There are four phyla or categories of fish, Hagfish, lampreys, cartilaginous and bonyfish.
Answer:
b. Detachment of a separate hybridized probe molecule from the template DNA
Explanation:
Molecular beacons are a type of genetic probe that enables the hybridization of oligonucleotides. These molecules have a flourishing component that binds to a nucleotide sequence and allows the identification of this nucleotide sequence in DNA or RNA without the release of radioactivity. For the use of these molecular beacons to be possible, one needs complementarity between the model DNA and the probe sequence, illumination of the hybridized beacon to detect fluorescence and proximity-based quenching of the fluorophore prior to beacon hybridization.
Answer:
requires that mitochondrial ATP synthesis and electron flow through the respiratory chain be obligately coupled.
Explanation:
The chemosmotic model was a concept formulated by Peter Mitchell, who stated that during the phases of electron transport in the respiratory chain, an intense release of energy occurs. This released energy allows hydrogen ions to be transported from within the mitochondrial matrix to the intercellular medium. The result of all of this is the occurrence of a chemosmotic gradient. However, when interpreting what occurs in the chemosmotic model, we can see that this model requires that the mitochondrial synthesis of ATP and the flow of electrons through the respiratory chain must be coupled.
Answer: 2.3 g cm^3
Explanation: In this case the rise in level of water is same as the volume occupied by the stone.
a) Volume occupied by the stone = 70 cm^3 – 40 cm^3= 30 cm^3
b) Density = mass/volume
= 69g/30 cm^3 = 2.3 g cm^3
