Chemistry

dlinn [17]1 year ago

The question requires us to complete the sentences regarding characteristics and properties of lipids.

First, we need to keep in mind what are lipids: these essential molecules to cell's membranes are typically made of a glycerol backbone, fatty acid "tails" (the hydrofobic part) and and a phosphate group (a hydrophilic part). The term "lipids" is commonly used as a synonym for "fats", which it isn't completely wrong as they share many properties (for example, lipids don't mix with water).

As they are organic molecules, all lipids have carbon, oxygen and hydrogen in their structure, while some of them can contain other elements (such as phosphorus for the phospate group and nitrogen).

<em>Considering the information above, we can complete the sentences as:</em>

<em>1. "Lipids is a general term describing organic molecules that are </em>insoluble<em> in water".</em>

<em>2. "</em>All<em> lipids are made of carbon, hydrogen and oxygen, while </em>some<em> lipids contain other elements..."</em>

Stimuli for various sensations are received for the first time by the senses, which make up the sensory system, which is the set of organs such as:

  • eyes
  • tongue
  • nose
  • ear
  • skin

that capture the chemical and physical stimuli and sensations of our body and the environment, transmitting them in the form of electrical stimuli to the central nervous system, which processes them and translates them into sensations and responses.

An example of a contact external sense is sight and taste, such as our eyes that are capable of reproducing images external to us that are not produced internally, such as hunger and common sense.
