in the course of fish evolution, two of the gill slits slowly advanced into the jaws.
The evolution of fish started about 530 million years in the past at some point during the Cambrian explosion. It become during this time that the early chordates advanced the cranium and the vertebral column, main to the first craniates and vertebrates. the first fish lineages belong to the Agnatha or jawless fish.
The earliest fish, corresponding to living hagfish, developed about 550 million years in the past. Diversifications that in the end advanced in fish include an entire vertebral column, jaws, and an endoskeleton manufactured from bones in preference to cartilage. Fish live in the course of the sea and in freshwater lakes and streams.
New studies have uncovered the genetic foundation of gill covers in fish, which came about over 430 million years ago. It sheds light on one of the most essential evolutionary traits for fish, in addition to over vertebrates.
In jawless fishes, a sequence of gills opened behind the mouth, and those gills became supported by way of cartilaginous elements. the primary set of these elements surrounded the mouth to shape the jaw.

Answer:
b. most research in social psychology builds off of prior research relatively slowly and systematically
Explanation:
Social psychology studies the psychology of a group of individuals in a called a society. Social psychologists studies the effect that the group has on the individual and the effect that the individual has on the group.
Social psychologists hypothesize how and why the effects take place. Then these hypothesis are tested by the social psychologist who first proposed the hypothesis, then if the hypothesis holds true the hypothesis is accepted.
This hypothesis is then tested in different situations and if the hypothesis still holds true the hypothesis becomes accepted widely. If the hypothesis does not hold true modifications are suggested after which the modified hypothesis is tested. If the modified hypothesis holds true then the modified hypothesis is accepted and the previous hypothesis is corrected.
Answer: No, the salesperson is not telling you the truth.
Explanation:
Reasons are;
1) The exact number of pictures a phone of (X) memory cannot be determined due to the fact that pictures have carrying qualities and consequently would occupy varrying amount of space.
2) 10,000 pictures may or may not be stored in a 8gb memory phone, only an estimate can be given as the phone camera does not have the capacity to compress pictures to exact file sizes.
