Answer the following question given this paragraph: A period is a horizontal row of the periodic table. There are seven periods in the periodic table, with each one beginning at the far left. A new period begins when a new principal energy level begins filling with electrons. Period 1 has only two elements (hydrogen and helium), while periods 2 and 3 have 8 elements. Periods 4 and 5 have 18 elements. Periods 6 and 7 have 32 elements because the two bottom rows that are separated from the rest of the table belong to those periods. They are pulled out in order to make the table itself fit more easily onto a single page. Q: A period is a horizontal row of the what? Choices: - cycles table - phases table - species table - periodic table A:
(Answer)
periodic table
Ques: Answer the following question given this paragraph: What explains buoyant force? Recall from the earlier lesson "Pressure of Fluids" that a fluid exerts pressure in all directions but the pressure is greater at greater depth. Therefore, the fluid below an object exerts greater force on the object than the fluid above the object. This is illustrated in Figure below . Buoyant force explains why objects may float in water. No doubt you've noticed, however, that some objects do not float in water. If buoyant force applies to all objects in fluids, why do some objects sink instead of float? The answer has to do with their weight. Q: What force explains why objects may float in water? Choices: - warm force - cool force - gravity force - buoyant force A:
Ans: buoyant force

Q: Anemia, leukemia, hemophilia, and sickle-cell disease are examples of conditions that primarily affect what? Choices: - Lungs - brain - heart - blood A:
(A).
blood
Ques:Answer the following question given this paragraph: Steroid hormones are made of lipids, such as phospholipids and cholesterol. They are fat soluble, so they can diffuse across the plasma membrane of target cells and bind with receptors in the cytoplasm of the cell (see Figure below ). The steroid hormone and receptor form a complex that moves into the nucleus and influences the expression of genes, essentially acting as a transcription factor. Examples of steroid hormones include cortisol and sex hormones. Q: What are steroid hormones made of? Choices: - water - amino acid - organisms - lipids A:

Ans:lipids
Answer the following question given this paragraph: One of the few innate behaviors in human beings is the grasp reflex. It occurs only in babies. Q: The grasp reflex in humans is an example of what kind of behavior? Choices: - habit - inclination - trait - innate A:
innate
