I am pretty sure the answer would be "B".... HOPE THIS HELPS! please rate if it does!
Answer:
The five levels of organization are:
- Cells
- Tissues
- Organs
- Organ Systems
- Organism
Explanation:
Five Levels of Organization:
Cells:
Cells are the fundamental levels of organization of living organisms. They are the basic structural and functional units of life. Cells are composed of different organelles that perform various functions and through division of labor, accomplish different cellular tasks. E.g, muscle cell, neuron (nervous system cells), nephron (specialized kidney cells) etc.
Tissues:
Cells that perform similar functions combine together to form tissues. For example, skeletal muscle tissue, cardiac muscle, vascular tissue etc.
Organs:
Organs are complex structures formed by the combination pf two or more types of tissues that perform specific but related functions. E.g, heart (pumps blood, contains cardiac muscle tissue), brain (conducts nerve impulses, contains neural tissue).
Organ Systems:
Organ systems are a combination of organs that perform related functions and work together to perform specific physiological functions. E.g, circulatory system (contains heart and circulatory system).
Organism:
This is the highest level of organization. An organism is a combination of cells, tissues, organs and organ systems that all work together to perform specific physiological functions.

The answer should be each has 23 chromosomes.
The normal somatic (body) cells in human should have 46 chromosomes, which is also 2 complete set. All the cells in our body should have 46 chromosomes each (unless other rare cases), however, except our gametes (cells for reproduction, sperms/eggs). This is because, in fertilization, a sperm and an egg will fuse together to produce a zygote, if both sperm and egg have a chromosome number of 46, the zygote would have doubled chromosomes, which is impossible.
So, in order to help restore the correct number of chromosomes in zygotes/offsprings, the gametes only have half of the chromosomes (23 in human) comparing to other somatic cells such as bone cells or skin cells. These cells with only half of the chromosomes can be called haploid cells, and they're usually produced by a cell division process called meiosis.
Splicing<span> is the cutting of some parts of the </span>RNA<span> resultant of the transcription (pre-</span>mRNA<span>) turning it</span><span> into a mature </span>messenger RNA<span> (</span>mRNA<span>). The parts that are cut off are called </span>introns<span> and will not have a part on the translation. When splicing does not take place in a certain site, intron will not be removed there and that will affect how mRNA will be then translated.</span>
