Answer:

Conditioned response.

Explanation:

Conditioned response may be defined as a type of learned behavior used in the Pavlov experiment. This type of response mainly generated when the neutral stimulus get mixed with the strong stimulus.

The male quail can be sexually arouse by red light. The red light here acts as the conditioned response because the neutral stimulus (red light) when mixed with the unconditioned stimulus result in the presentation of the female quail and increases the response of the male quail.

Thus, the correct answer is conditioned response.

During transcription, enzymes bind to a molecule of DNA. Then, the enzymes unwind and separate the DNA's double helical strands.
stich3 [128]
MRNA or messenger RNA. As the central dogma of biotech goes, DNA is transcribed to mRNA which is translated to tRNA, after which the amino acids form peptide bonds and form proteins. So when you see transcription, the first thing you think of is DNA to mRNA.

A 20-pound object is dropped from a 50-foot bridge onto the ground below it. A 50-pound object is dropped from a 100-foot cliff
ira [324]

The 50 pound object will reach the ground first.

Explanation:

Using the second equation of motion, we can derive the time taken for each of the object to reach the ground. As the object is thrown from the top of the bridge or cliff, acceleration due to gravity will be acting on them.

So, s = ut+\frac{1}{2} at^{2}

The value of s for the object thrown from 50 foot bridge is given as 50 ft. The initial velocity of the object will be zero. The acceleration can be written as the ratio of mass to gravitational force.

Then, s = (0) t +\frac{1}{2}*\frac{m}{F}*t^{2}

50 = \frac{20}{2F} t^{2} \\\\t^{2} = \frac{100F}{20}

t = \sqrt{5F}

Then, consider the time taken for the 50 pound object to reach the bottom of 100 ft cliff as t₁ and the displacement in this case is 100 ft.

Then, 100 = (0)t +\frac{1}{2}*\frac{50}{F}*t_{1}^{2} \\\\t_{1}^{2} =\frac{200F}{50}

t_{1} =  2 \sqrt{F}

Since, the gravitational force acting on both the objects will be same, the ratio of time taken is

\frac{t }{t_{1} }=\frac{\sqrt{5F} }{2\sqrt{F}} = \frac{\sqrt{5} }{2}

So, the time taken for the 20 pound object to reach the ground of 50 ft bridge is √5 s =2.236 s and the time taken for the 50 pound object to reach the ground of 100 ft cliff is 2 s.

Thus, the 50 pound object will reach the ground first.

Explain why the scientists used the cytoplasm from the donors egg
gavmur [86]

It assures the insemination process because the cytoplasm contains the organelles ( mitochondria, Golgi apparatus, cytoplasmic reticulum etc. ). It is the go-between and transfers information between each organelles. Also, cytoplasmic transfer includes proteins, and mRNA along with the cytoplasm (and its organelles) to be taken from the donor egg.

Match each hazardous waste with its matching description.
Sphinxa [80]

Matching each hazardous waste with its description is shown below :

<u>Hazardous waste                            description</u>

Asbestos : substance known to cause lung cancer; found in older landfills

Mercury : Substance found in computer monitors that causes brain damage

Cadmium: Hazardous cancer agent found in the batteries of many devices

Lead :  Substance from thermostats known to cause reproductive issues

Too much exposure to these hazardous waste always leave a negative effect on the health of individuals, Asbestos are used in the roofing of older buildings and can be found in older landfills. the fiber from asbestos affects the Lungs ( alveoli ) of humans which might lead to lung cancer.

Mercury are used for PC's backlight and also in the mother board of modern computers too much exposure to mercury can lead to brain damage.

Cadmium are hazardous cancer causing agent used in making industrial batteries, prolonged exposure to lead poses several health risk which includes reproductive issues because lead can cut across placenta barrier between a pregnant woman and unborn child.

Hence we can conclude that matching each waste to its description is as

Asbestos : substance known to cause lung cancer; found in older landfills

Mercury : Substance found in computer monitors that causes brain damage

Cadmium: Hazardous cancer agent found in the batteries of many devices

Lead :  Substance from thermostats known to cause reproductive issues
