Answer: Option (c) is the correct answer.
Explanation:
Photosynthesis is a process in which sunlight, carbon dioxide, and water is used by the plants to make their on food.
Plants absorb energy in the form of heat from the sunlight and thus produce glucose and oxygen from carbon dioxide and water. This absorbed energy is then used to start various chemical and biochemical reactions in the plants.
Hence, photosynthesis is an endothermic reaction.
Thus, we can conclude that a large amount of energy is required to activate the reaction.
According to Henderson–Hasselbalch Equation,
pH = pKa + log [Lactate] / [Lactic Acid]
As,
Ka of Lactic Acid = 1.38 × 10⁻⁴
pKa = -log Ka
pKa = -log 1.38 × 10⁻⁴
pKa = 3.86
So,
pH = 3.86 + log [0.10] / [0.13]
pH = 4.74 + log 0.769
pH = 4.74 - 0.11
pH = 4.63
False, many chemicals can be toxic to the drainage systems, and can make their way into the ocean harming sea life.
HI acts as an arrhenius acid in solution. It will dissociate into H⁺ and I⁻ therefore being a proton donor. (HI is actually one of the 7 strong acids)
I hope this helps.
The correct answer is - b. If available resources decrease, then competition will increase.
All living organisms in an ecosystem are specialized in accordance to the living conditions and the food sources available. If a given ecosystem experiences prolonged drought, than the resources will decrease. With a decrease in resources, the living organisms will find themselves in a situation of scarcity. That will lead to a much increased competition, with both organisms of different species, and members of the same species. That will most likely lead to a situation where only the fittest will survive, while the weaker members of the species will probably die in that period of prolonged drought as they will not be able to get the resources they need to survive.
