Answer the following question given this paragraph: In other covalent bonds, electrons are shared equally. These bonds are called nonpolar bonds. Neither atom attracts the shared electrons more strongly. As a result, the atoms remain neutral. Figure below shows an example of nonpolar bonds. Q: What is it called when electrons are shared equally? Choices: - polar bonds - helices bonds - metabolized bonds - nonpolar bonds A:
nonpolar bonds

Answer the following question given this paragraph: CHAPTER SUMMARY 1.1 Themes and Concepts of Biology Biology is the science of life. All living organisms share several key properties such as order, sensitivity or response to stimuli, reproduction, adaptation, growth and development, regulation, homeostasis, and energy processing. Living things are highly organized following a hierarchy that includes atoms, molecules, organelles, cells, tissues, organs, and organ systems. Organisms, in turn, are grouped as populations, communities, ecosystems, and the biosphere. Evolution is the source of the tremendous biological diversity on Earth today. A diagram called a phylogenetic tree can be used to show evolutionary relationships among organisms. Biology is very broad and includes many branches and sub disciplines. Examples include molecular biology, microbiology, neurobiology, zoology, and botany, among others. Q: Living things are highly organized following a hierarchy that includes atoms, molecules, organelles, cells, tissues, organs, and organ systems. organisms, in turn, are grouped as populations, communities, ecosystems, and this? Choices: - hydrosphere - bionicsphere - endosphere - biosphere A:
(Answer)
biosphere
Ques: Answer the following question given this paragraph: For decades Pluto was a planet. But even then, scientists knew it was an unusual planet. The other outer planets are all gas giants. Pluto is small, icy and rocky. With a diameter of about 2400 kilometers, it has only about 1/5 the mass of Earth's Moon. The other planets orbit in a plane. Pluto's orbit is tilted. The shape of the orbit is like a long, narrow ellipse. Pluto's orbit is so elliptical that sometimes it is inside the orbit of Neptune. Q: Pluto's orbit is so elliptical that sometimes it is inside the orbit of which planet? Choices: - titan - Mars - Earth - neptune A:
Ans: neptune

Not only that food scraps can also be converted into green energy. Q: Cow manure can have a second life as a source of what gas? Choices: - freon - hydrogen - ethanol - methane A:
(A).
methane
Ques:Answer the following question given this paragraph: reproductive structure produced by a seed plant that contains an embryo and food supply enclosed within a hull. Q: Where is the food supply and embryo stored in a seed? Choices: - epicotyl - plumule - tegmen - hull A:

Ans:hull
Answer the following question given this paragraph: Cancer is a disease that causes cells to divide out of control. Normally, the body has systems that prevent cells from dividing out of control. But in the case of cancer, these systems fail. Cancer is usually caused by mutations. Mutations are random errors in genes. Mutations that lead to cancer usually happen to genes that control the cell cycle. Because of the mutations, abnormal cells divide uncontrollably. This often leads to the development of a tumor. A tumor is a mass of abnormal tissue. As a tumor grows, it may harm normal tissues around it. Anything that can cause cancer is called a carcinogen . Carcinogens may be pathogens, chemicals, or radiation. Q: Which disease causes cells to divide out of control Choices: - autoimmune diseases - mutation - arthritis - cancer A:
cancer
