Answer:
A. 4 right handed coil:0, left- handed coil
Explanation:
According to MENDELION CROSS:
We will get NN, Nn,Nn,nn
NN, Nn, Nn are the 3 right handed coiling and nn is left handed coiling.
But in case of shell coiling in snails, maternal inheritance is applied in which offspring is decided only by phenotype.
Maternal traits: Here,female parent has right handed shell coiling. so, all the offsprings will have the same.
Hence, the phenotypic ratio will be:
4 Right handed coil: 0 Left handed coil

<u>Answer:</u>
<em>The dissolved gases produce violent eruption as they escape.
</em>
<u>Explanation:</u>
Magma contains dissolved gases and these dissolved gases induce vapor <em>pressure on the magma.</em> The magma is able to remain in the dissolved state itself without erupting because this vapor pressure is less than the confining pressure of the <em>rock surrounding the magma. </em>
One the vapor pressure exceeds this confining pressure the dissolved gases begin to expand and<em> forms small gas bubbles</em>.
The <em>density of these gas bubbles</em> called vesicles is less than the density of magma and thus naturally tries to push out. When the gas bubbles escape the magma is also pushed out. Thus greater <em>amount of dissolved gases result in violent eruptions.

Hippos likely evolved from a group of anthracotheres about 15 million years ago, the first whales evolved over 50 million years ago, and the ancestor of both these groups was terrestrial. These first whales, such as Pakicetus, were typical land animals. They had long skulls and large carnivorous teeth. Hope I’ve helped ;)
