Answer:
The phylum Hemichordata is the one that could form an evolutionary connection between the chordates and non-chordates.
Explanation:
To the phylum Hemichordata belongs a genus that scientists believe could explain how the chordates could evolve from the non-chordates. This genus is Balanoglossus, of the class Enteropneusta.
Balanoglossus is similar to a worm, whose habitat is the seabed, and like other hemicordates it has a stomach, a structure that forms part of its digestive system and fulfills the functions of a spine.

Explanation:
Meiosis stage was formerly called the reduction stage involving two divisions; meiosis I and II. After the first stage of meiosis, the ploidy level of each of the daughter cell changes is in an haploid state, meaning here the DNA content has been reduced by half. In humans (2n = 46), who have 23 pairs of chromosomes, the number of chromosomes is reduced by half at the end of meiosis I (n = 23). This haploid state is still maintained by the meiosis II just undergoing the normal mitosis division.
In determining species, it is best to differentiate in terms of the population that is being adapted in which, a certain niche. So, if it has a small gene pool, and the different species will be interbreeding each other with a much genetic variability in gene pool, it would most likely cause a less adaptation. The niche will be having a less adaptation if too much genetic variability will occur.
Answer:
brine flies prefer warm temperatures to breed in, more brine flies means more food for the brine shrimp, so brine shrimp will be able to breed more as there's more food. and vice versa- in colder temperatures there would be less breeding of the flies, meaning less food for shrimps. therefore less breeding of shrimps)
