Photosynthesis is the process in which plants make their own food using carbon dioxide, water and sunlight. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Sex-linked genes are those genes that found on sex-chromosomes (X and Y chromosomes) and their phenotypic expression for a trait depends on the gender of the offspring.
Most of the sex-linked genes are present on X chromosomes as X chromosomes have more number of genes as they are made up of more DNA as compared to Y chromosome.
However, male individuals are more likely to exhibit the sex-linked traits. It is because most of the sex-linked traits are recessive and males have only one copy of X chromosome, while females have two copies of X chromosome. One mutated copy in male can exhibit the trait, while in females, both of the mutated copies are required to exhibit that trait.
At many convergent boundaries a subduction zone is formed which drives crust down toward the mantle where the rock is melted and turned to igneous rock.
Explanation:
Where an oceanic crust meets a continental crust at a convergent boundary the oceanic crust is subducted under the continental crust. As the oceanic crust is driven down the friction, pressure and heat of the mantle melts the oceanic crust. The melted crust become igneous rock and often comes to surface in volcanos found near the convergent boundary.
The melted crust that doesn't reach the surface becomes igneous granite while the melted crust that does reach the surface becomes lava.
The question unanswered is how thick layers of oceanic crust ends up on the continents when what is observed today is the destruction of oceanic crust at subduction zones, due to convergent boundaries.
Different lengths of Poly A tails are present for different mRNAs so when we compare two peptides translated in two different cells we have different lengths of PolyA tail
PolyA tail is basically a long chain of nucleotides(adenine nucleotides) which are added to messenger RNA(mRNA) during processing of RNA
It increases the stability of the molecule
It protects the mRNA molecule from undergoing degradation in the cytoplasm
It is involved in binding proteins which further initiates translation;introns are removed from pre mRNA before the final mRNA is exported into cytoplasm
