RNA differs from DNA in the type of a) purines & pyrimidness b) sugars & Purmes c) sugar & pyrimidness. dl pyrimidness (please give right answer only)
Answer:
There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

Hope it is helpful....what are the effects of the even on each of the Earth's four spheres?
Answer:
An event can cause changes to occur in one or more of the spheres, and/or an event can be the effect of changes in one or more of Earth's four spheres. This two-way cause and effect relationship between an event and a sphere is called an interaction.
How will a solution change if a base is added?
The hydroxide ion concentration will decrease and lower the pH.
The hydroxide ion concentration will decrease and raise the pH.
The hydrogen ion concentration will increase and lower the pH.
The hydroxide ion concentration will increase and raise the pH.
Answer:
As the concentration of hydrogen ions in a solution increase, the more acidic the solution becomes. As the level of hydroxide ions increases the more basic, or alkaline, the solution becomes. ... Thus, as the hydrogen ion concentration increases hydroxide ion concentration falls, and vice versa.
Thank you

explain what density is. How is it different from weight and mass?
Hey there! I'm happy to help!
Density is how much mass there is per amount of space. The formula for it is mass divided by the volume. How much mass is there per (per means divide) amount of space?
Think of it like a room in a house. If the room only has one person, it isn't going to be very dense with people because there is only one person in the entire room. If there were 100 people, it would be very crowded in that room and the whole room would weigh a lot more. If we make our room the size of a huge convention hall though, 100 people wouldn't make it very crowded,. and it would be less dense. So the amount of people (mass) and the size of the room (volume) affect density.
In that sense, density is kind of like how crowded a thing is.
A hollow watermelon has less density than one that isn't because a watermelon that isn't hollow has more substance inside of it (more mass).
Mass is a factor of density because it measures how much of something there is. It can be related to the people in the room.
Weight is mass but with gravitational influence. A watermelon in space is going to weigh less than a watermelon on Earth because in space there is no gravity and it is floating around, but it will still have the same density just like our room full of people would still be crowded even if the people weighed nothing and were floating around.
On Earth though, we measure mass with terms like pounds, kilograms, etc. We use the term mass over weight because it is more scientifically accurate when calculating density.
Have a wonderful day and keep on learning! :D

Use the image below to answer the question.
The illustration shows the mitochondrial intermembrane space. Molecules enter and exit enzymes. Molecule upper N upper A upper D upper H passes through enzyme upper N upper A upper D upper H Reductase releasing upper H superscript + baseline and upper N upper A upper D superscript + baseline. A blue arrow starts at upper N upper A upper D superscript + and goes through enzyme Ubiquinone then enzyme Cytochrome Reductase, an upper H superscript + baseline is released. The arrow continues through enzyme Cytochrome c and enzyme Cytochrome Oxydase, another upper H superscript + baseline is released. The formula 2 upper H + one-half upper O subscript 2 baseline is to the left of enzyme Cytochrome oxydase with an arrow pointing to the other side. The arrow meets with the arrow from upper N upper A upper D superscript + baseline at upper H subscript 2 baseline upper O. To the right is upper A upper T upper P synthase, upper A upper D upper P + upper P subscript 1 baseline have an arrow going under upper A upper T upper P synthase, an upper H superscript + baseline arrow points to the arrow, the result is upper A upper T upper P.
Which step of cellular respiration is shown in the image?
glycolysis
lactic acid fermentation
electron transport chain
Krebs cycle
Answer:
electron transport chain
Explanation:
just took the quiz
The image shows the C. electron transport chain (ETC) step of cellular respiration
What is the electron transport chain ?The ETC is the final stage of cellular respiration, where oxygen is used to create ATP. NADH and FADH2, which are produced in the Krebs cycle, donate electrons to the ETC.
The electrons are passed through a series of proteins, which release energy that is used to pump protons across the mitochondrial membrane. This creates a proton gradient, which is used to power ATP synthase to produce ATP
The Krebs cycle and lactic acid fermentation are both earlier steps in cellular respiration. In the Krebs cycle, pyruvate is oxidized to produce NADH, FADH2, and ATP. In lactic acid fermentation, pyruvate is converted to lactate, producing NADH.

Answer:
A TISSUE is a group of connected cells that have a similar function.
In order to test the effects of a new drug, you isolate the messenger RNA molecules from both treated and untreated eukaryotic cells and separate them according to size using gel electrophoresis. In each lane of the gel, the shorter RNA molecules migrate more quickly through the gel and end up near the bottom of the gel while the longer RNAs migrate more slowly and remain near the top.
The samples that were loaded into each of the four lanes are as follows:
Lane 1: the primary RNA transcripts isolated from the nucleus of untreated cells
Lane 2: the primary RNA transcripts isolated from the nucleus of cells treated with the drug being tested
Lane 3: RNA isolated from the cytosol of untreated cells
Lane 4: RNA isolated from the cytosol of cells treated with the drug being tested
Which of the following conclusions is most likely to be CORRECT?
A. These results suggest that the drug affects RNA processing.
B. These results suggest that the drug digests DNA.
C. These results suggest that the drug inhibits DNA replication.
D. These results suggest that the drug contains a protease that targets this gene product.
E. These results suggest that the drug inhibits post-translational processing of this gene.

Describe the general temperature of ocean currents near the equator and the poles.
Answer:
Currents flowing away from the Equator are generally warm.
Explanation:
That is because the Equatorial regions is the source of warm air and water. Ocean currents flowing from the Equator thus carry this warm water with them. The most prominent example is the Gulf Stream in the Atlantic Ocean, which runs most of the way to the North Pole and brings mild winter climates in its wake to adjacent coastal areas. In the Pacific Ocean the Alaska Current likewise carries warm water northward making Anchorage, Alaska much milder in winter than inland areas with the same latitude.

why velocity is regarded as a vector quantity?
Answer:
Because velocity has magnitude and direction, speed is not a vector quantity since it only has magnitude
For example, if a car is moving backwards with a speed of 40m/s
Your velocity is - 40m/s
Speed is 40m/s
How is nuclear energy generated?
Answer:
Nuclear energy is generated either by Fission of a nucleus into two or more fragments , or by Fusion of two nuclei into one. The nuclear energy is used to superheat steam and then drive a rotor axle inside a generator and then generate electricity.
Answer:Nuclear power comes from nuclear fission
Explanation:Nuclear power plants heat water to produce steam. The steam is used to spin large turbines that generate electricity. Nuclear power plants use heat produced during nuclear fission to heat water. In nuclear fission, atoms are split apart to form smaller atoms, releasing energy.

What is the process of nitrification?
Bacteria converts ammonia into nitrites and nitrates that plants can use.
Fungi convert nitrogen in dead plants into ammonium, which converts proteins into ammonia.
Nitrogen is converted into a useable form through lightning fixation.
Plant enzymes reduce nitrogen compounds into amino acids.
Answer:
Bacteria converts ammonia into nitrites and nitrates that plants can use.
Nitrification is a microbial process by which reduced nitrogen compounds (primarily ammonia) are sequentially oxidized to nitrite and nitrate. Ammonia is present in drinking water through either naturally-occurring processes or through ammonia addition during secondary disinfection to form chloramines.
