How does a volcanic eruption affect the Earth's atmosphere?

Luden [163]

Answer:

The gases and dust particles thrown into the atmosphere during volcanic eruptions have influences on climate. Most of the particles spewed from volcanoes cool the planet by shading incoming solar radiation. The cooling effect can last for months to years depending on the characteristics of the eruption. Volcanoes have also caused global warming over millions of years during times in Earth’s history when extreme amounts of volcanism occurred, releasing greenhouse gases into the atmosphere.

9. In guinea pigs, rough coat is dominant (R) to smooth coat (r) and black coat (B) is dominant to white coat (b). A rough black

lisabon 2012 [21]

Answer:

the genotype of the parent guinea pigs are as follows:

RrBb (rough, black) and Rrbb (rough, white)

Explanation:

Since the phenotype of smooth coat is present in the offspring, the parent genotype cannot have RR alleles for their coat. Similarly, the rough, black parent cannot have BB alleles in its genotype because that will not yield a white coat color in its offspring.

After making the dihybdrid cross, the probability obtained for each phenotype is given below:

rough black: $\frac{3}{8}$
