The right answer is C. Silt is more vulnerable...

In geology, a silt is a sedimentary formation whose grains are of intermediate size between clays and sands that is to say between 2 and 63 micrometers (the precise limits may vary somewhat according to the laboratories). A mostly silty deposit may be called silt. In geology, Anglicism silt is often used to designate silts.

The silt is the ultimate product of fluvial erosion of the rocks of the river catchment. The silty particles thus consist of very fine debris of quartz, mica and feldspar, or even clay minerals.

Stringers characterize the loess deposits of loess, also known as "slime plateaus", and are common in alluvial deposits. In the latter case, the silty particles release nutrients which have a major interest for the renewal of soil fertility and therefore for their agricultural exploitation.

Since silt is often suspended in water, it can contribute to its turbidity.

Answer:

Option number 2 is correct. When you talk together in a group during a laboratory exercise, you are engaging in classroom scientific communication.

Explanation:

Any type of communication that is made regarding science is described as a scientific communication. This kind of communication generally involves talks about research, recent advances in any scientific topics or techniques, observations that one might have made on a particular science topic, asking another person about any science-related topic or techniques, etc.

If a scientist talks about any science topic to the public, then it would be a public scientific communication. A scientific communication made among scientists would be termed as professional scientific communication. Any science based communication that is made and kept private would be termed as private scientific communication.

Hence, option 2 is correct. A science based communication between students in a lab would be classroom scientific communication.

Xelga [282]

Answer:

I agree and disagree with his statement.

Explanation:

We all know that the blood type AB is the universal recipient, so we know that this bloodtype can recieve any kind of blood. AB-type blood doesn't fight off anything because it has all of the antibodies needed. We also know that type O is the universal donor, meaning that this blood can be donated to anyone. This bloodtype doesn't have antibodies, so nothing will go wrong. However, for the other bloodtypes, yes, things have to be matched carefully. Type B blood can't be given type A blood, and so on. Another thing you have to think about is the Rh factor, which is the +/- after blood types. Rh+ bloodtypes can recieve both Rh+ and Rh- bloodtypes, but Rh- bloodtypes can only recieve Rh- bloodtypes. There are also graphic tables that will help answer this question if you're a visual learner!

I hope this helps, sorry it was a bit late!
