Answer:
Evolution means change in the physical features of an organism.
Explanation:
Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.
Answer:
Ducks have flat broad beaks with tooth-like edges. They use their beak to take in muddy water which has insects, worms, etc. The mud and the water flow out of the holes on the sides. The worms and insects inside the mouth for the duck to eat.
Stems can be said to be like a street with two way traffic because it performs two sole functions; stem transfers water and minerals to the leaves in upward direction for the photosynthesis to take place by xylem. Also, it transfers the food (glucose) from the leaves to other parts of the plant in downward direction by phloem.
Answer:
Photosynthesis removes carbon from the atmosphere, and cellular respiration releases carbon from the atmosphere
Explanation:
This is the role of the reactions in the carbon cycle.
