Explanation:
DNA contains phosphorus, but protein does not. Protein contains sulfur, but DNA does not. This allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

In the DNA structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.
What is Hershey and Chase experiment?Hershey-Chase experiment was the final experiment which is also called as the Waring Blender experiment. In this experiment, they showed that phages only injected their DNA into host bacteria, and that the DNA served as the replicating genetic element of phages.
They used this experiment to prove that DNA is the genetic material. [tex]T_2[/tex] Bacteriophage that was grown in isotopic medium radioactively labels a specific viral component. Two types of isotopic media were used.
Viruses that were grown in radioactive sulfur (35S) contained radiolabeled proteins.Viruses grown in radioactive phosphorus (32P) had radiolabeled DNANext, the virus was allowed to infect a bacterium (E. coli) and the virus and bacteria were then separated through centrifugation. After centrifugation, the larger bacteria formed a solid pellet, while the smaller viruses remained in the supernatant. The pellet of bacteria was found to be radioactive when infected with 32P-virus (DNA), but not with 35S-virus (protein).
This provided proof that DNA was the genetic material because DNA had been transcribed into bacteria, not proteins.
Thus, in the DNA structure there is phosphorus present while protein does not contain phosphorus but it contains sulfur while DNA does not which allowed radioactive phosphorus and radioactive sulfur to identity each molecule specifically.

How are the nervous systems of a flatworm and a fish different?
One has a brain with a forebrain, a midbrain, and a hindbrain, and the other has ganglia in which integration can occur.
One has nerve cells with axons and the other does not.
One responds to stimuli in the environment and the other does not.
One is a loose network of connected neurons without centers of integration, and one has ganglia in which integration can occur.

Answer:A flatworm has a simple nervous system with two nerve cords running down both of its sides. ... While a fish's nervous system is comprised of a central brain and a spinal cord along with many branching nerves, which allows them to sense things around them
Explanation:
A flatworm has a very mild nervous system with pair nerve cords moving down each side. It has two single brains called ganglia, which are pure packages of nerves. ... Fish have extremely advanced nervous systems organized around a brain.

What is the difference between weathering and erosion? (Site 1).
Answer:
Weathering and erosion are natural geological processes that act like rocks and soil on the earth's surface, moving and reshaping the earth. Weathering is the breaking down of rocks into smaller pieces by changing the size and structure of the rocks. The forces of nature are largely responsible for this process. Erosion involves processes such as wind, water flow, and ice movement, which results in change from one place to another.

when preparing pure cultures, dilution is necessary for
Dilution is necessary during pure culture preparation to reduce the bacterial load and allow readable colonies to grow.
Dilution of bacteria culture is carried out in comparison to McCfarlan standard so as to have a decent number of bacteria that will not be too numerous or too little to observe the growth of distinct colonies during culture preparation.
Without dilution, colonies may form but may be too numerous to count. Too much dilution may also lead to no growth in the culture plates.

What is a lymph node?No lymph nodes exist in the central nervous system. The lymph nodes are more likely to gather in three locations on each side of the body.
The inguinal nodes in the groin, axillary nodes in the armpit, and cervical nodes in the neck are where these sites are found.
The typical lymph node is enclosed by a connective tissue capsule, which divides it into lymph nodules. The lymph nodules, which are dense aggregations of lymphocytes and macrophages, are divided by lymph sinuses.
Therefore, there are several locations throughout the node's perimeter where afferent lymphatics, which carry lymph there from the periphery and enter the node on its convex side, may be found.

How are seeds produced
Answer:
From other seeds
Explanation:
They grow more seeds form the one seed
Answer:
From plant reproduction.
Explanation:
Plants produce flowers to make seeds. To make a seed a flower must be pollinated. Pollen from the male part of one flower travels to the female part of another flower where the seeds are made. Most, but not all plants, have both male and female parts inside one flower. The stigma is usually in the centre and the stamens, which produce the pollen, cluster around it. The petals act like an advertisement to attract various animals, which will carry the pollen from one flower to another.

Answer:
Explanation:
Mesozoic Era, second of Earth’s three major geologic eras of Phanerozoic time. Its name is derived from the Greek term for “middle life.” The Mesozoic Era began 252.2 million years ago, following the conclusion of the Paleozoic Era, and ended 66 million years ago, at the dawn of the Cenozoic Era. (See the geologic time scale.) The major divisions of the Mesozoic Era are, from oldest to youngest, the Triassic Period, the Jurassic Period, and the Cretaceous Period. The ancestors of major plant and animal groups that exist today first appeared during the Mesozoic, but this era is best known as the time of the dinosaurs.

Which process occurs at location W? precipitation evaporation condensation transpiration.
Answer:
Precipitation
Explanation:
If it's the graph that I am thinking of, then it is precipitation. This is where raining occurs in he picture.
The biogeochemical cycle where the water circulates from the atmosphere to the Earth surface in a continuous motion is called the water or hydrological cycle.
The process that occurs at location W is:
Option A. Precipitation
The water cycle can be explained as:
The water cycle has four main components that are evaporation. condensation, precipitation and runoff.When an atmospheric substance falls on the ground in the form of rain, snow hails etc. are called precipitation.When the water from surfaces turns into vapours and moves upwards in the atmosphere is called evaporation.The vapours in clouds turn into water droplets ready to fall as rain or snow is called condensation.Transpiration is a plant function in which surplus water is exhaled from the stomata of the leaf.Therefore, the water cycle shows precipitation.
