Answer:
Limiting human use of nitrogen that is in the atmosphere.
Explanation:
Globin 1 and globin 2 genes of insects are understood to have diverged approximately 170 million years ago, through duplication, from a common globin gene ancestor. The two genes that code for haemoglobin have conserved regions; oxygen-binding and heme- regions. Globin 2 gene has lost the intron region that is still present in the globin 1 gene. The percentage divergence is 7.2% with 20 varying nucleotides.
The polarity of water enables it to serve as a solvent for polar substances.
A polar substance is a substance that has a positive end and a negative end. Water itself is a polar substance and this polarity enables it to dissolve polar substances.
For instance, HCl dissolves in water because it is polar. The positive end of the dipole in HCl attaches to the negative end of the dipole in water and the negative end of the dipole in HCl attaches to the positive end of the dipole in water.
This dipole - dipole interaction accounts for the dissolution of HCl in water.
Also, ion - dipole interaction accounts for the dissolution of ionic substances such as NaCl in water.

The two major systems involved in the stress response are the Nervous System [the Sympathetic subdivision of the Autonomic Nervous System (ANS)] and the Endocrine System (glands which secrete hormones intonthe bloodstream).
The Endocrine System's response during acute and/or chronic stress (adaptation) involves first the Hypothalamic release of Corticotropin-Releasing Hormone (CRH), which stimulates the Anterior Pituitary (via the blood) to release AdrenoCorticoTropic Hormone (ACTH), which then activates the Adrenal Cortex to release glucocorticoid hormones (i.e. Cortisol), amongst others into the bloodstream. Cortisol then has many effects on tissues and organs throughout the body to allow better generalized coping with the initial stress stimulus.
Nucleotides lining up along the template strand according to base pairing rules process helps to preserve the genetic information stored in DNA during DNA replication
Option D
<h3><u>Explanation:</u></h3>
The DNA is a semi conservative molecule from the genetic information storing point of view. The genetic information is stored there in form of the alignment and arrangement of the nitrogen bases. These nitrogen bases are replicated just in order to conserve the genetic information.
During protein synthesis, same nitrogen bases get denoted in the RNAs and this gives the particular protein which is required in the body. No molecule present in the body can destroy the DNA and its alignment. It’s conserved as long as no external molecule or force destroys it. So it’s conserved in a very safe way.
