Answer:
The earliest civilizations developed between 4000 and 3000 B.C.E., when the rise of agriculture and trade allowed people to have surplus food and economic stability. Many people no longer had to practice farming, allowing a diverse array of professions and interests to flourish in a relatively confined area.
Explanation:
While modern civilizations extend to every continent except Antarctica, most scholars place the earliest cradles of civilizations—in other words, where civilizations first emerged—in modern-day Iraq, Egypt, India, China, Peru and Mexico, beginning between approximately 4000 and 3000 B.C.
Answer:
Weather refers to short-term atmospheric fluctuations, whereas climate explains the weather in a certain place over a long period of time.
Explanation:
Globally, weather conditions are measured at hundreds of locations every day of the year by observers and automated stations. Some remarks are made every hour, others perhaps once a day. In the long run, these weather observations allow us to quantify average long-term conditions, giving an insight into the climate of the region.
Systemic weather records have been recorded for over 140 years in various places in the United States. We can recognize patterns and trends with these long-term records. And it's our mission to collect, monitor, and arrange these data, as the official repository of the Nation for environmental data, for scientists, decision-makers, and you online.
Answer:
The similarity they have is that they both produce two identical cells to each other and to the mother cell, but the mechanism is totally different as binary fission takes place in prokaryotic cells while mitosis takes place in eukaryotic ones.
I think it’s 2 I’m not 100% sure though
Answer:
A) 50%
B) 25%
C) Same 25%
Explanation:
a) Smith parents should be heterozygous to the eye color gene, this means, they each should carry a copy of the “brown eye” gene (that we will call B), and one of the “blue eyed” one (that we will call b). Since the blue eye is a recessive trait, you can assume that they both inherited b genes to the daughter. If we draw a Punnet square (Bb vs Bb), we will see the possibilities of Smith having a copy of the blue eye gene (Bb), and it is 50%.
b) Again, with a Punnet square (Bb vs bb) we see that the possibility of having a blue eyed baby is 50% IF Smith carries the copy of the b gene. But since that possibility is established to be 50%, therefore the possibility of the baby to have blue eyes is reduced by half to 25%
c) The probability is the same, it does not have an additive effect, so there is no effect on the number of children
