Which phase best describes a chapparal

The options attached to this question are given below:

A. contains mostly needle-leaved evergreen trees.

B. is home to herds of giraffes, zebras, and wildebeests.

C. receives less than 25 cm of precipitation per year.

D. has low-growing; touch shrubs and rock, dry soils .

ANSWER

The correct option is D.

The chappral biome is one of the most widespread biome in the world, it can be found on almost all continents. The major characteristic of the biome include the following:

It has both forest and grassland,

It has two major seasons, winter and summer; the summer season is usually very dry and last for about five months.

The dry summer makes the biome sensitive to fire outbreak, which is a common occurrence there.

The amount of rain available to the biome is about 10 - 17 inches per year and is only able to support shrubs growth, only few trees can be found in the biome.

The biome can be a plain, a rolling hill or a mountain and the soil is usually very dry.  

transcription is a process in which information is rewritten. it is something our cells must do, in a more specialized and narrowly defined way. in biology, transcription is the process of copying out the dna sequence of a gene in the similar alphabet of rna. it needs to happen in the nucleus because that's where the dna is. dna is always inside the nucleus unless the cell is dividing.

transcription is the first step in gene expression, which involves copying a gene's dna sequence to make an rna molecule. transcription is performed by rna polymerases. it has three stages: initiation, elongation, and termination. rna molecules must be processed after transcription in eukaryotes.

explanation:

long version:

the protein synthesis consists two processes which are, transcription and translation. transcription takes place in the nucleus. it uses dna as a template to make an rna molecule. rna then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. transcription is the first part of the central dogma of molecular biology: dna → rna. it is the transfer of genetic instructions in dna to messenger rna (mrna). during transcription, a strand of mrna is made that is complementary to a strand of dna.  

these three stages are:

  initiation: in which   is the beginning of transcription.occuring when the enzyme rna polymerase binds to a region of a gene called the promoter. this signals the dna to unwind so the enzyme can ‘‘read’’ the bases in one of the dna strands. the enzyme is now ready to make a strand of mrna with a complementary sequence of bases.

    elongation: in which is the addition of nucleotides to the mrna strand. rna polymerase reads the unwound dna strand and builds the mrna molecule, using complementary base pairs. there is a brief time during this process when the newly formed rna is bound to the unwound dna. during this process, an adenine (a) in the dna binds to an uracil (u) in the rna.

    termination: in which is the ending of transcription, and occurs when rna polymerase crosses a stop (termination) sequence in the gene. the mrna strand is complete, and it detaches from dna.
