Spider silk is a material made of proteins that has a strength per gram that is five times that of steel. One feature of some of the toughest spider silks is a high proportion of β sheets that stack tightly together to form crystal-like arrays. Which amino acids would you expect to be common in such crystalline stacks and why?

Answers

Answer 1

Answer:

glutamic acid, because the R group could form ionic bonds

arginine, because the R group could form ionic bonds

tryptophan and tyrosine, because the R groups are small, allowing close stacking

glycine and alanine, because the R groups are small, allowing close stacking

Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.
Neptune is an inner planet with a thicker atmosphere and a shorter year than Mercury.
Neptune is an outer planet with a thinner atmosphere and a shorter year than Mercury.

Answers

Answer:

B because Mercury's orbit is 88 days and Neptune's is 164 earth years

Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.

What is Mercury and Neptune?

Since 2011, Neptune has spent 12 years in the sign of Pisces, which it rules and enjoys being in. Mercury spends just 15 to 60 days in each sign of the zodiac, but because of the Mercury retrograde, they come together and hang out for a while.

This is incredibly uncommon. It may be said that Mercury, the hare, is enjoying a Long sleep with Neptune in a dreamy fog and has forgotten his responsibilities as a courier around the Earth.

When Mercury conjoined the Sun on March 14 at 24 degrees Pisces and then today, on March 25, when Mercury conjoined Neptune at 16 degrees Pisces, this was notably felt.

Therefore, Mercury is an inner planet with a thinner atmosphere and a shorter year than Neptune.
