The correct answer is option C

Index fossil can be defined as the as the reference for the determination of the absolute age of the other fossils.

The age of index fossil can be determined by the radioactive dating or another method by which the absolute age of the index fossil can be determined.

Its age was used as reference to find the age of other fossils.

How was genetic engineering able to solve the problem of tomatoes being damaged in transit without sacrificing taste?
igor_vitrenko [27]

Answer:

The genetic engineering produced on these tomatoes was the solution to reduce the amount of chemical usage to crops as well as introducing a greater disease resistance, insect resistance, and increase shelf life. Conclusively, scientists and farmers still wanted to keep their natural color and flavor, yet change it into a more positive way. 70 years ago, spoke of the dangers of nightshade foods, covering all this ground, and stating that traditionally in South America, where potatoes and tomatoes come from they were eaten as medicine – that is given specifically for a short period time for a specific condition.

Mafic lava tends to have low silica content. Based on this, which of the following statements about mafic lava is most likely tr
sashaice [31]

Answer:

A. It contains fewer volatile gases.

Explanation:

Mafic lava have a composition of about 45-55% silica with high amount of Fe, Mg, Ca.

The silica content is quite low compared to those of granitic magma whose silica content can reach up to about 60%.

What determines the viscosity of magma is basically the silica content of the magma and the temperature of the magma. Viscosity is the resistance to flow.

The higher the silica content, the lower the viscosity and the higher the amount of volatile gases. Such type of magma is the granitic magma. Granitic magma due to their viscosity flows slowly.

The lower the silica content, the higher the viscosity and the lesser the presence of volatile gases in them. Such an example is Mafic magma. Mafic magma flows very slowly with low amount of dissolved gases.

Maru [420]

Answer:

The correct answer is - d.  gradualism.

Explanation:

Gradualism is a model of evolution that explains that the smaller variation in an individual organism that is occurring over a period of the time is to the betterment of the organism in their environment.

These changes or variations allow them to thrive and survive with a slow successive change in an evolutionary line or the whole population. It is a consistent process.

Thus, the correct answer is - D. gradualism.
