What are the advantages and disadvantages of genetically modified organisms?

Kazeer [188]

Answer: Advantages: better crop yield, healthier plants and animals, and more appealing food. Disadvantages: potential health issues, lower quality of life for animals, ecological disruption.

Explanation:

(This answer includes and focuses on the process of artificial selection as genetic modification)

Advantages

Better crop yield: genetic modification is commonly used in agriculture to select plants with better yields, allowing future plant generations to grow more and produce more.

Healthier plants and animals: plants and animals can be bred or otherwise modified to increase their disease resistance or to eliminate health issues found in earlier generations.

More appealing food: farmers can breed the plants with the best-tasting fruits to create an overall more appealing fruit. Scientists have also used direct genetic modification through genome editing to create new types of apples and other fruits.

Disadvantages

Potential health issues: most easily understood with dog breeds, which have been artificially selected and bred to have specific characteristics. This leads to some breeds being more susceptible to various health issues, namely respiratory disruption in those with flattened faces.

Lower quality of life for animals: seen in poultry farming, where chickens and other birds have been modified to be as big as possible. While this does provide a higher meat yield, it also causes the birds to live for an extremely short amount of time, most of which is spent being unable to move.

Ecological disruption: in the attempt to prevent insects from feeding on plants through genetic modification, the insect populations can be harmed by a lack of food sources. This can lead to other disruptions up the food chain, that, while typically minor, could eventually have larger consequences.

Describe how your peripheral nervous system and your central nervous system were involved in a simple activity your performed to

Musya8 [376]

Your peripheral nervous system includes the bunch of nerves outside your brain and nerves outside your spinal cord. Your central nervous system includes your actual spinal cord and brain.

One thing you could have done is sat down to breakfast. Your peripheral nervous system sent the information about what you smelled to your brain, and also sent nerves impulses to your brain to bend your legs. Your brain, which is in the central nervous system, can distinguish different smells.

Which of the following is a radical? O OH H 2 O H

Olegator [25]

The radical in this question is OH.

The reason this will be a radical, is that the definition of a radical is the presence of an unpaired electron. This causes the radical to be unstable, desperately wanting to do something with the free electron that it has.

Oxygen has a charge of 2-, and Hydrogen has a charge of +1. When you pair them, you end up with a net charge of 1-, which is the presence of that unpaired electron. It will usually be written as: $OH^{-}$

The volume of a certain gas is 29.3 liters at STP. What would be the volume of the same gas at 1.39 atmospheres and -23.00C? (R=

Andrew [12]

Answer:

19.32L

Explanation:

Given parameters:

Volume of the gas at STP = 29.3liters;

Using this information first, let us find the number of moles of the gas.

Number of moles = $\frac{volume of gas}{22.4}$

With the number of moles, we can further solve this problem;

Number of moles = $\frac{29.3}{22.4}$ = 1.31 moles

More parameters;

Pressure on gas = 1.39atm

temperature = -23°C = -23 + 273 = 250K

Unknown:

Volume of gas = ?

Solution:

The ideal gas equation is the perfect fix to solve this problem.

It is mathematically expressed as;

Pv = nRT

where P is the pressure

v is the volume

R is the gas constant

n is the number of moles

T is the temperature

Input the parameters;

1.39 x V = 1.31 x 0.082 x 250

V = 19.32L
