Is the importance of an element in the body related to its percentage of body weight?
Brilliant_brown [7]
<h2>Answer with Explanation </h2>

The elements that are required for the human body are in fixed percentages Whatever the weight of a person the percentage remains the same. Like 70-90% water is present in the human body whatever the weight of a person but the percentage of water remains the same in the body. There are six main elements present in the body which are basic and necessary for the human body are oxygen, nitrogen, carbon, phosphorus, calcium, and hydrogen.

Which is not a basic function of cell?
andre [41]
Cells are always known to be the building blocks of life or the basic unit of life. It constitutes cytoplasm inside a membrane with which comprise biomolecules like nucleic acids and proteins. A cell has 3 major functions. One of these functions is to transport molecules. Since cell membrane acts as barriers to molecules, it should transport the molecules it needs. This transport can either be passive or active. Another cell function is to reproduce. Cell hast to reproduce to replace those that die. The last function is to convert energy. Through cellular respiration, cells produce energy.  The absolute source of energy of all living organisms is the adenosine triphosphate or ATP.

In a recent experiment, anti-bacterial hand sanitizer was compared to hand soap. Students washed their hands using the sanitizer
kramer

Answer:

B) The conclusion is not valid; there were fewer bacteria cultures on the soap plates

Explanation:

In a recent experiment, anti-bacterial hand sanitizer was compared to hand soap. Students washed their hands using the sanitizer or soap and warm water for two minutes; then they dried their hands with a paper towel. The standard of comparison was rubbing hands vigorously for 2 minutes in warm water, without any soap or sanitizer, and then drying with a paper towel. The sanitizer advertisement claimed to kill bacteria more effectively than any soap. After washing, hands were swabbed and then the swab applied to a culture plate and incubated. Finally, the bacterial cultures were counted and recorded in the data table. Students concluded that the hand sanitizer was most effective in killing bacteria. How would you respond to the students' conclusion?

                 Hand Washing Test Hand Washing Test

Treatment                                 Bacterial cultures (#/plate)

Warm water                                           24

Hand sanitizer                                       28

Soap A                                                    12

Soap B                                                    13

The above table should have been included before the question. From the table we can conclude that

B) The conclusion is not valid; there were fewer bacteria cultures on the soap plates

Which also means that the sanitizer is not as effective as warm water. it is the least effective solution to kill bacterial.

4. Describe how a selectively permeable membrane is involved in osmosis. Include the role that the solute concentration plays in
Taya2010 [7]

Answer:

All cells of living organisms depend on a protective barrier, called a membrane, that will ensure that the contents in and out of the cell are appropriately separated and balanced. In animal cells, especially, the cell´s plasma membrane works as a semi-permeable barrier that divides two environments that are equally submerged in water: the extracellular, and the intracellular environments. But it does not only divide water from both compartments; it also maintains a regulatory role in solute concentration, given that the laws of physics do not change, and water will always follow after solutes, and will go to where there is less concentration of water molecules.  

Osmosis, is one of the many ways in which cells are able to maintain the proper balance of both water, and solutes, in the extracellular and intracellular spaces, and plasma membranes (and plant cell walls) play a major role here. Essentially, these membranes are made of a center of lipids (completely hydrophobic), and two layers of phospholipid heads, that interact with water. These molecules are not rigidly and tightly packed together, but are somewhat fluid and permeable. It also contains a series of proteins that form sorts of transport chains and gates, that will ensure that water, solutes and molecules can appropriately cross in and out of the cell.

Water usually moves by osmosis in both plant cells and animal cells, thanks to the membrane´s permeability (in plants the cell wall) to it. Water, will thus move from one side to the other given two factors: concentration of water, and concentration of solutes; with water always following towards places with higher concentration of solutes, and lower concentration of water molecules. This balance of water and solutes on both spaces is vital to ensure that water does not leak in great amounts on either end, either bursting the cell, or dehydrating it to the point of death. And this is what the characteristic of semipermeability does; it allows water to diffuse through osmosis, but under certain conditions, which are kept under regulation by the membrane through other mechanisms like facilitated transport, and active transport, of solutes and molecules.

However, osmosis does not apply to solutes; these depend on the different proteins, channels, and carriers, that are present on membranes to be able to pass. Although, it is important to mention that cells keep their balance by having certain levels of leakage, especially for K+, in order to maintain stability, the norm is that in order for these to pass in and out of cells, they must count with cell membranes.

It is finally, because of membranes that the normal laws of physics regarding water concentration and solute concentrations, do not apply exactly as they should. These barriers ensure that a cell may live by keeping the strict balance to ensure survival.
