The cardiovascular system
The cardiovascular system is an
organ system which allows blood to circulate and transports nutrients, gases, hormones,
and blood cells within the cells of the body for proper functioning of human
cells and organs. The cardiovascular system is made up of the heart and the
circulatory system. A group of arteries, arterioles, and capillaries help to carry
blood from the heart to other parts of the body.
Earthquakes and Volcanoes have higher concentrations at tectonic plate boundaries. The faults at convergent and divergent boundaries are going to have more seismic activity.
Tina could use dendrochronology in her studies. Dendrochronology is the study of tree rings and scientists use this method to study past climatic conditions. Tree rings record the annual growth of the tree. A smaller than average tree ring indicates a possible drought or other climatic factor than can negatively affect the growth of trees. A larger than average ring can speak of favorable conditions for growth such as increased rainfall.
Instead, climate change was found to typically lead to local extinctions and declines by influencing interactions between species, such as reducing prey populations for predators.
Cell theory is based on microscopes, as we know cells are very small in size and cannot be seen with a naked eye, so if microscopes had not been invented, cell theory would have not been developed as it is today
Hope this helps!
