PLEASE HURRY!! Mendel decided to use pea plants to study for all EXCEPT which of the following reasons?
A. Pea plants grow slowly and have very few offspring
B. Pea plants reproduce $exually because they have male and female parts.
C. Peas plants have several contrasting characteristics, like height, color, and pea pod shape.
Mendel gave the principles of inheritance and used pea plants for his experiment. Pea plants grow slowly and have very few offspring is not the reason for choosing them for the experiment. Thus, option A is correct.
What is the use of the pea plant in genetics?Mendel used the pea plant for experiments of genetics to show the passing of the traits and characters. He used pea plants as they reproduced sexually and had male and female parts.
They also had contrasting characteristics like the color, height and shape of the pea pods, etc. Also, the pea plant reproduced easily with many offsprings.
Therefore, pea plants grow slowly and have very few offspring is not the correct reason.

Landfill waste results in air pollution as _______. a. garbage decomposes and releases methane b. radon trapped in garbage is released c. paint and hairspray cans break down d. vandals set fire to flammable waste please select the best answer from the choices provided a b c d
Answer: Your correct answer is indeed A. garbage decomposes and releases methane.
Hope this helps!
Landfill waste results in air pollution as garbage decomposes and releases methane. Hence option A is correct.
What are Landfills?Landfills are designed to bury and contain waste, but over time, the waste decomposes and produces gases, including methane. Methane is a potent greenhouse gas that contributes to climate change.
It is produced by bacteria that break down organic matter in the waste. As the bacteria consume the organic matter, they release methane and other gases into the air.
To prevent the release of methane and other gases from landfills, modern landfills are designed with systems to capture and control the gases. These systems can include vents and pipes that allow the gases to be collected and either burned off or used to generate electricity.
By capturing and controlling these gases, landfills can reduce their impact on air quality and climate change.
Hence option A, garbage decomposes and releases methane is correct.

Organic Analysis Discussion
Your day in the Forensic Lab had been fairly routine. Around 1:00pm, an investigator drops off some items of evidence to be analyzed from the scene of a homicide. One is a brown gummy substance found at the crime scene, another is an ink pen and note with writing, and the final is an unknown white powder. With each question, your substantial post should have at minimum 5 to 6 sentences for each question and for each of the different pieces of evidence.
For each item of evidence discuss the following:
1) Which analytical method/equipment would you use?
2) Why would you use this particular method for that piece of evidence?
3) How does that method/equipment work? Give details about how the method works.
PLEASE HELP ME
Answer:
1) The brown gummy would be going through a Food & Beverage. The ink pen and note would be going through Chromatography. The white powder would be going through Qualitative analysis.
2) The gummy would be tested for food safety, nutrition, and quality. The ink pen would be tested for separating a mixture of chemical substances into its individual components. The white powder would be tested for a reaction.
3) The method would work for the brown gummy to see why it's brown, how long has it been sitting out, and is there any connection to the case. The method would work for the ink pen and note so it can be thoroughly analyzed to see if it was written in a distressing or frightening matter. The method for white powder would work to determine if it's narcotics or just baking powder.

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.
