A sand dune is the correct answer
Answer:
The correct answer is a. Exon/intron boundaries are typically characterized by a 5' GU splice junction and a 3' AG splice junction.
Explanation:
Splicing is the process in which the non-coding introns are removed from the mRNA and only coding sequences remains in mRNA.
The splicing of introns depends on the recognition of splice site pair. Usually, 5'-GU-3' is 5' splice site and 5'-AG-3' is 3' splice site which makes the boundary of introns/exons and these two nucleotides are important to recognize the introns.
There are some additional conserved sequence at these two splice site which help in recognition of introns. First, a lariate structure is formed when 5'-GU-3' is cleaved and joined to the branch point that is present near 3' slice site. Then 3' splice site is cleaved which releases the intron. Therefore the correct answer is a.
The key difference between microspore and pollen grain is that microspore is the small spore that develops into the male gametophyte in plants while pollen grain is the small grain that contains the male gametophyte.
Answer:
Water and Oxygen should be swapped.
Explanation:
The correct order should be:
Oxygen + Glucose --- becomes --- Carbon Dioxide + Water + Energy
Oxygen and Glucose react to become Carbon Dioxide and Water, providing energy in the process.
The chemical equation is:
C6H12O6 + 6O2 = 6CO2 + 6H2O + Energy
For each molecule of Glucose, C6H12O6, it takes 6 Oxygen atoms, or three pairs, to combine with the Glucose. The results are 6 molecules of CO2 and 6 molecules of H2O. The result is that energy is released, transferred.
