Misha Larkins [42]

Answer:

Secondary succession

Explanation:

When a previously occupied area is re-colonized after a natural disaster or human  activities that wiped out the previous community, then the type of succession is called a secondary succession.   A practical example is abandoned farmland that a farmer left for a period of time and later revisited  for farming afterwards.

Because the pioneer organism( sun-loving plants )  were already on ground it will be fast  for them to populate the area,grasses will   sprout up  too. insects, dentritivores, reptiles will move into the habitats.

After 5years;The habitat is populated by  shrubs, which owns the forest floors.  small pine, oak may soon join.a  stable climax community.

Assuming the community is not interfere with  bigger  dominant trees , e,g the oak developed  and other tree  developed to bigger tree , followed by more  insects, birds, rodents, herbivores and some carnivores, This entire sequence of event may take 50 years, to reach this climax community.

A very rare disease will cause damage to the ribosomes in cells. what would be the direct effect of this disease?
DochEvi [55]

Answer:

A rare disease that causes damage to the cell's ribosomes will have as a direct effect the inability to perform protein synthesis.

Explanation:

Ribosomes are cellular organelles formed by proteins and a type of RNA called ribosomal RNA, whose function is to translate the genetic code of the mRNA codon sequence and convert it into amino acids. This implies the first step for protein synthesis to occur.

<em><u>If a rare disease could structurally or functionally affect the ribosomes, the translation of mRNA into amino acids could not occur, so protein synthesis in the cell would not be possible</u></em>.

The consequences of the lack of protein synthesis involve severe consequences on the structure and function of a living organism.
