Answer: Blood plays a very important role before cellular respiration. The blood provides oxygenated blood for the aerobic processes that takes place during cellular respiration. Glycolysis, link reaction, Kreb's Cycle and Electron Transport Chain are all the aerobic process of Cellular respiration that requires oxygen. Without blood aerobic cellular respiration cannot occur as the source of oxygen is blood. The blood provides oxygen before cellular respiration. After cellular respiration the waste materials are carried away by blood only.
Hence, blood plays an important role before cellular respiration.
Answer:
The answer is false. First part correct, second incorrect.
Explanation:
The affirmation “The polarity of an oxygen-hydrogen bond is higher than the polarity of a nitrogen-hydrogen bond” is correct: Oxygen is more electronegative than Nitrogen (3.5 O, and 3 N), then when they form a covalent bond with Hydrogen, OH-bond polarity is higher than NH-bond polarity. Nevertheless, the consequence is that alcohols (that have OH characteristic group) are more soluble in water (polar solvent) than amines (NH group). Then, second part of the affirmation is incorrect.

Explanation: Peridot is indeed a real gemstone. It is a transparent green variety of the mineral olivine. Peridot is formed under specific geological conditions, typically in volcanic rocks known as basalt and in certain types of metamorphic rocks. Its vibrant green color is a result of iron content within the crystal structure.
Historically, peridot has been found in various locations around the world, including Egypt, Myanmar, and the United States (Arizona and Hawaii). It is a popular gemstone used in jewelry, and its color can range from a light, yellowish-green to a more intense, rich green.
Peridot is also known by other names such as "chrysolite" and "Olivine." As with any gemstone, the quality and value of peridot are determined by factors like color, clarity, size, and overall appearance. You can visit CabochonsForSale to explore its types and feature.

Explanation:
Scientific notation is a way of writing large or small numbers in a decimal form also called exponential form i.e. expressed in terms of power of tens.
This simple method can ve followed when converting a number to scientific notation. We say; a × 10^x
a is the decimal number expressed in the power of tens
x is power of ten
According to the question, a male African elephant weighs 5450 kg.
To convert 5450 to scientific notation, we first of all move the decimal points to the left until we have only one number leftward
N.B: the decision point in any whole number is in front of the last number going rightwards.
We have, 5450 = 5.450
Next, we count how many times the decimal point was moved leftwards. In this case, it was moved three (3) times. Hence, the power of ten (x) is 3.
Because we moved leftwards, the power of ten will be a positive number. We have;
5.450 × 10^3 kg.
