Semipermeable cell membranes are made of phospholipids that form a bilayer. What major benefit does this arrangement of the membrane provide to the cell?.
Answer: Phospholipid bilayers are critical components of cell membranes. The lipid bilayer acts as a barrier to the passage of molecules and ions into and out of the cell. However, an important function of the cell membrane is to allow selective passage of certain substances into and out of cells.

The correct optimal temperature fore the the sun-zyme substrate complex is 37°C and the temperature in which it will be denatured is 75°C and 100°C.
What is an Enzyme?This is referred to as a biological catalyst which is used to speed up the rate of reactions in the body. It is proteinous in nature and is substrate specific which means various types can only act on certain biological substances.
They are easily denatured by heat which leads to them losing their structure and function and not being able to act on the substrate. The optimal temperature for enzyme action in the body is 37°C.
A higher temperature such as 75°C and 100°C will lead to the denaturing of the enzymes which will therefore lead to no gas being produced thereby making it the correct choice.

following is a cost benefit analysis regarding the removal of arsenic ( a poison) in water. Consider the costs and benefits, chose a side and explain why you chose the side that you did.
cost: this requires a vast array of treatment technologies with detailed specifications. it will cost companies $60-70 million dollars to implement the changes. the companies will raise the price of their product drastically to counteract their expenses, making every day items more expensive for you.
benefits: millions of dollars will be saved on potential health problems. Associated bladder and lung cancer instances will drop. this will lower the environmental impact on the ecosystem
Considering the costs and benefits, it is best to remove arsenic from the water, as the savings in population health and quality of life are greater than the cost of this operation.
What can arsenic do to health?Prolonged exposure to arsenic in water and food can cause cancer, skin damage, developmental problems, heart disease, diabetes, and damage to the nervous system.
How to get arsenic out of water?Currently, the most commonly used process to remove arsenic is to run potable water over the activated alumina (aluminum oxide) surface on which the arsenic is adsorbed. Reverse osmosis can also be used for arsenic removal.
With this information, we can conclude that arsenic It can be absorbed orally and through the airways, its lethal dose is 0.07g/kg, bioaccumulative, practically all arsenic compounds are toxic to the human body. Its acute or chronic exposure and concentration are often monitored by urine tests.

The physical process by which water and solute move through a membrane when a hydrostatic pressure gradient exists across the membrane is the process of:_____.
The physical process by which water and solute move through a membrane when a hydrostatic pressure gradient exists across the membrane is the process of Osmosis.Osmosis takes place in keeping with the awareness gradient of water throughout the membrane, that is inversely proportional to the awareness of solutes.
Water actions throughout mobileular membranes through diffusion, in a procedure referred to as osmosis. Osmosis refers specially to the motion of water throughout a semipermeable membrane, with the solvent (water, for example) transferring from a place of low solute (dissolved fabric) awareness to a place of excessive solute awareness.
Osmosis is the diffusion of water via a semipermeable membrane in keeping with the awareness gradient of water throughout the membrane. Whereas diffusion transports fabric throughout membranes and inside cells, osmosis transports best water throughout a membrane and the membrane limits the diffusion of solutes withinside the water.

Of all the different types of dietary lipids, research shows that decreasing the intake of ______ has the most significant effect on lowering blood levels of ldl.
Of all the different types of dietary lipids, research shows that decreasing the intake of saturated fatty acids has the most significant effect on lowering blood levels of LDL.
Cholesterol is a steroid lipid that can be found in the cell membrane and is used in making steroid hormones. It is carried or transported around the body by substances called lipoproteins. There are two types of lipoproteins, HDL (High Density Lipoprotein) or the 'good cholesterol' and LDL (Low Density Lipoprotein) or the 'bad' cholesterol. Excess levels of LDL in the blood increases the risk of cardiovascular diseases.
Saturated fatty acid occurs naturally in cheese, butter, milk, beef, pork, palm oil and coconut oil. A large number of observational research and studies show that lowering the intake of saturated fatty acids has the most significant effect on lowering LDL levels in the blood. Studies also show that saturated fatty acids prevent LDL from being cleared or absorbed in the liver, leading to an increase in LDL in the blood. Hence, reducing one's intake of saturated fatty acids lowers the blood levels of LDL.
