How do fossils provide evidence that suggest that evolution has occurred ASAP

When looking at fossils from a specific animal, with further detail it can be determined if there are any animals that are living now that could possibly be related to each other. For example it can be determined that a elephant was related to the once known mammoths simply because of how similar there bone structure was and the way they looked physically. If elephants were once mammoths then it could be suggested that after a long period of time they evolved to live in warm climate which made them lose their fur and how they became smaller in size.

1. Topographic map: I want to take a nature hike through the woods. I wonder if it is hillly?

2. Geologic Map: I want to study the physical features of my area, but also know what kinds of rocks it has.

Those should be the answers.

Answer:a) decreased chromatin condensation

Explanation:

During eukaryotic cell division a chromatin becomes obvious and it is simply a mass of genetic material made up of DNA and proteins which condenses to form chromosomes.

The chromatin primarily function in the compression the DNA into a unit so compacted that will be so tiny and can fit within the nucleus.

Chromatin condensation is driven by condensins and interactions between histones.

Condensins however, are large protein complexes whose central role in cell division is chromosome organization and segregation.

Chemical manipulation as stated above is decreases the rate of chromatin condensation.
