The stem holds plants up.
Answer:
It is not possible because AB blood type will always be more dominant and if you make a punnett square you can see this. The blood type will more like be an A or B because those are the dominant alleles.
Answer:
Circadian disruption may increase our risk of obesity, diabetes, mood disorders, reproductive problems and cancers. Numerous studies have linked working the night shift and exposure to light at night to increased risks for breast and prostate cancers and other health problems.
Explanation:
Working at night time shift can sometimes cause he/she to fall asleep
The answer is <span>A. p2 = 0.36, 2pq = 0.48, q2 = 0.16.
</span>
Let's first distinguish alleles frequencies from genotypes frequencies:
p - a frequency of R allele,
q - a frequency of r allele,
p² - a frequency of RR genotype,
2pq - a frequency of Rr genotype,
q² - a frequency of rr genotype.
<span>The gene frequency of allele r changes from 0.38 to 0.40, thus:
</span>q = 0.40
Now, we will implement this in the following equation:
p + q = 1
If q = 0.40, then:
p + 0.40 = 1
⇒ p = 1 - 0.40
⇒ p = 0.60
Now, the frequencies of both alleles are know and it is easy to calculate the <span>genotype frequencies:
-</span> the frequency of RR genotype: p² = 0.60² = 0.36
- the frequency of Rr genotype: 2pq = 2 · 0.60 · 0.40 = 0.48
- the frequency of rr genotype: q² = 0.40² = 0.16
Therefore, the new genotype frequencies in that population are <span>p2 = 0.36, 2pq = 0.48, q2 = 0.16.</span>
The closing of a plants stomata will prevent plants from taking in (Carbon dioxide) or co2; Without co2, plants cannot make carbohydrates, and plants can only obtain this critical molecule (carbohydrates) when stomata are open. Hope this helps ya out :)
