Cells have unique characteristics wherein each develop a specific function determined by the activation of certain DNA sequences to generate this specific cell into its supposed design, this is why cell specialization exists.
Hence, these cells can be directly identified with their morphological structures and the DNA sequences they posses.

Answer:
Yes i<span>t is necessary for the testes to be kept below body temperature.
</span>
Explanation:
Testes contain sperm producing cells which require an optimum temperature of 35.5 C for sperm production. Out side testes body normal temperature is 37C. In order to produce sperm the temperature will below the body average temperatue. thats why in summer the testes hang below the body in scrotum, while in winter it is in close contact with body due to low temperature.
Answer:
<u>Genes</u> are the hereditary determinant of a trait or a section of DNA that codes for a protein.
Explanation:
Genes can be described as the basic unit of inheritance. Genes are made up of DNA. Genes determine the physical and genetic characteristics of an organism. Each gene carries a specific genetic code to code for a protein. However, there are many genes which do not code for any proteins and are termed as non- coding genes.
A chromosome comprises of many genes. The location of a gene on a chromosome is termed as its loci.
Answer:
Viruses do not belong in any kingdom, for they are unique organisms Viruses also lack organelles, cannot respire, and cannot conduct metabolic functions. Bacteria fall under a Domain, perform metabolic functions, and have DNA, just like viruses do.
Explanation:
Viruses & Bacteria have DNA, Viruses do not have organelles or ability to perform metabolic functions.
