For example, they produce a hormone that stimulates bone marrow to produce red blood cells when more are needed. They also secrete a hormone that regulates blood pressure and keeps it in a normal range. Q: What organs secrete hormones that help maintain homeostasis? Choices: - the digestion organs - the lungs - the gonads - the kidneys A:
the kidneys

Answer the following question given this paragraph: The transfer of electrons from the van de Graaff generator to the man is an example of conduction. Conduction occurs when there is direct contact between materials that differ in their ability to give up or accept electrons. A van de Graff generator produces a negative charge on its dome, so it tends to give up electrons. Human hands are positively charged, so they tend to accept electrons. Therefore, electrons flow from the dome to the man's hand when they are in contact. Q: A van de graff generator produces what type of charge on its dome, causing the tendency to give up electrons? Choices: - positive charge - similar charge - no charge - negative charge A:
(Answer)
negative charge

Ques:Answer the following question given this paragraph: You can greatly reduce your risk of developing type 2 diabetes by maintaining a healthy body weight. Some cases of type 2 diabetes can be cured with weight loss. However, most people with the disease need to take medicine to control their blood glucose. Regular exercise and balanced eating also help. Like people with type 1 diabetes, people with type 2 diabetes must frequently check their blood glucose. Q: What must people with type 1 and type 2 diabetes frequently check? Choices: - blood plasma levels - muscle glucose levels - blood density levels - blood glucose levels A:

Ans:blood glucose levels
Answer the following question given this paragraph: Plant Organ Systems In plants, just as in animals, similar cells working together form a tissue. When different types of tissues work together to perform a unique function, they form an organ; organs working together form organ systems. Vascular plants have two distinct organ systems: a shoot system, and a root system. The shoot system consists of two portions: the vegetative (nonreproductive) parts of the plant, such as the leaves and the stems, and the reproductive parts of the plant, which include flowers and fruits. The shoot system generally grows above ground, where it absorbs the light needed for photosynthesis. The root system, which supports the plants and absorbs water and minerals, is usually underground. Figure 30.2 shows the organ systems of a typical plant. Q: When different types of tissues work together to perform a unique function, what do they form? Choices: - organs - Brian - produce - organ A:
organ
