Answer:
PCBs and DDT are chemicals that were banned more than 30 years ago, but our air, water, land, and bodies are so contaminated that decades of cleanup efforts have yet to eliminate their threats to our health. Today, food is one of the most likely exposure routes to PCBs.
Because bacterial life cycle is very short it complete in 20 minutes to produce copies. secomdly bacterial genome is simple to be handle.
❤️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 ↩️

Answer:
False.
Explanation:
Monohybrid cross may be defined as the cross done by taking the single character at the time. The monohybrid cross explains the concept of dominance and law of segregation.
The P1 parent of monohybrid cross doesnot have completely identical genes. This can be explained by the cross shown below:
Parent Tt × tt
Gamete T t × t
Here, the parents are not identical.
Thus, the answer is falsi.
