The founder effect: is the reduction in genetic variation that occurs when a small subset of a large population is used to establish a new colony. The new population can be very different from the original population, both in their genotypes and in their phenotypes.

Suggest one advantage that electrophoresis has over chromatography.A. Electrophoresis separates molecules based on differences i
Arisa [49]

Answer:

B. Electrophoresis separates molecules based on charge differences, thereby making it possible to separate molecules that are similar in size, shape, and density.

Explanation:

Chromatography is a process that is used for the separation of complex mixtures of molecules by many repeated partitioning between a flowing (mobile) phase and a stationary phase. The process exploits the properties of the molecules such as charge, size, binding affinity, etc.  

However, gel electrophoresis is the technique that separates the molecules based on their charge or mass. It can separate a mixture of molecules with a similar charge based on their mass. Likewise, if all the molecules of a mixture have the same mass but differ in charge, gel electrophoresis can be used to separate them based on their different charges.  

For example, a mixture of proteins is allowed to run through the gel of cross-linked polymer polyacrylamide under electrical potential towards the positive or negative electrode. The polyacrylamide gel serves as a sieve and allows the proteins to migrate in proportion to the charge to mass ratio. If all the proteins are of the same mass, gel electrophoresis would separate them based on their charge.

Discuss how heat stroke, acquired during extreme physical exercise, disrupts the feedback loop and the impact this disruption ha
Vera_Pavlovna [14]

Answer:

Heat stroke is acquired during extreme physical exercise when the environment is hot, strenuous activity, excess clothing and tight clothing, drinking alcohol and smoking during a hot season or environment,when you are dydrated and not drinking water. Some medication and age also add to having heat stroke.

It causes disrupts in the feedback loop because it doesn't form a circular chain. It can be both positive and negative chain. Feed back loop is known to be either negative or positive channel or pathway formed by an effects.

The impact and disruption it has on human physiology

1.it causes brain damage

2.it leads to death

3.it also causes vital organ damage

Explanation:when the environment is hot, it makes you heat up fast when exercising and increase your temperature because the atmospheric temperature is high,and when exercising in this condition without air conditioner to cool your surroundings it leads to heat stroke.

When wearing heaving clothing and tight clothing during physical exercise it makes you to not lose moisture and makes air not easily passed to you, this causes your body to heat up fast and thereby causing heat stroke.

When dydrated and not drinking water causes you to overwork you body and not cool it down, it leads to heat stroke.

Heat stroke causes brain damage, leads to death when not taken immediately or rush to the health center or hospital.

which part of the brain is represented by the highlighted area shown below? cerebrum cerebellum medulla oblongata pons
Leviafan [203]
Cerebrum is in the most anterior part of our brain, fronting of the skull. It functions in sensory and neural processes. Cerebellum is found at the back of the skull. It functions in coordination, balance and muscular activity. Medulla oblongata connects from the spinal cord which controls heart and lungs. Pons is part of the brainstem which controls breathing and communication.
