Plants and animals are organized into levels of increasing complexity: cells, tissues, organs, organ systems, and organisms. What is one feature that is common to all levels, and how does it benefit the organism?
A
At each level, the parts of an organism (such as the skeletal system and the excretory system, or the stomach and the pancreas) are able to function independently of each other. This ensures that damage to one part does not destroy the entire organism.
B
At all levels, the parts of an organism are surrounded by outer layers (such as cell membranes and human skin) that are permeable to some extent. These outer layers form a barrier against harmful substances while allowing necessary particles to enter and exit.
C
At all levels, the parts of an organism can be repaired or replaced (for example, by growing scar tissue), or else the organism has more parts than it needs (such as two kidneys) so that it can still function if one is destroyed. This ensures that damage to one part does not destroy the entire organism.
D
At all levels, the parts of an organism are arranged in a branching pattern (such as a tree’s roots or a human hand), with increasingly smaller units branching out from a larger central unit. This arrangement allows the smaller units to spread out over a large area, while the central unit is relatively protected from harm.

such as answering phones, scheduling appointments, sending faxes, and filing documents.

explanation:

all of the following except for c.foreign government

as we know, the english language is spoken all over the world by native and non-native speakers and has become the most certain tool when it comes to communicating. businesses, schools, even romantic relationships depend on it to keep thriving. in addition, it is the language of the internet not only because most of the content available is in english, but also because people prefer to use it when talking to others, since it's the language everyone supposedly learns.

yet, there have been some current claims that chinese will soon take over as the most important language in the world. china's magnitude has never been more evident and doing business with the chinese is a gold mine for any country. we now see language schools offering chinese courses as commonly as english.

however - even though we cannot deny china's importance and the advantage it is when someone takes the time to learn the language their business contact speaks-, people in general seem to be ignoring the aspects that seem to keep english as the chosen one of languages. one of them has been mentioned above: it is the language of the internet. also, chinese people are still learning english, since it opens doors in communicating with practically everyone else, from every single country.

note: if this is not the sort of transition you need, let me know. : d

i think   they were arguing over whether they would get info from doing it or nit was invading privacy
