Answer:
This question lacks options, the options are:
A) symbiosis
B) ecosystem
C) community
D) population
E) biosphere
The answer is D) Population
Explanation:
Living organisms in an ecosystem are usually found in numbers living together in a given area. This is termed POPULATION in ecology. A population refers to the group of living organisms that belongs to the same species living together in the same habitat and have the ability to interbreed i.e. mate and reproduce with one another.
This is the case in this question where many sandhill cranes (large flying birds) were observed in a particular area, which represented their habitat. Asides the group of sandhill cranes living together, they were also observed to be interbreeding. This was evident in the observation of two sandhill cranes hopping up and down around their bright orange baby. This shows that members of the population are capable of mating and reproducing fertile offsprings.
This observation completes what a POPULATION is all about, hence, a population was observed.
All but 3 because it only contains 1 carbon atom
Answer:
Virus are small infectious particles which act as intracellular parasites. They are considered non-living when they are present outside their host because they show no metabolism outside.
They do not have even cellular level of organization and are basically just packages of nucleic acid and protein. Still, virus have some important features which are common with cell-based life like the presence of nucleic acid as their genetic material.
Apart from the presence of genetic material they also have the ability to evolve like the cell-based life. This evolution allows them to be selected naturally and produce more offspring.
