What question are you talking about ?
Answer:
frog
Explanation:
frogs live their first part of their lives in water so they need gills but after metamorphosis they live on land so they need lungs.
The answer is 0.43
To calculate p we will use one of two formulas of the <span>Hardy-Weinberg principle:
</span>
p² + 2pq + q² = 1 and p + q = 1
where:
p - the frequency of the allele for long legs which is a dominant trait.
q - the frequency of the allele for short legs which is a recessive trait.
p² - the frequency of dominant homozygote (with long legs)
2pq - the frequency of heterozygote (with long legs)
q² - the frequency of recessive homozygote (with short legs)
So, 33 of 100 organisms have short legs. The frequency of recessive homozygote is represented by q²:
q² = 33/100 = 0.33
⇒ q = √0.33 = 0.57
Using the formula:
p + q = 1
p = 1 - q = 1 - 0.57 = 0.43
Therefore, p = 0.43
Answer:
C.organisms had adapted to new environments,givingrise to new species
Explanation:
-On his visit to the Galapagos Islands, Charles Darwin discovered several species of finches that varied from island to island, which helped him to develop his theory of natural selection.
-He noticed that each finch species had a different type of beak, depending on the food available on its island. The finches that ate large nuts had strong beaks for breaking the nuts open.
I like to think of the DNA molecule strand as a ladder, rather than a spiral staircase. The siderail of the DNA ladder (The DNA "Backbone") consists of the Sugar and Phosphate molecules. The rungs of the ladder (the inner bases) consist of the pairs of Nitrogen Bases - Adenine, Guanine, Cytosine and Thymine.
hope this helped :)
