Homeostatic regulation usually involves a(n) ________ that detects a particular stimulus, and a(n) ________ that responds to the
geniusboy [140]

Answer:

c) receptor; control center; effector.

Explanation:

Homeostasis maintains the internal body conditions almost constant. It includes specific cells that sense any deviations of internal or external conditions from the normal range. These cells are called receptors. The sensory information from the receptors is delivered to the control center. The central nervous system mainly serves as a control system wherein sensory information from the receptors is processed. The control center commands muscles and/or glands to perform desired responses to restore the homeostasis. Here, muscles and glands serve as effectors.

For example, thermoreceptors sense the rise of body temperature and the brain (control center) commands sweat glands (effectors) to produce sweat.

What is the probability that a hybrid individual with the genotype AabbCcddEeFf will produce a gamete that has the genotype abCd
PSYCHO15rus [73]

Answer:

6.25%

Explanation:

Find the number of different gametes that can be produced

number of gametes produced = 2^n

n is the number of allele pairs that are heterozygous

there are 4 heterozygous allele pairs, these are: Aa, Cc, Ee and Ff

2^4 = 16

abCdeF is one of the 16 genotypes that could be produced

to find the percentage, divide 1 and 16 and multiply by 100

1 ÷ 16 = 0.0625

0.0625 × 100 = 6.25
