Correct Answer: Casein
Correct Answer: Iodine
Correct Answer: Pulmonary arteries
Correct Answer: hormone
Correct Answer: AB+
Correct Answer: Ribonucleic Acid
Correct Answer: a nitrogenous base, deoxyribose sugar and phosphate group
Explanation:
The two DNA strands are called polynucleotidesbecause they are composed of simpler monomer units called nucleotides. Eachnucleotideis composed of one of four nitrogen-containingnucleobases (cytosine, guanine, adenine or thymine), a sugar called deoxyribose, and a phosphate group.
Correct Answer: single-stranded RNA
Explanation:
Generally viruses that infect plants have single stranded RNA. Viruses infecting animals have double stranded RNA or DNA. Viruses which infect bacteria have double stranded DNA.
Correct Answer: diploid zygote
Explanation:
Syngamy, also known as fertilisation occurs between the male and female gametes. Syngamy may occur either externally, outside the body of organisms or internally, inside the body. Syngamy leads to formation of a specialised cell called diploid zygote.
Correct Answer: Vitamin C
