Answer:
B) Na+
Explanation: Na+ molecule is polar, oxygen and carbon dioxide are nonpolar molecules. The cell membrane is a <em>phospholipid bilayer</em> made up of lipid molecules with polar and nonpolar ends. Since it is a bilayer, two phospholipid layers are arranged, one on the other in such a way that one faces the back of the other. The non polar ends are away from outside and inside of the cell, while the polar ends faces towards all the molecules inside and outside the cell.
Since polar-polar molecules repel each other, Na+ can't pass through the cell membrane easily. So it uses the proteins attached the cell membrane inside and outside to transport such molecules by using energy in terms of ATP.
Warmth, moisture, pH levels and oxygen levels are the four big physical and chemical factors influencing microbial growth. In most buildings, warmth and moisture are the most significant overall issues current
<h3>How the bacterial growth curve relates to what happens to the bacterial population?</h3>
The bacterial growth curve symbolizes the number of live cells in a bacterial population over a period of time. There are four different phases of the growth curve: lag, exponential (log), stationary, and death. The initial phase is the lag phase where bacteria are metabolically functional but not dividing.
<h3>What are 4 states of bacterial growth?</h3>
Bacteria can live in more burning and colder temperatures than humans, but they do best in a warm, moist, protein-rich atmosphere that is pH neutral or slightly acidic. There are exceptions, however. Some bacteria flourish in extreme heat or cold, while others can stay under highly acidic or extremely salty conditions.

A food chain follows one path of energy and materials between species. A food web is more complex and is a whole system of connected food chains. In a food web, organisms are placed into different trophic levels. ... Producers are the basic trophic level while top predators are the peak level.
Well, humans have talents. Whether those talents are god given is up for debate. I'd argue those talents are a result of millions of years of evolution and natural selection as proven by Charles Darwin, not given by an unproven deity, but I don't know what school year you are in so you may not have escaped the years where religion is forced upon you :P
Anyway, if you're being asked this question, what do <em>you </em>like doing? I'd say my talent lies in science, as I was the top performing physicist throughout my gcse years, and I love the subject. In my opinion what you do best is what you love doing most, as if you have a passion for something it will almost always be your best talent. I can't answer that question for you.
Sharing this talent to others is basically teaching and also spreading your passion for your talent to others. They probably won't ever be as good as you because they will have their own talents and passions, but you can give them an insight into it by teaching them what you know and encouraging them to invest some time into it.
