Answer:
True.
Explanation:
Extinction vortex is a model used by scientists to understand extinction dynamics within a community. This model allows scientists to assess and understand how a population can become highly vulnerable to elements of its habitat, becoming increasingly apt for extinction. According to this model, any organism is capable of extinction, as all are susceptible to having a gene pool that will not allow its survival, regardless of the environment.
This hypothesis is incorrect. A good hypothesis must have the word if or then. This hypothesis contains neither of these words.
Flatworms have no need for circulatory and respiratory systems because they are able to actively diffuse oxygen through their skin and their body layout is such that they do not need to transport oxygen in order for it to get to their cells.
Answer:
First image
Explanation:
You did not show the set up, but the best answer would be the first image.
Dry ice is very cold, and when it comes into contact with the warm air, it sublimates into gas, which we know as CO₂ gas. Gas takes up more space and volume that solids, so the expansion of the gas builds up pressure. Since there is not enough space in the flask, the overflows and pushes up into the balloon.
The difference in temperature between dry ice and warm air is big, so it gives the particles a big and fast boost, which splits them apart quickly. This is why it skips the liquid phase.
