It is phototropism. Photosynthesis is the way plants make their food, from light. Notice the photo in both the words, meaning light.
<h2>Point mutation.</h2>
Explanation:
- The protein will be unchanged.
Mutation is defined as a change in nucleotide sequence of a gene. When a single nucleotide is inserted,deleted or substituted in a DNA sequence, then the resulting mutation is classified as point mutation.
A gene contains two region- intron region and exon region.
The region that codes for a particular protein is called the exon and the region that separates two exons and does not code for any protein is called the intron.
Most of the point mutations in the intron region are silent except if it is located at the splice site recognition sequence.
In the given situation the mutation is in the middle of the intron region so there is no chance of it being a splice site recognition sequence. Hence the protein will remain unchanged.
Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Answer: D- Dicer
Explanation:
Dicer, also known as endoribonuclease Dicer or helicase with RNase motif, is an enzyme that in humans is encoded by the DICER1 gene. Being part of the RNase III family, Dicer cleaves double-stranded RNA (dsRNA) and pre-microRNA (pre-miRNA) into short double-stranded RNA fragments called small interfering RNA and microRNA, respectively. These fragments are approximately 20-25 base pairs long with a two-base overhang on the 5' ends. Dicer facilitates the activation of the RNA-induced silencing complex (RISC), which is essential for RNA interference. RISC has a catalytic component Argonaute, which is an endonuclease capable of degrading messenger RNA (mRNA).
