Plants need oxygen to survive , no oxygen mean the plant will diePlants do need oxygen to survive. They respire (take in oxygen, give off carbon dioxide) the same way that animals do. The difference is that during the day, plants also perform photosynthesis, in which they take in carbon dioxide and give off oxygen.Plants require oxygen for respiration to carry out their functions of water and nutrient uptake. In soil adequate oxygen is usually available, but plant roots growing in water will quickly exhaust the supply of dissolved oxygen and can be damaged or killed unless additional air is provided. A common method of supplying oxygen is to bubble air through the solution. It is not usually necessary to provide supplementary oxygen in aeroponic or continuous flow systems.Oxygen is vital ingredient in plant survival
Answer: alpha
Explanation: Alpha particles are fast moving streams of positively charged particles that are shown to be Helium nuclei. They have a mass
number of 4 and an atomic number of 2 and a charge of +2. Alpha particles are represented as 4He2. When 238U92 becomes 234Th90, it emitted a helium nucleus 4He2. The equation for the decay is 238U92 ---> 234Th90 + 4He2.
<h2>Genetic diversity </h2>
Explanation:
If the environment changes, the species runs the risk of not having the genetic diversity to be adaptable to that change and could go extinct
- Genetic diversity is the diversity or genetic variability within species
- The huge variety of different gene sets defines an individual or a whole population's ability to tolerate stress from any given environmental factor
- While some individuals might be able to tolerate an increased load of pollutants in their environment, others carrying different genes might suffer from infertility or even die under the exact same environmental conditions;the former will continue to live in the environment the latter will either have to leave it or die
- Any change in the environment - natural or human induced causes a selection of events that only the fittest survive
- In case of elephant seals,overhunting reduces the sum of genes available,thus leaving behind a population that is less capable of tolerating any further natural or human disturbances in environment
- The loss of genetic diversity within a species can result in the loss of useful and desirable traits
<span>The main light-absorbing pigment for photosynthesis is known as chlorophyll. This light absorbing pigment is found in many organisms, primarily in a variety of plant and bacteria species. Chlorophyll is necessary because it allows the light to be absorbed and allow energy to be absorbed by the organism in order to carry out a multitude of metabolic processes.</span>
