What are the negative impacts on Genetically Modified Crops?

2 answers:

8 0

Biodiversity Loss: The use of some GM crops can have negative impacts on non-target organisms and on soil and water ecosystems. For example, the expansion of GM herbicide-tolerant corn and soy, which are twinned with herbicides, has destroyed much of the habitat of the monarch butterfly in North America.

One specific concern is the possibility for GMOs to negatively affect human health. This could result from differences in nutritional content, allergic response, or undesired side effects such as toxicity, organ damage, or gene transfer. Research indicates that GM crop technology can result in a net increase in herbicide use and can foster the growth of herbicide resistant weeds. In addition, there is concern that the use of GM crops may negatively impact the agriculture ecosystem.

A mad scientist wants to collect massive amounts of charge on basketball sized aluminum balls. The scientist wants to place 6 C

vitfil [10]

The distance between two basket ball sized aluminium balls is 9714 m.

Explanation:

Coulomb's law, or Coulomb's inverse-square law, is an experimental law of physics that quantifies the amount of force between two stationary, electrically charged particles. The electric force between charged bodies at rest is conventionally called electrostatic force or Coulomb force .

Coulomb's law formula => F = (k * Qb1 * Qb2)/r²

Given data :-

charge on ball 1 Qb1 = 6C

charge on ball 2 Qb2 = 14C

Force exerted F = 8000 N

k = 8.988 x 10^9 Nm²C−²(coulomb's constant).

substituting given values in the coulomb's formula

8000 = (( 8.988 x 10^9)*6*14)/r²

shifting r and 8000 to other sides

r² = (756 * 10^9)/8000

r = 9714 m.

Therefore the distance between two balls is r = 9714 m.

An astronaut on a small planet wishes to measure the local value of g by timing pulses traveling down a wire which has a large o

8_murik_8 [283]

Answer:

The gplanet is 0.193 m/s^2

Explanation:

The speed of the pulse is:

$v=\frac{lengthofthewipe}{traveltime} =\frac{1.6}{0.0656} =15.24m/s$

$v=\sqrt{\frac{MgL}{m} } \\v^{2} =\frac{MgL}{m} \\g=\frac{mv^{2} }{ML}$

where

m=mass of the wire=4 g= 4x10^-3 kg

M=mass of the object= 3 kg

Replacing values:

$g=\frac{4x10^{-3}*15.24^{2} }{3*1.6} =0.193 m/s^{2}$

The direction of deflection of an electron beam in a magnetic field can be determined by which of the following?

amid [387]

Answer:

Right Hand Rule

Explanation:

When a charged particle travels in a magnetic field, it experiences a force whose magnitude is given by:

$F=qvBsin\theta$

where

q is the charge of the particle

v is the velocity

B is the magnetic field strength

$\theta$ is the angle between the directions of v and B

The direction of the force can be determined by using the Right Hand Rule, as follows:

- index finger: this should be put in the direction of the velocity

- middle finger: this should be put in the direction of the magnetic field

- thumb: this will give the direction of the force -> however, for a negative charge (as the electron) the direction must be reversed, so it will be opposite.
