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.

how are mutations continually being generated in a population (what are some of the causes of mutatuions?) explain
vampirchik [111]
Some causes could be the mother smoking, drinking, doing drugs etc. Or even simply her body doesn’t fully accept the baby growing inside her so it acts out against it. Sounds strange but it happens. Also if the mother is sick with Zika or another virus, it can harm the baby’s growth.

2. Why is this change in global temperature a concern
12345 [234]
Past climate changes led to extinction of many species, population migrations, and pronounced changes in the land surface and ocean circulation. The speed of the current climate change is faster than most of the past events, making it more difficult for human societies and the natural world to adapt.

What do they mean when people say that digestion starts in your mouth?
guajiro [1.7K]
The mouth is the beginning of the digestive tract. In fact, digestion starts here as soon as you take the first bite of a meal. Chewing breaks the food into pieces that are more easily digested, while saliva mixes with food to begin the process of breaking it down into a form your body can absorb and use. Hope I’ve helped ;)

What happens when light waves passes through glasses
Andreyy89
Refraction is an effect that occurs when a light wave, incident at an angle away from the normal, passes a boundary from one medium into another in which there is a change in velocity of the light. Light is refracted when it crosses the interface from air into glass in which it moves more slowly. Since the light speed changes at the interface, the wavelength of the light must change, too. The wavelength decreases as the light enters the medium and the light wave changes direction. We illustrate this concept in Figure 3 by representing incident light as parallel waves with a uniform wavelength . As the light enters the glass the wavelength changes to a smaller value '. Wave "a" passes the air/glass interface and slows down before b, c, or d arrive at the interface. The break in the wave-front intersecting the interface occurs when waves "a" and "b" have entered the glass, slowed down and changed direction. At the next wave-front in the glass, all four waves are now traveling with the same velocity and wavelength
