Hweezy Reasoning

What this data is telling me is that there are 1000 individuals in this given population. At the begging of the problem I am told that .731 is the value of q2, which are the homozygous recessive individuals. After that, I solve for q, then p, and then p2; which tells me the value of homozygous dominant inviduals
(.0225).  Once I have the p,q, q2, and p2 values, finding the 2pq value is simple. What I have to do is multiple p times q and then multiply that product by 2. When I do this. I get that the value of 2pq (heterozygous individuals) is .255. However these values are frequencies, so you take each one, multiply it by 1000 and that tells me the number of individuals for each of the groups above. Therefore, there are
255 heterogeneous individuals,
731 homogeneous recessive
individuals and about 23 [when rounded] homogeneous dominant 
individuals.

Step 1: Identify your given values.

·  Population: 1000

·  q2: .731

Step 2: Take the square root of q2 in order to solve for q.

·  √q2 = q

·  √.731 = .85

Step 3: Since the Hardy-Weinberg rule says that the sum of p and q is 1, then to find the value of p,
subtract q from 1. After that, you
square the p value to find the p2 value.

·  1-q=p

·  1-.85=.15

·  p2=.0225

Step 4: Once you have the p,q, q2, and p2 values, finding the 2pq value 
is simple. What you have to do is multiple p times q and them multiply that product by 2.

(p x q)(2) = 2pq
(.15 x .85)(2) = .255

Step 5: To find the number of  individuals in the population, you multiply each  of the values which stand for an individual (p2, q2, 2pq) bythe total number of individuals in the population.

(.255)(1000) = 255 heterogeneous individuals

(.731)(1000) = 731 homogeneous recessive individuals

(.0225)(1000) = about 23 [when rounded] homogeneous dominant individuals.

California Black Worm Lab

The purpose of this lab was to identify the substance (water, depressant, or stimulant) that was added to each of the separate containers of California Black Worms by observing the heart beat of a worm from each container.

To determine which of the different solutions (A,B,C) was which I applied my new knowledge from statistics. With the data we collected in class on Friday, I created three different
stemplots for substance A, B and C.

When I did that, I found that A had the highest values for number in the tens (eg. 11, 12 ...). This led me to conclude that Substance A was the depressant since the heart beat counts were so low.

When I created the stemplots for substances B and C, I found that they both had the highest values for numbers in the twenties (eg. 21, 22 ...). From here I concluded that substance C was the stimulant because it had more values in the 30s than substance be did. I also based my conclusion on my observations during the lab. When I was counting the heart beats of the worms in substance C I can remember that before I was able to get the worms out they were all almost fighting each other and all  intertwined into a ball.

Therefore, this means that substance B is the water, because during the lab I also observed that these worms seemed to just swim calmly.

A Flower, #33

 Finding flowers is easy, but I

wanted to capture something that is different. I had a really great time finding this flower and taking a picture next to it because I did it on the UCLA campus. It was so beautiful and therefore, I wanted to capture a flower that would also reflect the campus' many fascinating  sites. 

A Non-flying Insect, #3

This photo was also taken on the splendid UCLA campus, and might I add that looking for ants was not as easy as I thought it would be. However, I had a great time looking for ants because I was all over the place, I was very determined. Eventually, I found this swarm of ants and I was very hasteful to get my picture taken because they were moving quickly.

This picture was also taken on the
UCLA campus, and I had a good
time finding this item because
it was not easy. I thought to myself
 how I would do this until I found a
whole section of grass by the UCLA
Library filled with snails. That
 happened because all the lawns
had just been watered. The snails
that I have pictures of are the only
ones I could access because I didn't
want to risk crushing several snail
in the attempt of taking a selfie. This
was also fun because the snails were
so slow, and that made it easy to take
the (part) population photo above.
