why does our nose get stuffy when we have a cold
Answer:
Due to dilation of blood vessels in the sinuses of the nose
Explanation:
Often times, we think our nose gets stuffed up due to the excess mucus in times of cold but it is not always so.
We get stuffed due to the body's homeostasis, a drive to internally control and balance the outside environment.
- During cold, blood vessels dilate so as to allow for more inflow of blood.
- Incoming blood brings in more heat to the body parts.
Answer: The answers seem correct.
1. Active transport - the process in which energy is used to move the particles of a substance against a concentration gradient from a region where they are in lower concentration to a region whey are in higher concentration.
2. The answer chosen for #2 makes sense because energy is usually needed when you putting effort into doing an activity that includes some type of force. That means ions are using energy to be moved against the concentration gradient.
3. Volume makes sense for the last question since the cells are using a space (volume) to move material in and out by diffusion. The other options besides volume are unreasonable.
