The groups of small cells better than one large cell at moving material in and out because they have a greater surface-to-volume ratio.

Option: A

Explanation:

This happened so as these smaller cells, unlike bigger cells, can quickly and willingly enter and move through the membranes of other cell membranes and permeable coverings. For these smaller and mini cells, it is also important to penetrate and move effectively, distribute and transport products and materials such as nutrients, oxygen and waste across the body without requiring enough energy and saving less space. They are cheaper, more effective and use less room for simple reasons, and most notably deplete less resources.

The sugar glider in Australia and the flying squirrel in North America are both small mammals with large expanses of loose skin

Flauer [41]

Answer:

Each have adapted in very similar ways to similar habitats.

Explanation:

According to Darwin, given a similar set of conditions, two different organisms can adapt in the same direction. Here, the sugar glider inhabits Australia and the flying squirrel inhabits North America. There is a huge distance between their locations and also they are two different species with no direct evolutionary relation. However, because of the similar conditions present in their habitats, they developed same traits over the time. Both of them live in forested areas so they developed loose skin between their limbs which allowed them to glide freely between the trees.

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.

Creators who "level" communicate purposefully, honestly, and responsibly.

vredina [299]

This is incredibly true. The top way to level up, or receive a promotion, is to have proper communication. The three most important things to keep in mind to have effective communication so you may move forward is to be purposeful, be responsible in what and how you communicate, and to always be honest and up front.
