Non-protein coding DNA in eukaryotes contains repetitive elements that include (select all that apply): Group of answer choices
Olegator [25]

Answer:

interspersed, transposon-derived repeats, simple sequence repeats.

Explanation:

In the human genome, not only the protein coding genes are present, in fact these genes make up just a very little portion of the human genome about 1.5-2% of the entire human genome. Repeats make up about 48% of the human genome which is the largest and the rest include, conserved non coding sequences (43.5%), heterochromatin regions etc.  

Some of the repetitive elements includes LINEs, SINEs, DNA fossils tranposoon, Retrovirus like elements. all these are transposable elements which are  mobile DNA sequences that can migrate to different  regions/areas of the genome.

Microsatellites (simple sequence repeats) are tracts of repetitive DNA in which certain DNA motifs are repeated normally 5-50 times.

Which human body systems are involved in thermoregulation
ValentinkaMS [17]

Answer: The nervous system of human body is responsible for thermoregulation.

Explanation:

Thermoregulation is the process whereby an organism maintain its internal temperature despite changes in External temperature. The nervous system of human body is responsible for thermo regulation. The nervous system consist of nerves cells and fibres which send nerves impulses to the body parts. It comprises of central nervous system and peripheral nervous system. The centsl nervous system consist of brain and spinal cord while the peripheral nervous system consist of nerves. A part of the brain (central nervous system)called hypothalamus controls thermo regulation. When it senses a change in internal temperature of the body, its send signals to the organs, muscles, glands and nervous system , they respond differently so as to restore the body temperature to its normal one.
