Answer:
c. mutation and natural selection
Explanation:
The major forces causing the genetic divergence of the two populations are <u>mutation and natural selection</u>. Natural selection results when organisms adapt to a prevailing environmental condition, those who are unable to adapt, die out. The adaptation for survival is passed on to the next generation. mutation on the other hand is a change in gene structure which results in a new variation in the population. This variation can be passed to the next generation.
Answer:
d. all of these answers
Explanation:
RFID is radio frequency identification which uses the concept of electromagnetism to track and identify the tags that are attached to it. RFID contains electronic chips that stores information. The radio transmission waves transmitted by the chip allows the object to be tracked.
It is useful in many applications. It will help track and locate the missing children when they are lost when the tags are attached to the children. It can also help the law enforcement people to track down criminals by receiving the radio signals from them. It has its application in hospitals in tracking patients records and conditions. Thus it has numerous applications.
Hence the correct option is -- option (d)

Answer:
Moches: Well developed and established irrigation channels and creation of labor classes
Chimus: Planning to build cities, messaging system.
Explanation:
Moches and Chimus are civilizations that predated the Incas, but that contributed in a great way to the establishment and success of the Inca culture.
The moches influenced the Incas to develop and establish efficient irrigation channels that would allow an advance in agriculture, generating more wealth and an efficient trade. It also influenced the creation of labor classes, allowing the collection of taxes to be equivalent to social class and that no one could be exploited.
The Chimus, in turn, influenced the Incas to plan the construction of new cities very well, with major works that showed the wealth of the empire, in addition to providing comfort to the population. They also influenced a system for transmitting messages through corridors, which was very modern and efficient at the time.
I will discuss each of them in turn:
Their use will make a bad presentation good.
-no, this is false: just inserting graphics will not save a bad presentation.
There should be at least one graphic element on each slide.
-this is also false: the decision whether there should be a graphic depends on the content of the presentation!!!
They should be appropriate and relevant to
the presentation's content.
-yes, this is true and probably the most important rule!
They should be large enough to be seen by
your audience.
-this is correct! if they can't be seen then they're only confusing the audience!!!
They should only be used when they enhance the content of
the presentation.
-this is also true!
