Q: When naming this type of ion the ending of the element's name is dropped and replaced with the ide suffix? Read this paragraph and choose the correct option from the provided answers: Naming anions is slightly different than naming cations. The ending of the element's name is dropped and replaced with the ide suffix. For example, F - is the fluoride ion, while O 2- is the oxide ion. As is the case with cations, the charge on the anion is indicated by a superscript following the symbol. Common anions are listed in the Table below :. Choices: - amines - oxides - cations - anions A:
anions

Q: The oxygen atom in a water molecule pull the electrons away from the hydrogen atoms which leads to an unequal distribution of what? Read this paragraph and choose the correct option from the provided answers: This model shows the arrangement of oxygen and hydrogen atoms in a water molecule. A water molecule has a bent or angular (non-linear) shape, with an angle of about 105. The nucleus of the oxygen atom attracts electrons more strongly than do the hydrogen nuclei. As a result, the middle part of the molecule near oxygen has a negative charge, and the other parts of the molecule have a positive charge. In essence, the electrons are "pulled" toward the nucleus of the oxygen atom and away from the hydrogen atom nuclei. Water is a polar molecule, with an unequal distribution of charge throughout the molecule. Choices: - nitrogen - atomic mass - orbits - charge A:
(Answer)
charge

Ques: Q: What incredibly successful species has quickly colonized almost all of earth's terrestrial habitats, but also impacted earth, its climate, and its environment? Read this paragraph and choose the correct option from the provided answers: The human species has been incredibly successful. In a relatively short period of time, it has colonized almost all of Earth's terrestrial habitats. Unfortunately, human beings have also impacted Earth, its climate, and its environment. Human actions threaten Earth's valuable biodiversity. Choices: - chimpanzees - birds - fish - humans A:
Ans: humans

(A).
specialized neurons or epithelial cells

Ques:Q: If the electromagnetic repulsion between protons is greater than the strong nuclear force of attraction between them, what do they become? Read this paragraph and choose the correct option from the provided answers: The strong nuclear force works only over very short distances. As a result, it isn't effective if the nucleus gets too big. As more protons are added to the nucleus, the electromagnetic force of repulsion between them gets stronger, while the strong nuclear force of attraction between them gets weaker. This puts an upper limit on the number of protons an atom can have and remain stable. If atoms have more than 83 protons, the electromagnetic repulsion between them is greater than the strong nuclear force of attraction between them. This makes the nucleus unstable, or radioactive, so it breaks down. The following video discusses the strong nuclear force and its role in the atom. The video also introduces the weak nuclear force, which is described next. Choices: - unstable , or experimental - slow , or radioactive - destroyed - unstable, or radioactive A:

Ans:unstable, or radioactive

Question: Q: What cycle vital to plants includes a process called denitrification? Read this paragraph and choose the correct option from the provided answers: 3.4 NITROGEN: RUNNING IN CYCLES Introduction: In the previous assignment, you studied the carbon cycle. In a previous unit, you described the water cycle. Carbon and water are matter. As you learned in the first unit, matter cycles. Nitrogen is another form of matter that cycles. Like water and carbon, nitrogen is essential to life. Also, like water and carbon, its cycles affect you. Therefore it is important that you learn about the nitrogen cycle, how it affects you, and how you affect it. Assignment: There are three parts to this assignment. You must complete all three parts to receive credit for the assignment. Be sure to turn in all three parts at the same time. I will not correct partial assignments. THANKS! PART ONE: 1. Describe the nitrogen cycle. Describe how nitrogen goes from the atmosphere to a form usable to plants, how it is used and excreted by animals, and how it returns to the atmosphere. In your description be sure to explain the words: * decay * denitrification. Choices: - carbon cycle - sedimentation cycle - photosynthesis - nitrogen cycle A:
Answer:
nitrogen cycle
