Answer:
plants process oxygen for respiration as an aerobic organism and also produces it, light can regulate this metabolism, which means that in the presence of light oxygen generation occurs as well as consumption and when there is darkness only consumption will occur Thus, when calculating the amount of oxygen that a plant produces during photosynthesis, it will be necessary to subtract the oxygen it consumes, from which it is deduced that the rate of oxygen consumption will not have variations and will be the same in the day and in the At night, so the change of oxygen in the dark is subtracted with the change of volume of oxygen in the light phase

b) 
c) 
d) 
e) 
Explanation:
When two heterozygous plants with genotype Bb are crossed, following offspring are produced
Bb * Bb
BB, Bb, Bb, bb
so the probability of blue offspring is 
and the probability of white offspring is 
a) Probability of all 4 peas as blue
b) Probability of 3 blue and 1 white
c) Probability of 2 blue and 2 white
d) Probability of 1 blue and 3 white
e) Probability of all white
Answer:
In an ecosystem, all organisms benefit in the process of transformation of energy.
Explanation:
An ecosystem works thanks to the constant transformation of energy. In the case of microorganisms that act as producers, they benefit the rest of the ecosystem in terms of energy transfer because they acquire the energy from a lowest trophic level to make it available for higher trophic levels.
In the case of the primary consumers, they are feeding from the primary producers, incorporating that energy to be part of the food chain. For example, bacteria in the soil are primary producer microorganisms; they transform organic material to make it available for small individuals. A soil worm is a primary consumer microorganism which will feed from this organic material transformed by the bacteria. The worm will then produce food and will be food for herbivores to continue with the flow of energy in the food chain.
Alkali metals displace Hydrogen from H2O in order to make the Hydroxide ion, the displaced Hydrogen is formed as H2 gas.
