Most organisms either directly or indirectly use energy from the sun to survive, but not all of them. Plants and some microbes use the energy from the sun to perform photosynthesis.
Blood is the connective tissue that contains large amounts of fluid and transports nutrients wastes and gases.
Blood is considered a connective tissue as it has the same origin as other connective tissues like cartilage and bone cells. Blood also connects the whole body together and transports the needed oxygen, hormones, other nutrients and blood throughout the body and also expels out wastes.
the correct answer you are looking for would be letter B. formation of geological layers
hope this helps :)
Newton's law of gravity defines the attractive force between all objects that possess mass. Understanding the law of gravity offers profound insights into the way our universe functions. Newton, upon observing an apple fall from a tree, began to think along the following lines: The apple is accelerated, since its velocity changes from zero as it is hanging on the tree and moves toward the ground. Thus, by Newton's 2nd Law there must be a force that acts on the apple to cause this acceleration. Let's call this force "gravity", and the associated acceleration the "acceleration due to gravity". Then imagine the apple tree is twice as high. Again, we expect the apple to be accelerated toward the ground, so this suggests that this force that we call gravity reaches to the top of the tallest apple tree. <span>Newton knew that the force which caused the apple's acceleration (gravity) must be dependent upon the mass of the apple. And since the force acting to cause the apple's downward acceleration also causes the earth's upward acceleration (Newton's third law), that force must also depend upon the mass of the earth. </span>
