Answer:
Roots transporting water
Explanation:
Xylem are a special kind of tissue in plants. They help transport water and nutrients/minerals from the roots of the plant to the stem and the leaves. Also, the xylem help form the stem and give support to the plant.
Therefore, if the xylem is damaged, the process that is first affected is the roots transporting water.
The hydrogen ion concentration of the following pH samples is as follows:
- 7 (a neutral solution) = 0.845
- 5.6 (unpolluted rainwater) = 0.748
- 3.7 (first acid rain sample in North America) = 0.568
<h3>How to calculate hydrogen ion concentration (H+)?</h3>
The pH is a measure of the concentration of the hydrogen ion (H+) in water. This means that a relationship exists between H+ and pH of a solution.
The mathematical relationship between pH and H+ concentration ([H+]) is as follows:
pH = –log [H+]
This means that the hydrogen ion concentration (H+) of the following pH values can be calculated thus:
- log 7 (a neutral solution) = 0.845
- log 5.6 (unpolluted rainwater) = 0.748
- log 3.7 (first acid rain sample in North America) = 0.568

The precursor of a mitochondrial matrix protein is found in a mutation in the tom22 signal receptor.
Tom22 and Tom20 function as N-terminal matrix targeting sequences' outer mitochondrial membrane receptor proteins. The buildup of mitochondrial matrix-targeted proteins in the cytosol due to a malfunctioning Tom22 receptor protein may be followed by cytosolic turnover of these proteins.
The N-terminal sequence, which directs the protein to mitochondria and is proteolytically processed upon import3, is produced in approximately 70% of mitochondrial precursor proteins3. To get to the matrix, they must pass via the TIM23 and TOM complexes on the inner and outer membranes, respectively.
