Hi there!
With humanity's constant burning of fossil fuels, large amounts of carbon dioxide get pumped into the atmosphere.
Under normal circumstances (without humans), greenhouse gases are good, as they help keep heat energy in, much like a blanket.
Now, with such large amounts of carbon dioxide, too much heat is being kept inside of this blanket. Our ice caps are melting, threatening the survival of many species of animals. Along with their melting, sea levels are rising (and will keep rising).
With our increasing population, the last thing we can afford is to lose land as well.
Hope this helps.
:)
Answer:
data pour into weather models to help meteorologists forecast where the storm will go and how strong it'll get.
Explanation:
Uni = one
Cellular = Cell (obviously)
1. A. 1
2. D. paramecium
Overproduction of offspring, inherited variation, and the struggle to survive.
So: b, d, and e
Answer:
First the proprioceptors found in the tissues will capture tissue damage and the presence of a continuity solution in the skin, then these receptors will activate the afferent pathway, which is the pathway of pain, which is sensory.
This stimulus that ascends to the central nervous system activates the "flight" mechanism in the face of pain (it is also known as the withdrawal mechanism).
It is in this way that a stimulation is sent to the alpha motor neuron in the form of an action potential as an efferent pathway to the skeletal muscles of the foot and the damaged leg, so that an automatic and involuntary muscle contraction is generated in a matter of millisemas of second after the damage, so the foot is removed from the damage area.
Explanation:
The withdrawal mechanism is a reflex that the human acquires before pain, that is why it is the muscular contraction is automatic and fast once the pain occurs.
So as a summary: 1 - the proprioceptors of the damaged tissue are activated 2- the signal of tissue damage rises as afferent to the CNS 3- the CNS responds by activating a signal that will be sent by interneuronal connections to the alpha motor neuron 4- the signal arrives as potential of action to the alpha motor neuron that innervates the muscles of the surrounding area to which it is damaged 5 - the muscles contract, generating the withdrawal of the limb.
