Cell < Tissue < Organ < Organ system < Organism.

What is the level of organization?

The level of organization may be defined as the process of sequence from the structures that are simplest in nature. It is usually defined by part-whole relationships, with things at higher levels being composed of things at the next lower level.

In organisms, a cell is the fundamental structural and functional unit of life. The collection of cells constitutes the formation of tissue which makes an organ that plays a specific function. Groups of organs form organ systems. While all cells, tissues, organs, and organ systems combine in order to form multicellular organisms.

Therefore, the level of organization in the human body initiates with the cell and processes in the manner which is well-described above.

A researcher found that the wild species of almond trees contains a chemical called amygdalin.
This chemical is converted into cyanide inside the human body and can be lethal. The researcher
found that a single gene mutation in some of the wild almond trees resulted in a variety that no
longer produced the chemical amygdalin. This variety of almond is largely harvested for human
consumption. Based on the study, the researcher claimed that some mutations are beneficial in
nature. Was the claim made by the researcher correct? Why or why not?
a) Yes. The mutated variety of almond was edible.
b) No. Not all almond trees produced seeds that were edible.
c) No. The mutation did not affect all varieties of almond trees.
d) Yes. Almond trees with amygdalin grew only in forests.

Answers

Answer:

a) Yes. The mutated variety of almond was edible.

Explanation:

Yes, the claim made by the researcher is considered correct because the mutation removes the amygdalin chemical from the almond so these almonds are now safe for eating. This removal only occur through mutation. Mutation is the sudden change occur in the DNA of cell that leads to different functions occur in the body so we can say that some mutation that is occur in organisms are beneficial.
