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.

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.

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.

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.

Explanation:

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.

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.

The study of magnetic domains is defined as the micro magnetics. The Magnetic domains are outside of a magnet is not true. The correct option is C.

A magnetic domain is defined as a region within a magnetic material in which the magnetization is in a uniform direction. This indicate that the individual magnetic moments of the atoms are aligned with one another and they point in the same direction.

The magnetic domain structure is responsible for the magnetic behavior of ferromagnetic materials like iron, nickel, etc. The domains are found to be oriented randomly if there is no external magnetic field.

Thus the correct option is C.

The role of fungus in the food web shown is to break down organic matter into carbon dioxide and water. The correct option is A.

Fungus is a eukaryotic organism. They grew in soils and wood and moist and dark places. Fungi break down the material. While consuming the nutrients in the decaying matter, they produce enzymes that break down the material.

The biomass would be overrun with the dead matter without the majority of fungi, which is why they are helpful. Bacteria and actinomycetes are some additional decomposers. They act as nature's recycling machine by consuming animal carcasses, bones, dead plants, and various minerals thanks to their enzymes.

Therefore, the correct option is A. To break down organic matter into carbon dioxide and water.
