Wittaler [7]

Answer:

the order would be:

Carnivorous animal -> scavenger animal ---> autonomous living organism ---> decomposing organisms.

Explanation:

The lion would be the carnivore, the bird that eats the waste of dead meat would be the scavenger, the vegetable the autonomous, since it does not require an external energy source to live but synthesizes its own energy and finally the decomposers fulfill the function to decompose chemical compounds to give energy to the earth, which would be useful for the growth of other living organisms. This is how the chain meets the cycle of life.

What wavelength of radiation has photons of energy 5.44 x 10-18 J?
spin [16.1K]

Answer:

λ = 37 nm

Radiation is in the ultra violet region.

Explanation:

Given data:

Energy of photon = 5.44 × 10 ⁻¹⁸ J

Wavelength of photon = ?

Solution:

E = h.c / λ

λ = h. c/ E

λ = 6.63× 10⁻³⁴m² kg/s × 3×10⁸ m/s / 5.44 × 10 ⁻¹⁸ Kg m²/s²

λ = 19.89 × 10⁻²⁶ kg. m³ /s² / 5.44 × 10 ⁻¹⁸ Kg m²/s²

λ = 3.7 × 10⁻⁸ m

m to nm conversion.

λ = 3.7 × 10⁻⁸m ×10⁹ nm / 1m

λ = 37 nm

Radiation is in the ultra violet region because the rage of UV is 1 nm - 400 nm.

The cell bodies of sensory neurons that are in clusters of neurons outside the spinal cord are called ____.
Nonamiya [84]

Answer:

The cell bodies of sensory neurons that are in clusters of neurons outside the spinal cord are called  ____

The answer is "dorsal root ganglia"

Explanation:

Explanations of some terms

Sensory neurons:

Sensory neurons, also known as afferent neurons, have cell bodies that are located in the dorsal ganglia (also known as  spinal ganglia) of the spinal cord. Most sensory neurons have one axon which is split into two branches, they transmit impulses toward the spinal cord.

Spinal cord:

The spinal cord is a tubular structure composed of nervous tissue housed within the vertebral column, runs from the base of the brain to the lower spine. Spinal cord is a component of the Central Nervous System that serves as information highway the between brain and the body which Integrates and processes information. It can function with the brain and can also function independently of the brain.

Dorsal root ganglia:

Dorsal root ganglia also known as dorsal ganglia originated as bipolar cells. They exists within the peripheral nervous system and they have special nerve cell clusters that aid in transmitting the sensory messages of pain and touch. The dorsal root ganglia receive information from sensory receptor organs and transmitting the information to the central nervous system.
