The correct answer is false. Extinction of organisms is not solely cause by man. Even way before, extinction is already happening. It can be caused by natural or human causes. Natural causes includes volcanic eruptions, earthquakes, floods, etc.
I can’t see your answer choices, but igneous rocks are made from cooled lava or magma. This is why these rocks are so brittle and grainy. I’ve attached a helpful image to better explain! Good luck!!!
The answer is B. Paleozoic
This era was the first era where insects, amphibians, and reptiles roamed the Earth.
Hope this helps!
No,not all organs are weighed on a triple beam balance.
<u>Explanation:</u>
- Usually smaller sized organs like adrenals, thyroid are commonly used to be weighed on triple beam balance, whereas larger organs like lungs, liver and heart can only be weighed on grocer's scale.
- Only weight of the smaller body organs can be measured very precisely with the help of triple beam balance, where as if we measure the weight of the larger organs using the same triple beam balance,then the resultant value thus obtained will not be accurate enough.
- Hence organs are weighed on a triple beam balance.
