium acetate? Choices: - table salt - baking soda - a cold pack - a heat pack A:
a heat pack
Q: Answer the following question given this paragraph: Arteries are muscular blood vessels that carry blood away from the heart. They have thick walls that can withstand the pressure of blood being pumped by the heart. Arteries generally carry oxygen-rich blood. The largest artery is the aorta , which receives blood directly from the heart. Q: What is the largest artery in the body called? Choices: - carotid - subclavian - femoral - aorta A:
A: aorta
Question: Answer the following question given this paragraph: Plants are multicellular and eukaryotic, meaning their cells have a nucleus and membrane-bound organelles. Q: Plants are described by what term, meaning their cells have a nucleus and membrane-bound organelles? Choices: - complex - prokaryotic - walled - eukaryotic A:
Answer: eukaryotic

Answer the following question given this paragraph: Red blood cells carry proteins called antigens on their surface. People may vary in the exact antigens their red blood cells carry. The specific proteins are controlled by the genes they inherit from their parents. The particular antigens you inherit determine your blood type. Q: What are the specfic types of proteins that determine your blood type called? Choices: - Plasma - antibodies - Globulins - antigens A:
**Answer**
antigens

Answer the following question given this paragraph: One such strategy is to allow the wind to carry the seeds. With special adaptations in the seeds, the seeds can be carried long distances by the wind. For example, you might have noticed how the "fluff" of a dandelion moves in the wind. Each piece of fluff carries a seed to a new location. If you look under the scales of pine cone, you will see tiny seeds with "wings" that allow these seeds to be carried away by the wind. Maple trees also have specialized fruits with wing-like parts that help seed dispersal ( Figure below ). Q: Why are seeds of a pine cone easily carried by the wind and dispersed? Choices: - seeds are sticky - seeds are small - seeds are dense - seeds have wings A:
**Answer**
seeds have wings
