Answer:
Option D, erosion, deposition, compaction, cementation
Explanation:
Sedimentary rocks are formed from the eroded soil. Therefore, erosion is the first step in formation of sedimentary rocks.
The eroded soil or rock is carried by carrier agents such as wind, water etc. and deposited at some place where it gets compacted under its own weight. After deposition and compaction, physio-chemical processes take place to produce chemical bonding between the deposited granular particles. Chemical interactions causes cementation of the compacted material
Hence, option D is correct
Answer:
Decomposition is the process by which dead organic substances are broken down into simpler organic matter such as carbon dioxide , water and mineral salt
Danish scientist Hans Christian Gram devised a method to differentiate two types of bacteria based on the structural differences in their cell walls. In his test, bacteria that retain the crystal violet dye do so because of a thick layer of peptidoglycan and are called Gram-positive bacteria. In contrast, Gram-negative bacteria do not retain the violet dye and are colored red or pink. Compared with Gram-positive bacteria, Gram-negative bacteria are more resistant against antibodies because of their impenetrable cell wall. These bacteria have a wide variety of applications ranging from medical treatment to industrial use and Swiss cheese production.
Answer:
biological macro-molecules
Explanation:
Answer:
A homologous pair
Explanation:
In determining the expression trait of humans, this is based on the homologous chromosomes. This in turn comprised of alleles otherwise known as homologous alleles. The homologous loci are thereby located in these alleles which served as the formation of traits when combined.
Hence, normally, A HOMOLOGOUS PAIR is required to determine the outward expression of a trait?
