Answer:
The size up of a motor unit varies from<u> just a few fibers</u> in the precise muscles to over a <u>thousand</u> fibers in the powerful muscles
Explanation:
A motor unit can be defined as a single motor neuron comprising all the muscle fibers that are stimulated by that neuron. Hence, when a motor neuron fires an electrical impulse, all the muscle fibers attached to that unit are contracted simultaneously. This motor unit can be smaller in size such as few neuron fibers to eyes for producing precise eye movement. On the other hand, these neurons can be delivering strong impulses to thousands of neuron fibers such as to leg muscles for producing powerful contractions.
Answer:
Cindys physician is interested in her white blood cell count more particularly her T cells as they are known as killer cells as well as memory cells. These killer cells active in search of host cells aka "viruses". If the T cell has no memory of the host it will not be fought off as quickly. However since viruses are always adapting it is a constant battle. Furthermore since HIV stands for human immunodeficiency virus, it is important to known whether she has a high or low count. Considering she has HIV it can be projected her count to be below average which is 4,000 and 11,000 per microliter of blood. Below 4,000 can lead to low immunity, which in turn means a higher risk of catching viruses such as colds or in this case HIV.

Bloodstains are classified into three basic types: passive stains, transfer stains and projected or impact stains. Passive stains include drops, flows and pools, and typically result from gravity acting on an injured body. Transfer stains result from objects coming into contact with existing bloodstains and leaving wipes, swipes or pattern transfers behind such as a bloody shoe print or a smear from a body being dragged. Impact stains result from blood projecting through the air and are usually seen as spatter, but may also include gushes, splashes and arterial spurts. Blood spatter is categorized as impact spatter (created when a force is applied to a liquid blood source) or projection spatter (caused by arterial spurting, expirated spray or spatter cast off an object). The characteristics of blood spatter depend on the speed at which the blood leaves the body and the type of force applied to the blood source.
