Answer:
Temperature of the fridge
Explanation:
The independent variable is the temperature of the fridge.
The hypothesis statement would be "if coffee beans are soaked overnight in a fridge then cold coffee is produce because of the temperature of the fridge".
An independent variable is the cause in an experimental design or set up. It is the variation on this variable that produces the effect we desire to study.
The dependent variable is the cold coffee. It is the cause of putting the coffee in the fridge of overnight.
The second statement is correct.
There are two main<span> types of physical weathering: Freeze-thaw occurs when water continually seeps into cracks, freezes and expands, eventually breaking the rock apart. Exfoliation occurs as cracks develop parallel to the land surface a consequence of the reduction in pressure during uplift and erosion.</span>
Answer;
-The most appropriate answer is Lipids
Explanation;
-Lipids is among the four biological biomolecules, the others being proteins, carbohydrates and nucleic acids.
-Lipids are made up of fatty acids and glycerol and are composed of elements carbon, hydrogen, oxygen and they may also contain phosphorus, like in the case of phospholipids which are mainly components of the cell membranes.
-They take two forms, namely; fats and oils. Therefore, the oil form of lipid may be used as lamp oil.
The answer is A)<span> the desired gene is inserted into the genomes of the pork.
</span>
The techniques of genetic engineering are used to introduce hybrid genes for some desired substance or protein or trait into other organisms. Here, the desired gene is inserted into pork's genome and as a result, it has a <span>higher flesh-to-bone ratio</span><span>.</span>
<span>- B) is not the right answer because it is not necessary to change all the genes in the pork genome or it will be transformed into totally different organism.</span>
<span>- C) is not the right answer because the pork does not have plasmids.</span>
