Anaxyrus, woodhousii. From what I remember
Answer:
Un elemento químico es un tipo de materia constituida por átomos de la misma clase. En su forma más simple, posee un número determinado de protones en su núcleo haciéndolo pertenecer a una categoría única clasificada por su número atómico, aun cuando este pueda desplegar distintas masas atómicas.
Explanation:
Answer: Option B and C.
Heavy and continuous rains flood the land, submerging habitats.
c. Lightning strikes a tree and begins a fire that clears the land.
Explanation:
Heavy and continuous rains flood the land, submerging habitats.
Lightning strikes a tree and begins a fire that clears the land.
The above are example of density independent abiotic factors because rainfall and lightning affect the population size of the environment by decreasing it's population sizes.
Abiotic factors are the non living part of the environment and they include rain fail, temperature,lightning, humidity e.t.c.
Density independent abiotic factors are factors that decrease or increase the population size of the ecosystem.
Therefore, Heavy and continuous rains flood the land, submerging habitats.
cLightning strikes a tree and begins a fire that clears the land are density independent factor because they decrease the population size.
Answer:
The correct answer is - operation of reflex arc.
Explanation:
The reflex arc is a unique and special type of neural pathway that starts with a sensory neuron and ends with a motor neuron. In this operation sensory neuron acts as the receptor and motor neuron is effector. This type of neural circuit helps in faster response.
Voluntary muscles like quadriceps muscle are normally in control voluntarily however, such muscle may contract involuntary due to reflex arc. This type of contraction takes place before the signal has even reached the brain.
In this response the sensory neuron takes the signal to the spinal cord and then motor neuron to the effector muscle for faster response.
Thus, the correct answer is - operation of reflex arc.
