The previous statement is true because if a substance cannot get into a cell membrane it is assisted via protein channels however if it doesn't need the protein channels then it just flows through the membrane.
Fossils can give information about past environmental conditions by showing the type of animal they belonged to. If a scientist found a whale fossil in a desert, he/she could assume that the desert was once an ocean as whales only live in oceans. If someone found a fossil of a lizard that inhabited trees, in the middle of the ocean, then he/she could assume that the ocean didn't exist at one point and instead, there might have been a forest in it's place.
Hope this helps!

Second, it must find a way to conserve heat when temperatures in the environment are too cold. Third, it must find a way to get rid of extra heat when temperatures in the environment are too hot.
The step that forms part of the engineering process but is not part of a scientific investigation is designing a solution.
<h3>What is the scientific process?</h3>
The scientific process refers to a series of steps called the scientific method which is used to collect empirical evidence and thus test hypotheses.
The engineering process is aimed at finding a solution to problems found in daily issues, which does not correspond to science and the scientific method.
In conclusion, the step that forms part of the engineering process but is not part of a scientific investigation is designing a solution.
