Answer:
All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. These smaller groups are based on more detailed similarities within each larger group.
Answer:
Wall of stomach : it has three layers of muscle instead of two. Under these muscle layers is the adventitia, layers of connective tissue continuous with the omenta. The epithelium of the stomach forms deep pits, called fundic or oxyntic glands.
wall of ileum : The wall itself is made up of folds, each of which has many tiny finger-like projections known as villi on its surface. The ileum has an extremely large surface area both for the adsorption of enzyme molecules and for the absorption of products of digestion.
Sam and Jenny ride their bikes at a constant velocity of 3 miles per hour.
Explanation:
Here we see that both of them are moving at a constant velocity which means their speed is constant and they are moving in a straight line.
Zero acceleration is implied on the bikes and the net force is BALANCED.
When forces are in balance, acceleration is zero. Velocity is constant and there is no net or unbalanced force.
Well C or A would work because both are polite so yeah
