Answer:
D) Evolutionary relationships
Explanation:
Taxonomy is the science and study of classifying organisms based on their shared characteristics. In other words, how organisms are grouped and named based on what they have in common with each other. While this may include some feeding behaviors and habitats, the evolutionary relationships are what truly determine organisms' classifications and how related they are to each other.
Answer:
Inducer or the ligand
Explanation:
The operon is a sequence of genes present on the DNA which is controlled by the single promoter and are activated or switched on only when required otherwise switched off.
The Operon system is influenced by the molecule present in the environment called the ligand or the inducer like lactose which when binds to the repressor molecule changes the confirmation of the repressor molecule as a result of which the repressor molecule is released from the operator site and the operon is turned on.
Thus, inducer or ligand is correct.
Answer:
Explain how genes are expressed for a particular trait?
Genes are expressed phenotypically as it reflects through dominant gene which are represented through physical means such as height, skin color, shape e.t.c
Explanation:
Answer:
Bedrock
is most likely found in Dhorizon.
Explanation:
In R horizon Bedrock material is most likely to be found. The parallel layer to the surface of the Earth is known as the Soil Horizon. It is different from other layers of Earth’s surface in terms of chemical, biological and physical characteristics.
Among the all soil profiles r horizon is mainly known for composition of hard rock masses. It is a layer which has partially withered or completely un-withered rocks at its base. It is similar to the parent material.
