why and how do humans exist when (eventually) we're all just gonna die, either by mass extinction or we just... die out?

Answers

Answer:

The short answer is yes. The fossil record shows everything goes extinct, eventually. Almost all species that ever lived, over 99.9%, are extinct.

Humans have vulnerabilities. Large, warm-blooded animals like us don’t handle ecological disruptions well. Small, cold-blooded turtles and snakes can last months without food, so they survived. Big animals with fast metabolisms – tyrannosaurs, or humans – require lots of food, constantly.

So we’re vulnerable, but there are reasons to think humans are resistant to extinction, maybe uniquely so. We’re a deeply strange species – widespread, abundant, supremely adoptable – which all suggest we’ll stick around for a while

A large company is interested in opening an on-site gym for the employees and would like to know what hours the employees would prefer to have the gym open.

Which data collection method would provide an unbiased sample?

a.)
Emailing a questionnaire to the employees
b.)
Asking all employees who work from 8am - 5pm
c.)
Posting a request for survey volunteers in the company's breakroom
d.)
Asking five random employees from each shift

Answers

The data collection method that would provide an unbiased sample is "asking five random employees from each shift"

An unbiased sample is a sample whereby all the individuals have and equal chance of being picked for the research study.

In this case, asking five random employees from each shift is an unbiased sampling as everyone has an equal chance of being picked.

Option A is incorrect. Emailing a questionnaire to all the employees will be costly and isn't sampling.

Option B is incorrect. Asking all employees who work from 8am - 5pm is bias as others that doesn't work within the time frame aren't taken into consideration.

Option C is incorrect. Posting a request for the survey volunteers that are in the company's breakroom is biased.

Therefore, the correct option is D.

Why do you say that the child's sex role identify is acquired through socialization and not determined by his or her genes?

Answers

Answer:

We say this because:

Explanation: A child's genes affect their body parts, hormones, and physical things that may help them identify themselves as a specific gender. This does not affect their brain. Their gender is what their brain identifies them as. Unless you are 100% a girl, who thinks they are a boy (and vice versa), then you will be the gender you identify as.
