Rough ER is studded with ribosomes and the Smooth ER has a smooth surface ..
Answer:
Population change is 15
Explanation:
To calculate the change in populations, we add up the immigrants and births and the subtract the deaths and emigrant from it
Change in pop = (birth + immigrants) - (death + emigrants).
Where birth is 25, immigrants is 5, death is 10 and emigrants is 5.
Change in pop = (25+5) - (10+5)
= 30-15
Change in population is 15.
The answer is D because <span>In </span>exocytosis<span>, materials are </span>exported<span> out of the cell via secretory vesicles. In this process, the Golgi complex packages macromolecules into transport vesicles that travel to and fuse with the plasma membrane. This fusion causes the vesicle to spill its contents out of the cell. Exocytosis is important in expulsion of waste materials out of the cell and in the secretion of cellular products such as digestive enzymes or hormones.</span>
Answer:
constitutive mutations
Explanation:
Constitutive mutations -
They are the strains which uninterruptedly make proteins , and therefore , can lead to excess of protiens and the process is very difficult or nearly impossible to stop , is known as the process of Constitutive mutations .
One of the example of this process of Constitutive mutations is ,
The strain with lac operon mutation which can even results in th etranscription of the lac genes .
Hence , from the statement of the question ,the correct term is Constitutive mutations .
<span>The Hardy – Weinberg principle has seven conditions that should occur in the evolution of the population. One is when mutation does not happen. Two, is when natural selection is not occurring. Three, if the population is infinitely large. Four, if all the members of the population produce offspring. Five, sexual intercourse is random. Six, the population will produce the same number of offspring. And lastly, the population does not migrate from one place into the other. Th thing that would disrupt the genetic equilibrium is the mutation.</span>
