Answer:B.
It was used to prove that smoking causes health problems.
Explanation:
Hairpin like structures are formed in both DNA and RNA but are common in RNA than in DNA. This is because DNA can be double stranded or single stranded while RNA is generally single stranded structure that can be double stranded only when it forms a hair pin like structure.
The features of hairpin structure in RNA are as follows:
1. This structure is a building block of many secondary structures of RNA.
2. The termination sequence during transcription also forms a hairpin loop like structure.
3. tRNA also forms a hairpin loop like structure and helps in the process of translation.
Answer:
<em>The probability of forming a "Y" gamete is 50%. The probability of forming a "y" gamete is 50%.</em>
Explanation:
Mendel was an Austrian monk whose findings led to make the foundation of genetics. Hence, Mendel is known as the father of genetics. He formulated two laws based on the researches he made:
- Law of segregation
- Law of independent assortment
According to the law of segregation, alleles segregate independently at the time of gamete formation. There is an equal chance for a gamete to carry the dominant or the recessive allele.
Hence, the probability of a gamete carrying a 'Y' or a 'y" allele will be 50% each.
Answer:
Gas (Chemical Energy)
Explanation:
Cars run on gas. They convert the chemical energy in the gas to motion. This is where the system gets its energy. (Unless your system is the car and it moves beacuse is on a hill in which case gravitational potential energy transfers energy to this system).
