The answer is 49.92%
Let's use the <span>Hardy-Weinberg principle:
p + q = 1
p</span>² + 2pq + q² = 1
<span>
where:
p - the frequency of dominant allele G
q - </span>the frequency of recessive allele g
p² - the frequency of homozygous dominant individuals GG with colour green
2pq - the frequency of heterozygous individuals Gg with colour green
p² - the frequency of homozygous recessive individuals gg with color brown
23% of the population is brown: p² = 23% = 0.23
p = √(p²) = √0.23 = 0.48
p = 0.48
p + q = 1
0.48 + q = 1
q = 1 - 0.48 = 0.52
<span>The percentage of the population that is expected to be heterozygous is 2pq:
2pq = 2 * p * q = 2 * 0.48 * 0.52 = 0.4992 = 49.92%</span>
Answer:
The correct answer is "the temperature is above 23 °C but not exceeding 40 °C".
Explanation:
The main function of virgin queens in a bee's hive is reproduction. Normally virgin queens do not exit the hive except to perform mating flight(s), which normally are done with 10–20 drone bees and then return to the hive as mated queen bees. Usually virgin queens perform her mating flight(s) in ideal temperature conditions, which are with a temperature above 23 °C but not exceeding 40 °C.
Answer:
UCS: sticks part of the toy into the electrical outlet
UCR: frightened and crying
CS: toy
CR: frightened to toy
Explanation:
Classical conditioning is a form of learning whereby a conditioned stimulus becomes associated with an unrelated unconditioned stimulus, in order to produce a behavioral response known as a conditioned response.
<u>Unconditioned stimulus</u> (UCS) is an agent that leads to a response without training. In this example, the child won't know that he can have electrical shock playing with toys.
<u>Unconditioned response</u> (UCR) is an automatic response to a UCS that's why the child starts crying and frightened.
<u>Conditioned stimulus</u> (CS) is a former natural stimulus that comes to elicit a given response after pairing with a UCS. In this situation, CS is when mom gives the same toys to the baby that was the reason for electrical shock.
<u>Conditioned response</u> (CR) is a learned response to a CS because the baby shows fear when he saw the same toys. It is his learned behavior.
A vertebrate-animal embryo gives rise to the centrum. The centrum is a bone that is part of the vertebral column. It is the hollow space within the vertebra that protects and contains the spinal cord. Within this hollow area are several nerves that send impulses to the brain enabling the organism to function and be at its homeostasis.
Answer:
Methemoglobinemia
Explanation:
Methemoglobinemia (also known as the blue baby syndrome), is a condition with multiple etiologies which is associated with the lack of oxygen in the blood. This syndrome affects the function of red blood cells by altering the amount of hemoglobin protein, which carries and distributes oxygen to the body. Methemoglobinemia may be acquired by exposure to drugs and/or toxins. In this regard, it has been shown that high levels of nitrates in the water may induce this syndrome in infants.
