Answer:
B--Organism
Explanation:
Different levels of biological organization start from the least complex object and end at the most complex. Every object has objects preceding it that it is made up of.
In this question, the organ system is made up of several organs. A community is made up of several populations of different people. Think about this now: what makes up a population and is made up of organ systems? The most logical answer here according to the flow is B--an organism. An organism is made up of organ systems and makes up a population, which in turn allows several populations to make up a community.
Answer: a. Photo-periodism
Explanation:
The relative length of the day is considered as a major factor in the development of plants, particularly in sexual reproduction. The plants were grouped considering that the flowering and fruiting occurs only when the length of the day is within certain limits so that these phases are achieved only in certain times of the year. Therefore, some species respond to long days, while others respond to short days, and still, others are capable of responding to all day lengths. The name and meaning of each group became as follows:
Short Day Plants: They are the species that bloom in smaller photoperiods than a critical maximum.
Long day plants. These are the species that bloom in larger photoperiods than a critical minimum.
Neutral day plants: They are those that bloom in a wide range of the photoperiod.
