Answer:
Cells --> Tissues ---> Organs --> systems
Explanation:
There are four levels of organization of life in organisms. These are the cells, tissues, organs and systems.
- Cells
This is the first and simplest level of organization of life. Cell is the smallest unit of body of living organisms. Examples of cells are rod and cone cells in the eyes, nerve cells, red blood cells etc
- Tissues
A tissue is the second level of organization of life. It is a group of similar cells forming a layer in an organism which performs a particular function. Examples of tissues include blood and muscles
- Organs
An organ is the third level of organization of life. It is a group of similar tissues forming a layer which performs a specific function. Examples of organs in the body include skin and eyes
- System
An system is the fourth level of organization of life. It is a group of similar organs which work together to perform specific functions. Examples of systems in the body of animals include nervous and digestive system. The systems then work together to make up the body of an organism.
Thus, the correct order from the most simplest to the most complex is:
Cells --> Tissues ---> Organs --> systems
Answer: one offspring out of the four will have a recessive-recessive genotype.
Explanation: A cross between two parents who are heterozygous for a gene that has a simple dominant-recessive pattern of inheritance will produce four offsprings: one will be homozygous dominant, two will be heterozygous dominant while one will be homozygous recessive.
Homozygous dominant offspring has two dominant alleles, heterozygous dominant offspring has one dominant allele and one recessive allele while a homozygous recessive offspring has two recessive alleles.
For example, a cross between two parents that are heterozygous (Tt) for tall will produce one TT, two Tt and one tt. TT is homozygous dominant, Tt is heterozygous dominant and tt is homozygous recessive. An offspring with genotype tt has a two recessive alleles thus have a recessive-recessive genotype. Therefore the number of offsprings with recessive-recessive genotype is one.

Dictionary Definition:
"Any of a large group of organic compounds occurring in foods and living tissues and including sugars, starch, and cellulose. They contain hydrogen and oxygen in the same ratio as water (2 : 1) and typically can be broken down to release energy in the animal body."
Explanation:
In stem cell therapist ,Osteoblast cells are the most likely type of cell that will be injected. Cells called osteoblasts produce bone. They achieve this by generating a matrix that becomes mineralized, increasing bone mass. This kind of cell injection will promote quick bone repair.
Our patients and readers typically experience a few waves of shock when learning about stem cells, particularly stem cell therapy.
Realizing that stem cells are a natural component of our body rather than some new, miraculous innovation is the first major epiphany. To put it very broadly, each and every one of us was once nothing more than a few stem cells.
The second surprise comes when you discover that stem cells can be extracted from your body and can differentiate into a variety of mature cells that your body requires for regeneration and healing.
When you understand that this isn't some sci-fi movie plot and that tens of thousands of patients are now living proof, you experience a third wave of shock.
