Hi!
Homologous chromosomes are found in any normal/basic diploid cell and a homologous pair of chromosomes will be identical genetic copies of each other.
Being that both of these answer choices appear to be correct, the answer would be letter choice (E) two of the above are true?
Hope I could help!

Answer - D
All of the options mentioned above stand true for the properties of the transfer RNA except for D. Transfer RNA has a 3 letter region known as "Anticodon" that matches with the "codon" of messenger RNA.
The Anticodon on transfer RNA is made up of 3 nucleotides, and the codon of the messenger RNA are 3 bases. These nucleotides and the bases correspond with each other.
Answer:
The method used by Atlantic cod to maintain homeostasis is discussed below.
Explanation:
Active transport is the movement of molecules from an area of lower concentration to an area of higher concentration against the concentration gradient.
The Atlantic cod would drink seawater to meet its water needs. But as this water will contain excess amounts of sodium and chlorine ions, the Atlantic cod will use the mechanism of active transport to move the sodium and chlorine atoms from its body. Due to active transport,the excess salt atoms will pass on again into the water. Unlike diffusion, energy is used for the process of active transport to occur.
The average square inch (6.5 cm2) of skin holds 650 sweat glands, 20 blood vessels, 60,000 melanocytes and more than 1000 nerve endings.
So it is TRUE
