This is true. In biology a key is used to identify a plant or animal.
These keys will depend upon certain characteristics that can be used to
determine which part of the animal kingdom an organism belongs to.
Answer:
The Genotype of a normal male wil be: XBY.
Explanation:
- A sex linked recessive disorder is expressed only in males because males have only one X chromosome and so only one allele for this gene can be present in them.
- Hence, if the recessive allele is present then colour blindness will occur.
- If the dominant allele is present then the male will be normal.
- XbY has a recessive allele so the male with this genotype will be color blind.
- XBYb cannot be aoption because Y chromosome cannot have the allele of the gene.
- XBXb is a female carrier's genotype.
- XBY has the dominant allele and so the man with this genotype will be normal.
The correct answer in this case is either b - find potential employees or also D - fire bad employees in worst case scenarios. It has already happened that an employee was fired because his employer found something he did not like about the employee on facebook. This was cause for him to fire him. On the other hand, the same is true of finding new candidates.
Answer:
Random variation in the population led to a population with a favorable adaptation
Explanation:
Insecticide resistance can be defined as an evolutionary process that causes a decreased susceptibility of an insect population to a particular insecticide. The evolution of the insecticide resistance occurs by the mechanism of natural selection, where most resistant insects survive and thus pass on their acquired heritable resistance to their offspring. Moreover, the evolutionary origins of the resistance trait may be associated with different processes: 1-<em>de novo</em> mutations (i.e., the emergence of beneficial genetic changes in the population), 2-standing variation in the original population which is selected under the selective agent (in this case, the pesticide), 3-migration of resistant specimens originally resistant to the pesticide, and 4-even interspecific transfer (i.e., horizontal transfer between different species).
