This is what it says in my notes for edge 2020

Tim used a chemical control method known as pesticide application.

Pesticide application involves the use of chemicals to control or eradicate pests, such as insects, fungi, and weeds. In Tim's case, he applied a pesticide to the outer layer of his crop stems to control the non-native fungus that had affected his crops. Pesticides can be applied in various forms, such as sprays, dust, and granules.

The type of pesticide used depends on the target pest and the crop being protected. While chemical control methods such as pesticide application can be effective, they also have potential drawbacks, such as the development of pesticide resistance in the targeted pest populations and the risk of harming non-target organisms and the environment.

Explanation:

the question is asking about the energies. when the two cars are moving towards each other they are accelerating meaning they have kinetic energy. when they collide; on rebounding, the car regains a smaller amount of kinetic energy – this time travelling backwards. So the overall process is that kinetic energy becomes heat and spring potential energy, which results in heat, smaller kinetic energy and, hopefully, surviving occupants. so the speed of the car before and after will show the energy change

Explanation: 20% of invasive species are introduced by Shipping so checking the ballast tanks in cargo ships would help the most I think

To reduce introductions of Non-native species, ships should install some form of cleansing mechanisms before releasing their ballast water during transport and also check for unintended cargo.

Non-native species are also called invasive species. They are called so as they are foreign or not indigenous to a particular ecosystem and have been introduced to the said ecosystem by some unnatural methods.

These species show a high capacity for adaptation to their new environment. They quickly multiply and reproduce and therefore increase in population.

This sudden and unnatural increase in their population soon after they are introduced to a new environment will greatly affect the ecosystem of the new environment. The new species will compete with the native organisms of that environment for resources. This may cause the native flora or fauna to become endangered or even extinct.

The accidental introduction of invasive species happens quite often and causes a lot of problems. In a marine ecosystem, it happens a lot due to the ships that travel through a variety of marine regions.

So, ships should install some form of cleansing mechanisms before releasing their ballast water during transport and should be checked for unintended cargo.

Therefore, the correct option is D.

Answer: During crossing over, part of one chromosome is exchanged with another. The result is a hybrid chromosome with a unique pattern of genetic material. Gametes gain the ability to be genetically different from their neighboring gametes after crossing over occurs.

Explanation:

Gregor Mendel explains his trials with peas that demonstrated that heredity is passed down in distinct pieces. People have always noted the likeness , both in animals and plants and in human families.

When Mendel tested purple- and white-flowered pea plants, he discovered that the F1 generation included no white-flowered plants. White-flowered plants were seen in the F2 generation. Choose the correct statement from the list below. The purple-flower gene is dominant over the white-flower allele.

Mendel then crossed these pure-breeding plant lines and noted the characteristics of the hybrid offspring. He discovered that all of the first-generation (F1) hybrids resembled one of the parents.

Explanation:

The evolution of the rock pocket mouse is a great example of how natural selection can lead to the adaptation of a species to its environment. The mutations that occurred on the Mc1r gene allowed some individuals of the population to have a different fur coloration than the rest of the population. This new fur coloration provided a selective advantage to the mice living in the darker volcanic rock environment.

The darker fur of the rock pocket mouse provided camouflage against predators, allowing them to blend in with the dark rocks and avoid being seen. This made them less likely to be preyed upon by predators such as owls and snakes, which hunt by sight. As a result, the mice with the darker fur were more likely to survive and pass on their genes to the next generation.

Over time, as the population of the rock pocket mouse continued to be exposed to predation, the proportion of individuals with the darker fur coloration increased. This is because the individuals with the darker fur coloration were more likely to survive and reproduce, passing on their advantageous traits to their offspring. Eventually, the population became dominated by individuals with the darker fur coloration, and the rock pocket mouse became a distinct species.

This process, in which mutations that provide a selective advantage become more common in a population over time, is known as natural selection. In the case of the rock pocket mouse, the mutations that occurred on the Mc1r gene allowed the mice to adapt to their environment and avoid predation, ultimately leading to the evolution of a new species.

Asexually reproducing aliens would be more susceptible to the NASA-created virus. Option A is correct.

This is due to the fact that asexual reproduction creates genetically identical offspring through the process of mitosis without the transfer of genetic material from one person to another. Because of this lack of genetic diversity, any mutation or genetic change caused by the virus would have an impact on the entire population. On the other hand, through meiosis and fertilisation, sexually reproducing aliens create offspring with distinctive genetic material. Due to the fact that different people would react to the virus differently due to genetic diversity, it would be more challenging for the virus to infect the entire population. As a result, the virus would spread more readily and have a greater effect on the asexually reproducing aliens.

The clownfish's reproductive strategy of laying eggs near a sea anemone is a form of protection and survival for its offspring.

By laying their eggs in close proximity to the sea anemone, the clownfish provide their eggs with a safe place to develop. The sea anemone's tentacles are a powerful defense mechanism that can fend off potential predators that may try to harm or eat the eggs.

In addition to protection, the clownfish also benefit from the relationship with the sea anemone during the reproductive process. The anemone provides a clean surface on which the eggs can be attached and also helps to oxygenate the surrounding water, which is important for the development of the eggs.

The anemone's tentacles also help to keep the eggs free of harmful parasites and fungi. Overall, the clownfish's reproductive strategy of laying eggs near a sea anemone is a mutually beneficial relationship that helps to ensure the survival of the clownfish offspring.

The protection and benefits provided by the sea anemone help to increase the chances of the eggs hatching successfully, resulting in a higher survival rate for the next generation of clownfish.

The ecology suffers greatly from livestock farming. It is the main cause of biodiversity loss, habitat damage, and water pollution, contributing to half of the world's greenhouse gas emissions.

Chemical fertilizers, herbicides, and insecticides of various kinds are used in intensive farming. Animals are housed in holding facilities, which can result in overpopulation, pollution, and the spread of diseases and infections.

Both land and carbon are used up while raising animals for food. Farm animals such as cows, chickens, and pigs emit enormous volumes of methane gas and need pastures, both of which are at risk as a result of desertification and soil erosion as global temperatures rise.
