We could use up all of them right away and not have the resources for humans and animals to survive.

Explanation:

Right now, we are using our natural resources at a consistent rate. We sometimes use to many of them in one day. If we continue using up our natural resources at the rate we are right now. We may not have the necessary resources to survive in about 10-20 years.

Which factor might an editor consider when trying to judge the validity of a scientific report submitted for publication?
Vedmedyk [2.9K]

Answer:

<em>The correct options are</em>

<em> B)  If the sources used are peer reviewed</em>

<em>D) If the writing is based on sound evidence</em>

Explanation:

To check whether a scientific report is valid or not, one must determine whether the results deduced from its experiments were accurate and true or not. If the writing provides sound evidence for its experiments to be true and not biased, then the editor will most likely publish it. A report that is supported by peer reviews will be the best to publish as the data in it will be considered to be more authentic and accurate. Hence, option B and D will be true.

Neurotransmitters categorized as inhibitory are expected to _______. A. act independently of their receptor proteins B. close po
Ksenya-84 [330]

The correct option is D.

Neurotransmitters categorized as inhibitory are expected to hyperpolarize the membrane.

At inhibitory synapses, release of neurotransmitters causes inhibitory postsynaptic potentials or IPSP, which is a hyperpolarization of the presynaptic membrane.

Actually, depolarization and hyperpolarization occurs on neuron when an ion channel in the membrane open or close which can alter the ability of certain types of ions which enter from or exit out of the cell.

Neurotransmitters which is inhibitory have inhibitory effects on the neuron as it means they can decrease the possibility that the neuron will tend to fire an action. Modulatory neurotransmitters can also affect various neurons at the same time which results in the influencing effects of other chemical messengers.

Inhibitory neurotransmitter somehow decreases the action potential of the neuron. When the action potential falls below a certain level which is called threshold potential, the neuron will not be able to generate action potentials and thereby unable to exit the nearest neurons.

So, neurotransmitters are in general expected to hyperpolarize the membrane in some extent.
