B- CUACCGAAUGC I’m not sure which of DNA and RNA is the correct formula I get those mixed up.
Answer:
D 2.5 g/mL
Explanation:
The density of a substance/object can be calculated by using the formula:
Density = mass/volume
Where;
Density = g/mL
Mass = grams
Volume = mL
The water displacement method was used to calculate the volume of the marble. The student places the marble in 50 mL of water in a graduated cylinder, and the water level rises to 70 mL. This means that the volume of the marble is 70mL - 50mL = 20mL
The mass of the marble is 50g
Hence, the density of the marble is as follows:
Density = 50/20
Density = 2.5g/mL
Answer:
Epidemiological Study
Explanation:
This type of study is called and epidemiological study. The design of this study uses a group or individual that have been exposed or not been exposed to a certain condition. The parameters will account for similar age, sex working habits etc. This will correctly identify if the contributing factor is the exposure of the agent or otherwise.
In a COMBINATION reaction, two or more elements or compounds form one product. Combination reaction is sometimes also refer to as synthesis reaction, it is a type of reaction in which a single new product is formed by the combination of two or more elements. The reaction is typically represented by:
X + Y = XY.
