There are 4 main functions of roots: absorption of water and inorganic nutrients. anchoring the plant body to the ground and supporting it. storage of food and nutrients. I hope this helps!
Answer: The second image best represents the relationship of the concentration of hydrogen ions between water, vinegar and ammonia.
Explanation: pH is the measure of alkalinity and acidity of a substance in a logarithmic scale.
Mathematically,
![pH=-\log[H^+]](https://tex.z-dn.net/?f=pH%3D-%5Clog%5BH%5E%2B%5D)
The solutions which lie in the pH range of 0 - 6.9 are considered as acidic solutions and they have more hydrogen ion concentration.
The solution which has a pH value of 7 is considered as a neutral solution and this solution has same hydrogen and hydroxide ion concentration.
The solutions which lie in the pH range of 7.1 - 14 are considered as basic solutions and they have less hydrogen ion concentration.
- For vinegar, the hydrogen ion concentration is very high.
- For water, the hydrogen ion concentration will be equal to the hydroxide ion concentration.
- For ammonia, the hydrogen ion concentration is very less.
Answer:
These strands are clones, however, due to their low genetic variability, the population becomes susceptible to diseases taking place in plants. Pando comprises grove of about 47000 trunks, these all are genetically similar that develops from a solitary underground species, Quaking aspen tree. Pando is an extremely large clone.
However, for the past some years, scientists are worried about Pando's health. For the past thousands of years, Pando was living in fine tune with the native wildlife population, but for the past some years, a shift in balance is noticed. As in the absence of the development of novel stems, nothing will be able to substitute the natural withering of the older ones, if this goes on, the death of Pando will take place.
99% of the water is used for the "Transpiration" by the plants.
<h2>C) option is correct </h2>
Explanation:
- The spinal cord has numerous groups of nerve fibers going towards and coming from the brain
- These have been collectively called the ascending and descending tracts of the spinal cord, respectively, these tracts are responsible for carrying sensory and motor stimuli to and from the periphery (respectively)
- The ascending tracts transmit sensory information from the sensory receptors to higher levels of the CNS
- The descending tracts originate from different cortical areas and from brain stem nuclei
- The descending pathway carry information associated with maintenance of motor activities such as posture, balance, muscle tone, and visceral and somatic reflex activity
