Early scientists believed that the Earth was flat, based on observations and theories available at the time. It wasn't until later advancements in science, such as the observations of celestial bodies and exploration of new lands, that the understanding of the Earth's shape evolved to being round.
The planet human being's can possibly live on besides-planet earth, Well scientists don't know for sure because scientists are not always correct no offense to scientists though. Well that's my answer!
By being a scientists.
Yes, it is possible for parents and their children to have different Rh factors. Each parent contributes one Rh factor gene, which can result in children having a different Rh factor than their parents.
They use X-Rays from the stars being sucked into them.

So scientists can know for certain if the factor they're testing affects the outcome and isn't caused by another factor which isn't being measured. It elimiantes the chance of another factor affecting the outcome of an experiment.
They are available on the official X Factor website for the version you wish to apply for. They are only available during the time applications are being accepted.
The name of the factor that scientists change in an experiment is called the independent variable. It is the variable that is deliberately manipulated or adjusted to observe its effect on the dependent variable, which is the outcome being measured.
Scientists have not yet been able to produce a living cell from scratch because they have not been able to replicate the complex organization and self-replicating abilities of natural cells. The interplay between the various components within a living cell, as well as the precise regulation of cellular processes, is still not fully understood or replicable in synthetic systems.
The factor that scientists change or manipulate during an experiment is called the independent variable. It is the variable being tested to see how it affects the dependent variable, which is the variable being measured or observed. By manipulating the independent variable, scientists can analyze its impact on the dependent variable and draw conclusions about their relationship.
Scientists have not been able to create a living cell from scratch because the exact conditions and sequence of events that led to the first living cell's formation on Earth have not been fully understood. Additionally, the complexity of biological systems and the interactions between various molecules within a cell make it challenging to replicate these processes in a lab setting.
the factor not being answered is the control
scientists realized that beaches were being polluted when they studied them ............isn't that obvious .
