In what ways has genetic engineering been used in agriculture to increase the amount of harvested food?

Insect resistance. This trait provides farmers with season-long protection against target pests, reduces the need for pesticide applications, and lowers input costs.Drought resistance. GM crops that express drought resistance can grow in much drier areas, conserving water and other environmental resources.Herbicide tolerance. Crops that can tolerate specific herbicides allow farmers to fight weeds by applying herbicides only when needed and enable them to use no-till production methods that preserve topsoil, prevent erosion, and reduce carbon emissions.Disease resistance. Through genetic modification, the Hawaiian papaya industry was able to recover from the devastating papaya ring spot virus that had crippled the industry.Increased/enhanced nutritional content. Currently in development are genetically modified soybeans with an enhanced oil profile, much like olive oil, made to be longer lasting and trans fat free.

Which of the following scenarios would most likely be considered pseudoscience?

natali 33 [55]

The belief that the stars determine our fate is considered to be pseudoscience .

Large celestial bodies called stars are mostly made of hydrogen and helium, and in their cores, churning nuclear forges produce light and heat. Except for our sun, all of the other stars in the sky that we can see are light-years from the our planet i.e. earth.
Celestial bodies, also referred to as heavenly bodies, are celestial objects in space, including the sun, moon, planets, and stars. They are a component of the vast universe that we exist in and are normally fairly far away from us.

Pseudoscience, which is defined as an activity that purports to be scientific but is actually not, is defined as seems science. Science does not engage in extraterrestrial affairs it simply studies the natural world. Science cannot provide an answer to morality, immorality, or questions of meaning or purpose, but it does require ethical behavior. In other hand astronomy is regarded as pseudoscience since no link between the locations of the stars and human behavior can be demonstrated using evidence from science.

A long, thin superconducting wire carrying a 17 A current passes through the center of a thin, 3.0-cm-diameter ring. A uniform e

nalin [4]

Answer:

$\frac{dE}{dt} =- 2.72 *10^{15} \ N/C \cdot s$

The direction of the electric field is opposite that of the current

Explanation:

From the question we are told that

The current is $I = 17\ A$

The diameter of the ring is $d = 3.0 \ cm = 0.03 \ m$

Generally the radius is mathematically represented as

$r = \frac{d}{2}$

$r = \frac{0.03}{2}$

$r = 0.015 \ m$

The cross-sectional area is mathematically represented as

$A = \pi r^2$

=> $A = 3.142 * (0.015^2)$

=> $A = 7.07 *10^{-4 } \ m^ 2$

Generally according to ampere -Maxwell equation we have that

$\oint \= B \cdot \= ds = \mu_o I + \epsilon_o \mu _o\frac{ d \phi }{dt }$

Now given that $\= B = 0$ it implies that

$\oint \= B \cdot \= ds = 0$

$\mu_o I + \epsilon_o \mu _o\frac{ d \phi }{dt } = 0$

Where $\epsilon _o$ is the permittivity of free space with value $\epsilon_o = 8.85*10^{-12 } \ m^{-3} \cdot kg^{-1}\cdot s^4 \cdot A^2$

$\mu_o$ is the permeability of free space with value

$\mu_o = 4\pi * 10^{-7} N/A^2$

$\phi$ is magnetic flux which is mathematically represented as

$\phi = E * A$

Where E is the electric field strength

$\mu_o I + \epsilon_o \mu _o \frac{ d [EA] }{dt } = 0$

=> $\frac{dE}{dt} =- \frac{I}{\epsilon_o * A }$

=> $\frac{dE}{dt} =- \frac{17}{8.85*10^{-12} * 7.07*10^{-4} }$

=> $\frac{dE}{dt} =- 2.72 *10^{15} \ N/C \cdot s$

The negative sign shows that the direction of the electric field is opposite that of the current
