Answer:
8%
Explanation:
Given that,
Mass of solute = 8 g
Mass of soultion, (mass of alloy) = 100 g
We need to find the percent by mass of 8.0g copper is added to enough zinc to produce 100g an alloy. It can be calculated by the formula as follows :
So, the percent by mass is 8%.
Answer:
. 2C- acetyl Co-A from the link reaction enters the kreb Cycle to combine with 4 Carbon Oxaloacetate to form 6- Citrate
The Citrate forms intermediate Isocitrate, which eventually formed 6-C alpha ketoglutarate.
The alpha-ketoglutarate forms the intermediate succinyl-Co A, which later formed 5C-succinate.
5C -Succinate forms 4C-fumarate, the latter formed 4C-malate- which eventually formed 4C-oxaloacetate.
The 4C of these compounds is fixed, to ensure constant availability of 4C of oxaloacatate for 2C Acetyl -CoA to bind it for the cycle to continuously occur for production of first product Citric Acid from which other products are formed from.
Explanation:
Answer: low rate
Explanation:
Claire is a Great Dane who was losing weight despite the fact that she is eating. Claire doesn't have an increase in appetite and also doesn't have enough energy that is required for her to play.
Claire is losing weight because food the enzymes in her body doesn't break down the food that she eats. When compared to a dog that was healthy, the enzymes from Claire's small intestine broke down protein at a low rate.
Answer:
B. similar to the cells just treated with the dye - 0% dead
Explanation:
According to this question, an experiment was set up in which kidney cells were treated with a chemical for different amounts of time. Hence, the independent/manipulable variable is the CHEMICAL.
Based on the observation of the group of cells, a cell that has been damaged by the chemical will appear pink when treated with dye while a cell treated with only due but no chemical will not appear pink.
A NEGATIVE CONTROL is the group in an experiment that is not treated with the independent variable i.e. doesn't receive experimental treatment. Since the independent variable in this experiment is the CHEMICAL, the negative control will be the group that doesn't receive the chemical treatment. Hence, the negative control is similar to the cells just treated with the dye - 0% dead
