Abrasion generally occurs four ways. Glaciation slowly grinds rocks picked up by ice against rock surfaces. Solid objects transported in river channels make abrasive surface contact with the bed and walls. Objects transported in waves breaking on coastlines cause abrasion. I HOPE THIS HELPED:)
The possible answers are:
A. Variation in length of the amino acid backbone
B. Each protein is encoded by a distinct gene
C. Variations in the type of peptide bond
D. Variations in the glycosidic linkage
E. Variation in tertiary structure
<span>F. Variations in which amino acids are used
The correct answers are A,E and F
There are only 20 amino acids that make all of the proteins in our bodies. However, there are options for protein variation are almost unlimited.
Firstly, you can vary the number of different amino acid that you use to make a protein.
Secondly, you can also vary the length of the amino acid chain.
And thirdly, when an amino acid chain is formed different parts of the chain interact with each other, bonding chemically, forming different 3-dimensional structures of the protein.
All of this contributes to the vast variation in proteins.</span>
Answer:
health, stressful life transitions, & care-giving responsibilities.
Explanation:
According to my research on senior citizen problems, I can say that based on the information provided within the question older adults typically worry more about matters such as health, stressful life transitions, & care-giving responsibilities. This is because at that age these are primary concerns that need solutions in order to live a good life.
I hope this answered your question. If you have any more questions feel free to ask away at Brainly.
Answer:
Xylem
Explanation:
Water moves from the roots to the leaves through tissue called the xylem, in a process called transpiration. As water evaporates out of the leaf, more water is 'pulled upwards' to replace what has been lost.
Because the molecules that are being transported is moving against its concentration. gradient. in other words, its moving from where it's low in concentration to where it's high in concentration.
