The carbon that plants need for photosynthesis comes from (carbon dioxide gas in the atmosphere)
Answer:
The evolution of the organisms can be explained on the different evidences like biochemical evidence, molecular evidence, morphological evidence and fossil evidence.
The fossil evidence indicates the direct evidence of the evolution. The feather present in the dinosaurs is used as the insulation that provide the heat to the birds. Later on the crowding on the land forms leads to the adaptation of the flight in the dinosaurs.
Answer:
In a chemical reaction the total mass of all the substances taking part in the reaction remains the same. Also, the number of atoms in a reaction remains the same. ... The law of conservation of mass states that the total mass of substances taking part in a chemical reaction is conserved during the reaction.
Explanation:
The correct answer is d. "Regeneration" means "forming new cells," and signifies that the disease-causing bacteria cells are multiplying. When there are more of these cells, there is a higher chance for antibiotic resistance (making it take longer for the antibiotics to work). Once there is a smaller concentration of these bacterial cells, the antibiotics become more effective.
The kidneys are the main osmoregulatory organs in mammalian systems; they function to filter blood and maintain the dissolved ion concentrations of body fluids. They are made up internally of three distinct regions—the cortex, medulla, and pelvis.
