Answer:
C Differences among temperature, air pressure, and density
Explanation:
Classification of the atmosphere layer will be different based on the temperature, air pressure, and density. Generally, air pressure and density will go less at the higher layer, but the temperature varies greatly. Altitude and latitude define a location on earth, not the layer of atmosphere. Most weather just happens at the troposphere layer. The distance from ground level can be used as a rough estimate but not as precise criteria.
Anticodons are a part of transfer RNA(tRNA) molecules, and corresponds to a codon on a messenger RNA(mRNA) molecule.
Your answer is A, anticodon; codon.
A single stranded DNA (oligonucleotides) can hybridize with (d) both complementary DNA and complementary RNA.
DNA is the Deoxyribonucleic Acid. It is the genetic material present in majority of organisms. The nitrogenous bases present in DNA are: Adenine, thymine, Guanine and Cytosine. DNA is a double stranded structure hence it forms hydrogen bonds with a complementary strand. The complementary strand can be of a DNA or RNA.
RNA is the Ribonucleic Acid. It also is a genetic material present in very few organisms. RNA is less stable than the DNA and may be either single stranded or double stranded. The nitrogenous bases of RNA are: Adenine Uracil, Guanine and Cytosine.

Answer:
The correct answer is the alarm reaction.
Explanation:
The alarm reaction or stage is the initial stage of the body's response to a stressful situation or stimuli, due to acquired physiological changes, such as high heart rate and increase in hormones activity.
In simple words, it is a reaction that body adapts in tough or fight or flight situation by pumping blood from the heart to arms and legs to fight or flight.
Thus, the correct answer is alarm reaction.
