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.

The cell has the shape of a rectangle.
What appears to be a large space can be seen inside the cell
</span><span>Increasing the light source reveals green dots inside the cell.
The only cell that has a rectangular shape is a plant cell duo to the cell wall.
The large spaces inside the cell are the vacuoles.
The green dots are chloroplasts.

<em>When water is abundant:</em>
-Temporal regulation of stomata is used:
Open during the day
Closed at night
- At night, there is no photosynthesis, so no demand for CO2 inside the leaf.
- Sunny day = demand for CO2 in leaf is high = stomata wide open.
- As there is plenty of water, plant trades water loss for photosynthesis products.
- If the leaf's CO2 concentration is low, the stomata will stay open to continue fueling photosynthesis.
- High temperatures will also signal stomata to close.
- When limited water is available in the soil, plants try to prevent water loss.
Answer:
The nervous system and the endocrine system are both necessary to maintain homeostasis and keep the human body alive.
