Answer:
Dust bowl resulted from extreme drying and loosening of the soil that resulted in soil erosion by wind. Thus, it can be related that poor agricultural practices like over plowing , over grazing and leaving the land barren are human activities that must have contributed to the dust bowl.
Explanation:
- Dust bowl is referred to a period in early twentieth century when the the American and Canadian prairies faced severe dust storms.
- These dust storms resulted from severe drought and failure of practices to prevent soil erosion.
- Several people and livestock died as a result of choking.
- Over plowing, removal of top soil and small grasses exposed the soil to eroding winds and caused the dust storms.
<h2>Sodium channels </h2>
Explanation:
Depolarization is a result of sodium channels opening as a result of chemical or pressure-based stimuli
- Depolarization starts when a threshold stimulus applied on a neuron via Na+ mechanically operated channels that trigger action potential
- Action potential is an efficient signaling process by which distantly located cells communicate to each other
- Depolarization of membrane potential is due to influx of Na+ via voltage gated Na+ channels
- Fast opening of voltage gated Na+ channel shifts membrane potential from -70mV to + 50mV at which voltage gated Na+ channels become inactive thus influx of Na+ abruptly stops
Teach better , make sure we have a good understanding of things
Answer:
The producers play main role in the food chain and food web as well. These organism make food by the help of the process known as photosynthesis.
Only producers have the ability to make food by trapping sunlight. All the living source needs energy to survive.
The source of food is producers so living things cannot survive without food. So there producers are considered as the main component of food chains and food web.
hence, they play a very vital role in the environment.
Answer: Her body begins doing cellular respiration
Explanation: She needs her electron transport chain to function to produce 34+ ATP. The E.T.C. Needs oxygen to work, so she needs to increase her oxygen input. She breathes more to increase the flow of oxygen. Her heart also beats faster because she needs more oxygen to spread to her body.
