NNADVOKAT [17]

Explanation:

It correctly reads;

A group of students use a device to study the energy transfer during the chemical reaction between pieces of eggshell (calcium carbon) and vinegar (acetic acid). During the experiment they use the same mass of eggshell but the concentration of the vinegar varies, (1%, 3% and 5%). Answer:

1. Explain why the energy transfer is not the same between the three tests of the experiment.

2. Describe how the device could be modified so that it can MORE ACCURATELY measure the energy transfer in each reaction.

How do the nervous system and endocrine system differ in regards to managing homeostasis?
Citrus2011 [14]
Hello friend!!
The biggest difference between the two is that the nervous system uses electrical impulses to send signals through neurons, whereas the hormonal system uses chemical messengers transported into blood plasma to target cells. 
Transmission by the nervous system is short-lived but quick, whereas transmission by the hormonal system is long-lasting but takes much longer. Hene, communication is faster when using the nervous system. 
In the nervous system, responses are localised - whereas in the hormonal system, they are widespread. Responses are often permanent in the hormonal system, but temporary and reversible in the nervous system.

Which of the following is a part of the diencephalon.
emmainna [20.7K]

Answer:

d. all of the above

Explanation:

The diencephalon is a part of the brain located inferiorly and anteriorly to the corpus callosum, part of the telencephalon, and superior to the midbrain, delimited by the latter by an imaginary line that runs from the nipple to the posterior commissure (epithalamus). The diencephalon consists of: thalamus, hypothalamus, epithalamus, metatalamus and subthalamus. For this reason, we can conclude that the correct answer to your question is "d. All of the above".

Molodets [167]

Answer:

Receptors are highly specific and only have high affinity for those ligands for whom they are specific.

Explanation:

Receptors are proteins that receive a stimulus or bind a ligand and mediate effects via receptor effector system.

Receptors are macromolecules that are highly specific.

The affinity between the ligand and the receptors is determind by the disassociation constant Kd.

The receptors produce maximun effect when an appropriate specific stimulus is present.

Different recptors types are present for different ligands.

For example, muscrinic receptors are specific for acetycholine and adrenergic receptors are specific for adrenaline/nor adrenaline.

It is important to know the specificity so that the body remains in a state of balance.
