Answer:
A tetrad is a four part structure formed during the prophase I of meiosis I which is formed by the homologous chromosomes which is composed of two identical chromatids.
The tetrad formation takes place when a proteinaceous meiosis-specific nuclear structures called synaptonemal complex is formed between two homologous chromosomes which mediates the tight associations of the homologous chromosomes.
The synaptonemal complex consists of two ladder like lateral elements which attaches the chromatin of the homologius chromosomes. The central region of the synaptonemal complex is composed of the transverse filaments and the central element which bridge the space between the the lateral elements.
This attachment of the chromatin to the synaptonemal complex mediates the chromosome pairing and form tetrad.
D
Answer:
The answer is C they are members of the same species.
A) it isn't correct because they are both the same species which means the same scientific name
B) wasn't even close to being correct, Archaea is part of Prokaryotes which doesn't have a nucleus and they reproduce asexually meaning only one which is making their own offspring that we call clones
D) isn't correct because genus is the same as species
Hope this is correct :)
Answer:
The nucleus replicates.
Explanation:
Replication of the nucleus does not happen during interphase.

The correct answer to this open question is the following.
With the above-mentioned description, we can assume that the animal is a polar bear.
Polar bears inhabit the Arctic. It is a beautiful bear species that live in extremely cold and icy places. That is why they have the white characteristic fur to protect them from extremely low temperatures. They are expert hunters that can hunt on land or better in the sea. They like to eat seals and other fishes. However, hunters have killed many polar bears and with the climate change issue, these bears are in danger.
