Answer:
Atmospheric carbon dioxide is the raw material for photosynthesis, which plants rely on for producing sugars and other organic compounds.
Explanation:
The most accurate statement that supports the researcher's claim is that atmospheric carbon dioxide is the raw material for photosynthesis.
Photosynthesis is the process by which green plants manufactures their food in the presence of carbon dioxide and water using sunlight.
The product is usually glucose and oxygen.
The chemical equation is shown below;
6CO₂ + 6H₂O → C₆H₁₂O₆ + 6O₂
This raw material is a by-product of cellular respiration in human beings. Other process also releases carbon dioxide. Green plants uses this organic material to manufacture its food through photosynthesis.
We can attribute the increased growth rate in plants to the proliferation of the gases in the atmosphere.
Answer:
The correct answer is the opposite of the positive phototropism.
Explanation:
The vines in the tropical rain forests in the given case would primarily exhibit the growth pattern opposite in the direction of positive phototropism. The response of the plant towards the source of light is termed as the positive phototropism. On the other hand, the phenomenon that results in the growth of the plant in the reverse direction is termed as negative phototropism.
Thus, in the given case, in order to reach a large tree, the vines in the tropical rain forests would primarily show a growth movement, which would be the opposite of positive phototropism.
Transpiration is when the plant loses water through its leaves.Respiration is when the plant breaks down the sugar in its cell to release energy
Answer:
The company used it to improve the immunity of bacterial cultures against viruses and many food manufacturers now use the technology to produce cheese and yoghurt. Since then the technology has been used to delete, insert and modify DNA in human cells and other animal cells grown in petri dishes.
