Option D because Earth is closer to the sun than Mars
Answer:
There is less biodiversity in the ecosystem.
Explanation:
Since the barren ground doesn't provide suitable living conditions for most of the living organisms, the ones that need the lest resources to survive create the primary succession, usually the mosses and lichens. The organisms of the primary succession provide biomass, so the ground is mixing with it, thus new soil is forming.
Answer:
<em>The correct option is d) distal humerus fracture</em>
Explanation:
The humerus is one of the three bones which join to make up the elbow joint. A break in the lower end part of the upper elbow results in distal humerus fracture. Such types of events are caused due to high energy collisions such as during an accident. The distal humerus fracture can be treated through a surgery. During the surgery, the normal motion of the humerus is tried to be restored.
Prokaryotes have a significant role in decomposition of organic matter, bringing back key nutrients into the trophic network. By decomposing dead plant or animal parts, they enable the circulation of elements like phosphorus and sodium.
On the other hand, specialized bacteria have a role in transforming nitrogen compounds in the soil, converting them into chemical forms that are suitable for other organisms to use.
Answer:
myofibril bulbous end of axon and skeletal muscles fibres.
Explanation:o
It represents the chemical synapse of the axon bulbous ends of the motor neuron ( motor end plate) and the skeletal Muscle fibres.
The influx of calcium ions into the bulbous ends leads to the fusion and empty of the vesicles containing neurotransmitters into the synaptic cleft.
The Neurotransmitters binds to the receptors on the muscles membrane to allow the transmission of action potential ( PSIP or PSEP)across the synaptic gap to the muscles fibers to initiate their contraction or relaxation.
