Sometimes when the moon orbits Earth, it moves between the sun and Earth. When this happens, the moon blocks the light of the sun from reaching Earth. This causes an eclipse of the sun, or solar eclipse. During a solar eclipse, the moon casts a shadow onto Earth.
Answer:
C. growth of plants after a forest is destroyed by fire
Explanation:
When the ecological succession occurs on the land or region which was never inhabited by plants previously, the process is called primary succession. On the other hand, secondary succession occurs on land where the existing vegetation was destroyed by some disturbances. Secondary succession is a fast process compared to the primary succession as the soil is already present to support the growth of plants.
Among the given examples, the growth of plants after the vegetation of forest was destroyed by fire represents the process of secondary succession. Growth of vegetation on bare rocks, in the cracks in the concrete surface, or after the melting of glaciers represents the process of primary succession.
This representates the temperature of F degrees Fahrenheit converted to degrees Celsius. Remember that in order to change temperature we need to use the following formula: <span>from Fahrenheit to Celsius: first subtract 32, then multiply by 100/180</span>
Urine differs in composition from the fluid that first enters a nephron tubule by filtration because <u>filtrate has more salts because of reabsorption and secretion</u>.
Filtrate is the liquid that is formed in the kidneys while urine formation is taking place. Water is the major component of urine, forming about 95% of it while the remaining part is formed by other organic and inorganic constituents.
As blood flows through the glomerulus, blood pressure pushes water and solutes from the capillaries into the capsule through a filtration membrane.
