Answer:
b. Because none of the precautions they took were effective, the pharaohs found a new burial ground in the Valley of the Kings.
Explanation:
According to the excerpt from "Egyptian Tombs: A Grave Matter,” the cause-effect relationship is illustrated in the fact that pharaohs understood their burial places were in danger of thieves, so they decided protect their tombs and treasures in the Valley of the Kings, whose location was much harder for thieves to break in.

Hi !!
The conclusion to Damian's argument is positive as he is aware of what the problem still is the second one ===>
-
EXPLANATION
<u>He cannot say</u><u> </u>:
1- it's absurd that we have this problem when there is such an easy solution, <em>because he wants things to change</em>
<u>He knows that </u>:
1- Unfortunately, more 100 million plastic grocery bags are still being thrown away every year.
2- Although attempts have been made to recycle these plastic bags, the problem cause by them still exists.
So it's conclusion is that we have to change ►
<u>We need</u> to take active steps and change <u>our habits</u> by using reusable bags instead.
hope this helps ☺☺☺
Answer:
Viruses are prone to clumping together. Many times extensive sequence changes may not make a difference in antibody recognition. While sometimes small changes in HA are sufficient for a large antigenic distance. That is, with few mutations, some Hemagglutinins may be much less recognized by the antibodies.
Explanation:
As the virus replicates in the body of infected people, the immune system captures several pieces of viral protein, the antigenic antibodies, and produces antibodies against them. There are other types of immune responses, too, but they do not cause long-term immunity, so that is beside the point. The two main viral targets of the antibodies are Hemagglutinin and Neuraminidase, since they are the most exposed proteins of the virus. When antibodies associate with them, in addition to signaling macrophages and other types of defense cells that that foreign body (the virus) has to be attacked, they can still prevent the virus from working. An antibody that attacks the Hemagglutinin receptor recognition region prevents it from associating with cells. They are the so-called neutralizing antibodies.
