The fourth sequence in the title box is the awnser to the first one in the pairs box
Answer:
d. all of these
Explanation:
Over the past century, many researchers have questioned whether nonhuman primates could communicate with each other and whether they could communicate with each other. After much research and testing with different nonhuman primates, it was concluded that primates not only communicate, but this communication is done through various processes and has a similar pace to the rate of communication between humans, after all, if genetic differences between humans and chimpanzees are very small.
Among the processes of communication between non-human primates we can mention: vocalization, facial expressions and displays, which ensure that these animals talk to each other.
It has been projected that by 2025 b. 2 out of 3 people will suffer from water shortages.
The problem of shortage of water will happen to the altered weather patterns, depletion of ground water, pollution of water, and due to demand-supply problem in increased population sizes of humans. The present scenario is emphasizing more on the sustainable use of water for agricultural and industrial purposes to promote water conservation. This will reduce the proportion of affected people in the future.
The correct answer is: d. it contains many light-sensing columns called ommatidia
Ommatidia are units that form compound eyes of arthropods such as insects, crustaceans and millipedes (these are invertebrates) and make them very sensitive to motion. Ommatidia are composed of photoreceptor cells (visual detection) surrounded by support cells and pigment cells.
The eyes of vertebrates are more complex showing that progressive improvements in the structure of the eye occurred during the evolution.
