Answer:

organelles are very similar to present-day bacteria, suggesting a common ancestor.

Explanation:

Some evidence suggests that some organelles like mitochondria and chloroplasts within eukaryotes were once used to be independent eukaryotes.

Endosymbiosis theory says that ancestral prokaryotic cells engulfed bacteria like cyanobacteria which with time evolved into mitochondria and chloroplast. Molecular evidence also proves that these organelles were once prokaryotic organisms because they show similar genetic makeup and ribosome type.

So these organelles are similar to present-day bacteria showing that they have a common ancestor.

Can humans live underwater what are some things to consider
timurjin [86]

Underwater living faces many of the same life support challenges as living in space. ... But in the future, underwater habitats might provide their own oxygen with artificial gill technology to extract dissolved air from the sea water

Since humans do not have gills, we cannot extract oxygen from water. Some marine mammals, like whales and dolphins, do live in water, but they don't breathe it. They have developed a mechanism to hold their breath for long periods of time underwater.

To put these depths into perspective, three American football fields laid end to end would measure 900 feet (274.32 m) long — less than the distance these divers reached underwater. Most recreational scuba divers only dive as deep as 130 feet (40 meters), according to the Professional Association of Diving Instructors.

In eukaryotic cells, DNA is packaged with proteins into structures called chromosomes. What advantage do chromosomes provide the
Vadim26 [7]

Answer:

Option C, They allow random distribution of genetic material when a cell divides.

Explanation:

The chromatin are responsible for packaging of DNA molecule into smaller space with in a chromosome. It not only package it but also protect it from. Packaging allows for easier division of cells during mitosis and meiosis and hence prevent any kind of damage to the DNA.  

Chromosomes make recombination and random segregation of genetic material to form new cells.  Each new cell gets equal number of chromosomes

Hence, option C is correction
