A greenhouse gas is a gas that reflects heat in all directions while absorbing infrared radiation (IR).
The atmosphere of the earth contains greenhouse gases, which absorb solar IR and then emit it.
Along with heat from the sun that has entered the atmosphere, some of the heat emitted makes it to the earth.

---------------- is the finest material can be blasted more than 20 kilometers into the atmosphere and carried much farther downwind than the larger blocks which fall to earth on the volcano itself.
Pyroclastic materials are classified according to their size, measured in milli meters: dust (less than 0.6 mm [0.02 inch]), ash (fragments between 0.6 and 2 mm [0.02 to 0.08 inch]), cinders (fragments between 2 and 64 mm [0.08 and 2.5 inches], also known as lapilli), blocks (angular fragments greater than 64 mm), and bombs (rounded fragments greater than 64 mm).
The fluid nature of a pyroclastic flow is maintained by the turbulence of its internal gases. Both the incandescent pyroclastic particles and the rolling clouds of dust that rise above them actively liberate more gas. The expansion of these gases accounts for the nearly frictionless character of the flow as well as its great mobility and destructive power.
Pyroclastic flow, in a volcanic eruption, a fluidized mixture of hot rock fragments, hot gases, and entrapped air that moves at high speed in thick, gray-to-black, turbulent clouds that hug the ground. The temperature of the volcanic gases can reach about 600 to 700 °C (1,100 to 1,300 °F). The velocity of a flow often exceeds 100 km (60 miles) per hour and may attain speeds as great as 160 km (100 miles) per hour.

The effects of vibration loading on adipose stem cell number, viability and differentiation towards bone-forming cells
Mechanical stimulation has a significant impact on bone cell and precursor metabolism. BM or osteogenic medium (OM), which is BM augmented with 250 M ascorbic acid 2-phosphate, 5 nM dexamethasone, and 10 mM-glycerophosphate, were both used to cultivate human ASCs. The effects on attachment, viability, proliferation, alkaline phosphatase activity, and mineralization were examined after hASCs were stimulated with high frequency (50 and 100 Hz) and high magnitude (3 g) vibration for three hours each day for two weeks using a specially designed vibration loading device.
Without vibration, control cells were grown similarly. ASDWe hypothesized that vibration loading would stimulate bone-forming cell differentiation while inhibiting fat tissue differentiation in human adipose stem cells (hASCs). We created a vibration-loading device that delivers 3g of peak acceleration to cells cultured in well plates at frequencies of 50 and 100 Hz.

Dendrites of the postsynaptic neurons are the structures that receive chemical messages -neurotransmitters- from the presynaptic neurons. The correct option is D. Dendrites.
What is a synapse?
Neurons are cells that communicate with each other through the transmition of nervous impulses.
Every neuron forms connections with other neurons or with effector organs, such as the muscle. These connections are known as synapses.
Synapses can be either chemical or electrical. The most common one is the chemical synapses that involve the release of a substance known as a neurotransmitter.
During chemical synapses, when a presynaptic neuron sends information, it releases neurotransmitters. This event is done through exocytosis.
The neurotransmitter is a molecule that travels through the synaptic space forward to the dendrites of the other neuron or to the effector cell. Once the chemical reaches the postsynaptic membrane, it binds to its receptors.
This binding neurotransmitter-receptor produces excitatory postsynaptic potential, which is the depolarization of the postsynaptic cell.
Once the action potential is initiated, it spreads to the rest of the membrane, depolarizing it.
According to this framework, when two neurons communicate, the neurotransmitter released by one of them reaches the receptors located in the dendrites of the postsynaptic cell.
Dendrites are the structures that receive chemical messages from the other cells.
The correct option is D. Dendrites.

What are immature B lymphocytes? How does it undergo clonal deletion in the bone marrow?
In the bone marrow and thymus, lymphocytes are born. The names of T cells and B cells come from the organs in which they are born. T cells form in the thymus, whereas B cells form in the bone marrow of adults or the liver of fetuses in mammals.
Most mammals' bone marrow is where immature B lymphocytes are made. The B cell will die via apoptosis, also known as a clonal deletion if it fails at any stage of the maturation process. Positive selection is used in this situation. Negative selection is also used to check the autoreactivity of B cells. These B cells will perish through clonal deletion if they have a high affinity for attaching to self-antigens.

In a common reflex arc, after a sensory nerve signal is processed by interneurons in the integration center, where does the signal go next?
In a reflex arc, after a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron. The answer is motor neurons.
What is the reflex arc?
The reflex arc refers to the sequence of events since the body receives an external stimulus until it reacts.
In general terms,
1) A stimulus of varying nature reaches the body.
2) The peripheric nervous system -PNS- receives the stimulus and sends this information to the central nervous system -CNS-.
3) The CNS processes the information and sends another signal as a response to the stimulus.
Five elements compose the reflex arc, which are receptors, three types of neurons, and effectors.
The neurons involved in the mechanism are:
• Afferent or sensorial neurons
• Interneurons
• Efferent or motor neurons
Mode of Action:
Ascending branchThe stimulus reaches the body and is received by the specialized sensory receptors.
Afferent neurons, placed in the dermis and epidermis, receive this information from receptors, react and send it to the central nervous system as nerve impulses.
Descending branchInterneurons in the CNS, process the information and send a motor response.
Efferent neurons carry the response from the CNS to the effector organs, which might be either a muscle or a gland.
Finally, the target tissue responds to the stimulus as a contraction -muscle-,or as hormones release -gland-.
A motor neuron is formed by a cellular body, dendrites (cytoplasmic extensions that receive stimuli from other cells), and a long axon that is capable of conducting the electrochemical signals.
The axon brunches out into several extensions when it approaches the muscle.
At the end of each brunch, the axon is inserted in the muscle fiber surface, composing neuromuscular join.
This is the last part of the NS involved in the process before the muscle contracts.
After a sensory nerve signal is processed by interneurons in the integration center, the signal goes to the motor neuron, and from there to the effector.
The corrct answer is motorneuron.
