Answer the following question given this paragraph: Radioactive decay is the process in which unstable nuclei become stable by emitting particles and energy and changing to different elements. There are three types of radioactive decay: alpha, beta, and gamma decay. Each differs in what is emitted, how far it can travel, and what it can penetrate. Q: What is the process in which unstable nuclei become stable by emitting particles and energy and changing to different elements called? Choices: - nuclear decay - radioactive decrease - initial decay - radioactive decay A:
(Answer)
radioactive decay
Ques: Answer the following question given this paragraph: Water is a compound that consists of the elements hydrogen (H) and oxygen (O). Like other compounds, the smallest particles of water are called molecules. Each molecule of water (H 2 O) contains two atoms of hydrogen and one atom of oxygen. Q: What are the smallest particles of water called? Choices: - hydrogen - atoms - ions - molecules A:
Ans: molecules
(Q).
Answer the following question given this paragraph: The endocrine system consists of glands that secrete hormones into the bloodstream. It is regulated by a part of the brain called the hypothalamus, which also secretes hormones. The hypothalamus controls the pituitary gland, which is called the "master gland" of the endocrine system because its hormones regulate other endocrine glands. Other endocrine glands include the thyroid gland and pancreas. Q: What specific part of the brain regulates the endocrine system? Choices: - parietal lobe - hippocampus - frontal lobe - hypothalamus A:
(A).
hypothalamus
Ques:Answer the following question given this paragraph: Humans have sent spacecraft up to study our star. The SOHO spacecraft has been in operation since 1996. The craft orbits the Sun in step with Earth but closer to it. SOHO has sent back amazing images. Onboard instruments have also sent back mountains of data. The data is mostly about the Sun's outer layers. Q: What year did the soho spacecraft first started to operate? Choices: - 2012 - 2006 - 1987 - 1996 A:

Ans:1996
Question: Answer the following question given this paragraph: ingest their food and usually develop into motile creatures with a fixed body plan. Most members of the animal kingdom have differentiated tissues of four main classesnervous, muscular, connective, and epithelialthat are specialized to perform different functions. Most animals reproduce sexually, leading to a developmental sequence that is relatively similar across the animal kingdom. Organisms in the animal kingdom are classified based on their body morphology and development. True animals are divided into those with radial versus bilateral symmetry. Animals with three germ layers, called triploblasts, are further characterized by the presence or absence of an internal body cavity called a coelom. Animals with a body cavity may be either coelomates or pseudocoelomates, depending on which tissue gives rise to the coelom. Coelomates are further divided into two groups called protostomes and deuterostomes, based on a number of developmental characteristics. Q: Most members of the animal kingdom have differentiated tissues of four main classesnervous, muscular, connective, and this? Choices: - neural - crystalline - digestive - epithelial A:
Answer:
epithelial
