Keratin is an intracellular fibrous protein that gives hair, nails, and skin their hardness, strength, and water-resistant properties. The keratinocytes in the stratum corneum are dead and regularly slough away, being replaced by cells from the deeper layers
Hope this helped!
Good luck :p

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.
Eyyy we both Supreme!
Yo answer is A. Sorry about the wrong answer.
If the allele frequency of a gene for brown fur is increasing from 15 to 25 percent, the population of the bears is evolving.
Answer:
Option-D
Explanation:
Plants are the organisms present on the Earth which can be easily marked with their green color. The green color is due to the presence of the chloroplast which encompasses the chlorophyll pigment.
The chlorophyll pigment has the ability to capture the sunlight energy which initiates the process of photosynthesis. The photosynthesis process utilizes Carbon dioxide gas and water to form glucose molecules.
The glucose molecule is then transported to the other parts of the plants like stem and roots where photosynthesis is absent and to obtain the energy, plant perform cellular respiration. The cellular respiration requires oxygen gas which acts as an electron acceptor molecule.
Thus, Option-D is correct.
