After suffering a stroke, lulu finds she cannot move her left leg. this would suggest that the stroke damage is in the area of the Left Frontal Lobe.
What is Frontal Lobe?The frontal lobe is the largest of the four primary lobes of the brain in animals, and it is placed at the front of each cerebral hemisphere (in front of the parietal lobe and the temporal lobe). It is divided from the parietal lobe by a groove between tissues known as the central sulcus and from the temporal lobe by a deeper groove known as the lateral sulcus (Sylvian fissure). The frontal pole, one of the three poles of the cerebrum, is the most anterior rounded section of the frontal lobe (albeit it is not well-defined) .
The management of higher level executive functions as well as voluntary movement and expressive language depend on the frontal lobes.

A democracy can have both representative and direct characteristics at the same time.
Yes, democracy can have both representative and direct characteristics at the same time.
There are many both-elements democracies in the Middle and Western US states. On the one hand, they have legislatures made up of Representatives and Senators, which is obviously a representative democracy because the representatives are chosen by their constituents and serve as their representatives in the legislature. Many of these states also have the referendum and initiative processes. In places like South Dakota and Nebraska, voters can use the initiative process to collect signatures and put possible laws on the ballot; if the proposed law achieves a majority vote, it becomes a law and cannot be vetoed. This is a direct democracy since the voters are deciding whether legislation should be passed without using their representatives.

Explain how bacteria affect the water-holding and nutrient-holding capacity of soil?
Bacteria improve the nutrient holding capacity of the soil as they perform nutrient cycling as well as decomposition of dead and decaying matter that increases the nutrient richness of the soil. The water holding capacity is improved by the formation of aggregates of soil that hold the water molecules efficiently.
Nutrient cycling is the process in which a nutrient follows a specific path repeatedly and benefits the living organisms in the process. The pathway generally includes of both, the living as well as the non-living factors. The various nutrient cycles that run in the nature are: carbon cycle, sulfur cycle, nitrogen cycle, etc.
Decomposition is the process of decaying of the dead organic matter of plants or animal that results in the transfer of nutrients from the dead organic matter to the soil.

Damage to tissues can occur internally or externally. When this occurs, a series of events called tissue repair are set in motion to contain the damage and initiate the healing process. One of these processes is called regeneration.
When the body replaces damaged or dead cells using cells of the same type, it is called regeneration. This occurs in most skin injuries like cuts, minor burns or scrapes and often doesn't leave any major scar. The internal organ that regenerates outstandingly well is the liver. Since the same type of cells are used during regeneration, the normal function of the organ is restored after regeneration.
