Answer:
true
Explanation:
abiotic means nonliving and biotic means living
Carbohydrates. The digestion of carbohydrates begins in the mouth. The salivary enzyme amylase begins the breakdown of food starches into maltose, a disaccharide. As the food travels through the esophagus to the stomach, no significant digestion of carbohydrates takes place.
Answer:
CnH2n+2
Explanation:
an alkane consists of hydrogen and carbon atoms arranged in a tree structure in which all the carbon–carbon bonds are single.
First of all there nothing exists something like SSA congruence criterion, It is SAS Congruence where the sides of a Triangle and the angle between them is exactly same to the other two sides and angle between them of another triangle.
So the correct option is D.
Explanation:
If the Triangle has two sides equal, so the two angles there are equal. Also the other angle be some other definite angle. So
45+x+x=180(Considering definite angle to be 45)
2x=135
x=67.5
So there is only one solution to the triangle.
Answer:
Cystein, threonine and tryptophan can form hydrogen bond with progesterone
Explanation:
Those amino acids have -OH or H subunit in their side chain and these moities are very esential for hydrogen bond formstion with progesterone
A hydrogen bond can be said to be a partial intermolecular bonding between a lone pair on an electron rich donor atom, particularly highly electronegatine elements like nitrogen, oxygen, or fluorine and the antibonding orbital of a bond between hydrogen (H) and another more electronegative atom or group. Dotted or dashed line is always used to indicates the hydrogen bond.
Hydrogen bonding can also be seen existing between water molecules or hydrogen fluoride molecules since each molecule contains hydrogen bonded to a hyghly electronegative element.
