Polaris (aka the North Star) has a radius of around 22 million miles, which is about 50 times the size of our sun!
Light from distant galaxies can help us calculate how old the galaxies are. By analyzing how the how the light has changed by the time it reached us, we can find out how old the star system from which it originates is.
chloroplast contains chlorphyll . Chlorophyll is used in photosynthesis to produce glucose . (photosynthesis is a process where green plants manufacture simple sugar (glucose) from carbondioxide and water by using sunlight ) 6co2+6h2o=c6h12o6+6o2
if theres no chloroplast no glucose will be produced so animals will have no energy. chloroplast must be present in order of photosynthesis to take place and produce glucose , when plants produce glucose animals get the energy needed by feeding on plants (in simple words animals eat the sugar that plants have produced )
is to manage the blood circulation to the heart muscle. The Left main
coronary artery (LMCA) distributes blood to the left side of your heart
muscle and the Right coronary artery (RCA) distributes blood to the right
atrium, right ventricle, sinoatrial (SA) and atrioventicular (AV) nodes, which
controls your heart rhythm.
