Choose one of the following scenarios and answer the questions provided. Support your answers using scientific reasoning and discussing possible impacts to individuals, society, and the environment. Be sure to also discuss any medical or ethical issues that may apply.

Scenario 1:

Scientists have developed genetically engineered plants that are pest-resistant. By adding genes to the plant's DNA, they become toxic to insects (but not to plants or animals). This means that these plants may not need to be sprayed with pesticides to ward off the insects.

Would you be willing to eat these genetically altered crops? Explain your answer. (5 points)

What are some possible impacts (positive or negative) of this genetically engineered plant on the environment, society, and individuals? (5 points)

Answer:

9600 cm/min

Explanation:

Well, the circumference of the flywheel is 2π×the radius(16 cm). That's how far the spot moves in one revolution.

10 radians per second divided by 2π is the number of revolutions per second.

So multiply that times the circumference and that's the distance the point has traveled.

let the linear speed of the spot be v

v= \frac{10}{2\pi}\times2\pi\times16= 160cm/sec

therefore, v= 160×60= 9600 cm/min

What is a phenotype?
Papessa [141]

Answer:

a. the result of an individual's genetic constitution

Explanation:

Phenotype is the morphological expression of genotype. The genetic constituent of an individual is known as genotype. Genotype determines the genetic traits and imparts specific features of the organisms which constitute the phenotype of the organism.

The phenotype of the organisms depends on the type of the alleles of the genes present in the genome of the organisms.

For example, a human with genotype "ii" has blood type "O". Here, "ii" is the genotype that is responsible for phenotype "O blood type".

On the other hand, a human with genotype "IAIA" has blood type "A". Here. "blood type A" is the phenotype.

When neurons "fire," the first thing that happens is that sodium ions enter the cell. this does not require an input of energy.
Karo-lina-s [1.5K]

Answer;

One can infer that membrane transport proteins are required in order for neurons to fire.

Explanation;

Transport proteins are proteins that transport substances across biological membranes. Transport proteins are found within the membrane itself, where they form a channel, or a carrying mechanism, to allow their substrate to pass from one side to the other.

-Transport proteins transport materials such as; ions such as sodium and potassium; sugars such as glucose; proteins and messenger molecules; and many more. In neurons, they  play a fundamental role in the functioning of nerve cells. These transporters, a third class of membrane transport proteins, move a wide variety of ions and molecules across cell membranes.

How did fossil<br> fuels form, and how<br> are they obtained<br> and used?
Usimov [2.4K]

Explanation:

Fossil fuels are important energy sources for our every day activities.

  Formation of fossil fuels

Fossil fuels forms from the accumulation and burial of organisms in a basin of deposition. Instead of the organisms decaying, they preserve their carbon content. To be worthy of becoming fossil fuels, organisms must be buried in an environment where there is little to no oxygen to fast-track decomposition of the buried organic matter. Increase in temperature and pressure causes the organic matter to transform into fossil fuels.

How are they obtained

First, different fossil fuels have their extraction techniques because they occur in different physical state of matter.

For the solids e.g coal: exploration is carried out first and if a prospect is delineated, mining engineers design the best way to extract the coal from nature. Coal is usually found laid in sedimentary beds in nature. Top layers of sediments can be removed to extract the coal.

For fluids such as crude oil and natural gas, after a prospect is identified, a rig is usually constructed to extract the fluid and gas. The natural pressure allows for the fluids the rise within the drill used in extraction.

How are they used

Coal and gas are used to power electrical generating plants. They are used to heat steams which drives turbines and produce electricity.

Natural gas is used as a domestic fuel for cooking and so also coal.

When crude is processed a lot of product is obtained. Gasoline is used to power most internal combustion engines. Some chemicals useful for manufacturing plastics, drugs e.t.c are also derived from the processed crude.
