The correct option is A.
The DNA from one specie differ from the DNA of another specie on the basis of their base ratio. The base ratio refers to the percentage of purine to pyrimidine in a DNA molecule. The base ratio is the one that is responsible for the variability that is observed in chromosomes from different species.

protoporphyrin ix fluorescence and photobleaching during interstitial photodynamic therapy of malignant gliomas for early treatm
Marysya12 [62]

Prior to therapy, a high PpIX fluorescence was observed in three patients; however, after iPDT, this fluorescence was entirely photobleached. These patients' viable tumor sections had high PpIX concentrations (mean PpIX uptake per tumor: 1.4-3.0 M).

<h3>Briefing:</h3>

However, no or just minimal PpIX uptake (0-0.6 M) could be seen in the remaining two cases. Strong PpIX uptake patients demonstrated therapeutic response and long-term clinical stabilization (no progression at 29, 30, and 36 months); the remaining two patients experienced early treatment failure (death after 3 and 9 months).

<h3>Describe fluorescence:</h3>

Two steps make up the chemical process of fluorescence first, a chemical fluorophore such a protein or carotenoid absorbs shorter-wavelength light (excitation), and then some of the absorbed energy is released as longer-wavelength light (emission).

The gravitational pull on planet A is greater than on planet B. Which of the
RideAnS [48]
As relevant to the question here, an object’s mass refers to an intrinsic property of the object while weight refers to a force that depends on the local gravitational field. So, if an object moves between planets with different gravitational pull, the object’s weight would change but its mass would not.

The third option would thus be the correct one (the object of an invariant mass would have a lesser weight on planet B than on planet A).

Answer:

A

Explanation:

The energy carried by electromagnetic waves is sometimes referred to as radiant energy. Electromagnetic waves do not require a medium for propagation hence they can travel through vacuum and are known to transmit enormous amount of energy.

Electromagnetic waves transmit energy away from the source of the wave. Hence the answer chosen in the answer section above.
