The MOST distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is
Ugo [173]

The most distinctive feature of ape dentition, which clearly distinguishes apes from Old World monkeys, is a Y-5 molar pattern.

<h3>What is the Y-5 molar pattern?</h3>
  • This is a distinctive type of molar teeth pattern found in apes and hominoids.
  • In this, 5 cusps or raised surfaces are present on the grinding surface of teeth, roughly forming a Y- shape. Therefore, this is also known as Y-5 pattern.
  • Whereas Old world monkeys have only 4 cusps on their lower molars present in a bilophodont pattern.
  • A Y-5 molar is formed when the tooth is divided into different pieces which form the complete structure of the tooth.
  • In bilophodont pattern the tooth is divided into 2 symmetric sections.
  • The dental formula of apes is 2.1.2.3/2.1.2.3 i.e. 2 incisors, 1 canine, 2 premolars, 3 molars.

What do we mean when we say that there is a "Consilience of Evidence" supporting a theory?
Gnoma [55]

The correct answer is C) That scientists who have worked on the theory have independently and repeatedly come to the same conclusions over time.

Explanation:

In science, the term "consilience of evidence" is used when the evidence of a hypothesis or theory is consistent especially evidence from independent scientists or sources. This often implies the theory has been tested many times and by different experts and even using different methods but the results are always the same. This consilience of evidence is essential to declare a theory as valid and concluding. In this context, the option that describes the meaning of this term is C.

Describe how water
Alla [95]

Explanation:

Epipelagic zone, the topmost at the surface of the oceans receives most of the sunlight and most penetrating light rays diffuse in this layer. The temperatures at this zone, therefore, is warmer than zones below. This zone has lowest water pressure becaue there is little water column above it.

The deeper you get into the water the penetration of sunlight decreases. This is because the rays are greatly diffused even before they get to the deepest zones. The abyssalpelagic zone virtually receives no sunlight because the rays cannot get to this zone. This zone is, therefore, pitch dark and also the coldest. The deeper you get into the ocean the higher the water pressure due to the weight of the able water column. The water pressure is, therefore, highest in the  abyssalpelagic zone.
