Answer:
The plateau phase seen during the action potential of a cardiac muscle cell is due to e. opening of calcium fast channels.
Explanation:
During cardiac contraction, myocardic cells reach a phase called phase 2 in which thanks to the umbral valor that they reach on the previous phase 1, calcium fast channels that are voltage dependent are open. Those fast channels just stay open by a few decimals of seconds. When those channels of calcium are open, a lot of calcium ions get into the cell maintaining depolarization of the myocardic cells. All positive charge that posses the cell due to the previous situation, causes efflux of potassium(an ion which have also a positive charge) like a way to reach a physiologic balance.
Answer:
Competency-based education is a system where the student is assessed according to his or her skills within a subject and is not assessed with the mastery of concepts, as in traditional education. This type of education can help Shawna to learn and acquire skills because it allows her to show the areas that she has the most competence and can focus on them, with a specific pace for her, where she can identify which areas she has more ability to learn and in how much time.
It is important for Shawna to understand how she learns best, because this way she optimizes her study time, avoiding elements that she has no affinity with and that hinder her knowledge.
Explanation:
Competency-based education is a very different and innovative educational system. Unlike the conventional educational system, competency-based education allows a specific and comfortable study pace for each student to be adopted, where he / she will have the opportunity to identify the areas of study that have the most skill and competence. In this way, students will be awarded according to the domain of these competencies, and areas in which the student has not shown any competence will be discarded.
Answer:
There are three main ways of avoiding the spreading of an invasive plant species via manual control. Manual control techniques include activities such as hand-pulling, digging, flooding, mulching, burning, removal of alternate hosts and manual destruction or removal of nests, egg masses or other life stages. These techniques work best on small populations or in areas where chemicals or motorized equipment cannot be used. Manual control efforts must be persistent and several treatments may be needed to reduce or eliminate the target population. If infestations are too pervasive, manual control may become labor intensive and thus not economically feasible. Digging/Hand-pulling: Remove entire root to prevent resprouting. Usually works best with small or young plants, in sandy or loose soils, or when soils are damp. Smothering: Use mulch, black plastic, carpet, or any other impenetrable barrier to cover target plants for at least one growing season. The effectiveness of this technique can be increased by first cutting the target plants and then smothering them. If dealing with a species that produces clones, be sure to cover all stems of the species. Flooding: This is only feasible where water levels can be manipulated to completely cover cut plants for a period of time. The depth of water necessary and the amount of time cut plants should be covered will vary from species to species.
Answer:
An occupational therapist.
Explanation:
An occupational therapist is a professional that helps a person with an illness, injuries, or disabilities to have a better quality of life and to prevent any further problems. The professional, together with the patient and the patient's family, set the goals. Then the occupational therapists design a plan to help the person to achieve the settled goals and helps the patient through the process. Throughout the process, the occupational therapist makes constant evaluations to check on the progress and see if any changes in the plan are needed.
Answer:
Acute oseteomyelitis is treated with antibiotics such as gentamicin. Gentamicin use can cause ear toxicity; therefore, the client should report any hearing loss to the primary healthcare provider.
