Habitat
Explanation:
Habitat is a given area where organisms interact with non-living things.
The dwelling place of living organisms is their habitat and it is the produced as a result of interaction between the organism and non-living components.
- The habitat of an organism defines its niche in such an environment.
- This is related to the roles which organisms perform in the ecosystem.
- Ecosystem is the interaction between organisms and the non-living components with their environment.

compound consisting of a nucleoside linked to a phosphate group. Nucleotides form the basic structural unit of nucleic acids such as DNA.
Answer:
The answer will be pyramid of biomass.
Explanation:
As it goes up the pyramid, the number decreases.
Answer:
b) By mixing weak base with its conjugate acid and then adjusting the pH with strong acid.
Explanation:
Hello,
In this case, considering that the buffer required a pH greater than 7 where the basic conditions are present, we need a weak base and its conjugate base in order to assure such pH greater than 7. Moreover, by using a strong acid, we can gently add it in order to decrease the pH up to 7.4 via a properly measured neutralization of the necessary moles of base up to a hydrogen concentration of 3.98x10⁻⁸ (pH). Therefore, answer is b) By mixing weak base with its conjugate acid and then adjusting the pH with strong acid.

The limitations of cell size are:
1) Surface area to volume ratio
2) Nucleo cytoplasmic ratio
3) Fragility of cell membrane
What are the cause of limitations on cell size?
The need for a surface area of sufficient area to allow the cells function→.
→If the surface area of cell increase volume increase to the cube of the linear increase.
→ Nuclie contains information needed for protein synthesis . Some cells reduce this limitation to increase the no. Of nucleus called multinucleated.
Examples are muscle cells.
