<h3>What is  DNA hybridization?</h3>

In the study of genome, DNA hybridization is known to be a kind of a molecular biology method that is often used to know the measures or the degree of genetic similarity that exist between a given pools of DNA sequences.

DNA hybridization is also seen as ability of two  given strand of complementary DNA that tends to pair with another strand and it is one that  can be used to find out other similar DNA sequences in two other kinds of species or within a given genome of a single species.

Note that in the case above, The technique that is known to be  illustrated is said to be DNA hybridization.

In casting experiments performed using a certain alloy.
jeyben [28]
Answer:
A) Cm = 2.232 s/mm²
B) Time taken to solidify = 74.3 seconds
Explanation:
(A) Since a side is 50mm and all sides of a cube are equal, thus, Volume of the cube is;V = 50 x 50 x 50 = 125,000 mm³
There are 6 faces of the cube, thus Surface Area A = 6 x (50 x 50) = 15,000 mm²
So, Volume/Area = (V/A) = 125,000/15,000 = 8.333 mm
Cm is given by the formula; Cm =[Tts] /(V/A)² where Tts is time taken to solidify and it's 155 seconds in the question. Thus;
Cm = 155/(8.333)²= 2.232 s/mm²
(B) For;Cylindrical casting with D = 30 mm and L = 50 mm.;
Volume of cylinder is;
V = (πD²L) /4
So,V = (π x 30² x 50)/4 = 35,343mm³
Surface area of cylinder is;
A = (2πD²)/4 + (πDL)
Thus, A = ((π x 30²)/2) + (π x 30 x 50) = 6126 mm²
Volume/Area is;
V/A = 35,343/6126 = 5.77 mm
Same alloy and mold type was hsed as in a above, thus, Cm is still 2.232 s/mm²
Since Cm =[Tts] /(V/A)²
Making Tts the subject, we have;
Tts =Cm x (V/A)²
Tts = 2.232 x (5.77)² = 74.3 seconds

Around half of the electricity used in the United States is powered by burning coal. The United States is a developed country wi
Zinaida [17]

The two options would be to reduce the demand for energy and or use renewable sources of energy. Options C and D are correct.

<h3>How to reduce carbon emission</h3>

The burning of fossil fuels such as coal and crude oil-derived fuels generates a large amount of emissions.

In order to cut down on the emission, the demand for energy needs to be lowered by all means. In addition, instead of using fossil fuels, renewable sources of energy can be used.

Greenhouse gases such as carbon dioxide, oxides of sulfur, and water vapor are produced largely as by-products of burning fossil fuels. These gases form a layer in the atmosphere and trap reflected solar radiation.

By doing so, the increase the average annual temperature of the planet (global warming). The warming of the planet has several negative effects on the climate and the ecosystems as a whole.

Renewable sources of energy, on the other hand, have very little to no greenhouse gas emissions.

The conventional theory of the formation of the galaxy brainly.
Nataly_w [17]
<h3>What is conventional theory of the formation of the galaxy ?</h3>

The conventional theory of the formation of the galaxy can be regarded as one that stressed that the formation of milky way was done  relatively short time some million years ago.

And this was when spherical cloud of gas collapsed as a result of pressure the particular gravity which was surrounded by a halo.

Therefore, formation of the galaxy  was recorded to occur  roughly 12 to 13 billion years ago .
