Therefore the volume of the stone is 5ml and the density is 4mg/ml.
What is Displacement Method ?The displacement method can be used to accurately measure the volume of the human body and other oddly shaped objects by measuring the volume of fluid displaced when the object is submerged.
It is given in the question that the initial volume of the water in the graduated cylinder is 20 mL.
When the stone was dropped in the cylinder, the water level rose to 25 mL.
The volume of the stone has to be calculated using the displacement method.
The volume displaced by the stone is 25-20 ml
= 5 ml
Therefore the volume of the stone is 5ml.
The density of any substance can be calculated by dividing its mass with its volume.
Mass given is 20g and the volume of the stone is 5ml
Therefore density = 20/5 = 4 gm/ml
Therefore Option A is the correct answer.

Which planet in our solar system has enough oxygen in the atmosphere to support life but temperatures that are too extreme? Answer choices -Uranus -all of these planets have oxygen -Venus -Mercury Neptune
Answer:
Jupiter.
Explanation:
Planet Jupiter is the planet in our solar system which has enough oxygen in the atmosphere to support life but the environmental conditions are too extreme. The temperature in the clouds of Jupiter is about -145 degrees Celsius which is equals to -234 degrees Fahrenheit). There may be plenty of oxygen available in the ocean of Jupiter to support life about a hundred times more oxygen than previously estimated.
Which occurs just before a volcanic eruption?
Most of the time a earthquake happens
their was no choices so hope this is what you were looking for
have a great rest of your day :)
Explanation:
To expand on the other persons answer, before an eruption the area around the volcano will most likely start experiencing earthquakes or tremors, this is because magma and chunks of rock are pushing through the earths crust. Other things are also common, such as hot springs near the soon to erupt volcano may change in temperature or new hot springs may form.
Which product of photolysis is needed for the continuation of the light reactions?
Answer:
Here, NADP+ is the final electron acceptor, which becomes reduced to NADPH. Meanwhile, ATP is also formed. Therefore, these light reactions release oxygen as a waste product of photosynthesis, while ATP and NADPH are essential to the next step in photosynthesis, the dark reactions.
Plants are able to engage in photosynthesis because they produce a chemical that can
absorb sunlight to synthesize glucose. What is this chemical?

C. Carbon Dioxide
D. Water
Answer:
B. Chlorophyll
Explanation:
Plants engage in photosynthesis with the help of chlorophyll.
In the process : Carbon dioxide is used and oxigen is produced.

explain why giving antibiotics to animals can affect human health
Answer:
Abstract. The use of antibiotics in food animals selects for bacteria resistant to antibiotics used in humans, and these might spread via the food to humans and cause human infection, hence the banning of growth-promoters.

question in pic! will give brainliest
Answer:
denitrification
Explanation:
Denitrification occurs when N is lost through the conversion of nitrate to gaseous forms of N, such as nitric oxide, nitrous oxide and dinitrogen gas. This occurs when the soil is saturated and the bacteria use nitrate as an oxygen source. De-nitrification is common in poorly drained soils.

what is it called when Corals feed off the byproducts of a microscopic algae living within their own tissue, called zooxanthellae. The photosynthetic activity of the algae is vital to the survival of the coral animals, which use the energy to extract calcium from the seawater and build their calcareous skeletons. The zooxanthellae are protected by the hard coral and obtain plant nutrients from the coral
Answer:
The correct answer is - mutualism.
Explanation:
Like it is given here, The coral gives a protected environment for algae and other compounds algae required for photosynthesis. Photosynthesis performed by the algae provides a byproduct of microscopic algae.
These algae produce oxygen and help the coral to remove wastes and algae is important to the survival of the coral animals, which use the energy to extract calcium from the seawater and build their calcareous skeletons.
Jeffrey wants to lose weight by using caffeine to
help with exercise. He asks himself, Which
caffeine drink will raise the heart rate the most?"
He tries to test this out by comparing the heart
rates of his neighbors, 3 brothers who are
triplets. One of the brothers drinks Pepsi,
another drinks a double shot of espresso (which
is coffee with twice the normal amount of
caffeine) and a third brother drinks only water for
comparison.
Jeffrey finds out that the triplet with the double
shot of espresso had the highest heart rate.
4. What is the independent variable for this experiment?
Answer:
Caffeine.
Explanation:
The independent variable for this experiment is the amount of caffeine because there is no effect on the caffeine in the experiment while on the other hand, weight loss is dependent variable which affects due to the amount of caffeine. Independent variable are those which can't depend on any variable in the experiment and can stay independently. There is no effect on the amount of caffeine so we can say that it is an independent variable.

Since the 2 strands of DNA are antiparallel to on another, DNA must be replicated both continuously and dis-continuously. The side of DNA that is replicated dis-continuously is done so in small parts called___________.
Answer:
Since the 2 strands of DNA are antiparallel to on another, DNA must be replicated both continuously and dis-continuously. The side of DNA that is replicated dis-continuously is done so in small parts called okazaki fragments.
Explanation:
OKAZAKI FRAGMENTS - Okazaki fragments are short DNA nucleotide sequences (roughly 150 to 200 base pairs in eukaryotes) that are synthesized in a non-linear fashion and then linked together by the enzyme DNA ligase to form the lagging strand during DNA replication. They shape short double-stranded DNA sections when combined with the lagging template strand.
The primosome initiates Okazaki fragments by generating a new RNA primer. To restart DNA synthesis, the DNA clamp loader releases the lagging strand from the sliding clamp and reattaches the clamp to the new RNA primer. DNA polymerase III will then synthesize the segment of DNA.
Reiji Okazaki, Tsuneko Okazaki, and their colleagues first found Okazaki fragments in 1968 while researching bacteriophage DNA replication in E. coli.
