explain how a carrier protein can facilitate the diffusion of glucose or other substances into the cell.
Specific chemicals are bound by carrier proteins and transferred on one side of the membrane. The conformational changes they go through next enable the molecule to cross the membrane and exit on the other side.
How carrier protein facilitate the diffusion?
When a molecule diffuses, it usually moves from a high concentration location to a low concentration area until the concentration is the same everywhere in the space.
Contrary to channel proteins, another form of membrane transport protein that is less selective in the molecules it transports, carriers are proteins that move a particular material through intracellular compartments, into the extracellular fluid, or across cells. Carrier proteins are found in lipid bilayer cell structures such cell membranes, mitochondria, and chloroplasts, just like other membrane transport proteins.
Therefore, carrier proteins can facilitate the diffusion of glucose or other substances into the cell.

over 90% of urinary tract infections (utis) are caused by escherichia coli strains. utis are 14 times more common in women than in men. why do you think this is
Urinary tract infections are 14 times more common in women than men because a women's urethra is shorter than a man's. So bacteria can easily enter the urinary bladder.
What are urinary tract infections?
It is an infection that occurs in any part of the urinary system including the kidneys, ureters, bladder, and urethra. These are mostly caused by bacteria that enter the urethra and bladder which causes inflammation and infection.
Most of the urinary tract infections occur in the lower urinary tract- the bladder and the urethra.
Symptoms of urinary tract infections include:
A strong urge to urinate that doesn't go awayA burning feeling when urinatingUrinating often and small amountsUrine looks cloudyUrine appears red, bright pink that gives signs of blood in urineStrong-smelling urinePelvic pain in womenDrinking plenty of liquids mostly water leads to urinating more often and allowing bacteria to be flushed from the urinary tract before an infection can begin.

B.) it’s an extrusive rock and cooled slowly at the rock
C.) it’s an intrusive rock and cooled rapidly below the surface
D.) it’s an intrusive rock and cooled slowly below the surface
Based on the information, the student can conclude that granite is an intrusive igneous rock and cooled slowly below the surface.
What are igneous rocks?
One of the three primary rock types, along with sedimentary and metamorphic rocks, is igneous rock, also known as magmatic rock.The cooling and solidification of magma or lava results in the formation of igneous rock.The planet's crust or mantle may partially melt existing materials to produce the magma. A rise in temperature, a fall in pressure, or a change in composition are typically one or more of three processes that lead to melting. Extrusive rocks form on the surface or intrusive rocks form below the surface as a result of solidification into rock.Intrusive refers to igneous rocks that have solidified and cooled below the surface. Rocks that are intrusive to a pluton are also referred to be plutonic. A pluton is an intrusive rock body made of igneous material that has cooled within the crust. The cooling of magma inside the Earth happens gradually. Large crystals can form because of slow cooling, which is why intrusive igneous rocks can be seen to include crystals. Most intrusive igneous rocks are made of granite.

In the phenomenon of wilted lettuce leaves became fresh after soaking in cold water is also known as osmosis.
How is osmosis process?Re-freshing lettuce through cold water, called by osmosis process. this phenomenon happen because lettuce has a more concentrated medium and has a higher hypoosmotic pressure, so that water is absorbed into the lettuce.In a more general explanation, lettuce itself consist of >80% water content, besides that lettuce is a leaf-shaped plant and has high evaporation of water through natural openings, the width of the leaves owned by this lettuce affects the rapid rate of evaporation of water and the wilting process. The natural opening mechanism that occurs is also influenced by temperature, air, and humidity. At increased temperatures, the openings that occur will be larger so that the decay process takes place more quickly and vice versa. Therefore lettuce becomes fresh when soaked in cold water.However, this method cannot be implemented on all vegetables, especially on vegetables that do not go through the wilting process before rotting.Learn more about osmosis here: brainly.com/question/10260811

The two particles that pass through proteins that are part of the inner membrane of a mitochondrion are electrons and hydrogen ions. The correct options are B and D.
What is mitochondria?Mitochondria are membrane-bound cell organelles that produce the majority of the chemical energy required to power the cell's biochemical reactions.
The outer mitochondrial membrane, in contrast to the inner membrane, is permeable to small molecules. This is due to the presence of porin proteins, which form channels that allow free diffusion of molecules smaller than about 6000 daltons.
Hydrogen ions in the matrix space can only pass through the inner mitochondrial membrane via ATP synthase, a membrane protein. ADP is converted to ATP as protons pass through ATP synthase.

Provide a possible mechanism for why the muscle was unable to maintain a prolonged contraction during fatigue.
Muscles can't sustain prolonged contractions during fatigue because muscles can run out of energy (ATP), so ATP production will be diverted by anaerobic means. The anaerobic process will produce more lactic acid, so lactic acid will accumulate and diffuse into the blood fluid.
What causes muscle fatigue other than lactic acid buildup?Several opinions explain the onset of muscle fatigue, including:
Lactic acid accumulation is the cause of muscle fatigue.Due to the accumulation of free H+ derived from the hydrolysis of ATP and anaerobic glycolysis in exercising muscles.In increasing exercise intensity, energy is mainly obtained from the hydrolysis of ATP and anaerobic glycolysis. Both of these processes produce free H+. With the increasing intensity and demand for ATP, the process of anaerobic glycolysis and ATP hydrolysis increases. In this condition, there is an increase in the concentration of H+ ions from anaerobic glycolysis and ATP hydrolysis, and if the buffering capacity of the cells is exceeded, the accumulation of free H+ will cause muscle fatigue.
