Absorbing prokaryotic cells. This theory is called the endosymbiotic theory.
The early prokaryotic cells that were absorbed likely evolved into mitochondria and chloroplasts, membrane-bound organelles with their own DNA in single chromosomes and their own ribosomes.
Answer:
A. volcanic ash layers were regularly interspersed between the sedimentary strata.
Explanation:
The discovery of a fossil is a moment of accomplishment for archaeologists, hence the date dating process begins and the older the relic the greater its value for paleontology. Chemistry is present in this process, more precisely the carbon element, but other elements can be used as uranium, lead, potassium and argon.
In the case of the fossils reported in the question, to assign absolute dates to fossils in this sediment core would be most useful if volcanic ash layers were regularly interspersed between sedimentary strata because it would separate sedimentation times and allow the use of more than one element. dating, making the search more complete and the date most credible.

The way that the number of injuries per cat relate to the number of stories a cat falls is that:
- As we examine the data about cats dropping from a given number of stories, a tendency becomes obvious. The cat sustains more wounds from story one to story eight than in the previous stories combined. Despite the fact that there are fewer injuries in the last category.
<h3>Why do cats survive after jumping off of a tall building?</h3>
High-rise syndrome describes the wounds that cats can get when they fall from a steep height, like an inside second-floor landing or balcony, out a window, down a fire escape, or when they fail to jump from a landing to a higher architectural element, like a ledge or window.
Cats may live comfortably in apartments and high-rise buildings, but we must make sure they have enough stimulation and playtime.
Therefore, According to Jim Usherwood of the Royal Veterinary College's structure and motion lab, stated that cats have long, flexible legs. "They have respectable muscle mass. Since they can jump rather well, the same muscles focus their efforts on slowing down rather than shattering bones."
