I am going to be honest i’m good at chemistry but i need the point cause i need help on my history work
Answer:
C. A technological society has both a positive and negative impact on the environment
Explanation:
It is correct to suggest and to acclaim that a technological society has both a positive and negative impact on the environment.
The environment is the region of space where living organisms and non-living components can be found.
- Technology no doubt has opened up our knowledge about the environment.
- We are now aware of very topical issues that affects the environment and how to combat them.
- On the other side, technological advance has also bode poorly for the environment.
- New chemical wastes generated by industrial processes have proven very costly to the environment.
We see that technology has both negative and positive effects on the environment.
Answer:
nonvascular because it lacks stems
Explanation:
Non-vascular plants, or bryophytes, are almost the most primitive forms of land vegetation. They lack the vascular tissue system (xylem and phloem) needed for transporting water and nutrients. Unlike angiosperms, non-vascular plants do not produce flowers, fruit, or seeds. They also lack true leaves, roots, and stems. Non-vascular plants are usually small, green mats of vegetation found in damp (wet) habitats. The lack of vascular tissue means that such plants must remain around moist environments.Just like other plants, non-vascular plants exhibit alternation of generations and cycle between sexual and asexual reproductive phases. The three main divisions of bryophytes are: Bryophyta (mosses), Hapatophyta (liverworts), and Anthocerotophyta (hornworts).
Answer : 0.125 M
Explanation : The definition of osmotic pressure is "<span><em>the pressure can be applied on a pure solvent to prevent it passing into a given solution by osmosis</em>".
</span>
So according to this definition, osmotic pressure can be called as directly proportional to the concentration of the solution and hence the pressure can also be directly proportional to the concentration.
Hence, if pressure is getting decreased from 28 to 7 it means it got decreased by 4 times;
28 / 7 = 4 that means;
So the concentration will be also decreased by 4 times so, 0.50 / 4 = 0.125 M
