Answer:
The reason why, in cold temperatures and depending on the type of fatty acids, the phospholipid bilayer is less or more fluid is due to the different molecular interactions that occur between the tails of both types of fatty acids. the unsaturated - which determines the fluidity of the cell membrane.
Explanation:
<em>Temperature and saturation of fatty acid tails</em><em> are two factors that affect the </em><em>fluidity of the phospholipid bilayer</em><em> in cell membranes.</em>
Under normal conditions, low temperatures decrease the fluidity of the phospholipid bilayer, since it decreases the kinetic energy and increases the molecular interactions, which increases the stiffness.
However, unsaturated fatty acids - those that contain double bonds in their molecules - have a configuration that allows their tails to be more separated in their arrangement in the bilayer, which avoids the increase in molecular interactions and maintains to a certain extent the membrane fluidity, despite low temperatures.
Inside a cell, numerous organelles function to remove wastes. One of the key organelles involved in digestion and waste removal is the lysosome<span>. </span>Lysosomes<span> are organelles that contain digestive enzymes. They digest excess or worn out organelles, food particles, and engulfed viruses or bacteria</span>
The answer is Sodium Fluoride
Answer:
- The geography of the continents (they fit each other, contain similar mountain ranges, etc)
- The distribution of fossils and rocks
- The locations of ancient climatic regions
Explanation:
The continental drift theory states that continents moved across geologic time, plowing through oceans and drifting to different parts of the planet. The continental drift theory is associated with Alfred Wegener, who the first in using this terminology in 1912. Some of the most important lines of evidence that support the continental drift theory are the movement of continents on tectonic plates, the presence of evolutionarily related plant and animal fossils in different continents, paleoclimate indicators (e.g., glacial striations), etc.
