Answer:

Genetic engineering because the genes of the plants were modified.

Explanation:

We can eliminate the second and fourth ones right off of the bat because artificial selection is breeding organisms until they display a trait or a series of traits that is desired, but in this situation, the scientist directly altered the DNA. Genetic engineering, just like all other technologies, aren't necessarily helpful to society all of the time; they always have their draw backs. The answer has to be the third one because the DNA is directly altered, just like the answer choice says.

During the annual shuffleboard competition, Renee gives her puck an initial speed of 8.12 m/s. Once leaving her stick, the puck

shutvik [7]

<h2>Answer:2.65 seconds</h2>

Explanation:

Let $a$ be the acceleration.

Let $u$ be the initial velocity.

Let $v$ be the final velocity.

Let $t$ be the time taken.

As we know from the equations of motion,

$v=u+at$

Given, $v=0\\u=8.12ms^{-1}\\a=-3.06ms^{-2}$

$0=8.12-3.06t$

$t=2.65sec$

State how you agree or disagree with the following statement. A good circuit cannot have internal resistance.

Rashid [163]

Answer: I do

Explanation:

Resistance opposes current thereby reducing the amount of current that flows through a circuit. In other words, it leads to a loss of electrical energy.

Ideally speaking, a good circuit should have no internal resistance as this would lead to more energy having to be supplied to overcome that resistance. External resistance however, is not a bad thing. For instance, oxygen being removed from lightbulbs.
