Answer:
Coral!
Explanation:
I learned this is a biology class a while ago!
Although they are radically symmetrical,echinoderms are more closely related to human than to a jellyfish because they are biltarian.
Answer:
Parasitic
Explanation:
The plants that are described are typical example of parasitic plants. These types of plants have a parasitic relationship with the other plants, at least with the ones that they can use. In order for them to grow, survive, and prosper, these plants need a host plant. They attach to the host plant's steam with their miniature claw like organs, and use them for support to grow upwards, but also to extract nutrients from the host plant. While this leads to to parasitic plant's survival and prospering, the host plant is suffering, and gradually the parasitic plant will suck every nutrient out of the host plant and kill it. Without a host plant, these plants would find it extremely hard to survive, and the chances are very high that they will die because they are not well suited to get nutrient on their own.
The heat from the bonfire is transferred to the student's hands mainly, but not exclusively, through the process of RADIATION.
There are three mechanisms or processes of heat transfer: conduction, convection, and ratiation.
Conduction is carreid out by contact; it requires that the two objects are touching each other. This is not the case.
Convection is the heat transferred by the movement of the fluids (liquids ang gases). In some extent this happens in this case, but it is not the dominant effect becasue air is not a very good conductor. Specially if there is not much air movement (wind).
Thermal radiation is carried out by electromagnetic waves. When there is a source of intense heat, like the fire, the heat is propagated by radiation.
Then really, the heat from the bonfire gets to the student's hands by convection and radiation, but as fire is very intense (its temperature is very high), and as long as the air is calmed, the dominant process is radiation. If there is wind, convection starts to be important.
