1. What are black holes? Black holes are places where gravity has become so strong that it overwhelms all other forces. Once something enters a black hole‚ nothing can escape its gravity‚ not even light. 2. How do scientists look for black holes in space? Describe what a black hole looks like using one of the different ways of seeing the sky? Scientists look for black holes in space using telescopes that pick up x-ray‚ visible light‚ and radio waves. Using an x-ray telescope‚ a black hole can be

fruit-bearing tree has leathery oblong leaves that are dark green and glossy on the upper surface and golden brown on the underside‚ its fleshy fruits are among the favorites. It has numerous common names including cainito‚ caimito‚ star apple‚ golden leaf tree‚ abiaba‚ pomme du lait‚ estrella‚ milk fruit and aguay. It is also known by the synonym Achras cainito. Leaves of caimito are traditionally applied in the Philippines as a remedy for diarrhea. Decoction of caimito leaves is a superior medicine for

Affective Filter is the fifth hypothesis by Krashen that is composed of ‘affective variables’ which consists of motivation‚ self confidence and anxiety. These variables are said to play a role in second language acquisition. I agree with Krashen that these variables are indeed important in learning for it happened to me in one of my subjects in high school. I don’t really like my teacher and I really hate to attend her class because I don’t like the lesson - paired with her monotonous voice and

Green plants absorb light energy using chlorophyll in their leaves. They use it to react carbon dioxide with water to make a sugar called glucose. The glucose is used in respiration‚ or converted into starch and stored. Oxygen is produced as a by-product. This process is called photosynthesis. Temperature‚ carbon dioxide concentration and light intensity are factors that can limit the rate of photosynthesis. Plants also need mineral ions‚ including nitrate and magnesium‚ for healthy growth. They

An acid is a substance with particular chemical properties including turning litmus paper red‚ neutralizing alkalis‚ and dissolving some metals. It can be corrosive or it can be sour liquid of this kind. Acids are also all around us in everyday life‚ for example‚ carbon dioxide gas dissolves in rain to form carbonic acid (a weak acid). We find acids in many foods‚ such as ethanoic acid in vinegar. These acids are not hazardous. Some acids‚ which are found in the laboratory a car battery are too dangerous

past. In 1979 Ken Fishel was at the intersection of 436 and highway 50 when a woman ran a red light causing him to T-Bone the passenger side of her vehicle. Ken ended up with serious injuries consisting of whip lash and a mild concussion to the head. While the women escaped the accident with minor injuries this could been easily prevented (interview). To combat this problem the United States has placed Red light cameras at certain intersections across the states. Safety should always be the top priority

In light reactions‚ the goal is to transfer solar kinetic energy to chemical potential energy. This is first done by the absorption of a photon of light. Plant pigments are molecules that selectively absorb light energy at wavelengths. A pigment molecule absorbs a photon of light one of pigments electrons jumps to an energy level further than the nucleus. The electron has more potential energy here. The electron now has raised from the ground state to an excited state. Pigments of photosynthesis 1

photosynthesis in Ivy disks Background: All plants are autotrophs meaning they create their own food from inorganic chemicals in their surrounding. In the case of food‚ plants use CO2 to create glucose. In addition to the inorganic chemicals‚ plants use sunlight to create their glucose because the photosynthesis reaction is endothermic. The rate of this reaction‚ in turn‚ can be measures. And this lab uses oxygen which is created as a result of the photosynthesis reaction. Since
