Because it's seen as unfair. A carbon tax is regressive. By making fossil fuels more expensive, it imposes a harsher burden on those with low incomes. They will pay a higher percentage of their income for necessities like gasoline, electricity, and food.
Answer:
Negative feedback loop
Explanation:
When the blood calcium level is low, the receptors of the parathyroid gland sense it and increase the production of cAMP. The increased cAMP levels stimulate the secretion and release of parathyroid hormone from the parathyroid gland into the blood.
The increased parathyroid hormone levels stimulate the number and activity of osteoclasts and speed up the process of bone resorption resulting in the release of calcium ions from bone into the blood to raise the blood calcium levels.
Here, the response (increased blood calcium level) reverse the stimulate and hence, the process is under the regulation of negative feedback loop
.
Only eukaryotes use mitosis, these cells have a single nucleus and membrane-bound organelles.
Eukaryotes have their DNA inside a nucleus while Prokaryotes just have it floating inside themselves
A limiting factor. I remember getting this answer right on a test.
