Answer:
c. 10°C
Explanation:
Given that: A slice of pizza has 500 kcal.
That is to say Q = 500kcal
If the pizza was burned and all the heat were used to warm a 50-L container of cold water,
what would be the approximate increase in the temperature of the water?
We were also being told to note that; A liter of cold water weighs about 1 kg.
i.e 50-L container weighs about 50kg (mass)
∴ Since;
Q= 500kcal,
m = 50kg; &
the specific heact (c) = 1
we can find the approximate increase in the temperature of the water by using the formula:
Q = mcΔT
ΔT = 
ΔT = 
ΔT = 10°C
<span>the correct answer is B. the information that decides the characteristics of all organisms are contained in their nucleic acids. Nucleics acids are DNA and RNA. DNA have genes that code for proteins which are responsible for the structural and functional characteristics of organisms. DNA is transcribed into RNA and RNA is translated to proteins. Therefore information that is in these nucleic acids determines all the characteristics of organisms</span>
The right answers are complete gut and one-way gut.
Food is ingested by the mouth, where it is chewed and then thrown into the esophagus during swallowing.
After, there is food in the stomach
Then there is digestive absorption of nutrients in the small intestine
After that, Waste disposal and reabsorption of water in the colon (large intestine)
And finally, stool passes through the rectum (anus), where it is stored before defecation, induced by a reflex mechanism.
Well during an enzyme catalyzed reaction the enzyme bonds with a specific substrate at the active site. This is called an enzyme-substrate complex. The substrate is converted into a specific product, but the enzyme remains unchanged. Enzymes accelerate reactions by factors of at least a million.Enzymes are not used up in a chemical reaction. Usually, the enzyme will "reset" and be ready to use in another reaction. This is due to the fact that enzymes are proteins, and their shape is what they use in a chemical reaction. Initially, the enzyme has a particular shape. Something happens to the enzyme (usually a shape change, called a conformation change, brought on by the presence of two or more chemical reactants), and the enzyme catalyzes the reaction. After the reaction is catalyzed, the product is released, and the enzyme can "relax." This means it goes back to its normal shape, ready to do it all over again
Hope it helps
