Answer:

Reflex action is the sudden uncontrolled reaction towards a certain stimuli eg response to hot iron

Reflex arc is the path taken by reflex action to a certain stimuli

Diagram depends to

Receptor(eg skin), receptor nerve(sensory neurone),centre reflex arc(spinal cord most of reflex action) they met relay neurone, motor neurone and ends at reflexor (eg muscle)

Identify interactions among species, such as competition or predation.

sleet_krkn [62]

Among the different types of species interactions, we can mention amensalism, commensalism, parasitism, mutualism, competition, and predation.

<h3>What are the possible interactions among species?</h3>

All organisms in nature interact with other organisms in different ways.

Amensalism

Refers to a biological relationship established between two organisms, in which one of them avoids the growth, development, or survival of the other one.

In this interaction, one of the organisms seems to be strongly affected by the other one. Meanwhile, the other organism does not seem to be affected at all.

Commensalism

In this case, the fitness of only one of the species seems to increase, while the other species is not affected at all, nor positively or negatively.

The unaffected species might provide food or refuge to the other species, which is beneficiated.

Parasitism

In this case, one of the species is beneficiated, while the other suffers a consequence, reducing its fitness.

These interactions are mainly about nutrition, although there might be other benefits too.

Some parasite species might coexist with their host, while some others might get them ill to the point of causing death.

Mutualism

The interaction is favorable for both species.

Their fitness increases with these interactions, although they do not need this relationship to survive.

The degree of benefits might vary among species or might be equal.

Competition

This is an ecological and evolutive process very common in nature.

Competition might be intra- or interspecific. Competition between different species in a community or ecosystem might be due to the same resource use.

Resources are the same food, territory, shelter, etcetera. When a resource is useful for two or more species, and limited, they compete to gain it.

One of the species is more competitive, so it is favored over the other species.

Predation

It refers to the interaction in which one species attacks, kills, and feeds on other species.

This definition excludes the detritivorous organisms, because in these last cases the organic matter is already dead.

Conduction is the transfer of heat between substances with different temperatures. Heat moves from the warmer to the cooler subs

EastWind [94]

Answer:

True.

Explanation:

Conduction is a heat transfer method. The heat passes by direct contact between two objects. The heat will go from the object with the higher temperature to the one with the lowest one. We call this temperature gradient. If we analyze the molecular aspect of conduction, we can see that the molecules with higher temperatures have more energy so, they move more. These molecules will collide with the molecules of the other object transferring their energy. As a result, heat passes from the hottest object to the cooler one till the two substances are at the same temperature, there is thermal equilibrium.
