100 POINTS! A hypothetical population of 10,000 humans has 6840 individuals with the blood type AA, 2860 individuals with blood

type AB, and 300 individuals with a blood type BB.
What is the frequency of each genotype in this population?

What does the frequency of the A allele?
What is the frequency of the B allele?
If the next generation contain 25,000 individuals, how many individuals would have blood type BB, assuming the population is in Hardy-Weinberg equilibrium?

Here's what we know:
10,000 individuals
6,840 individuals have blood type AA
2,860 individuals have blood type AB
300 individuals have blood type BB

AA genotype frequency: 68.4%
AB genotype frequency: 28.6%
BB genotype frequency: 3%

The A allele occurs 6,840 * 2 + 2,860 * 1 = <span>16,540 times, which is a frequency of 82.7%, meaning the B allele occurs 3,460 times, which is a frequency of 17.3%. In the next generation, 3%, or 750, individuals would have blood type BB.</span>

The Hardy - Weinberg equations are meant to connect a statistical model to primarily Biological characteristics. This is a classic example of how these equations should be used.

This equilibrium has 5 conditions that must be obeyed. Two of the most important are that your sample must be a closed sample which means that no new members are let into the tested group, and none of the group can leave. The second condition is that in order to declare equilibrium the second sample taken must confirm the first. So this is very theoretical.

Equations
A + b = 1
A^2 + 2Ab + b^2 = 1

Method
The examples given always start with the recessive characteristics. In this case, there were 300 out of 10000 that were bb. So you have to figure out that if bb = 300/10000 what does b equal.

b^2 = 300/10000 = 0.03
b = sqrt(0.03)
b = 0.1732 

From this result, using A + b = 1 you get that
A = 1 - b
A = 1 - 0.1732 
A = 0.8268

Finding AA and Ab
A = 0.8268
A*A = 0.8268^2 
AA = 0.6836

Ab = 0.8268 * 0.1732
Ab = 0.1432
2Ab = 2*0.1432
2Ab = 0.2864

Confirming Hardy Weinberg
If the sample has 10000 members total, then 
AA = 0.6836 * 10000 = 6836 members.
2Ab = 0.2868 * 10000 = 2868
bb = 0.03 * 10000 = 300
The total is 10000 as expected.

Do these results follow the second Hardy Weinberg Equation
AA + 2Ab + bb = 0.6836 + 0.2868 + 0.03
AA + 2Ab + bb = 1.0004 which can be explained as a rounding error. 
 
If the sample next year is 25000, what should the results be?
The sample states that in the second year, the sample size is 25000. Equilibrium will be established if the 25000 is calculated with the same ratios.

AA = 0.6836 * 25000 = 17090
2Ab = 0.2868 * 25000 = 7170
bb = 0.03 * 25000 = 750

Confirmation
17090 + 7170 + 750 = 25010 which again can be a rounding error.
Note: you can get a confirmation by just multiplying the numbers you got for 10000 by 2.5
For example bb = 2.5 * 300 = 750
For 2Ab = 2868 * 2.5 = 7170
I'll leave AA to you

Mental processes such as thought, language, memory, and speech are processed in the ______ areas of the cerebral cortex.
xxMikexx [17]

Answer:

Frontal lobe

Explanation:

They areas of the cerebral cortex is divided into major four compartments.

  • The frontal lobe
  • The temporal lobe
  • The parietal lobe
  • The occipital lobe

The frontal lobe is situated at the anterior part of the brain whose main function is required in handling of mental processes such as thought, language, memory and speech. With the aid of the frontal lobe, we are able to think, communicate and process information.

The temporal lobe which is located beneath the frontal,parietal and occipital lobe helps to fine tune sounds and plays an integral role in hearing.

The parietal lobe is found at the back of the frontal lobe and also just above the temporal lobe helps to maintain body balance and trigger the body in cases of alertness.

The occipital lobe is located at the posterior region of the brain whose main function is reserved for visual perception.

Crop monitoring makes use of space-based data to keep tabs on crop development and forecast crop yields for certain fields that have been planted.

<h3>What is monitoring systems?</h3>

A system for monitoring agriculture consists of a network with wireless sensors. These sensors gather information from several nodes positioned on the playing surface. Then, specialists or nearby farmers analyze this data. The data can be used to make a number of inferences about weather patterns, soil fertility, crop quality, etc. A system is developed for agricultural field monitoring in IoT-based modern agriculture with the aid of sensor like light, humid, temperatures, soil moisture, etc. Farmers may monitor the condition of thier fields from any location. IoT-based smart farming is considerably more efficient than conventional farming.

<h3>How do farmers monitor their crops?</h3>

Nowadays, satellite techniques are widely employed in agriculture, and many farmers use them frequently to observe their fields and assess the condition of their crops. Crop monitoring is crucial for managing various pests, weeds, and diseases that affect crops. This gives information about the crop's current situation, and you can then look ahead in time to forecast what will probably be the crop's next problem.
