Describe the procedure of water reaching the leaves from the roots of a plant

Biology
1 answer:
Lisa [10]3 years ago
8 0
The water enters the xylem first by osmosis. Water moves from the soil to the root hair cell down a water potential gradient, and to the root cortex cell from a higher water potential to a lower water potential, this process will be repeated until water enters xylem. Because transpiration is occurring in the leaf, water is lost so there is a lower water potential inside the leaf. Osmosis moves water from the xylem to the leaf because the xylem has a higher water potential. Water moves from the xylem to the cells of the leaf. This pulls water up the xylem via cohesion which is the process of water molecules attracting each other and sticking together. Water does not fall down the xylem as here is adhesion which is the process of water molecules sticking to the inside of the xylem.

Which of the following is not required for the proper use of molecular beacons?
arlik [135]

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.

If an element Has 35 protons and 36 electrons is it called an cation or anion
kozerog [31]

Answer:

In a neutral atom the number of protons = the number of electrons. 35 protons = 35 electrons. But Bromine anion with a charge of -1 has one extra electron so 35 +1 = 36 electrons. 36 electrons is the number of electrons in the stable inert gas Krypton. ... Protons + neutrons = Mass putting in known values.
