explain how genetic engineering of plants and animals can be both beneficial harmful to the environment and to people.
Answer:
Genetic engineering of both plants and animals can cause food to be more abundant and can restore nitrites to soil in the case of plants and animals can create more stable environments by eradicating invasive species, however, there are concerns about improperly modified crops causing cancer in humans, they may overtake the genetically "pure" crops in the area, and animals have the concern of ethics and cancer.
Explanation:
Genetic engineering is generally seen as the future of food. It can serve as a cure for world hunger, causing enough food to be produced in a small enough space to provide for most of the world and causing plants to adapt to inhospitable growing conditions, however, there are concerns. For one, when genetically modifying animals, there may be the concern of how much body mass you can ethically put on an animal before it becomes torturous. You also have to worry about animals genetically processed to produce more meat developing cancerous growths due to their predisposition to gain more mass quickly, however this can be remedied. Animals, on the positive end, can be designed to feed off of invasive, harmful species. Plants may overtake their genetically "pure" cousins, however that is not necessarily a bad thing, as plants are equipped to evolve anyway, and it's quite possible you're just giving the plants a head-start.

The beginning of the Cambrian period marks an important event in animal evolution - the appearance of organisms with ________.
Answer:
The beginning of the Cambrian Period is marked by the evolution of hard body parts such as calcium carbonate shells. These body parts fossilize more easily than soft tissues, and thus the fossil record becomes much more complete after their appearance.

How does shotgun cloning differ from the clone-by-clone method?.
No genetic or physical maps of the genome are needed to begin shotgun cloning and is much faster.
What is Shotgun cloning?
This is a method to duplicate genomic DNA in which it is smashed into small pieces and the fragments are then taken together and cloned into a vector.
This type of cloning however is faster as there are no genetic or physical maps needed to begin the process.

Weather can change, but climate can't.
B
Weather and climate are the exact same thing.
C
Weather describes precipitation; climate describes temperature.
D
Weather is measured from day to day; the climate is the average weather over a long period of time.
Answer:
d
Explanation:
Weather is constantly changing for example it is raining today however, tomorrow it will be sunny and hot. On the contrary, climate is the weather over time. For example, if it is usually hot most days then the climate is hot. If it only hot that day then it is weather, if it was hot for the past 5 months (as an example) then it is climate. Hope this helps.
Answer:
D
Explanation:
Weather is measured from day to day; the climate is the average weather over a long period of time.
