Genetic drift is the changes in allele frequency in a gene pool. The bottleneck effect and founder effect are prime examples of genetic drift. 

Gene flow, not to be confused with genetic drift, is what happens when organisms move into or out of a population. Gene flow either eliminates or introduces new alleles to the gene pool. 

In short: 

1. Genetic Drift is the changes in allele frequency in a population. 
2. Gene Flow is the process of alleles moving from one population to another. 

I hope this helps!

Drag each label to the correct location on the image.
Fittoniya [83]

The correct matches are:

1. Sea level (0 m) - 100%

2. Mid-level elevation (4,500 m) - 57%

3. Peak (8,850 m) - 33%

The level of oxygen in the atmosphere depends a lot on the elevation. The smaller the elevation, the higher the oxygen level, and vice versa, the higher the elevation, the lower the oxygen level. So we have a situation in which the oxygen level is the highest at 0 elevation, or rather at sea level. As we go to higher elevations, let say to around 4,500 m, the oxygen level is significantly dropped, which makes it difficult for breathing. If we go even on higher elevation, like 8,850 m, than the oxygen level will much lower, and a human will need to undergo intense long training and also carry oxygen with him/her in order to survive.

An undersupply of the major inhibitory neurotransmitter known as ________ is linked to seizures.
bazaltina [42]

Answer:

Gamma-aminobutyric acid (GABA)

Explanation:

Epileptic seizures are induced by a preponderance of electrical activity within the network of neurons in the brain. Synapsis is the meeting point between the axon of one neuron and the dendrite of another neuron. Electrical signals don't cross through the synapsis, instead, they are conveyed in a chemical form by neurotransmitters.

The neurotransmitters convey messages across the synapsis in a chemical form until they find to the receptor of the dendrite of the receiving neuron. Neurotransmitters can either be excitatory or inhibitory in function i.e. the receiving neuron can either be stimulated to action or inhibited from action. The main excitatory and inhibitory neurotransmitters in the brain are Glutamate and Gamma-aminobutyric acid (GABA) respectively.

There must be a balance between excitation and inhibition of neurons, in order to ascertain the optimal functioning of the brain. Too much Glutamate or too little of GABA can make neurons hyperexcitable and hyperexcitability of neurons makes the brain susceptible to seizures.

8. Aubrey Kingsley was trapped in a house fire and suffered third-degree burns on her arms, legs.
Luda [366]

Answer:

Third-degree burns destroy the epidermis and dermis. They may go into the innermost layer of skin, the subcutaneous tissue. The burn site may look white or blackened and charred.

Explanation:

The treatment of third-degree burns may require the process of skin grafting or the use of synthetic skin. Severe burns covering large parts of the body may need more intensive treatments such as intravenous (IV) antibiotics to prevent infection or IV fluids to replace fluids lost when skin was burned.
