Answer:
D
Explanation:
The correct answer would be that the origin of all cells can be traced to previous or pre-existing cells.
According to the cell theory which is made up of three parts;
- <em>The cell represents the basic unit of all life.</em>
- <em>All living organisms are made up of cells.</em>
- <em>Cells do not arise spontaneously, but only from pre-existing cells.</em>
Hence, the discovery that the origin of all cells is traceable to previously existing cells supports the latter part of the cell theory.
The correct option is, therefore, D.
Answer:
The last one and the second one
Explanation:
Both of those are technically correct. There must be a charge through the book before an electrical force can act on it. Id have to say the last one
Answer:
They are building blocks for larger polysaccharide which are important in structural rigidity of cells.
Polysaccharides such as Starch and Cellulose which are instrumental in cell structure and rigidity are formed from chains of monosaccharides.
They are also useful in the provision of energy which is used in cell functions (metabolism).
Monosaccharides such as Glucose, Sucrose are useful in provision of energy for physical and metabolic activities of the body.
The correct answer is: It enters the citric acid cycle and associates with a 4-carbon molecule (OXALOACETATE), forming citric acid, and then through redox reactions regenerates the 4-carbon molecule.
The citric acid cycle is a cyclic process (part of the cellular respiration) where acetyl CoA is modified in the mitochondria to produce high-energy intermediate molecules for the oxidative phosphorilation (production of ATP).
Answer:
D) 5'-ATGC-3' with 5'-GCAT-3'
Explanation:
In a double helix DNA, adenine always pairs with thymine and cytosine pairs with guanine. Also, the two strands of a double helix DNA are antiparallel, that is, the 5' end of one strand lies opposite to the 3' end of another strand.
Therefore, a DNA strand with base sequence 5'-ATGC-3' would have a complementary strand 5'-GCAT-3'.
Double stranded DNA: 5'-ATGC-3'
3' TACG 5'
