Dafna1 [17]

Answer:

The correct answer is option D. A condition of people whose gender at birth is contrary to the one they identify with.

Explanation:

Gender dysphoria is a type of disorder where a person does not feel comfortable with the physical sex that was assigned at birth, but feels that it belongs to the opposite gender.

This type of disorder generates a significant clinical discomfort or a feeling of not fitting socially.

Gender dysphoria began being treated as a <u>psychiatric illness</u>, although this <u>was ruled out by WHO</u>. After being cataloged in the category of sexual disorders, it was recategorized and it started to have<u> its own category</u>, which today is known as <u>gender dysphoria</u>, where it is established that it is not a mental illness itself but that it is a feeling of clinical discomfort in As for the condition of gender.

Currently, it is still considered a disorder, and not a disease, although there are many groups that require it to stop being treated as such, although they do not have medical evidence to support this request.

The sugar glider in Australia and the flying squirrel in North America are both small mammals with large expanses of loose skin
Flauer [41]

Answer:

Each have adapted in very similar ways to similar habitats.

Explanation:

According to Darwin, given a similar set of conditions, two different organisms can adapt in the same direction. Here, the sugar glider inhabits Australia and the flying squirrel inhabits North America. There is a huge distance between their locations and also they are two different species with no direct evolutionary relation. However, because of the similar conditions present in their habitats, they developed same traits over the time. Both of them live in forested areas so they developed loose skin between their limbs which allowed them to glide freely between the trees.
