How did Hershey and Chase use radioactivity to draw a conclusion about proteins and DNA?
Hershey and Chase studied bacteriophages which are viruses that attack bacteria. They labeled the bacteriophage with radioactive isotopes to see where it goes when a virus attacks.
What is Hershey and Chase experiment?They discovered that nearly all the radioactivity was found in phosphorus, confirming that DNA contains genetic material, not protein.
The final experiment, also known as the Waring Blender experiment, in which Hershey and Chase demonstrated that phages only injected their DNA into host bacteria and that the DNA acted as the replicating genetic element of phages, is the Hershey-Chase experiment that is most well-known.
Hershey and Chase discovered proof that phages introduced their DNA into host bacteria in the prior experiment.
Therefore, Hershey and Chase studied bacteriophages which are viruses that attack bacteria. They labeled the bacteriophage with radioactive isotopes to see where it goes when a virus attacks.

Explanation:
One easy way to make seeds germinate faster is to presoak them for 24 hours in a shallow container filled with hot tap water. Water will penetrate the seed coat and cause the embryos inside to plump up. Don't soak them for longer than 24 hours because they could rot. Plant the seeds immediately in moist soil.

Explanation: My explination for this is teeth are important and needed to be taken care of.
Answer:
Hygiene is a series of practices performed to preserve health.
According to the World Health Organization, "Hygiene refers to conditions and practices that help to maintain health and prevent the spread of diseases." Personal hygiene refers to maintaining the body's cleanliness.
Many people equate hygiene with 'cleanliness,' but hygiene is a broad term. It includes such personal habit choices as how frequently to take a shower or bath, wash hands, trim fingernails, wash clothes, and basically self care. It also includes attention to keeping surfaces in the home and workplace, including bathroom facilities, clean and pathogen-free. Many people know without taking care of your teeth the food would leave many bacteria and without flossing it, it can lead to the food between your teeth to get bad causing a cavity, then tooth decay.

Plants take in carbon dioxide and release gas
Answer:
yes, but by gas you mean oxygen right?
Explanation:
Answer: During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

One of the reasons that nutrients in a vegetable patch might be considered abiotic is:
The nutrients are gotten from the soil and they are decomposeAccording to the given question, we need to give one reason why the nutrients in a vegetable patch can be considered an abiotic factor.
As a result of this, we can see that the nutrients in a vegetable patch can be considered as an abiotic factor because they are already decomposed.
An abiotic factor in an ecosystem is any non living thing which has a direct (or indirect) impact on the living things in an ecosystem.

Suppose you are determining the growth rate of two species of plants. Species A is 25 cm tall and grows 3 cm per month. Species B is 10 cm tall and grows 8 cm per month. Which system of equations models the height of each species H(d) as a function of days d. H(d) = 25 + 3d H(d) = 10 + 8d H(d) = 3 + 25d H(d) = 8 + 10d H(d) = 25 + 3d H(d) = 8 + 10d H(d) = 2 + 8d H(d) = 25 + 10d
Answer:
H(A) = 25 + 3m and H(B) = 10 + 8m
Explanation:
Let H(A) is the height of species A as a function of months m while H(B) is height of species B as a function of months m.
For Species A,
H(A) = 25 + 3m
For species B,
H(B) = 10 + 8m
Hence, this is the required solution.
1. Consider the following food chain.
grass
deer
wolf
If the deer population increases, explain what could happen to the grass population
Most likely the grass population will decrease and the wolf population will increase.
Eventually it should level out again though.
If the population of deer will increase will result in the decrease in grass quantity.
What is a food chain?A food chain is a linear network of links in a food web that begins with producer organisms and ends with an predator, detritivores, or decomposer species.
A food chain also shows how organisms are related to one another through the food they consume. Each extent of a food chain represents a distinct trophic level.
Overgrazing occurs when there are too many deer in a given area, resulting in the loss of brush and shrubs in forested areas. The absence of undergrowth means that small animals and birds have no place to shelter and nest.
As a result, many native species are becoming extinct because they no longer have access to the habitat they require.
Thus, the grass population will decrease as a result of increase in deer population.

1. The St. Lucie River drains Lake Okeechobee into the Atlantic Ocean.
What is the relationship among the parts of this system?
Answer:
The St Lucie canal serves as an outlet of drainage for the Okeechobee Lake through the St Lucie River and out to the Atlantic Ocean.
Explanation:
The St. Lucie River is an estuary in Florida, in the United States. It was basically a freshwater system before an inlet was dug to provide access directly to the Atlantic Ocean.
Lake Okeechobee is the second largest freshwater lake in the United States. Water flows into the lake from various sources with Kissimmee River being the major source.
Because of the high levels of water in Lake Okeechobee, the St. Lucie canal was constructed in the 1920s. The St. Lucie canal provides a good outlet from the Okeechobee lake, through the St. Lucie River and out to the Atlantic Ocean.
Regulation of body temperature in humans is most closely associated with the
A) production of gametes
B) evaporation of sweat
C) absorption of carbon dioxide
D) production of hydrolytic enzymes
Answer:
b
Explanation:
Regulation of body temperature in humans is most closely associated with the evaporation of sweat that is present in option B, as the higher the body temperature, the more sweat is needed to maintain homeostasis.
What is the need for homeostasis in the body?The body maintains a particular internal temperature irrespective of changes in the external environment, and this is possible because of the homeostasis in the body, which is important because many of the body's processes are temperature and pH sensitive, such as the enzymatic function, the alkalinity of blood, etc.
Hence, regulation of body temperature in humans is most closely associated with the evaporation of sweat that is present in option B, as the higher the body temperature, the more sweat is needed to maintain homeostasis.

A student performed an experiment by placing the de shelled egg in a concentrated salt solution for 5 minutes.What changes did he observe in the egg?Name the process
Answer:
the egg begins to shrink
Explanation:
During the 5 minutes that the egg is in the concentrated salt solution he would notice that the egg begins to shrink. This occurs due to the process known as osmosis which happens when a solvent passes a semipermeable membrane towards where there is a higher concentration which in this case would be within the egg. Since the egg would contain more water than the salt solution causing it to shrivel and shrink.

Which goes where ? Mitosis Vs. Meiosis
Answer:
Mitosis, Meiosis, and both are written below
Explanation:
Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas
This is because mitosis occurs in body cells and is used for growth, so all the daughter cells are the same.Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages
This is because meiosis occurs in gametes and is used in reproduction.Both: Chromosomes need to replicate before the whole process begins, a form of reproduction
This is because both are reproducing (they are dividing) and DNA must be replicated so each daughter cell has it.an entire DNA molecule is split down the middle and the bases on each side are used as a pattern for a new strand when DNA is
