<u>Answer:</u>
Mitochondria, the organelles involved in cellular respiration, can also generate chemicals called reactive oxygen species (ROSs). ROSs can damage mitochondria. Damaged mitochondria generate more ROSs than healthy mitochondria. This is an example of a positive feedback mechanism
The reactive oxygen species that are given out by the mitochondria during cellular respiration are the major cause of aging. Though this has a lot of negative effects but this also has a small amount of positive effects such as the start of angiogenesis or cell proliferation.
Simple but very simple question. Cellulose.
When the nurse has observed of a patient who runs a ventricular
tachycardia, it would likely show that their no presence of P waves, there is a
wide QRS complex in the monitor and the rate would range between 100 to 250, if
all manifest this in the monitor, it is likely that the patient has ventricular
tachycardia. The medication that the nurse should give to the client who has
exhibit this should have an anti-dysrhythmic drugs, that is important in the
first line of treatment. Drugs of these kind include, lidocaine, procainamide
and even amiodarone. If there is a need to correct the rhythm, it is likely
that cardioversion is given as a treatment.
Answer:
Temperature changes can also contribute to mechanical weathering in a process called thermal stress. Changes in temperature cause rock to expand (with heat) and contract (with cold). As this happens over and over again, the structure of the rock weakens.
Explanation:
The carbon cycles recycles caronatoms(carbon dioxide) and the nitrogen cycle recycles nitrogen.and the carbon cycle makes carbon dioxide and the carbon dioxide goes to the trees ,and the trees get the nitrogen and starts the cycle again.
