Dear Teen World I feel so ugly. My face is covered in spots all the time, it's sore and red. I think it is acne but why has it happened so suddenly? Will it go away? Robert, age 14 Please help
Answers
It is to be noted that the sudden development of Acne during the teenage year is very normal. This is due to a growth stage called Puberty.
Why does the above condition occur?When hormones become active throughout puberty, oil glands are stimulated. That is why acne is more common in teenagers. Because acne is partially hereditary, if other members in your family had (or have) acne, you may be more likely to get it as well.
Teens get acne as a result of hormonal changes associated with puberty. If your parents experienced acne as teenagers, chances are you will as well. Acne, for the most part, disappears by the time a person is out of their teens.
The best approach to deal with this is to consult a dermatologist and wash your face and hands often.

Which of the following is scientific concern related to creating genetically modified crops? O Herbicide resistance may spread to weedy species.
O Beneficial insects may be harmed by eating pest species.
O The monetary costs of growing genetically modified plants are significantly greater than those of traditional breeding techniques.
O Their adaptive advantages would allow them to overpower natural ecosystems
Answers
Herbicide resistance may spread to weedy species and beneficial insects may be harmed by eating pest species are scientific concerns related to creating genetically modified crops(GM crops).
Herbicide resistance is a concern because when crops are genetically modified to be resistant to a certain herbicide, it can lead to the development of herbicide-resistant weeds.
These weeds can then spread and become difficult to control, leading to increased use of herbicides and potentially harming the environment. Another concern is that beneficial insects, such as pollinators, may be harmed if they consume pest species that have been genetically modified to be toxic to those pests.
These unintended consequences can have negative impacts on the ecosystem and the food supply. The other two options are not scientific concern but an economic concern of the GM crops.

The mouth, oesophagus, stomach, small and large intestines, the rectum, and the anus are all included. Additionally, the liver, pancreas, and gallbladder are involved since they are crucial to the digestion process. Food is first chewed and combined with saliva in the mouth before moving via the oesophagus and into the stomach, where it is further broken down. After that, it proceeds into the large intestine, where water and salts are absorbed and any leftover waste is removed thru the rectum and anus.
