Answer:
the number of protons increases.
Explanation:
The answer is 0.47 or 47%.
Let's first distinguish some terms and their frequencies.
R - the dominant allele that causes red eyes
r - the recessive allele that causes green eyes
Since R is dominant over r, lizards with at least one dominant R allele will have red eyes. Therefore, the genotypes and the phenotypes are as following:
genotypes - phenotypes
RR - the lizards with red eyes
Rr - the lizards with red eyes
rr - the lizards with green eyes
Now, we will use some Hardy-Weinberg equations:
p + q = 1
p² + 2pq + q² = 1
where:
p - the frequency of dominant allele R
q - the frequency of recessive allele r
p² - the frequency of lizards with genotype RR
2pq - the frequency of lizards with genotype Rr
q² - the frequency of lizards with genotype <span>rr
</span>
We are interested in <span>the frequency p of the dominant R allele.
</span>So, we have the frequency (72%) of the lizards that have red eyes. However, lizards with genotypes RR and Rr will have red eyes. Since their frequencies are p² and 2pq, respectively, we have:
p² and 2pq = 72% = 72/100 = 0.72
Now, use this in the equation p² + 2pq + q² = 1:
0.72 + q² = 1
q² = 1 - 0.72 = 0.28
From here, we will calculate q and later p using the formula p + q = 1:
q² = 0.28
q = √0.28 = 0.53
p + q = 1
p + 0.53 = 1
p = 1 - 0.53
p = 0.47
Answer:
Photosynthesis stems from plants, so I believe the highest level of photosynthesis would be in dense levels of greenery like maybe parks or national forests. ( sorry if its not specific enough )

Answer:
Polymerase chain reaction (PCR)
Explanation:
Polymerase chain reaction (PCR) is a method by which a target DNA fragment is amplified to produce millions of copies. In PCR, the Taq polymerase enzyme uses nucleotides and primers to replicate a small DNA segment <em>in vitro</em> and produces two DNA molecules. The newly formed DNA molecules are denatured by heating to facilitate their replication to produce four double-stranded DNA molecules. In this way, the number of DNA molecules is doubled in each cycle. Therefore, the small amount of DNA obtained from the minuscule spot of blood on a murder suspect’s shirt can be amplified using PCR.
D. animals supply co2 to plants and plants supply o2 to animals :)
