Why do the products of genetic engineering must undergo many tests before they can be sold​
VashaNatasha [74]

if they did something wrong while doing it: for example, if they were supposed to make your future baby's hair pink but instead it made your baby be bald forever, this will be very harmful to the communities. they will lose a lot of money and receive lots of hate.

How to explain natural selection?
loris [4]
Natural selection is basically when organisms with the best traits survive and pass on their good traits to their offspring so that they will adapt easily and survive. Organisms who do not have ‘good traits’ that help them adapt and escape predators will be killed or eaten before they reproduce.
So in the end, natural selection is a form of evolution that allows the ‘fittest’ animals to survive and reproduce, while weeding out the unfit.

1. Flowering plants and bees have influenced each other's evolution, providing an example of
Doss [256]

Answer:

1. coevolution

2. abiogenesis

3. Endosymbiont Theory

4. It's estimated that over 99 percent of the species that have existed on Earth at some point in time are extinct today.

5. Coevolution implies that the evolution of one species is dependent on and works in relation to the evolution of another species. This may cause positive or negative impacts and could be beneficial to both organisms or only to one.

6. This theory states that the first building block of life that allowed for reproduction of organisms was the development of self-replicating RNA. This hasn't been able to be fully demonstrated in any science experiment but is based on the idea that there are RNAs that can catalyze biochemical reactions on their own without proteins.

7. This process points to the development of structures through the envelopment of smaller cells that perform specific functions. This is how eukaryotic cells evolved from prokaryotic cells.

8. This experiment was important because it showed that, in the right primordial soup, organic compounds could develop from inorganic compounds.
