The body can only synthesize 11 of the 20 amino acids, all other nine needs to be incorporate with food and those are the ones that we call essential amino acids.
Most of the metabolic cycles use carbon coming from glycolysis, the pentose phosphate pathway or the Krebs cycle.
Answer:
Convergent Evolution
Explanation:
Convergent evolution occurs when two unrelated species that have no common ancestor evolve independently in order to adapt to a similar environmental constraints to ensure survival.
An example of convergent evolution can be seen in birds, bats, flight/wing insects. They all do not share a common ancestor, but have evolved, separately, a similar structure for flight.
Another example can be seen in dolphins and sharks. These two different species share similar physical characteristics that make them adapt well in marine habitat that helps them to predate

Best Answer: Well, you have to look at the onion slide under the microscope and looks at each cell and tell what stage (interphase, prophase, etc.) they are in. and then for the description probably tell which one there is the most of and maybe why you think that is. You can find pictures of each phase in your book. I did a lab like this not too long ago in my bio class lol. And, i believe that you will get a lot in interphase (when cells are not currently dividing), just to let you know.
The answer is The ions are protected inside the lipid bilayer so that it is not pushed back to a more polar environment.
The lipid bilayer is mainly composed of lipids (phospholipids and cholesterol), and is also composed of proteins such as transporters.
The ions (which are polar) can not cross directly through the lipids because they will repel them due to their apolarity. On the other hand they can easily pass through protein channels that will protect them during their passage (the proteins are more polar than lipids).
Answer:
The correct answer is option C) phagocytosis in the inflammatory response.
Explanation:
Our body has an immune response mechanism for when we get hurt or when<u> it feels that something outside our body wants to harm us</u>, so its automatic reaction is to defend against all those bacteria and viruses that want to attack us.
The system is responsible for <u>identifying the antigens and destroying them.</u> The antigens are all bacteria, harmful viruses and dead substances that are found on the cells. Our system has its own proteins that are HLA antigens. But as these are normal for the body, it does not counterattack them.
There are <u>several defense mechanisms that work as barriers</u> to prohibit the passage of any bacteria that harm us, and one of these mechanisms is inflammation.
In this case, when our body suffers some kind of injury from a bacterium, a cut or a blow, the damaged cells release substances that spill onto the tissue through the blood vessels, causing inflammation.
This allows the foreign substance to be “locked up” and cannot enter the body.
These spilled substances also attract white blood cells, which are called phagocytes which<u> are responsible for eating dead germs and cells</u> through the phagocytosis process.
