Answer:
There are many things that can be read from ripple marks in sedimentary rocks. To start, a geologist looks at: the types (sizes, composition, shapes) of grains in the rock, the height of the “waves”, the distance between peaks (highs) and troughs (lows), whether the rock seems to be lying in its original position, and the internal shapes of the ripples (by looking at the edges of broken pieces). They also seek to determine the age of the rock and information about other rocks lying below and above the specific rock.
The first one i think it is the first one
Answer:
The guanidine group of the first two arginine forms a pair of ions, by which salt bridge is formed
Glycine In both sequence, act as non-polar amino acid and two leucine of enzymes will form a hydrophobic groove. isoleucine fits into the hydrophobic groove.
In R-R-G-S-I serine is phosphorylated by an active catalytic subunit .
In R-R-G-A-I serine is been replaced by alanine
Explanation:
The role of the each amino acids

Answer:
Animals capable of feeding at many trophic levels will be able to survive if portions of their food supply are decreased or eliminate is not true of about trophic levels
Explanation:
This is because each trophic levels represent energy flow and supply of food to the organisms in the trophic levels. Energy are pass from one tropic levels to another as a result of source of food there. Plants majorly are the primary producers and the primary consumers depend on it. Therefore, if the source of food supply is eliminated in a trophic level, the organisms I'm the trophic level will not be able to survive.
