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 ↩️

What word is used to describe the reaction that uses water to break apart a large molecule?
Maru [420]
The answer is hydrolysis.

The word hydrolysis comes from two Greek words:
hydro - water
lysis - to unbind

So, hydrolysis is a reaction of breaking apart (unbinding) large molecules using water. For example, sucrose or table sugar is disaccharide made of two monosaccharides: fructose and glucose. Hydrolysis of sucrose means that water molecule  break apart sucrose, i.e. unbind fructose and glucose.

Scientist can determine the age of ancient objects by a method called radiocarbon dating. The bombardment of the upper atmospher
IRISSAK [1]

Answer:

3688.323years

Explanation:

Given-

Half life of 14C = 5730years

As we know -

A_{(t)} = A_0e^{kt}

Where

A_{(t)} = Mass of radioactive carbon after a time period "t"

A_0= initial mass of radioactive carbon

k =radioactive decay constant

t =time

First we will find the value of "k"

\frac{1}{2} = (1)*e^{k*5730}\\

On solving, we get -

e^{5730*k}= 0.5\\5730*k = ln(0.5)\\k = -0.000121

Now, when mass of 14C becomes 64% of the plant  material on earth today, then its age would be

A_{(t)} = A_0*e^{(-0.000121*t)}\\A_{(t)}= 0.64*A_0\\0.64*A_0 = A_0*e-^{(0.000121*t)}\\t = 3688.323years

Why is it important that the cells DNA is duplicated before cell division
Greeley [361]

Answer:

If the DNA wasn't duplicated, one of the daughter cells wouldn't have DNA and die.

Explanation:

The cell would split into a cell that had DNA and would survive and a cell that wouldn't survive. The one that doesn't have DNA wouldn't be able to go through cellular functions. Why? The DNA needed to direct functions wouldn't be present.
