Answer:
B) After determining the optimum pH, they could vary the temperature of the environment to see if catalyses is temperature specific.
Bloodstain shape is determined by the angle between the flight path of the droplet and the surface that it impacts (Fig.1). When a drop of blood strikes a horizontal surface from the perpendicular (at an angle of 90°, Fig.2), the resulting bloodstain will be round. As the angle between the blood drops’ flight path and the target surface decreases, the length of the resulting bloodstain increases and the width decreases; in other words, the bloodstain becomes longer and narrower as the size of the angle decreases (Fig.3). A blood drop that has impacted a target surface from an angle of 12° will be long and narrow (Fig.4). Also present on these long, narrow stains is a ‘tail’ (Fig. 4). As the drop of blood impacts the target surface, the main body of the droplet will stick to the surface. A small portion of the blood drop will tear off from the top and continue in a forward direction. This secondary spatter has the appearance of a tail.
Answer:
What is a theory?
When hypothesis has been tested and found to be repeatedly correct within the limits of available evidence, it becomes a theory. Usually, a theory incorporates a number of verified hypothesis.
If a theory has been extensively tested and proven to be true, it becomes a law or principle. A law or principle must also hold up to New discoveries, improved technology and continual experimentation.

Answer:
PICC lines are appropriate for long-term therapy and can easily be used in the home environment.
Explanation:
The most appropriate type of IV access for Elaine is a PICC line because the practitioner recommended home IV therapy for two weeks. These lines are actually the most appropriate because they can be used in places such as home environment and for long-term therapy.
A PICC line is a long, thin, flexible tube called a catheter. It is used to give you chemotherapy and other medicines. A doctor or nurse puts it into a vein above the bend of your elbow. It can stay in place until your treatment is over.

In aerobic respiration, the final electron acceptor in the electron transport chain is oxygen. It accepts two electrons and a molecule of water is formed as a by product.
In anaerobic respiration, the final electron acceptor in the electron transport chain is pyruvate. Anaerobic respiration commonly occurs in the muscle tissue of animals as a result of intense activity or exertion. Pyruvate is used as makeshift electron acceptor in place of oxygen and is reduced or converted to lactic acid.
