Answer:

In cellular respiration, glycolysis is the first step in which glucose is oxidized into pyruvate. The electrons released by glucose during its oxidation is taken by NAD⁺ which gets reduced to NADH in glycolysis.

This NADH then again get oxidized by transferring the electron to oxygen through an electron transport chain present in mitochondria. This electron transfer is necessary for ATP generation for cell and regeneration of NAD⁺ that can again be used in glycolysis.

So when a chemical used that prevents NADH from being oxidized then no electron will be transferred to oxygen so oxygen will not be consumed and no ATP will be generated and also no NAD⁺ will be available for glycolysis.

Therefore all the metabolic process will stop and no consumption of oxygen will occur which will lead to the death of the seedling.

What percent of iodine has decayed if 5 half lives have passed?
goldfiish [28.3K]

Hello!

A half-life is the amount of time it takes half of an element to decay. For example, after one of carbon's half-life, half of carbon would've decayed.

Now, we can calculate how much has decayed if 5 half lives have passed.

1 -> 50% (1) -> 25% (2) -> 12.5% (3) -> 6.25% (4) -> 3.125% (5)

Therefore, there would be 3.125% left of iodine. However, your question is asking what percent has decayed. Therefore, subtract 3.125 from 100% to get your final answer.

100 - 3.125 = 96.875

Therefore, your final answer is 96.875% of iodine has decayed if 5 half lives have passed.

Hope this helps!

describe the basic process of evolution by natural selection. Describe the underlying genetic basis and role of the environment
shepuryov [24]

Answer AND Explanation:

Darwin describes natural selection as a process whereby nature selects those organisms that have favourable characteristics to be parents of the next generation. The individuals possessing the favourable traits are better suited to the prevailing environmental conditions. This enables them to stand a better chance to survive in the struggle for existence due to limited resources.
