1. Effect: Radiogenic heat released- Cause: convection currents cycle through magma.
2. Effect: Earth has a powerful magnetic field- Cause: Iron in earths outer core swirls due to convection currents.
3. Effect: Tectonic plates move- Cause: unstable isotopes in earth release energy.
What is Convection current?Convection currents are defined as the result of differential heating where lighter, less dense, warmer materials rise while heavier, more dense, cooler materials sink. This is the movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the Earth's mantle.
Convection currents arise from differences in fluid density that arise due to a temperature gradient, resulting from the continuous replacement of the hot fluid in the region of the heat source with the nearby cold fluid which is known as the natural convection currents.
Thus, Radiogenic heat released- Cause: convection currents cycle through magma.

Read the passage. Then explain the ways humans have influenced the traits in corn plants and the impacts each biotechnology has had.
Passage
Many of the types of corn found in grocery stores were originally bred for their taste and productivity. But these varieties are often threatened by pests. This makes it harder for farmers to produce enough corn.
Scientists have used genetic engineering to make GMO corn plants that are resistant to pests. In one type of GMO plant, they added genes from bacteria that live in soil. The genes let the GMO plants produce a bacterial protein that kills certain insects.
Answer:
It decreases cost of production on the crop as well as increase production.
Explanation:
It is a very efficient method to save a corn plant from the attack of bacteria. This method is used in almost each and every plant in order to make it resistance against harmful pests and microorganism. By using this technology, the cost of production on the growing of crop decreases which gives more profit to the farmers as well increase the overall productivity of that corn crop.
Answer:
One of the ways we have influenced the traits in corn is through selective breeding. We now have taller plants, and bigger ears of corn, that taste better. Another way we have influenced the traits is by modifying them to be pest resistant.

Adaptations that result from natural selection are expected to increase
the fitness of an organism. In terms of natural selection, which of the
following best describes fitness?
A Being able to escape from predators
B Being among the strongest organisms in a population
C Being able to survive, find a mate, and produce offspring
D Being able to survive long enough to reach the adult stage
Answer:C Being able to survive, find a mate, and produce offspring
The fitness that should be explained when being able to survive, also find the mate and it generated the offspring. Hence. option c is correct.
What is fitness?It is considered as the health and its well-being. It is the capability for performing that should be based on sports, occupations, and day to day activities.
It is generally accomplished via proper nutrition, physical exercise, proper sleep.
Therefore we can conclude that the option c is correct.
And, the rest of the options are considered to be wrong.

How does gene flow directly contribute to evolution?
Answer:
Evolution can also occur as a result of genes being transferred from one population to another. This gene flow occurs when there is migration. The loss or addition of people can easily change gene pool frequencies even if there are no other evolutionary mechanisms operating.
