Answer:

Streak is a more reliable property than color because streak does not vary. Minerals that are the same color may have a different colored streak. Many minerals, such as the quartz in the Figure above, do not have streak. ... The streak of hematite across an unglazed porcelain plate is red-brown. Malachite (MAL-uh-KYT), an ore of copper, is green. Color, however, is the least useful property for mineral identification. One reason is that many minerals have similar colors. ... Another reason not to rely on color alone is that some minerals can change color in various circumstances.

hope this helps!!!!!!!!!! Can I have brainilist pls thx :)

Arguments FOR GMOs? Arguments AGAINST GMOs?<br>​
stich3 [128]

❤️Hello!❤️ In my opinion, i'm against GMO's. First of all you need to understand what GMO stands for, GMO means (Genetically Modified Organisms) and does that REALLY sound appealing to eat (Be honest). So now we have that covered i'm going to tell you some reasons why YOU should avoid Genetically Modified Organisms (GMO's). First of all GMO's are unhealthy, according to the American Academy of Environmental Medicine. They cite animal studies showing organ damage, gastrointestinal and immune system disorders, accelerated aging, and infertility. Second of all, GMO's contaminate forever. GMO's cross pollinate and their seeds can travel. It is impossible to fully clean up our contaminated gene pool. Self propagating GMO pollution will outlast the effects of global warming and nuclear waste. The impact is huge, threatening the health of future generations. Third of all, GMO's increase herbicide use, most GMO crops are engineered to be “Herbicide tolerant”―they deadly weed killer. Monsanto, for example, sells Roundup Ready crops, designed to survive applications of their Roundup herbicide.  Between 1996 and 2008, US farmers sprayed an extra 383 million pounds of herbicide on GMO's. Overuse of Roundup results in “superweeds,” resistant to the herbicide. This is causing farmers to use even more toxic herbicides every year. ♒️ Hope this helps!♒️  ↪️ Autumn ↩️

Lakes and rivers constitute _______.
Brums [2.3K]
<span>Perhaps surprisingly, lakes and rivers constitute a tiny proportion of the world's total freshwater, so answer (b) is correct. Most of the freshwater on our planet is in fact locked up in ice and glaciers, some 68%. The majority of the rest, 30%, is actually underground, in springs and other groundwater feeders. That leaves just 2% that makes up all the rivers, lakes, ponds and other visible freshwater reservoirs that we see in our day-to-day lives.</span>
