According to the Dalton's atomic theory, we can see that there are two atoms that compose the water molecule.
<h3>What is the atomic model?</h3>
The atomic theory states that matter is made up of small particles called atoms. These atoms are capable of independent existence and can take part in chemical reaction.
From the Dalton's atomic theory, we can see that there are two atoms that compose the water molecule. These atoms are hydrogen atom and the oxygen atom.

One class of phospholipids, the phosphoglycerides,are composed by three parts that define this type of lipid:
- backbone of glycerol
- two long-chain fatty acids
-phosphoric acid
- and one organic group
Sphingolipids are similar in shape but they have a different component. Instead of having glycerol, which is the case for phosphoglycerides, they use sphingosine.
To form a Sphingolipid are necessary:
-sphingosine as the backbone
-phosphate
-an organic group
Answer:
The correct sequence of steps in citric acid cycle has been mentioned below -
Explanation:
- 2 acetyl CoA molecules are produced from the breakdown of one glucose molecule.
- Acetyl CoA combines with oxaloacetate to form citrate and releases CoA.
- Two carbon atoms are released from acetyl CoA and combine with oxygen to form carbon dioxide.
The sequence of steps is correct in the question i.e. 1 → 2 → 3
These are the first three steps in the citric acid cycle which occurs during the cellular respiration.
Anti-parallel DNA strands refer to those DNA molecules which contain 2 DNA strands that were held together by hydrogen. In cases that the DNA strands are not anti-parallel the non-symmetrical hydrogen bond will not be possible and will cause some issues.
