Igneous, Metamorphic, and Sedimentary are the three main classes of rocks.
Population growth is the increase in the population number of a given species in a time. Longevity, migration and fertility rates affect population growth.
<h3>What are the factors affecting population growth?</h3>
<u>Increased Longevity</u> has impacted the population growth as the life expectancy has resulted in the accumulation of more people as their age of living has increased.
<u>International Migration</u> can affect the population growth positively and negatively as moving of the person from one region will decrease its population growth while the region where they go will have increased population.
<u>Fertility Rates</u> has a great impact on the population as the fertility rate had decreased due to many factors and the population has declined.
Therefore, option A. longevity option B. migration and option C. fertility rates influence the population growth.

<span>Let's consider a scenario in which the resting membrane potential changes from −70 mV to +70 mV, but the concentrations of all ions in the intracellular and extracellular fluids are unchanged. Predict how this change in membrane potential affects the movement of Na+. The electrical gradient for Na+ would tend to move Na+ Outside the cell (extracellular) while the chemical gradient for Na+ would tend to move Na+ Inside the cell (intracellular).
The electrical gradient is defined as the + goes to the - and the - goes to the +
Na + has a positive charge, but there's more positive charge inside the cell than outside (due to potassium), therefore, Na+ goes extracellular (out)
The concentration gradient considers that the ion will go from the most concentrated to at least concentrated by passive diffusion so no trans-membrane proteins in the game attention.Na + is very concentrated in extracellular and few intracellular, therefore, it tends to go intracellular (in).</span>
When influenza occurs in unusually large in numbers over the specific area it is called a/an epidemic
An epidemic in influenza is most different from that dreaded of pandemic that scientists and the world health officials fear is the nigh. We might see an epidemic of the seasonal influenza and during any given year. In fact, we just had that one.
Flu reached the epidemic levels in the U.S. and for the 10 weeks in a row during the 2004-2005 seasons 5, 8.9% of all the deaths reported in the 122 U.S. cities were due to the influenza and the pneumonia (a common complication of the flu).

Urm,Is that a question or what,I'm confused.
