Answer:
The options are:
A. operant conditioning
B. classical conditioning
C. innate behavior
D. imprinting
E. altruistic behavior
The correct answer is A. operant conditioning.
Explanation:
The rat's behavior is learned, an example of conditioned behavior.
In operant conditioning, the behavior is committed to memory via the adoption of reward or punishment. In these case study, the rat conditioned behavior is to manoeuvre the maze to get its reward: food.

Listed are several examples of types of animal behavior. Choose the letter of the correct term (A-E) that matches each example in the following questions. operant conditioning classical conditioning innate behavior imprinting altruistic behavior Through trial and error, a rat learns to run a maze without mistakes to receive a food reward.
Answer:
Please find the expected genotypes and phenotypes of the progenies of each cross below.
Explanation:
In the MN blood-group locus of the gene, alleles LM and LN exhibit codominance i.e one allele is not dominant or recessive to the other, hence, they are both expressed when they occur in a heterozygous state (MN).
Considering the following crosses (find the punnet square attached);
a)LMLM x LMLN - The progeny are LMLM and LMLN in the genotypic ratio 1:1. Phenotypic ratio is Blood type M (1) : blood type MN (1)
b) LNLN x LNLN - The progeny are all LNLN offsprings with a phenotypic and genotypic ratio 4:0. All offsprings will have a blood type N (4)
c) LMLN x LMLN - The progenies are LMLM, LMLN and LNLN in the genotypic ratio 1:2:1 respectively. The phenotypic ratio is Blood type M (1) : L
Blood type MN (2) : Blood type N (1)
d) LMLN x LNLN - The progeny are LMLN and LNLN with genotypic ratio 1:1 and phenotypic ratio blood type MN (1) : blood type N (1)
e) LMLM x LNLN - The progeny are all LMLN offsprings with penotypic ratio blood type MN (4)
The hormone calcitonin, which is produced by the parafollicular or C cells of the thyroid, has the opposite effect on blood calcium levels as does PTH. I hope this helps! : )
The X symbol looks too much like the multiplication symbol, it also makes using it as a variable more confusing.
