The ways in which an element—or compound such as water—moves between its various living and nonliving forms and locations in the biosphere is called a biogeochemical cycle. Biogeochemical cycles important to living organisms include the water, carbon, nitrogen, phosphorus, and sulfur cycles.
I believe that her behavior provides an example of Hypochondriasis.
Hypochondriasis is a condition in which a person is inordinately worried about having a serious illness. It is often characterized by fears that minor bodily or mental symptoms may indicate a serious illness, constant self-examination and self-diagnosis, and a preoccupation with one's body.
Answer:
This question is incomplete as it lacks options; the options are:
A) Bond X only
B) Bond W only
C) Bonds Y and Z at the same time
D) Bonds W and Z at the same time
The answer is C. Bond Y and Z at the same time
Explanation:
A DNA molecule is a double-stranded molecule made up of nucleotide units. According to this question, radiation can damage the nucleotides in the DNA molecule. However, the cell can repair this DNA molecule by removing the single damaged nucleotide and replacing it with an undamaged one.
In this case, the cytosine nucleotide is the damaged nucleotide. To repair this DNA in the image, the covalent bond holding the one nucleotide to another in one of the DNA strands must be broken.
The sugar-phosphate bonds as represented by letters Y and Z are the bonds that could be broken to replace the cytosine nucleotide by an undamaged one, without affecting the biological information coded to the DNA molecule. The bonds holding the neighboring nucleotides are also broken during the repair process. Note that, this form of repair is called BASE EXCISION REPAIR
The answer is A. Nucleus-forms peptide bonds
B. Mitochondria
The process of cellular respiration is essentially when oxygen and carbon transfuse themselves together to create carb on dioxide, which in turns creates energy.
The entire process is formed in the powerhouse of the cell, or in other words, the mitochondria.
A part of this question that may have been confusing is the answer, "lungs". Since respiration is correlated to the lungs, you may have been confused. However, this is a process that occurs within your cells, so on a small scale than your entire body.
