There are multiple different forest types on the planet, all of them with their own unique characteristics creating a certain forest ecosystem.
The tropical forests are evergreen, so are the boreal forests, but the temperate forests shade their leaves each autumn and grow them again in the spring. The tropical forests are fully active all year around, the boreal despite being green all the time are not active for big portion of the year, while the temperate forests are active from the end of the winter until mid autumn. The tropical forests create a lot of material for decomposition thus making the top part of the soil very fertile, the boreal forests do not create a lot of material for decomposition but instead very little which makes the soil relatively poor, and the temperate forests create a lot of material for decomposition especially in the autumn when they shed their leaves, thus contributing to very fertile top layer of the soil. The tropical forests have enormous biodiversity, the boreal forests are very monotonous and have very little biodiversity, while the temperate forests are kind of in between with medium level of biodiversity.
The correct answer is: b. the removal of introns and alternative splicing of exons
Post-transcriptional regulation includes processes of regulation between transcription and translation such as RNA splicing, capping, addition of poly-A tail, RNA editing.
RNA splicing represents the process of RNA processing in which newly synthesized pre-mRNA transcript is converted into a mature mRNA. This process occurs only in eukaryotic organism and includes the removal of introns and joining together the exons. RNA splicing might occur during or immediately after transcription and it is performed by spliceosome (complex of small nuclear ribonucleo proteins).
Alternative splicing is a regulated process in which a single gene can code for multiple proteins because particular exons of a gene may be included within or excluded from the final mRNA.
The patients skin laceration healed nicely leaving a cicatrix, which is a scar.
A cicatrix is the scar of a healed wound - when you have a deep wound, and it gets stitched/heals on its own, after a while, that wound is going to transform into a cicatrix, which is just a fancy medical term for a scar.
Answer:
Rocks are in dry climate
Explanation:
Several types of rock , like granite, are very repellent to weathering. Moreover, igneous rocks serve to heat slowly because it is difficult for water to penetrate into them.
