In your opinion, how important are first impressions? How can first impressions be
misleading? Have you ever judged someone based on a first impression? Explain your
answer

Answers

Here's the answer. Just be yourself for first impressions lol

Answer:

First impressions are important to me. You can figure a lot about a person just from how they first act when they meet you. First impressions are crucial. They can make or break an opportunity. It's human nature to make a judgement about someone when you first meet them, but did you know that people can formulate an opinion about you in less than 20 seconds! They are misleading however because some people take time to warm up and their personality may change after being around them for some time. I personally judge many people on my first impression of them but I try to keep an open mind. If I end up not liking someone after a few impressions, that tie is cut as I don't want to associate with someone I dont like.

Why are adolescence at higher risk of transmitting the most common STDs?

Answers

Answer:

They are at higher risk because of hormones. During adolescence, you go through different hormonal changes, including sexual ones. These sexual changes may result in developing different urges such as masturbation. However, the problem comes with a lack of proper sexual education and how most of their knowledge on sex is based off of myths perpetuated by peers. So it's really a lack of education on sexual reproduction and the transmission of diseases.

Answer:

From a biological perspective, adolescent females are particularly susceptible to STIs like CT and HPV due to lower production of cervical mucous and increased cervical ectopy [2, 4]. Therefore, if exposed to an STI, adolescent females are more likely than adults to get infected.
