Answer:
Chemical nutrients and energy tend to flow in the same direction for most of an ecosystem. The big difference is that the chemical nutrients are ultimately recycled in the ecosystem while the energy is ultimately lost from the ecosystem to the universe at large. Energy in any ecosystem ultimately comes from the Sun
Explanation:
D) All of these
Reason: All of these could be used as an alternative energy resource to help minimize air
pollution in this community.
Solar energy can be captured with solar panels and used to produce electrical energy or
to heat systems directly. Wind energy can be captured using wind turbines, which turn
generators to produce electricity. Hydroelectric energy can be produced by using the
energy of running water to turn generators.
Although all types of alternative energy resources have various advantages and
disadvantages, these three all share the advantage of not producing air pollution
Hope this helped. :)
Clearing land is not a sustainable practice in any form, so not A. Crop rotation is important for maintaining soil fertility, but is not necessarily sustainable. It's definitely not C. It is likely D because using only renewable resources is top notch sustainability.
Answer:
The correct answer is a. can be activated by the release of epinephrine.
Explanation:
Epinephrine is a hormone and neurotransmitter naturally secreted by the body through the adrenal glands, synthesized and stored in the adrenal medulla and released into the systemic circulation. Epinephrine is a non-selective adrenergic agonist, stimulating alpha1-, alpha2, beta1, and beta2-adrenergic receptors. The systemic actions of catecholamines are mediated by the binding of these compounds to plasma membrane receptors, of the GPCR type widely distributed throughout the body and known as adrenergic receptors, which are activated by the catecholamines adrenaline (epinephrine) and noradrenaline . These receptors cause different effects depending on the G protein subtypes to which they are associated and the signal transduction mechanism linked to the specific G protein.
So to solve this problem, we are going to have to set up a couple unit conversions and then cancel units:
This method can be used to convert between many different units and is a very helpful tool for questions such as these.
