Jenna made this model to show the processes which resulted in the formation of oceans. which of these statements best describes a flaw in jenna's model? water filled the basins after sea floor spreading. water filled the basins after segments of earth's crust moved. earth's crust was formed after water filled the basins. earth's crusts were broken down after the process of sea floor spreading.

The answer is Earth's crust was formed after water filled the basins.

There is a flaw in this statement because the earth’s crust is the top-most layer of the earth that occurs across the whole of the earth. Actually, the reverse happens, the oceans sit on top earth’s crust therefore cannot be formed after water filled the basins.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.

the diploid number of chromosomes is sometimes represented by the symbol 2n. for the fruit fly, the diploid number is 8, which can be written as 2n = 8, where n represents twice the number of chromosomes in a sperm or egg cell.
