<span>The factors that turned ferns into fossil fuels over thousand of years are pressure and heat.Ferns live in swamp forests, when they died and decayed they formed layers at the bottom of the swamp. Soil and water will built up and the heat and pressure would cause the decayed ferns to change over thousands of years, continuing to decay in the absence of oxygen will turn the fern into fossil fuels. <span>

Explanation:
If they´re mutated it means that there was a modification in they´re genes, which makes them resistant to any actions that us humans took to prevent the previous generation of influenza viruses.
Answer:
Since there was a change in their genetic code to resist our treatments/ preventions, they pose a higher risk to us. Why? Because our treatments/preventions will be useless and the virus might cause some damage until our solutions to prevent/cure it are updated, that is, if we don´t have to re-invent any.
Tip:
You can think of the influenza virus as a software. The mutation can be an update that gets rid of a bug, which would be our preventions (vaccines).

Answer:
2. G green (female) x white (male)
Explanation:
<em>The cross that could produce progeny plants with green leaves would be the cross between a green female and a white male.</em>
<u>Since the transmission of leaf color in the plant demonstrates organelle inheritance, the female controls which leaf color is inherited by the progeny. Organelles are generally located in the cytoplasm which is largely contributed by the female egg during fertilization. Hence, organelle inheritance are controlled by the female and that is why they are often referred to as maternal inheritance.</u>
Therefore, a cross involving a green female and a white male would largely yield green progeny provided that the trait inheritance follows an organelle inheritance.
