Protista organisms are most closely related to Archaebacteria.
I think that since it lives on the ocean floor, at the deepest of the ocean. So anyway, the fin on the Eurypterids is still necessary but not that much, since they live on the ocean floor. Their movements mostly on the ocean floor. So fin would not help them "stick" to the floor. Also there are still gravity acts on the Eurypterids and the feet would help them move faster. Hope this helps.
Answer I think the answer went to RNA
D: Human feet come in a wide range of sizes. There isn't a lot of gray area or space for ranges of things in medel's laws, but they still work in a lot of cases.
Answer:
Inbreeding leaves animals susceptible to genetic disease, and populations to reduced fitness. This family of three would not be able to sustain a population given their a) group dynamics and b) genetic variation
Explanation:
In small populations, the variation in genetic material is likely to be low. The consequence of this is that there is increased homozygosity. That means less members of the population carry two different alleles of a gene for any given trait. This increases the chance of the appearance of recessive traits, which could be disease causing or otherwise reduce fitness.
With only three related individuals left, the chances of generating a new and thriving population with the limited genetic material is almost non existent, especially considering the animals are a male, female and their pup
