In an important experiment, a radioactively labeled bacteriophage was allowed to infect bacteria. In a first trial, the phage contained radioactive DNA, and radioactivity was detected inside the bacteria. Next, phage containing radioactive protein was used, and the radioactivity was not detected inside the bacteria. These experiments led to the conclusion that:_____.
A) DNA is made of nucleotides.
B) genes carry information for making proteins.
C) the genes of this phage were made of DNA.
D) bacteriophages can infect bacteria.
Answer: C) the genes of this phage were made of DNA.
Explanation: the experiment described above wherein a radioactively labeled bacteriophage was allowed to infect bacteria ultimately led to the conclusion that the genes of the bacteriophage under study were made of DNA (a biopolymer of deoxyribonucleic acid, which is a type of nucleic acid composed of four different chemical groups, called bases: adenine, guanine, cytosine and thymine). Simply put, the experiment shows that the genetic material of the phage is DNA.
Which energy source uses heat from underground?
O A. Nuclear
O B. Geothermal
O C. Solar
O D. Hydroelectric
Answer:
The answer is geothermal (b)
The correct answer is B. Geothermal.
This is true because geo relates to the earth and thermal relates to heat.
When you put those two words together, it means heat from the earth.
A is incorrect since the energy sources comes from the fission or splitting of atoms.
C is incorrect since solar energy relates to heat or energy from the sun.
D is incorrect since hydro means water and therefore hydroelectricity is an energy source that is made from water.

Mice living on a granite hillside have coloration ranging from light to dark. The surfaces of the granite rocks are either very dark or very light. Dark mice hiding on dark patches are difficult to see and light mice hiding on light patches are equally camouflaged. Mice with gray fur can be seen everywhere and are preyed upon more heavily. What kind of selection is this?
Answer:
Disruptive selection.
Explanation:
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population. There are different types of natural selection: sexual selection, stabilizing selection, directional selection, frequency-dependent selection, and disruptive selection.
The disruptive selection causes an increase in the two types of extreme phenotypes over the intermediate forms. Limits between one extreme and the other are frequently very sharped. Individuals belonging to one phenotype can not live in the same area as individuals belonging to the other phenotype, due to the traits differences between them, competition, predation, etcetera.
In the proposed case, each population of mice is adapted to its environment: one of them is dark-furred as the color of the dark patches it lives on, and the other population is light-furred as it lives in light patches. These adaptations are probably related to survival strategies and help them to avoid predators as they camouflage with the substrate.
Both extreme phenotypes have been favored over intermediate forms, resulting in the development of two groups with very marked differences. Grey-furred mice population belongs to the intermediate phenotype which can be seen everywhere and be preyed upon more heavily. Disruptive selection does not favor this phenotype.
Disruptive selection can lead to speciation, driving to evolution. This is why it is also called "diversifying selection".

A fine-grained igneous rock forms
Choice B is the right option since the cooling is fast.
The minerals may not have enough room to develop owing to a sudden cooling and therefore their structure is delicate and glassy. The composition of an igneous rock depends on how quickly the magma is cooled when the volcanic eruptions occur. Slow cooling allows big crystals to grow while rapid cooling allows tiny crystals to appear.

Resistance is a force that Resistance is a force that is always higher than blood pressure. never changes in a blood vessel. acts with pressure to move blood along a vessel. decreases blood flow. increases blood flow.
Answer:
decreases blood flow.
Explanation:
I'll assume the question is about one of the effect of blood flow resistance.
Resistance forces are those forces that opposes the flow of blood through the blood vessels. Resistance forces in the blood vessels changes with the diameter of the blood vessels, and always acts against pressure to move the blood against the blood vessels. If the resistance forces in the blood becomes equal or greater than the blood pressure, there will be no blood flow through the blood vessels. So generally, resistance forces in the blood vessels acts to decrease blood flow through the blood vessels.
Which statement correctly compares the pH of water to that of other substances?
he pH of water increases as its temperature increases, while other substances have a stable pH.
The pH of water is neutral; it is higher than the pH of acids and lower than the pH of bases.
Water contains more hydrogen ions than most other substances, giving it a higher pH.
Water is neutral and has a pH of 0; acids have a pH greater than 0, and bases have a pH less than 0.

What will most likely increase if there is a high death rate? immigration emigration birth rate population
Answer:
Emigration
Explanation:
If there is a large number of deaths, then the population would move onto another area to find a mate, more food, and to be together to protect themselves from danger
The component of population that will most likely increase with a high death rate would be emigration.
When the death rate shoots up in a particular environment due to certain factors, organisms are bound to emigrate away from such environment to avoid death from reaching them.
It is a natural instinct of every living organism to respond to stimuli. A high death rate is a stimulus that organisms would want to move away from.

3) Two students decided to repeat the Hershey and Chase experiment, with modifications for a science competition. They radioactively tag the nitrogen of the DNA, rather than the phosphate. Each nucleotide has only one phosphate and two to five nitrogen atoms, the strategy of labeling the nitrogen atoms would detect a stronger signal than labeling the phosphates. Why won't this approach work
Answer:
Explanation:
In the Hershey and Chase experiment, they aimed to show where the phage DNA went when it exited the protein coat and entered the bacteria. In this scenario, the two student's approach won't work because amino acids (and therefore all proteins) also have nitrogen atoms which ultimately means that the radioactivity would not distinguish between DNA and proteins and the experiment will not provide the correct results.

Answer:
Option A is the most appropriate answer.
Explanation:
The arrangement has plants being drenched in a water container to discharge Oxygen gas that is freed and gathered in a tube placed previously. The volume of gas gathered can be utilized to find out the rate of photosynthesis and whenever coupled by methods for pH observing gadget, an expansion in pH which shows soluble alkaline means that more oxygen yield. Along these lines, this method can be utilized to then again check CO2 levels. The gas syringe is utilized to permit the oxygen gas bubbles to be gathered at the known for evacuation and estimation purposes.
This photosynthometer is combined with a hydrogen carbonate indicator evaluating CO2 levels. At neutral levels in comparing with different cases, the shading is orange and there is a progressive change to yellow shading is CO2 focus is high. At low focus, the shading turns out to be a lot darker (purplish).
