Answer:

Hershey Chase  and Griffith experiment supported the same conclusion which was: DNA is the molecular substance of genetic inheritance.

Explanation:

Both experiments have was based on different phenomenon and techniques to prove same conclusion.

Hershey and chase conducted an experiment via bacteriophage which consists to DNA and protein coat that infects bacterial cells. He proved the DNA as genetic material by the help of transduction mechanism (Incorporation of Bacteriophage DNA in to bacterial cells). He used two group of Bacteriophage 1st group of Phage contain radioactively labelled proteins by Sulphur 32 isotope. While 2nd group contain Bacteriophage having P32 labelled DNA to infect Bacterial cells. After the infection, the Reaction tubes subjected to centrifuge and presence of radioactivity was determined in pellet and supernatant. The 1st group show radioactivity in supernatant while 2nd group shows racdioactivity in pellet or bacterial cells.

Griffiths just hypothesized a substance that can be transmitted from dead organism to alive organisms with the help of transformation phenomenon (uptake of Genetic material from the surrounding or environment). He conducted his experiments on <em>Streptococcus pneumonia avirulent and virulent species. </em>By mixing dead virulent species and live avirulent species and injecting into the mice results in the death of an experimental animal. While alone dead virulent species and live avirulent species fail to cause disease in mice.

Receptors that are especially important for helping a person maintain balance are located in the (A) gyrus cinguli (B) inner ear
Lera25 [3.4K]

The receptors that aid in allowing a person to maintain balance are located within the inner ear.

The human ability to walk upright without falling, and a wide variety of other tasks that we perform as all thanks to our ability to maintain balance. This ability is given to us by structures located deep within the inner ear.

The inner ear is located deep within the lateral side of the head. This ear contains 3 semicircular canals or ducts, which are tiny structures filled with liquid. Each of these canals has an expansion at its end known as the ampulla, which holds within it the very small cellular balance receptors called crista.

Describe an experiment to investigate the effect of training on subjects ability to run faster without respire get anaerobically
Zinaida [17]
A runner HAS to use the anaerobic respiration process,first we need to know the difference between anaerobic respiration and aeorobic respiration 

<span>Anaerobic respiration is done by burning glucose directly without the presence of oxygen giving out lactic acid and energy </span>
<span>Aerobic respiration is done by burning glucose and oxygen giving out water + engergy + Co2 </span>

<span>1.) Take a stop-watch </span>
<span>2.) Take TWO or more runners </span>
<span>3.) Unlike Olympic race match ask ONE of the runners to run their fastes and the others to GRADUALLY speed up </span>
<span>4.) make the runners breath hard for air </span>
<span>5.) after finish line </span>
<span>6.) do a test of Lactic through urin test or use Lactometer (don't ask me how to use it 'cause I don't know lol) </span>
<span>7.) check the concerntration </span>
<span>8.) whoever has the LOWEST concerntration,take that runner time for running and meter to find speed you'll be able to spot out who has used aerobic respiration during the race</span>

What type of environmental conditions do the camera systems need to withstand for three years?
nikklg [1K]

Cameras and video-shooters are essentially tough. They can withstand a lot, from insects to shark bites. However, in order to withstand being outside for such a long time of three years? That's a little tricky.

As we all know, the batteries can corrode if left in damp places, or if left in for too long. Therefor, this can't be damp. Nowadays, most cameras have plastic in various places, so leaving it somewhere hot could inevitably melt it. You don't want that. If your camera is left in the cold, (18°F, 10°C) then the batteries could be severely changed. If left in a cold place, the battery life could deplete by so much as half, so in very cold climates, you will very quickly run out of power.

In order for it to sustain 3 years, you will probably need to find a climates that is about 60°F (15.5556°C) in a drier location.

I hope this helped!
