Which of the following is the best example of an environmental alliance? Answer: The Kyoto Protocol. Explanation: It was the first comprehensive global environmental treaty signed with the explicit purpose to face global warming and the alarming deterioration of the environment. Which of the following is a part of the general environment? Terms in this […]
Why is diamond hardest?
Why is diamond hardest? The outermost shell of each carbon atom has four electrons. In diamond, these electrons are shared with four other carbon atoms to form very strong chemical bonds resulting in an extremely rigid tetrahedral crystal. It is this simple, tightly-bonded arrangement that makes diamond one of the hardest substances on Earth. What […]
What are the two main stages of cell division called?
What are the two main stages of cell division called? The cell cycle has two major phases: interphase and the mitotic phase (Figure 1). During interphase, the cell grows and DNA is replicated. During the mitotic phase, the replicated DNA and cytoplasmic contents are separated, and the cell divides. Which happens when a cell divides? […]
How do you break the rules of composition?
How long can protists live?
How long can protists live? With simple care, most will last for 5–7 days. Some cultures last longer than others. Euglena and Paramecium cultures, for example, tend to be long-lived, but Volvox is not. Where do most protists live? Most protists are aquatic organisms. They need a moist environment to survive. They are found mainly […]
Why is it called Love wave?
Why is it called Love wave? The first kind of surface wave is called a Love wave, named after A.E.H. Love, a British mathematician who worked out the mathematical model for this kind of wave in 1911. Because it rolls, it moves the ground up and down, and side-to-side in the same direction that the […]
What plants benefit from fire?
What plants benefit from fire? Fire also benefits several plant species such as the endangered sandplain gerardia and wood lily, both which need fire to reproduce and grow. The endangered Delmarva fox squirrel and red-cockaded woodpecker rely on fire to maintain their pine forest habitats. Fire also helps control non-native invasive plant species. How are […]
What is the formula of surface area and volume?
Which materials will float?
Which materials will float? Objects like apples, wood, and sponges are less dense than water. They will float. Many hollow things like empty bottles, balls, and balloons will also float. That’s because air is less dense than water. What is the meaning of sinking object? An object floats when the weight force on the object […]
What happens if the difference in electronegativity is 1.7 How do we determine the type of bond?
What happens if the difference in electronegativity is 1.7 How do we determine the type of bond? If the electronegativity difference is more than 1.7, the bond will have an ionic character. If the electronegativity difference is between 0.4 and 1.7, the bond will have a polar covalent character. How can you tell if a […]
