Examples of direct impacts are things such as littering or planting an invasive plant in an area it doesn't belong.
An indirect impact may be something like how much water your family uses when they use the washer to wash clothes.
I hope these examples help you come up with your 10!
The answer is vacuole and centriole lysosome. An animal cell contains all 3.
An animal cell does not have chloroplasts and a cell wall(a plant has those things). A plant uses chloroplasts (that contains chlorophyll) for photosynthesis. A cell wall is to give the plant a rigid shape(that's why most plant cells look rectangular while animal cells look circular).
Hope this helps :)
<span>The answer to your question is that all of the energy is ultimately radiated into empty outer space as heat. The second law of thermodynamics mandates that all processes that involve the transfer of energy MUST radiate a portion of this energy into space as waste heat. This is why when you run down the street you get hot and sweaty, and this is why automobiles MUST have a functioning radiator and nuclear power stations MUST have evaporation cooling towers or else be located near a large body of water to exchange excess waste heat into, etc., etc. It is also true that the transfer of energy at each step up the food chain is very inefficient. They say it takes around 50 lbs of corn to produce one pound of beef, and it probably takes 20-30 pounds of beef to produce one pound of human tissue. The rest of the energy just goes into your living room as radiated body heat. I hope this helps.</span>
Explanation:
Sickle cell anemia is a disease that is caused by the sickle shape of the oxygen carrier molecule called hemoglobin in the blood. The hemoglobin since is a protein, therefore, is composed of the amino acids and it is the 3 D arrangement of these amino acids which provides proteins its function.
The amino acids are coded by the DNA present in the molecule therefore the shape is the result of the DNA. The mutation in the DNA causes the substitution of the glutamic acid to valine at 6th position.
The glutamic acid contains -COOH group in its R side chain which becomes C00- as a result of which the amino acid is negative and acidic in nature. This negative charge allows the formation of bonds with positive change which stabilizes the structure of the protein.
Valine is a neutral and non-polar amino acid therefore will not form any bond with the proteins and thus a stable structure is not formed. This difference in the side chain in the amino acids is the region the hemoglobin structure is changed.
