How energy from the sun is absorbed in earths atmosphere
Answer:
Explanation:
About 23 percent of incoming solar energy is absorbed in the atmosphere by water vapor, dust, and ozone, and 48 percent passes through the atmosphere and is absorbed by the surface. Thus, about 71 percent of the total incoming solar energy is absorbed by the Earth system
Answer:
The earth-atmosphere energy balance is the balance between incoming energy from the Sun and outgoing energy from the Earth. Energy released from the Sun is emitted as shortwave light and ultraviolet energy. When it reaches the Earth, some is reflected back to space by clouds, some is absorbed by the atmosphere, and some is absorbed at the Earth's surface.

Eukaryotic cells contain complex organelles that carry out their chemical reactions. Prokaryotes
lack many of these complex organelles, although they have a variety of unique structures of their own.
However, most prokaryotic cells can exchange nutrients with the outside environment faster than most
eukaryotic cells. Why is this so?
A Most prokaryotic cells are smaller and have a higher surface-to-volume ratio than eukaryotic
cells.
B
Most prokaryotic cells are larger and have a higher surface-to-volume ratio than eukaryotic cells.

6. When scientists “culture” human cells what exactly does that mean?
Answer:
The process by which cells are grown under controlled conditions, generally outside their natural environment. After the cells of interest have been isolated from living tissue, they can subsequently be maintained under carefully controlled conditions.
Explanation:
It means that the human cells are being grown outside of the human body in controlled conditions.
Why are the Kreb's cycle and ETC
considered aerobic processes?
Answer:
Without oxygen, the electron transport chain becomes jammed with electrons. Consequently, NAD cannot be produced, thereby causing glycolysis to produce lactic acid instead of pyruvate, which is a necessary component of the Krebs Cycle. Thus, the Krebs cycle is heavily dependent on oxygen, deeming it an aerobic process.

what type of waste does the digestive system get rid of
help me fast lol this is a biology related question.
Answer:
A=5
B=9
C=3
D=4
Explanation:
3+2=A, so A must equal 5.
A+4=B, since we know A equals 5 then 5+4=B, therefore B must equal 9.
2+C=5, then use algebra to solve by subtracting 2 from both sides. C=3.
3+1=D, so D must equal 4.
Animal cells store extra glucose in the form of glycogen. Which molecule do plants use to store extra glucose?
A. glycogen
B. baleen
C. myosin
D. starch
Answer:
The Answer is Glycogen
Explanation:
It's Glycogen because Glycogen is a polysaccharide of glucose its structure allows it to pack compactly, so more of it can be stored in cells for later use.

A receptor site that a molecule can bind to that changes the shape of the active site is called a(n)
a) allosteric site
b) active site
c) disulphide bridge
d) MHC receptor
Answer:
a) allosteric site
Explanation:
An allosteric site is a site on an enzyme other than the active site where a molecule that is not a substrate binds. This changes the shape of the enzyme, making it harder for the substrate to bind and inhibits enzyme activity.
Hope that helps.
7. After the rumor spread that Henrietta’s cells took over many other cell cultures in research labs what did researchers want to do and why?
I WILL GIVE BRAINLIEST!
Researchers wanted to do research because they thought normal cells spontaneously became cancerous cells.
What are Henrietta's cells?The first immortal human cells to be generated in culture were from Henrietta Lacks. They are also known as Henrietta's cells. They were crucial in the creation of the polio vaccine. In the early space flights, they went up to investigate what would happen to cells in weightlessness.
Her cells have since been employed in numerous significant scientific breakthroughs, such as cloning, gene mapping, and in vitro fertilization.
After the rumor spread that Henrietta's cells took over many other cell cultures in research labs scientists wanted to do research, because they thought that normal cells are converting into cancerous cells.

Explanation:
Where are the hydrogen bonds located in water molecules?
А
between oxygen and hydrogen atoms in a water molecule
B
between the oxygen and hydrogen atoms of two different
water molecules
Answer:
B Is trueExplanation:
Hydrogen bonds locate between oxygen and hydrogen atom of different water molecules in water30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample.
Predict whether these concentrations would increase, decrease, or stay the same if nitrite-nitrifying bacteria were added to the sample.
If 30 grams of ammonia (NH3), nitrite (NO2-), and nitrate (NO3-) are added to a soil sample and nitrite-nitrifying bacteria are added, the concentration of the nitrate would increase, that of the nitrite would decrease, while that of ammonia would remain the same.
The process of converting ammonia to nitrate, also known as nitrification occur in two stages:
The conversion of ammonia to nitrite by ammonia oxidizing bacteria.The conversion of nitrite to nitrate by nitrite-oxidizing/nitrifying bacteria.Now, if nitrite-nitrifying bacteria is added to the soil sample above, it means that only the nitrite would be converted to nitrate. The bacteria will not be able to oxidize ammonia.
Hence, some of the nitrite would be converted into nitrate leading to the reduction in the concentration of the former, and an increase in the concentration of the latter. The concentration of ammonia will remain unchanged.
