I believe the answer would be "Top Predators"
I claim light, water and minerals are the limiting factors that might affect the growth or diversity of our ecosystem.
Abiotic factors are the non-living components of an ecosystem and include light, minerals, water etc. These are the vital components without which an ecosystem cannot exist.
Light is essential not only for photosynthesis in plants, but also in maintaining a livable temperature on Earth. Day and night cycles affect and form all the organisms as well as the interactions between them .
Water in itself makes possible the process of photosynthesis in plants as well as the majority of chemical processes in living organisms. Furthermore, makes possible the absorbtion of soil nutrients by the plant roots. Without water, life would not be possible.
Minerals are trace elements that exist in all living organisms and are vital to the existance of life. They can be found in both organic and inorganic combinations and are responsible for the existance and functioning of all mental and physical processis. They are most important in maintaining all physiological process as well as acting as catalysts for many biological reactions.
Ecosystems are complex systems that are built on complex interactions between organisms and their physical environment. In order for any life to exist, certain conditions and requirements need to be fulfilled. Among these, light, water and minerals are vital to the existance of life. Without these three, life as we know it would not be possible. They shape both the ecosystem and the organisms living in a certain area. Their abundance dictates both the growth and diversity of our ecosystem.
Answer:
Barr bodies are small bodies that are dark staining bodies that show the inactivated X chromosome, these sex chromatin bodies attach to the membrane of the nucleus of interphase cells.
One less of the total number of X-chromosome (n-1) represents the number of Barr bodies.
Then,
The number of Barr bodies with Klinefelter would be:
Klinefelter (47,XXY): (n-1) = (2-1) = 1 Barr body as here two X chromosome present.
Similarly, for
Turner (45,XO): (n-1) = (1-1) = 0 Barr bodies (X chromosome = 1)
Now, as per the question, the bar bodies for karyotypes given
47,XYY: (n-1) = (1-1) = 0 Barr bodies
47,XXX: (n-1) = (3-1) = 2 Barr bodies
48,XXXX: (n-1) = (4-1) = 3 Barr bodies
