An organ is a group of two or more tissues working together to perform a function. Hence, the organ can be correctly matched with 3.
The tissue is a group of specialized cells working together to perform a specific function. Hence, tissue can be correctly matched with 5.
An organ system is a group of organs working together to perform a function. Hence, organ system can be correctly matched with 2.
An organism refers to a group of organ systems working together to exhibit the six characteristics of life. Hence, the organism can be correctly matched with 1.
A cell is the smallest fundamental unit of life. Hence, the cell can be correctly matched with 4.
Answer:
The correct answer will be option-A.
Explanation:
Photosynthesis is a process which uses sunlight energy to synthesize food in the form of glucose. The process takes place in the chloroplast in two stages: light-dependent reactions and light-independent reactions.
The light-independent reaction produces to convert the carbon dioxide from the atmosphere to glucose through the Calvin cycle. The carbon gets fixed and reduced form+4 state to +1 state.
Respiration is the process which oxidizes the glucose molecule to produce energy in the form of ATP molecules. This ATP is utilized by the cell to perform various functions.
Thus, option-A is the correct answer.
The answer is D. The natural selection is a theory which illustrates the gradual process of evolution in the population due to the change of environment. The key point is the mutation (variation) exists in the population before the environment changing. For C, if the environment does not change, though the adaptation is useful to environment, it will not be selected. Because the organisms without the adaptation will not die.
Charles Darwin noticed that among the same species there were variations in traits based upon geographical location. These changes may have evolved from climate differences, predator/prey relationships and food sources. This particular experiment was intended to duplicate natural selection by demonstrating the concepts with artificial selection. The result was that over time, new traits could be bred for. Although there may be more than one correct answer here, the best answer is the first; desirable traits can be selected and bred in offspring.
It's called a mutualistic relationship! :)
I hope this helps!:)
