Let's assume you are conducting an experiment to determine the effect of a new drug on the incidence of epileptic seizures. You

select 20 epileptics from the 150 epileptics being treated at a nearby hospital and administer the drug to them. You record the number of seizures in each of the 20 subjects for one month. Then you record the number of seizures in each of the 20 subjects for one month without the drug. Being compulsive, you also record the number of seizures for the remaining 130 epileptics for one month. The number of seizures for each of the 130 epileptics constitutes

Answer:

data

Explanation:

Data collection for the remaining 130 ensures accuracy. it makes the investigator to determine the effects or interaction  of the drug( the dependent variable ) in each of the  130.That is  how the drug exhibited it effects on epilepsy in wide range of patients, the response of each patients, so that its potency  can be determined. if the drug actually have any  effect on epilepsy or it was due to some other physiological effects in the subjects. Thus accurate effects of the drug(dependent variable) can be determined from  the observation of ranges of data collected .

Ringing in the ears is called:
Elza [17]

Answer:

c. tinnitus

Explanation:

Tinnitus (a hearing impairment) is a form of  hearing of sound when no external sound is present Which is often described as a Ringing,Tinnitus may also sound like a clicking or roaring. i.e usually unclear voices or music are heard. The sound may be soft or loud, low or high pitched, and appear to be coming from one or both ears. Ranging from one person to another, the sound may causes depression or anxiety and can interfere with concentration.

Otitis externa is a condition that causes inflammation , the inflammation also covers  (redness and swelling) of the external ear canal, i.e the tube between the outer ear and eardrum.

Meniere's disease popularly called (MD), is a disorder of the inner ear that is characterized by episodes of feeling like the world is spinning (vertigo), hearing loss, and a fullness in the  ear. The cause of MD involves both genetic and environmental factors. Some of the factors include constrictions in blood vessels, viral infections, and autoimmune reactions.

Otosclerosis is a condition where one or more foci of irregularly laid spongy bone replace part of normally dense enchondral layer of bony otic capsule in the bony labyrinth. This condition affects one of the ossicles (the stapes) resulting in hearing loss, vertigo or a combination of symptoms.

Therefore from the foregoing we can conclude that Tinnitus is the correct anwser.

How is laying eggs on land an evolutionary advantage for sea turtles and capelin
gregori [183]

1. Laying eggs on land reduces the chances of the eggs being predated on by predators in the seas and oceans.  

2. Temperatures are critical in the development of the yolk into an embryo and full turtle. Temperatures even determine the sex of the developing turtles. Land heats up more than water hence promotes faster development hence increases the survival of the offsprings.

A student conducts an experiment. He mixes two chemicals in a beaker at 30 ° Celsius. Then, he repeats the experiment at 45 ° Ce
Salsk061 [2.6K]

The most likely conclusion the student will make would be that increasing temperature increases the rate of reaction.

<h3>Effects of temperature on reaction rates</h3>

The rate of reaction of a system is directly proportional to the temperature of the system.

This is because the kinetic energy of the reactant's molecules is increased by increasing the temperature of the system. Thus, reactant molecules collide more and this leads to more reactions.

Thus, increasing the temperature of a system moderately also increases the rate of reaction in the system. Too much increase in temperature, however, can destroy the structures of reactants.
