Answer:
Explanation:
1. charge in trypsin
: two other molecules in elastase
2. Chymotrypsin cleaves peptide bonds after bulky or aromatic side chains, such as those of the amino acids phenylalanine or tyrosine. The specificity pocket, or substrate-binding site, is deep and has hydrophobic side chains.
Trypsin cleaves peptide bonds following basic amino acid side chains. Lysine and arginine both have basic amino acid side chains that are positively charged at pH 7. Trypsin's substrate-binding site contains a negatively charged amino acid residue.
Elastase cleaves peptide bonds after amino acids with small side chains, such as glycine, alanine, or valine. The specificity pocket for elastase has bulky side chains that block larger amino acid side chains, but can accomodate smaller side chains, such as the -H, -CH3, and -CH(CH3)2 side chains of glycine, alanine, and valine, respectively.
3. Their binding pockets
- trypsin = long & (-) D on bottom
- chymotrypsin = deep & wide
- elastase = aliphatic a.a. = shallow
Two species of finches found on the same galápagos island but feeding on different food sources is an example of sympatric speciation.
<h3>What is speciation?</h3>
Speciation is the evolutionary process that leads to reproductive isolation and eventually to the emergence of new species.
Sympatric speciation refers to the emergence of reproductive barriers in individuals of the same species that inhabit the same region, whereas allopatric speciation occurs in individuals separated by geographic barriers.
In conclusion, two species of finches found on the same galápagos island but feeding on different food sources is an example of sympatric speciation.

Ƒ An atom that gains one or more electronswill have a NEGATIVE charge. ƒ An atom that loses one or more electrons will have a POSTIVE charge. ƒ An atom that gains or losesone or more electrons is called an ION. ƒ A positive ion is called a CATION and a negative ion is called an ANION.
From this information above you can see its negative so it means it gets reduced
hope it helped
In this reaction the lead atoms gain anelectron (reduction) while the oxygen loses electrons (oxidation). Magnesium loses electrons and is therefore said to be "oxidized", whereas the chlorines gain electrons and are said to be reduced
and as you can see oxidation only happens when oxygen is reduced
Hey there!
The answer would be ultrasound.
The ultrasound is considered safe because it uses sound waves for the detection of tissue, organ, baby etc. These waves are considered safe and transfer only a small amount of heat to the tissue in which the ultrasound is done. A little amount of heat is not at all harmful to the body in any means. Early defects of baby can be detected through this procedure, the merits of the process is much higher than its demerits.
Hope this helps !
