This is the pepsin primary sequence of the amino acid residues within the protein (1pso):




glapva
- describe details of the primary sequence (eg number of amino acid residues).
- label and describe carboxy and amino termini.
- label extra features besides the ends, two other regions of the protein and describe their function using simple language.
- describe catalytic sequences or other important amino acid residues.
- describe a feature of amino acid chemistry (eg. signal peptide, which is composed of hydrophobic amino acids or chemistry of an important amino acid residue).

c. heat could easily travel through the molecules in the air and escape/enter the flask. removing the air slows down the heat transfer.  

explanation:

venn diagram is pictorial representation with of circles showing the relation between two finite sets or things. the intersection part of two circles conveys the relation present in between those sets or things.

here in the venn diagram of sand and salt two circles represent sand and salt. but the area falling under the intersection of these circle represents the mixture of sand and salt.

so, in a venn diagram the mixture will be placed in a middle that is in between the intersection of two circles.

the answer is a for sure mark brainliest i had got this right on usatestprep
