Answer:d. All of these answers are correct.
Explanation:
-Visual aids mostly make your speech stronger as people can view what you are talking about.
-However you should be careful that they do not take over your presentation , it is very likely that you may feel inclined to look away from the audience and focus on the visual that you are explaining.
-This is not a good idea, if you are delivering a speech you want to maintain eye contact to keep audience focused on what you are delivering otherwise you may lose their attention .
-You need to occasionally or periodically look at your visuals whilst maintaining eye contact during most of your time.
-You also need to display visuals only when you are discussing them otherwise audience will focus on the visuals and not on what you are discussing at that particular moment .
-Giving visuals to the audience will also take their attention away from your speech and make them focus on visuals, they may even start discussing those visuals amongst each other .
-If you want them to take some information home from your speech , you will need to give them hardcopies of your speech at the end of your presentation
Answer: Karl Von Baer was an Estonian biologist and generalized the observations around embryology into laws bearing its name.
His laws indicate that the earlier we are in the embryonic phase, the closer the classes of distant organisms look to each other. As embryos develop, they diverge further from embryos of other species.
The von Baer sequence poses more problems for evolutionary mythology since natural selection cannot explain the pattern of embryonic development. Natural selection does not want to know if a trait is widespread or specific. It does not see attributes so it cannot sort them according to a special sequence.
