Answer:

Explanation:

the first law is the law of conservation of energy which basically means energy can't be created or destroyed in an isolated system.

What are the primary atoms that make up the scents that we smell? 2. is scent subjective? why or why not? 3. what are the two di
aleksandrvk [35]

Answer: seen below

Explanation:

1) The olfactory receptor can recognize and respond to different ordor, For humans, most odorant molecules are made up of combinations of 5 kinds of atoms: these are, carbon, hydrogen, oxygen, nitrogen, and sulfur.

2) yes, scent is subjective. This is because there is likely variation in people's sensitivity to odor or personal appreciation of different odors. Not everyone smells the same thing.

3) The two proposed theories for the mechanics of scent recognition are; vibration theory and shape theory which is also called the lock and key model. The main problem with one of Turin theories is that we can't currently predict odor character from vibration any better than we can from shape. That is we are still terrible at predicting ordor character from molecular structure.

4) Science has contributed to the creation of scented products and perfumes by having chemical Mixtures Tested in labs and addition of substances for smell.

5) Scents or fragrances are used in cosmetology as perfumes, lotions, shampoos, face washes, body cream, conditioners, etc. Cosmetologist need to be aware of scents and fragrances because if a perfume had a scent that did not smell right then no one would want to purchase their product.

Social cognitive theory proposes that changing a behavior is a function of individual characteristics. True or False
sertanlavr [38]

Answer:

The answer is: False.

Explanation:

Social cognitive theory stands that portions of an individual's knowledge acquisition can be related to <em>observing others within the context of social interactions. </em>

When people observe a model performing a behaviour and the consequences of that behaviour, they remember the sequence of events and <em>use this information to guide subsequent behaviors</em>.

The theory says that people do not leatn new behaviours solely by trrying them and either succeding or failing, but upon the replication of the action of others.

I hope it works!

List the 3 types of cell junctions and state which is the most and least permeable.
Zanzabum
1) occluding junctions
2) anchoring junctions
3) communicating junctions
Occluding junctions do not totally seal the space between cells and the resulting permeability varies greatly.  I would say anchoring junctions are most likely with one of the other 2 junctions being least permeable.

In the ED, blood is withdrawn from the vein and into a test tube. The packed cell volume (RBCs) is 1.45 ml, and the plasma volum
Yuri [45]

Answer:

<h2>1.45 + 3.55 = 5.0 (total blood volume);  1.45/5.0 × 100 = 29% (low),</h2>

Explanation:

HCT is calculated as:

HCT = Volume of red blood cells / (Volume of red blood cells + volume of plasma) x 100  

1.45 + 3.55 = 5.0 (total blood volume);  1.45/5.0 × 100 = 29% (low), normal range for an adult female HCT  ranges from 38 to 46% (some sources claim 34.9-44.5%).

*for calculating this, one must know two of these three values: packed cell volume, total blood volume, plasma volume.

Total blood volume = Packed cell volume + plasma volume.
