Putrescine and cadaverine are short aliphatic diamine compounds produced during the breakdown of amino acids in both living and dead organisms. What tests, including solubility, would you run in order to confirm their structure
Answer:
In order to confirm the structure of Aliphatic Diamine Compounds, you'd need to run a set of tests. They are:
A. Preliminary or Initial Tests:
I. Tests for Physical Traits: this helps to determine or establish the physical traits of the substance. Characteristics such as State of Matter (e.g. solid, liquid) color, and odor.
II. Ignition test. This involves the application of heat on a minuscule amount of the compound or substance using a metal spatula. This helps to prove whether the compound is aliphatic or aromatic. An aliphatic compound such as methylated spirit is aliphatic because it produces a luminous flame. Vegetable Oil on the other hand is aromatic because it produces a sooty flame.
B. Physical Constants
This test aims to establish the boiling and melting points of such a substance.
C. Analysis for elements present
D. Solubility tests
Explanation
Amine compounds are easily distinguishable by their odors. Amine odors have a somewhat fishy almost putrid quality.
When they are at room temperature, they are present as gases and can easily evaporate in their liquid state.
Their relative densities are lower than that of water. with the exception of aromatic amines.

Describe the differences and similarities between lecithin and cephalin. Match the words in the left column to the appropriate blanks in the sentences on the right. ResetHelp Lecithins and cephalins are both sphingolipids; they consist of glycerol with fatty acids forming bonds with the first and second groups. The third group of the forms a with phosphoric acid, which forms another bond with an amino alcohol. In lecithins, the amino alcohol is ; in cephalins, the amino alcohol is usually .
Answer:
Here, we have a composition passage and we are required to fill in the with missing words. The missing words are highlighted in bold format and underlined.
Lecithins and cephalins are both glycerophospholipids; they consist of glycerol with fatty acids forming ester bonds with the first and second hydroxyl groups. The third hydroxyl group of the glycerol forms a phosphate bond with phosphoric acid, which forms another phosphate bond with an amino alcohol. In lecithins, the amino alcohol is choline; in cephalins, the amino alcohol is usually ethanolamine.
Explanation:
Lecithin is a chemical complex composed primarily of fatty acids, glycerol, phosphoric acid, and choline. It can be present in egg yolks, soybeans, sunflower seeds, and plant seed cells and is completely normal. Soybean and sunflower lecithins contain much more important fatty acids than rapeseed lecithin, making them nutritionally more useful.
Phosphatidylethanolamine, also known as cephalin, is a phosphoglyceride that, like phosphatidylcholines and lecithins, is a component of biological membranes. A glycerol residue esterified by two fatty acids and a phosphoethanolamine residue gives rise to phosphatidylethanolamines. They're made by combining CDP-ethanolamine with diglycerides and releasing a CMP molecule. Phosphatidylcholines are formed when S-adenosylmethionine methylates the amine in ethanolamines. They're mostly found in the inner layer of plasma membranes' lipid bilayers.

The evolutionary species concept defines a species as: A. a group of populations that have shared a past and will have a shared future B. reproductively isolated populations C. smallest monophyletic taxa D. morphologically similar populations
Answer:
The correct option is A.
group of populations that have shared a past and will have a shared future
Explanation:
This is because evolutionary species concept is a concept that indicate a form of ancestry descendants or lineage of populations that descend from the same ancestors possessing similar characteristics which were inherited from the ancestry and these traits are evident in the future.
Which cause of climate change can cause the Earth to get colder? Explain how.
The tilt in the axis of the Earth is called its obliquity. This angle changes with time, and over about 41 000 years it moves from 22.1 degrees to 24.5 degrees and back again. When the angle increases the summers become warmer and the winters become colder.anation:

Explanation:
The service box is an area on the court that 1 point the person serving must stand in. the ball must land in to be a playable serve. the person returning the serve must be standing in before a server can serve
Answer:
Both players on the serving doubles team have the opportunity to serve and score points until they commit a fault *(except for the first service sequence of each new game).
The first serve of each side-out is made from the right-hand court.
If a point is scored, the server switches sides and the server initiates the next serve from the left-hand court.
As subsequent points are scored, the server continues switching back and forth until a fault is committed and the first server loses the serve.
When the first server loses the serve the partner then serves from their correct side of the court (except for the first service sequence of the game*).
The second server continues serving until his team commits a fault and loses the serve to the opposing team.
Once the service goes to the opposition (at side out), the first serve is from the right-hand court and both players on that team have the opportunity to serve and score points until their team commits two faults.
In singles the server serves from the right-hand court when his or her score is even and from the left when the score is odd.

Explanation:
[please] put these in order
Answer: The arrangements and correct order of the above described genetic and behavioural adaptations includes:
A.) Camouflage: This is a survival adaptation by which an animal blends in and is hidden in its surroundings.
B.) Mimicry: This is an organism exhibiting characteristics similar to one known to be dangerous.
C.) Tropism: This is the growth or movement of an organism ( usually plant) in response to a stimulus.
D.) Venom: This is a poison secreted by animals for either defensive or offensive purposes.
E.) Mutualism: This is the interaction of two organisms where both benefits.
F.) Commensalism: This is the interaction of two organisms where one is helped and the other is neither helped nor harmed.
Explanation:
In the study of organisms and it's environment, they are able to adapt through genetic and behavioural mechanisms. Adaptation of defined as the ability of organisms to become fitted to its environment by modifying or changing its features. These features may be structural or behavioural.
STRUCTURAL ADAPTATION: Almost every part of the body of a living organism is structurally adapted to its mode of life. They are structurally adapted for the following specific functions:
--> Escape and defence: many animals use CAMOUFLAGE to remain unnoticed by potential predators. While some others are capable of producing poisonous VENOMS which may become offensive to the predators. Also many harmless organisms may possess structural behaviours that may MIMIC dangerous organisms thereby keeping their predators at arms length.
--> obtaining food: organisms needs to possess some structural features that will enable them obtain food in their environment. This usually leads to forming various feeding relationship ( which may be MUTUALISTIC or COMMENSALISM) with one another to be able to obtain food for survival.
BEHAVIOURAL ADAPTATION: Behaviour is everything an organism does in response to changes in its environment. Plants do exhibit behavioural adaptations and a typical example is the phototrophic movement of plant shoots which is a type of TROPISM.
