You may have learned about the sheep clone, Dolly, in your science class. Although this experiment was greeted as a great succes

s, there are many problems with cloning. One of the ethical issues surrounding cloning has to do with the success rate of the process. This is because
A) cloning has never been and never will be possible.
B) cloning has become too successful in recent years.
C) cloning mammals has a very low success rate, and can produce severely damaged young.
D) cloning mammals has a very high success rate, and can produce severely damaged young.

Answer:

C

Explanation:

Using process of elimination, A isn't right because Dolly and other animals have been cloned. B is also not correct, because there would probably not be an Issue with the success rate due to it being high. D would also not be correct for the previous reasons, and while the last bit about damaged young is correct, the first bit is worng. Hope this helps, good luck!

Oxana [17]

Answer:

0,93 atm

Explanation:

For this we will use PV = nRT

P is what we want to find

V = 1 L

n = \frac{8.53}{223.23} = 0,038 moles

R = 0,082 \frac{L atm}{K mole}

T = 25°C = 298,15 K

P * 1 = 0,038 *0,082 * 298,15

P = 0,93 atm

A 50 gram meterstick is placed on a fulcrum at its 50 cm mark. A 20 gram mass is attached at the 12 cm mark. Where should a 40 g
alekssr [168]

Answer:

The 40g mass will be attached at 69 cm

Explanation:

First, make a sketch of the meterstick with the masses placed on it;

--------------------------------------------------------------------------

               ↓                    Δ                      ↓

             20 g.................50 cm.................40g

                         38 cm                  y cm  

Apply principle of moment;

sum of clockwise moment = sum of anticlockwise moment

40y = 20 (38)

40y = 760

y = 760 / 40

y = 19 cm

Therefore, the 40g mass will be attached at 50cm + 19cm = 69 cm

              12cm             50 cm              69cm

--------------------------------------------------------------------------

               ↓                    Δ                      ↓

             20 g.................50 cm.................40g

                         38 cm                 19 cm

the potential energy of a 40kg cannon ball is 14000j. How high was the cannon ball to have this much potential energy?
noname [10]
We will use the formula p = mgh p is potential energy. m is mass of object in kg g is acceleration due to gravity (9.8m/s²) h is height of the objects displacement in meters. p = mgh → mgh = p → h = p / mg p is 14000j, m is 40kg and g is 9.8 m/s² h = 14000 / 40 × 9.8 → h = 1400 / 392 → h = 35.7 Therefore , the cannonball was 35.7 meters high .
