Answer:

Explanation:

1 advantage of genetic engineering:

It allows for a faster growth rate. Because with genetic engineering, plants and animals are allowed to be modified so their maturity would occur at a quicker pace.

1 disadvantag of genetic engineering:

The nutrition value of foods can be less. For example, in a research show that genetic enginnering make chicken increase the fat content by 220% but reduced the amount of protein.

1 advantage of cloning:

When cloning, the object would be able to create tissue and organs that doctor can use when needed during the surgery.

1 disadvantage of cloning:

If original organism has genetic deffects, it will be passed down through all the continuous generations

1 advantage of artificial selection (can be called as selective breeding):

It will provide improvements to plants and animals. For example, seedless fruits, increast the tast of food, etc.

1 disadvantage of artificial selection (can be called as selective breeding):

It may lead to a lack of variety in plant or animal species. As the breeding is selective so the variety in plant would be decrease. For example, people like seedless fruits than normal included-seed fruit so that would make the new fruit become more popular and may lead to decrease the diversity in fruits.

Hope this help you :3

How original were Newton’s contributions to science? (In what ways did Newton depend on the mechanical view?)
kvasek [131]
Newton's new “reflecting telescope” was more powerful than ... Before Newton, scientists primarily adhered to ancient theories on ... laws of motion laid the groundwork for classical mechanics. Newton's research on motion helped give credibility to the heliocentric view. Newton also helped pioneer telescopic innovations, and he is sometimes credited with inventing the first reflecting telescope. He also conducted experiments using the prism, and developed a theory about the nature of color and light.

An Olympic discus thrower (~100 kg) launches the 2.0 kg discus by spinning rapidly (~4 times per second) with arm outstretched (
vladimir1956 [14]

Answer:

F = 1263.03 N

Explanation:s

given,                      

mass of the disk thrower = 100 Kg

mass of the disk = 2 Kg                

angular speed of the disk  = 4 rev/s

arm outstretched = 1 m                  

centripetal force of the disk in the circular path

F = m ω² r                        

ω = 4 x 2 x π        

ω = 25.13 rad/s

F = m ω² r                      

F = 2 x 25.13² x 1

F = 1263.03 N                                              

hence, centripetal force equal to the F = 1263.03 N

When you drink cold water, your body must expend metabolic energy in order to maintain normal body temperature (37° C) by warmi
Gelneren [198K]

Answer:

7.72 Liters

Explanation:

normal body temperature = T_body =37° C

temperature of ice water = T_ice =0°c

specfic heat of water = c_{water} =4186J/kg.°C

if the person drink 1 liter of cold water mass of water is = m = 1.0kg

heat lost by body is Qwater =mc_{water} ΔT

                                           = mc{water} ( T_ice - T_body)

                                             = 1.0×4186× (0 -37)

                                             = -154.882 ×10^3 J

here negative sign indicates the energy lost by body in metabolic process energy expended due to brisk - hour long walk is Q_{walk} = 286 kilocalories

            = 286×4186J

so number of liters of ice water have to drink is

n×Q_{water} =Q_{walk}                                                                        n= Q_{walk}/ Q_{water}

= 286×4186J/154.882×10^3 J

 = 7.72 Liters
