The mouse gene consists of 1800 nucleotides. 600 of them are introns *. This fragment of the gene The coding part - the exon - contains 300 adenyl, 200 thymidyl, 100 guanyl nucleotides. Cytosine Determine the number of nucleotides, the percentage of nucleotides in DNA. Exon of DNA How many amino acids are in the protein synthesized from * (We do not count introns when calculating the number of amino acids, because introns non-coding regions, which are removed from the mRNA and do not participate in protein biosynthesis)

thrombocytopenia, which is a deficiency in blood platelets, can cause bleeding and bruising in the dermis similar to senile purpura. other possible causes include: exposure to ultraviolet rays and aging skin are common causes of senile purpura. senile purpura may also be a sign of collagen loss in the skin and bones.

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.

sodium i think the chemical element of atomic number 11, a soft silver-white reactive metal of the alkali metal group.

answer;

c. a tree whose roots are surrounded by wet sand.

explanation;

water stress is an important factor limiting the growth and productivity of forests.water stress is the most often cited cause of poor survival and growth of woody landscape plants.

-insufficient soil moisture is the most common form of water stress, but excess moisture that leads to poor soil aeration (hypoxia) can also result in reduced plant vitality. a tree whose roots are surrounded by wet sand would be least likely to experience water stress.
