Mendel’s model of inheritance involves the passing of individually separate units of inheritance, or genetics, from parents to babies.
Asexual reproduction generates offspring that are genetically identical to a single parent. In sexual reproduction, two parents contribute genetic information to produce unique offspring. Sexual and asexual reproduction have advantages and disadvantages—which is why some organisms do both!
Answer:
The function of the pleura is to allow optimal expansion and contraction of the lungs during breathing. The pleural fluid acts as a lubricant, allowing the parietal and visceral pleura to glide over each other friction free. This fluid is produced by the pleural layers themselves.
Answer:
The correct answer will be option-A
Explanation:
The process of transcription form a transcript molecule called mRNA from a single strand of DNA called template strand or antisense strand.
The process of transcription is mediated by the RNA polymerase enzyme which adds the nucleotide base pairs in (A, U, G, or C) to 3' end of the strand thus synthesizing the strand in 5'–3' direction.
Since the direction of adding the nucleotide is to the 3' end, therefore the polarity of the template strand will be 3'–5' direction.
Thus, option-A is the correct answer.
