1. What would likely happen if the wind hit the mountain? Will it change direction?
Answer:
Yup
Explanation:
The only other option would be that the wind does not change direction when it hit the mountain, which would mean that the wind goes straight through the mountain. While it is likely that on the atomic level this happens on a small scale, but for the most part, the wind would be forced to change direction due to the density of the mountain.

How can vaccines eventually eradicate an infectious disease?
Answer:
Two infectious diseases have successfully been eradicated: smallpox and rinderpest. There are also four ongoing programs, targeting poliomyelitis, yaws, dracunculiasis, and malaria.
Explanation:
Answer:
with some diseases such as small pox, if someone is able to survive against the disease they will be able to have a lifetime immunity from getting that said disease again. with vaccines, they inject a small amount of the disease into you, so that your cells that protect you from that disease will get accustomed to that said disease. with that being said, if there is an infectious disease once they get a vaccine going, if you start getting that vaccination for it at a young age, your body will become "immune" to it, so that when you have kids basically theyll have the genes that already have been introduced to it, so as more and more people stop getting that disease more and more people start becoming "immune" to it, causing it to die out and either become a very rare disease to get or wiped out completely

Segments of DNA, or genes, contain specific sequences that are transcribed as mRNA and translated to produce specific _____________.
Answer: i think the answer would be proteins, but please dont kill me if it isnt :( im in midle school so we recently covered this.
Explanation
heres the deal
dna- transcribed to rna example: AGT- UCA, then you trabslate it, which then turns into specific proteins after being coded by codons (3 nucleotides put together.) hope this helps!
think nucleotide= A or G or C or T
CODES: A codes for T
C 4 G
in RNA, Thymine (T) codes for Uracil (U)
