Answer:
Explanation:
Based on the scenario being described within the question it can be said that the most likely reason for this misconception would be that the spiral galaxies looked like clouds of gas and dust through telescopes because of their distance from Earth. During that time telescopes were still not as advanced and could only see so much, nowadays they are much more advanced and these galaxies are being analyzed and understood more clearly.
the answer is B: so it isa line
Red blood cells will swell and burst.
The reason behind this is that red blood cells are okay when they are in the plasma (the watery part of the blood) because the solutes in plasma are so well balanced that plasma is rendered isotonic. An isotonic solution is a type of solution that has the same salt concentration as its surrounding environment and thus the substances around it e.g. cells neither gain nor lose water. In the blood plasma, the red blood cells neither lose nor gain water and so they remain intact.
However distilled water is hypotonic (has less or no solutes) and therefore osmosis will take place when red blood cell which have a higher solute concentration are placed in it. Water molecules will leave the distilled water and pass into the red blood cells through the semi-permeable membrane of the cells in an attempt to equalize the difference in osmotic pressure on either side of the membrane. In so doing, water will accumulate in the cell which will then swell to capacity and ultimately burst.
he carbon cycle is the circulation and transformation of carbon back and forth between living things and the environment. Carbon is an element, something that cannot be broken down into a simpler substance. Other examples of elements are oxygen, nitrogen, calcium, iron, and hydrogen. Carbon compounds are present in living things like plants and animals and in nonliving things like rocks and soil. Carbon compounds can exist as solids (such as diamonds or coal), liquids (such as crude oil), or gases (such as carbon dioxide). Carbon is often referred to as the "building block of life" because living things are based on carbon and carbon compounds.
The Carbon CycleSource: NASAClick to enlarge
The amount of carbon on the earth and in Earth's atmosphere is fixed, but that fixed amount of carbon is dynamic, always changing into different carbon compounds and moving between living and nonliving things. Carbon is released to the atmosphere from what are called "carbon sources" and stored in plants, animals, rocks, and water in what are called "carbon sinks." This process occurs in a number of steps. In the first step, through photosynthesis (the process by which plants capture the sun's energy and use it to grow), plants take carbon dioxide out of the atmosphere and release oxygen. The carbon dioxide is converted into carbon compounds that make up the body of the plant, which are stored in both the aboveground parts of the plants (shoots and leaves), and the belowground parts (roots). In the next step, animals eat the plants, breath in the oxygen, and exhale carbon dioxide. The carbon dioxide created by animals is then available for plants to use in photosynthesis. Carbon stored in plants that are not eaten by animals eventually decomposes after the plants die, and is either released into the atmosphere or stored in the soil.
