Answer:
You can determine its genotype by crossing it to an animal with a recessive genotype, llbb.
Explanation:
A test cross is performed when there is an individual with an unknown genotype and we desire to know if it is a heterozygote individual or a dominant homozygote individual.
The cross occurs between the individual of unkown genotype and a recessive homozygote individual.

Answer: Endocrine
A chemical signal produced in the pituitary gland at the base of the brain binds to a receptor on liver cells. This signal would be classified as an endocrine signal.
Explanation:
An endocrine signal is produced by a cell that targets a distant cell through the bloodstream.
Hence, a endocrine signal (carried by hormones) produced at the base of the brain (usually an endocrine gland) travels through the bloodstream to the target cell and binds to a receptor on the liver, and then exerts its function.

In contrast, genetic drift produces random changes in the frequency of traits in a population. Genetic drift arises from the role chance plays in whether a given individual will survive and reproduce. One definition of a species is a group of organisms that can reproduce with one another and produce fertile offspring.
