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
Yes it is therefore the answer is true
Answer: D
Explanation: The important thing to notice in this question is that it's asking for the FORMATION of a NEW species. That detail automatically removes B as the answer, because, while an invasive species <em>could </em>lead to a new species, it isn't likely, and there's the fact that B is talking about the INTRODUCTION of a species that already exists.
A could be correct, but fertilizer isn't likely to lead to a new species, as well as C, which would lead to a LOSS in species and biodiversity.
D is correct because it is an example of Allopatric Speciation, which is when one species converges into 2 species because of a physical barrier.
I hope this helps. Have a great week!
