2. Suggest two ways that reflex reactions help maintain homoeostasis in the human body.
Nata [24]
<span>One reflex reaction to maintaining homeostasis in the body is shivering. In response to cold temperatures, the muscular system moves our muscles quickly to warm them up as a rapid, short term solution for homeostasis. Another example is the withdrawal reflex, which occurs as a response to pain. Pain receptors activated by the painful stimulus activate the motor neurons in the body, which in turn contract muscles to move parts of your body away from the pain.</span>

Anit [1.1K]

Answer:

Predator-prey relation.

Explanation:

A predator is defined as an organism that hunts another individual, whereas a prey refers to the organism that is eaten by the predator. They tend to co-evolve (evolve together). <u>The prey is essential for the predator to survive, while the predator controls the prey populations by hunting some of the individuals.</u>

Predator-prey relations are interactions that occur between two species where one species (prey) represents a food source for the other species (predator).

The turtle (prey) is essential for the survival of the jaguar (<em>Panthera onca)</em>, while the jaguar controls the populations of turtles by preying upon them. Therefore, this is a predator-prey relation.

Mark you brainelest if you get this question right. At a convergent boundary between continental and oceanic crust, what feature
seropon [69]

At some convergent boundaries, an oceanic plate collides with a continental plate. Oceanic crust tends to be denser and thinner than continental crust, so the denser oceanic crust gets bent and pulled under, or subducted, beneath the lighter and thicker continental crust. This forms what is called a subduction zone.
