B has the most mass. You can see this because it already sunk due to it being the heaviest. The block with the least mass is A, because you can see it’s sticking out of the water the most since it’s lighter, and the block with the medium amount of mass is C, since it’s partially in the water and partially underwater. Hope this helps :)

How does the theory of endosymbiosis differ from the autogenous and horizontal gene transfer theories in explaining the evolutio

Llana [10]

<h3>Answer and Explanation;</h3>

Endosymbiotic theory explains the origin of chloroplasts and mitochondria and their double membrane. Mitochondria of eukaryotes evolved from aerobic bacteria living within their host cell and the chloroplasts of eukaryotes evolved from endosymbiotic cyanobacteria.
On the other hand according to the autogenous hypothesis, mitochondria and chloroplasts have evolved within the protoeukaryote cell by compartmentalizing plasmids or vesicles of DNA within a pinched off invagination of the cell membrane.

Endosymbiont theory is the theory that suggests that simple prokaryotic cells were engulfed by larger prokaryotes 1.5 billion years ago.
Autogenous theory is a theory that was proposed as an alternative to endosymbiont theory. proposes that eukaryotic organelles formed by infolding of the plasma membrane.
Horizontal gene transfer theory is an alternative to endosymbiont and autogenous theories for the origin of complex organelles in eukaryotes.

What errors exist in the table below?

Vera_Pavlovna [14]

Answer:

A. spiral galaxies are not pinwheel-shaped

Explanation:

There are three types of galaxies that include spiral galaxy, elliptical galaxy and irregular galaxy.

Elliptical galaxies are round shaped as well as elongated. Elliptical galaxies have both old and new stars but mostly it contains old stars.

Spiral galaxies are pinwheel-shaped due to the regular spinning motion of dust, stars and gas around the galactic center, at speeds of hundreds of kilometers per second which allows the matter to take a pinwheel-shape. Spiral galaxies are made up of lot of gas and dust and forms many new stars which allows the spiral galaxy to shine bright.

Irregular galaxies do not have any definite shape because of the gravitational influence of close galaxies. They also have many new stars.

Hence, the error is foudn in first sentence, where it says that spiral galaxies are not pinwheel shaped. so teh correct option is A.
