Farmers want their plants to photosynthesise as much as possible in order to increase their crop rate.
Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide. Increasing the light intensity will boost the speed of photosynthesis.
Sometimes photosynthesis is limited by the concentration of carbon dioxide in the air. Even if there is plenty of light, a plant cannot photosynthesise if there is insufficient carbon dioxide.
If it gets too cold, the rate of photosynthesis will decrease. Plants cannot photosynthesise if it gets too hot.
Farmers can use their knowledge of these limiting factors to increase crop growth in greenhouses. They may use artificial light so that photosynthesis can continue beyond daylight hours, or in a higher-than-normal light intensity. The use of paraffin lamps inside a greenhouse increases the rate of photosynthesis because the burning paraffin produces carbon dioxide, and heat too.
Answer:
The correct answer is option D, that is, bottleneck effect.
Explanation:
A phenomenon, which occurs due to events like earthquakes, floods, or other natural calamities that result in the severe declination in the size of a particular population is known as the bottleneck effect. The bottleneck effect is an extreme illustration of genetic drift that results in the reduction of a population's genetic variability.
With the decline in the size of a specific population, a reduction in the genetic variability of the same population is witnessed due to the loss of alleles. This eventually makes the population vulnerable to pollution and diseases. Hence, the given case is an example of the bottleneck effect.
Decreased pH would increase the amount of oxygen unloaded by hemoglobin into peripheral tissues.
<h3>What is hemoglobin?</h3>
- The iron-containing oxygen-transporting metalloprotein known as hemoglobin.
- The abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs.
- The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.
- Iron deficiency anemia is characterized by low hemoglobin that is brought on by low iron levels.
- Low hemoglobin is most frequently caused by a diet that is inadequate in iron.
- Low hemoglobin levels can cause headaches, exhaustion, and pale complexion.
- Surgery, iron therapy, and iron supplementation are all options for treating low hemoglobin.
- Red blood cells include the protein hemoglobin, which transports oxygen to your body's organs and tissues and carbon dioxide from those tissues back to your lungs.
- A low red blood cell count if a hemoglobin test finds that your hemoglobin level is lower than normal (anemia).
