A paragraph on how selective breeding is better than cloning plz 100 POINTS
harkovskaia [24]

Answer:

Selective breeding is used to promote the benefits of both animal and plant breeding inheritance. It is essentially done by controlled breeding. However, it has its own set of disadvantages, like any other agricultural method-although it is supposed to offer benefits to society. If you want to selectively breed your crops and cattle, weigh them down and decide whether that’s a good way for you.

No company patent is required.Anyone working in farming can start breeding selectively whenever they want. It is a way for him to create more profits every year, as he can grow animals and plants with different characteristics such that they can be generated over centuries, which is good for businesses. And since he is free, he only needs to be knowledgeable and well equipped in the process to achieve the best result.

It makes higher profit possible.Selective breeding encourages more beneficial plant and animal characteristics for farmers. If they have selectively bred cows, for example, these animals can produce more milk than the typical cows and the gene can be transferred to their descendants. If the method is used on crops, more than the typical ones will also be grown. Promoting these advantages will certainly increase their product’s market value. Selective breeding is certainly an perfect choice for farmers who are in a major company.

What is an example of a biotic factor in a biome?: * A. scavengers B. producers C. soil
charle [14.2K]

Answer:

The correct answer is A. scavengers and B. producers

Explanation:

Two types of factors are found in a biome biotic and abiotic factor. All the living things in any biome comes under biotic factors like animals, plants, and microbes and all the non-living things present in the biome are non-biotic factors for example soil, temperature, air, water, salt, etc.

So biome is made up of both living and non-living factors. Scavengers are the organisms that feed on dead and decaying matter and producers are the organisms that make their own food. Most of the producers are plants.  

So both scavengers and producers are living organisms therefore both are examples of biotic factors.
