Answer:
The correct answer is - option b) lipids
Explanation:
Lipids are one of the nutrients that are necessary to the body of an individual organism as it plays role in different ways such as energy storage, cell signaling, component of the cell membrane and many more hat maintain homeostasis in organisms body.
These nutrients are made up of fatty acid and glycerol long chains so these are polymer of glycerol and fatty acid and called triglyceride which provides maximum energy in comparison to other nutrients in need.
Thus, the correct answer is - option B) lipids.
First we must understand the balanced chemical equation:
Pb(NO3)2 + K2CrO4 ==> PbCr04 + 2KNO3
This shows us that two moles of potassium nitrate are formed from 1 mole of lead nitrate or potassium chromate solution. The next step is to find out how many moles of each reactant there are. Note the word Molar is a concentration that simply means moles per liter.
2.25L of 1.5M lead nitrate = 2.25x1.5 = 3.375 moles of lead nitrate
1.15L of 2.75M potassium chromate = 1.15x2.75 = 3.1625 moles
The important part here is to see that the number of moles of the reactants are different. We know the number of moles of products will be dependent on the number of moles of reactants, and in this case there is less potassium chromate than there is lead nitrate, so this is the limiting factor as there is a one to one relationship with both reactants. Therefore, the number of moles of potassium nitrate produced is 2 x number of moles of potassium chromate. i.e. 6.325 moles of potassium nitrate is liberated.
To work out the number of grams, we must find the molar mass (the mass of one mole) of KNO3, which is the sum of the molar mass of each of its component atoms that make up the molecule. I've looked this up as 101.1 grams per mole.
Now we simply times the molar mass by the number of moles to yield the final grams liberated: 6.325 moles x 101.1 grams/mole = 639.4 grams of potassium nitrate is liberated from this reaction.
Answer:
A
Explanation:
Mitochondria are the sites of the reactions of oxidative phosphorylation, which result in the formation of ATP. The size and coding capacity of the mitochondrial DNA varies considerably in different organisms, and encodes rRNAs, tRNAs and essential mitochondrial proteins.
Lizard belongs to chordate phylum.

Answer:
Option (B).
Explanation:
Peyer's patches are the small masses of aggregated small lymphatic tissues and provide immunity to an organism. Peyer patches are discovered by the scientiest Johannan Cornard Peyer.
Peyer's patches are located in the ileum region of small intestine. These patches control the growth of harmful bacteria and regulates the growth of intestine bacteria. T
Thus, the correct answer is option (B).
