Soil
Soil is the upper layer of the ground comprising of a mixture of sand, silt, clay, loose rock fragments, and organic matter that can support the growth of rooted plants. The relative proportions of sand, silt and clay determine the texture and size of the pores of the soil, which affects its ability to allow air and water to penetrate/infiltrate.
A nested selection structure can appear in either an outer selection structure's true path or its false path.

Answer:
C. Incomplete dominance
Explanation:
According to the given information, the phenotype of the heterozygous genotype is different from either of the homozygous genotypes. This means that it is not complete dominance. The heterozygous genotype has one-half the number of receptors and expresses the phenotype that is intermediate of two homozygous genotypes. This is an example of incomplete dominance. In incomplete dominance, the phenotype of the heterozygote is distinct and is intermediate of two homozygotes. This occurs since none of the alleles is completely dominant over the other.
Answer: The correct answer is- c. They do not live in the extreme environments.
Cell membrane ( also called plasma membrane) surrounds the cytoplasm of all cells and separates the internal environment of cell from its external environment. In bacteria, it is composed of phospholipids and many protein.
- Phopholipids are linked to ester in case of bacterial cell membrane whereas in archaebacteria, they are linked to ether ( that is they are linked to glycerol backbone).
The ether linkage in the cell membrane of Archaebacteria forms stable membranes that enable them to survive under harsh environmental conditions such as hot springs, boiling mud surrounding volcanoes, salt lakes,
Bacteria do not live under such conditions. Thus, bacteria lack ether-linked cell membranes.
