Answer:
A measure of how innaccurate a measurement is, standardized to how large the measurement is. Found by the formula (measured value-actual value)/actual value*100%J
Explanation:
Simply a percentage, the definition of it is up above.
Answer:
The final volume is the sum of the initial volume and the volume of the object.
Explanation:
Since we know that the volume of the object is the difference between the final and the initial volume, let the volume of the object be ∆V, let the initial volume be V1 and let the final volume be V2.
From;
∆V= V2 - V1
V2= ∆V + V1
Hence the answer above
Sex cells only contain one chromosome from each pair. When an egg cell and spermcell join together, the fertilised egg cell contains 23 pairs of chromosomes..
I am 99% sure that is the answer.
Answer:
1 and 2
Explanation:
1- some fungi are harmful to us like Aspergillosis, however not all of them are harmful to us.
2- all fungi are eukaryotes because they have a well organized cell.
3- fungi do not contain green pigment so therefore cannot do photosynthesis. They instead use digestive enzymes to digest the food externally.
4- not all fungi are harmful to humans or animals, for example yeast is a fungus but it is used a lot in cooking/baking.
Hope this helps good luck!
Answer:
The glycolysis occurs in the citosol, the pyruvate oxidation occurs in mitochondrial matrix. The citric acid cycle takes place in the mitochondrial matrix and the oxidative phosphorylation occurs in the inner membrane of the mitochondria.
Explanation:
There are several enzymes located in the cytosol of the cell that degrade glucose to generate two pyruvate molecules (glucose that has 6 carbons is broken down into two pyruvate molecules, which have 3 carbons each)
The pyruvate generated from glycolysis leaves the cytosol and enters the outer membrane of the mitochondria and then passes to the mitochondrial matrix. Within the mitochondrial matrix, pyruvate undergoes oxidative decarboxylation where the enzyme pyruvate dehydrogenase is finally constituted.
Inside the mitochondrial matrix, the pyruvate dehydrogenase binds with coenzyme A, and this begins the citric acid cycle where they also bind to the oxal acetate and cycle the acid. The reactions release carbon as CO2 and NAD + and FAD + are reduced to NADH and FADH2, respectively.
In the inner membrane of the mitochondria. NADH and FADH2 re-oxidize and release protons and electrons. Protons pass into the intermembrane space, while electrons enter the mitochondrial matrix after passing a complex protein system. As the proton output has a gradient in favor, there is a decrease in the pH in the mitochondrial matrix, but they are returned to its interior by an ionic channel. These protons join with O2 molecules and generate water. Next to this ionic channel is the ATP synthetase that uses energy to convert ADP + P into ATP
