Metres are exactly 100 cm in length, the easiest way to go from metres to centimetres is to simply add the extra 1 or 2 zeros, so 4.5 metres would be 450 centimetres.
As for the millimetres, 1mm is equal to 0.1cm, once again, just move the decimal forward by one numeral, and you'll have the converted value, making 50mm = 5.0cm.
Your shark would be 450cm long and have teeth with an average length of 5cm.
The earth's tilt of 23.5 degrees to it's axis as it revolves around the sun causes seasons; summer, spring, winter and autumn. This is due to the orientation of the earth with respect to the sun that cause variations in how to sun rays 'strike' the earth. Consequently, there are variations in temperatures across the earth, over its complete revolution, causing seasons my brotha, Hope this helps!
Van der Waals interactions may result when electrons are not symmetrically distributed in a molecule. Van der Waals forces, in physical chemistry are essentially
associated with the name of a Dutch researcher Johannes Diderik van der Waals
and indicate the separation of dependent interactions among particles and
atoms.
Answer:
Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over time.
hope this helps:)
