Lyell's theory that geological processes occurred over time led Darwin to formulate the concept "<span>if earth formations can change over time it is possible that even life on earth could change over millions of years." The correct option among all the options that are given in the question is the third option or option "c". </span>
The right option is; d. 366 people/mi^2
Population density is a measure of the number of people that constitute the population in a particular area per square kilometer or square mile.
From the question, the population of China is; 1,355,935,022, and the land area is; 3,705,405 mi^2.
Population Density = Number of People / Land Area.
Population Density =1,355,935,022/ 3,705,405 = 365.93 = 366 people/mi^2.
Therefore, the population density of China is 366 people per square mile.
Reproductive isolating mechanisms are barriers which impeded mating (prezygotic) or prevent the hybrid from developing properly (postzygotic) but the overall effect is to cause speciation by making it difficult for two diverging species to share genes. So one kind of mechanical isolation could be the usage of contraceptives. As of temporal isolation, or behavioral isolation could be exemplified by people who suffer from diseases that cause separation (such as HIV or cancer). I hope that this is the answer that you were looking for and it has helped you.
Stem cells become specialized cells such as blood cells because certain genes are activated and cause a particular cell to develop (Option B). It is called differentiation.
<h3>What is cellular differentiation?</h3>
Cellular differentiation refers to the process by which certain genes are expressed in a particular cell lineage.
Cellular differentiation leads to the formation of mature specialized cells that perform specific functions.
For example, immature hematopoietic stem cells become differentiated to produce mature red blood cells.
