This can work by correcting the cardiac function there are four classes of this drugs such as Class I for sodium channels, Class II which are the beta blocker, Class III which are the drugs that prolong repolarization and Class IV which are the calcium channel blocker.
Answer:
Explanation:
Parenchyma
1. They have thin cell wall.
2. Their cell wall is made up of cellulose.
3. They are unspecialized tissues.
4. The are found in soft part of the plant.
5. They undergo photosynthesis and can stored the food and also play important role in gaseous exchange.
6. There are spaces between the cells.
Collecchyma.
1. They are thick cell walls.
2. Their cell walls are made up of cellulose and lectin.
3. They are specialized tissues
4. They are found in plants leaves and petioles.
5 The do not undergo photosynthesis but act to give mechanical support to plants.
6. They have little intercellular spaces.
Parenchyma and collecchyma are both tissues found in plants..
Prokaryotes and eukaryotes both have a plasma membrane, mitochondria, golgi apparatus, and endoplasmic reticulum in common. But, prokaryotes have cell walls, chloroplast, and larger vacuoles because they are plant cells and animals don't need chloroplast since they don't undergo photosynthesis and don't need to hold as much water in their vacuoles.
