Answer:
3.) Cellular respiration
Explanation:
During cellular respiration, the energy stored in glucose is transferred to ATP.
During this, glucose, in the presence of oxygen, is converted into carbon dioxide and water.
glucose + oxygen → carbon dioxide + water.
During this process, the energy stored in glucose is transferred to ATP.

What is the best way to describe our current understanding of the one-gene/one-polypeptide hypothesis
Answers
Answer:
It applies to prokaryotes but not to eukaryotes.
Explanation:
one-gene/one-polypeptide hypothesis is based on the idea that there is a structurally complex gene whereby each gene encodes a single polypeptide, that either operates on its own or under a relatively more complex protein.
However, based on the existing findings and research, the one-gene/one-polypeptide hypothesis "applies to prokaryotes but not to eukaryotes."
This is because one gene/one-polypeptide cannot be used to explain different spliced versions found in several eukaryote organisms

Pore Protein:
Glycoprotein:
Channel protein:
Answer: -Forms a pone for movement of water -Transports ions -Used for identification of cells -Receptors for the cell -2 layers that limit what enters or leaves the cell
Answers
Answer:
Phospholipid bilayer: layers that limit what enters or leaves the cell
Fibrous Protein: Receptors for the cell
Pore Protein: Transports ions
Glycoprotein: Used for identification of cells
Channel protein: Forms a pone for movement of water
Explanation:
Phospholipid bilayer is consist of two layers, interior layer is hydrophilic (water loving) and exterior layer is hydrophobic (water hating). This layer functions as a selectively permeable membrane and allows only required materials into the cell.
Fibrous Protein is one of the type of protein and act as cell surface receptor. for example: collagen and fibronectin act as cell surface.
Pore Protein are beta barrel proteins that creates pores for the ions to diffuse across the cell.
Glycoproteins are located on the surface of the lipid bilayer and act in cell-cell recognition and bind to the cell after recognizing or identifying properly for further procedure.
A channel protein is a channel in he cell membrane that is made up of amino acids. It forms a hydrophilic gateway for water and small, polar ions.
Hence, the correct answer is:
Phospholipid bilayer: layers that limit what enters or leaves the cell
Fibrous Protein: Receptors for the cell
Pore Protein: Transports ions
Glycoprotein: Used for identification of cells
Channel protein: Forms a pone for movement of water
Why does the thermosphere have the highest temperature of alle
atmosphere layers?
O A. It has the least gas particles.
B. It is closest to the sun.
C. It contains the ozone layer.
D. It is the thinnest layer.
Answers
Answer: B.
Explanation:
The thermosphere is most directly affected by the Sun’s radiation.
The thermosphere have the highest temperature of alle atmosphere layers It is closest to the sun.
What is Thermosphere?A portion of the Earth's atmosphere known as the thermosphere is situated precisely above the mesosphere and under the exosphere. It stretches from around 90 km (56 miles) to 500–1,000 km above the surface of our planet.
In the lower thermosphere temperatures rise dramatically before leveling off and remaining rather constant as altitude rises above that point. The thermosphere's temperature is significantly influenced by solar activity.
In general, the thermosphere is around 200° C hotter during the day than at night, and about 500° C hotter during periods of high solar activity.
Therefore, The thermosphere have the highest temperature of alle atmosphere layers It is closest to the sun.

Glaciers are masses of ice that move that move slowly on land. Which of these features was most likely formed by a glacier?
f. a wide valley
g. a deep ocean
h. a lava flow
j. a mountain range
Answers
Answer:
A deep ocean
uhhh yeah I just have to type this part so it send anyways hope this helps!
The feature that was most likely formed by a glacier is a deep ocean. The correct option is g.
What are glaciers?A glacier is a vast, perpetual accumulation of crystalline ice, snow, rock, silt, and sometimes liquid water that forms on land and travels down a slope due to its own weight and gravity.
Melting glaciers contribute to rising sea levels, which increases coastal erosion and storm surge as warming air and ocean temperatures produce more frequent and intense coastal storms such as hurricanes and typhoons.
Surface wind-driven currents cause upwelling currents, which combine with landforms to form deepwater currents. Currents can also be caused by temperature (thermo) and salinity (haline) variations in water masses, a process known as thermohaline circulation.
Therefore, the correct option is g. a deep ocean.
