Answer:
B. It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment.
Explanation:
Hershey and Martha Chase used radiolabeled the DNA of some of the bacteriophage cells with phosphorus (32P). They radiolabeled the sulfur (35S) of the coat protein in the second batch of the phage cells. They infected some of the bacterial cells with phage having radiolabeled DNA while the other <em>E. coli</em> cells were infected with the phage carrying radiolabeled coat protein. This allowed the clear identification of the radiolabelled molecule (DNA or protein) present in the host cell.
They observed that the <em>E. coli </em>cells infected with phage having radiolabeled DNA exhibited the radioactivity while the other batch of the host cell did not show it.
Answer:
In order photosynthesis to occur, plants need: water, nutrients, air, water, light, temperature, space, and time.
Explanation:
The answer is oil.
The United States' fossil shortage of oil makes the country dependent on outside sources. Mineral oil such as crude oil or commonly known as petroleum came from the ancient fossilized organic materials. This resource is limited. The US is now facing a shortage in oil and becoming dependent to some countries such as middle-east countries.
The organism belongs to domain Eukarya since it is multicellular, but its under kingdom Plantae, beacause its makes it own food and plants do that by doing photosynthesis
The most responsive of the three different types of cones to various light wavelengths. When light is present, a cone may become entirely depolarized if the sunlight is of a wavelength that is not optimal.
<h3>What do
the eye's rods and cones do?</h3>
Rods are in charge of seeing in dimly lit environments (scotopic vision). They have poor spatial acuity and do not integrate color vision. Cones are responsible for color vision, high spatial acuity, and activity under higher light levels (photopic vision).
<h3>In the eye, how many rods are there?</h3>
The total number of rods inside the human retina (91 million) is significantly higher than the total number of cones, despite the fact human perception of average daytime ambient light is dominated by cone-mediated vision (roughly 4.5 million). As a result, over the majority of the retina, rod density is substantially higher than cone density.
