This is because the photosynthesis require optimum pH to be slightly alkaline. Bases, such as sodium hydroxide (NaOH), are necessary to raise the pH to levels that are ideal for photosynthesis to occur.
Since, pH in soil, fresh water or groundwater becomes acidic, plant uptake and photosynthesis rates decrease. Sodium hydroxide (NaOH) raises pH levels and can affect photosynthesis rates.
Energy generated in ways that do not deplete natural resources or harm the environment, especially by avoiding the use of fossil fuels and nuclear power.
the answer sounds like it is b
The iris is composed of muscle layers - an outer layer of longitudinal smooth muscle and an inner layer of circular smooth muscle. The inner circular layer is innervated by the parasympathetic nerves. When these muscles contract, they that cause the pupil to constrict in bright light. the The outer layer of longitudinal smooth muscle is innervated by the sympathetic nerves. When these muscles contract, they that cause the pupil to dilate in dim light.
Answer: Option D, The cells would not be able to make food, but would be able to release energy from biomolecules.
Explanation: We should first understand roles of these two organelles in plant cell. Chloroplast- its function is to absorb sun's energy and convert the CO2 into glucose. Mitochondria- It makes energy from glucose and other molecules present in plant cell.
So, its obvious if chloroplast is not working, food will not be formed. That's why option A is incorrect. Again, functions mentioned in Option B are also incorrect, as DNA replication takes place inside the nucleus, and waste is broken down by lysosomes. Same is the reason with Option C, so its wrong option. Only Option D describes the functions correctly.
The correct answer is: B) 6 CO2 + 6 H2O ? C6H12O6 + 6 O2
Photosynthesis is a process of converting light energy to chemical energy in the form of sugars (carbohydrates). It is performed by plants, some algae and bacteria.
In the reaction of photosynthesis, sun energy combined with carbon dioxide (CO2) and water (H2O), to form glucose (C6H12O6) and oxygen (O2). Photosynthesis consists of two stages: the light-dependent reactions (in thylakoid membrane) where ATP is formed and the Calvin cycle (in stroma) where ATP is used.
