prisoha [69]

To calculate the frequency of the heterozygote genotype (Pq) for this gene we must use the Hardy-Weinberg equation ( p2 + 2pq + q2 = 1 ). This equation relies on the Hardy-Weinberg principle, a model in population genetics that states that the frequency of the alleles in a population is never changing, only the combinations (the genotypes) are changing.

If there are only two alleles (variations) of this gene in a population, then their frequencies should add up to 1 (100%). From this, we can calculate the frequency of the q allele.

p +q=1

0,3 +q=1

q= 1-0,3

q= 0,7

Now hat we have the frequency of the q allele we can use the HW equation to calculate the frequency of the heterozygotes.

p^{2} + 2pq + q^{2} = 1

(0,3)^{2} + 2pq +(0.7)^{2} = 1

0,09 + 2pq +0.49= 1

2pq +0,58= 1

2pq= 1-0.58

2pq=0,42

The freqency of the heterozygotes in this population is 0.42

Essay Frankenstein predictions
atroni [7]

Answer:

The monster in Mary Shelly’s Frankenstein lurches into life as big as a man but as ignorant as a newborn. He can’t read, speak, or understand the rudiments of human interaction. When he stumbles upon the cottagers, however, he picks up language by observing them and studying their speech. It is this acquisition of language, along with the eloquence it brings, that turns the monster from a mysterious nightmare into a sympathetic and tragic figure. By showing how language transforms the monster, and by contrasting the well-spoken monster with his equally articulate creator, Shelley argues that verbal communication—rather than action or appearance—is the only way through which people can truly understand one another.

To disprove spontaneous generation, pasteur used swan-necked flasks to allow entry of air to the boiled broth while blocking con
Andru [333]

Pasteur produced a nutrient broth and placed equal amounts of it in two long necked flasks. One flask had a straight neck (control) and the other had a swan shaped bent neck (being tested). He boiled the broth in both the flasks to kill any living organism that might be surviving on it. The two flasks were then left in the open air of the room to cool down. After several days passed, Pasteur noticed that the broth in the straight necked flask had changed its color but the swan necked flask didn't. From this observation he was able to conclude that the straight necked flask had let the organisms enter the flask and contaminate the broth. The swan necked flask blocked the entry of the organisms from the open air and thus remained unaffected.

aliina [53]

Answer:

The answer is option D "Machines have replaced much of the manual labor once needed to run a farm."

Explanation:

* Progress in Engineering: This simply means how technological machines like heavy tractors which are now used and are helpful in farming are  evolving, meaning they are being used in a larger quantity now.

* Natural Environment: This is the normal way of life or doing things which individuals find themselves practicing in a particular society and at a particular point in time.

* As a result of the machines being developed as an Engineering progress which serves the work of people on the farms, there tends to be less manual labor that would be initially required to run a farm. The machines are now serving the work of human beings (laborers) now.
