Which level of organization includes all the other levels of organization? organ system organism tissue cell

Answers

The correct answer is Organism. Organisms are made out of numerous organ systems that work together and these systems are made out of various organs. Organs are made out of tissues of all kinds, while tissues are made out of various cells that each serve their function. It is like clock and everything works perfectly unless something breaks.

The level of organization that includes all the other levels of organization is the organism level.

Further Explanation:

The human body is organized at different levels, beginning with the cell followed by tissue, organ, organ system and finally the complete organism. With every upgrade of level, the complexness will increase.

The lowest level of organization is the cell. Cell is the structural and practical unit of life. The complexness of a cell is the least as compared to the other levels of organization. A cell generally consists of flexible membranes that enclose protoplasm, a water-based cellular fluid beside a range of small functioning units referred to as organelles.

A group of cells with similar structure performing a function represent the tissue. A tissue has a lot of complexness than a cell and contains a specific function additionally.

A group of 2 or a lot of kinds of tissue with similar structure and performance makes up an organ. The complexness and functionality upgrades within the organ as compared to the tissue. Every organ performs one or a lot of specific physiological functions.A cluster of organs that work along to perform major functions or meet physiological needs of the body maybe called as the organ system.

Finally, a bunch or organs playing similar functions form up the organ system followed by several organ systems together creating up a complete operating organism. The highest level of organization is the organism level. an organism may be a living being that contains a cellular structure which will severally perform all physiological functions necessary forever.  

So, organism is the level of organization that features all the other levels of organization.

Which macromolecule is the primary energy source for organisms?Question 2 options:
A) Sunlight
B) Protein
C) Fat
D) Carbohydrate
E) Nucleic acid

Answers

The correct option is D.
Carbohydrate is the main energy source for living organism. When carbohydrate food are consumed, the digestive enzymes break the carbohydrate down to glucose. The body cells use glucose as a source of fuel to produce energy which they use for their metabolic activities.

Natural selection acts by taking advantage of natural variations in the traits of organisms within a population what is the ultimate source of this variation

Answers

The answer is the mutations within the genetic code. 

Natural selection is one of the basic mechanisms of evolution by which species adapt to their environment in order to increase their chance of survival and reproduction. In natural selection, genotype variations that will increase the chance of survival and reproduction of some organism are preserved and will be inherited. But, the sources of this genotype variations are not changes in the environment, nor response to the stress, but the mutations in the genome of the organism. If a mutation is not lethal, it could remain in the population, increasing the variation is some traits.
