Like you might have studied. Heated hair expands while colder air contracts. So, the sound isn't able to move as efficiently in cold air than it would in warmer air.
<u>Answer:</u>
CCGAGU
<u>Explanation:</u>
DNA transcription:
DNA transcription is the process through which DNA double helical strand is converted into single stranded RNA molecule.
During transcription two strands of DNA are named differently i.e Template strand and coding strand.
Template strand:
Strand from which RNA is producing is known as template strand while
Coding strand:
The strand which is opposite to the template strand is known as the coding strand. Coding strand is the DNA strand whose nucleotide sequence resembles to the RNA transcript base sequence except thymine which is replaced by uracil.
Correct Answer:
Template strand from 5' to 3' reads GGCTCA. and
In this question CCGAGT is coding strand.
RNA sequence is same as coding sequence except T which is replaced by U so sequence of RNA becomes
CCGAGU
Answer:
What are so called breast-cancer genes, are mutations in two genes: BRCA1 (BReast CAncer gene one) and BRCA2 (BReast CAncer gene two), and are also associated with ovaric cancer. According to the question, these genes are present in the popolation despite surgeries and deaths, and asks why. Surgeries does not eliminate the genes, they eliminate the tumors, and people can still reproduce after that. And also, most people already had offspring before they know they have cancer, so they are inheriting the mutations on the genes anyway.
Explanation:
The central nervous system (CNS), which is made up of the brain and the spinal cord, and the peripheral nervous system (PNS), which is comprised of nerves and ganglia (small concentrations of grey matter).
The brain sends messages to the peripheral nerves in the body via the spinal cord, these have control of muscles and internal organs.
