A codon is a sequence of three nucleotides in DNA or RNA that codes for either a particular amino acid or tells the cellular machinery to start or stop using the code. It isn't located anywhere specific.
The answer is A. The ratio goes down as the size of the cell gets larger.
Answer:
The scientific study of life, called <u>Biology</u><u>, </u>can be organized around several themes. As the biological hierachy builds from molecules on up to ecosystems, each level has <u> emergent properties</u> that result from interactions among component parts. Life's basic unit of <u>structure and function</u> is the cell, which occurs in two basic forms- prokaryotic and eukaryotic . As organisms interact with the environment, <u>nutrients and chemicals</u><u> </u>cycle within an ecosystem, while energy flows one way from sunlight -> chemical energy -> heat. According to the core theme of <u>evolution </u>all of life is related by common descent. Life was diversified as <u>natural selection</u> had led to the gradual accumulation of adaptations that fit populations to the environment.
Explanation:
Emergent properties- Properties that is exhibited by a group of individuals as a result of interaction among them.
Evolution- the process by which populations develop new characteristic and become more efficient than their ancestors.
Natural selection- A phenomena in which only fittest organisms of a population are allowed to survive in a given environment. This play a key role in evolution.
Answer:
A. A cell
Explanation:
Cells are the building blocks of life.
They are the biological units of organisms and are the basic structural and functional units of life.
Cells are the smallest units of life.
The answer is
B. animal cell
