Capsule is a structure present in prokaryotes but absent in eukaryotes.
<h3>What are prokaryotes? </h3>
Prokaryotes cells are cells that do not have structures bounded in a membrane. example include bacteria.
<h3>What are Eukaryotes?</h3>
Eukaryotes cells are organisms that have their nucleus and other organelles bounded in an enclosed membrane.
Prokayote e.g Some bacteria have capsules it is carbohydrates in nature and it enables the bacteria to attach themselves to the surface. This is not present in eukaryote cells.
Conclusively, Capsule is the structure present in prokaryotes but absent in eukaryotes.

Answer:
E. juxtaglomerular complex
Explanation:
Macula densa cells are the columnar tubule cells. They are present in the wall of afferent arterioles. The modified fibers of smooth muscles present in the lining of the afferent arteriole are called juxtaglomerular cells.
The juxtaglomerular cells and macula densa cells together make the juxtaglomerular apparatus, also called juxtaglomerular complex. The function of the juxtaglomerular apparatus is to maintain the blood pressure of kidneys.

Answer:
3. a leaf falling off of a tree to the ground.
Explanation:
Force is given by the multiplication of mass and acceleration.
Mathematically, Force is;
Where;
- F represents force measured in Newton.
- m represents the mass of an object measured in kilograms.
- a represents acceleration measured in meters per seconds square.
Force can be categorized into two (2) main types; forces that at a distance and forces the act by direct contact with the body.
A force that acts at a distance refers to the force exerted on a body or an object without any physical contact between them such as gravitational force, magnetic force and electric force. This simply means that, there can be a push or pull between objects even when they are not in physical contact with each other due to gravitational, magnetic or electric forces.
<em>Some example of a force that acts at a distance is a leaf falling off of a tree to the ground, a magnet pulling an object to itself, a magnet pushing or repelling another magnet etc. </em>
