DNA replication occurs in interphase, producing two sister chromatids
Answer:
False
Explanation:
Scientist believe that the primitive atmosphere lacked free oxygen. Oxygen is a highly reactive molecule that would have made difficult for complex macromolecules to appear and then create life. Rocks from the precambrian period support this theory.
Anaerobic cells appeared first, then photosynthesis appeared filling the atmosphere with oxygen and the aerobic organism develop cellular respiration to obtain energy, a process more efficient than anaerobic respiration.
Viruses have not a nucleus, but they have viral DNA that they can transplant into other healthy cells to infect them.
The time that it would take for the population to double is about 7 years.
<h3>What is population?</h3>
The population of an area refers to the number if people that live in that particular area per time. The life expectancy of a population is increased by adequate sanitation. When there is over population in an area, it can lead to malnutrition and decreased food production.
A density dependent factor that affects population growth is disease transmission. The countries with the highest populations in the world do not necessarily have the fastest population growth. One factor that has led to lower fertility rates in Europe and North America is educational opportunity for women.
The occurrence which is not a potential consequence of Earth reaching its global capacity is less spread of disease.
Using;
P= Poe^rt
P = 74,000
Po = 37,000
r = 0.1
Hence;
74,000 = 37,000e^0.1t
74,000/37,000 = e^0.1t
2 = e^0.1t
ln2 = 0.1t
t = ln2/0.1
t = 7 years
