The wood in a matchstick is made of cellulose, a polymer of glucose molecules. When you light the matchstick, heat and light are given off, indicating that an exothermic reaction is occurring.
There are two types of reactions:
1. Exothermic reactions: In these reactions, the reactants combine to form product and heat is liberated. Example, burning of fuel.
2.Endothermic reactions: In these reactions, the reactants combine to form product and heat gets absorbed from the surroundings. Example, photosynthesis in plants where the energy of the Sun gets absorbed.
Fill a graduated cylinder to 10mL, place the rock inside and calculate the difference in mL.
The heat can cause the killing of the bacteria. It is estimated that all the pathogenic bacteria are killed after a heating of 70-75 degree Celsius or 165 degree Fahrenheit.
The ground meat or poultry can be infected from many type of bacteria, which are present in atmosphere or in the body of the organism, whose meat is being consumed.
So, in order to kill the pathogenic bacteria, the cooking at 165 degree Fahrenheit or above for sometime must be done
So, the given blank can be filled with 165.
Answer:
Parasitic
Explanation:
The plants that are described are typical example of parasitic plants. These types of plants have a parasitic relationship with the other plants, at least with the ones that they can use. In order for them to grow, survive, and prosper, these plants need a host plant. They attach to the host plant's steam with their miniature claw like organs, and use them for support to grow upwards, but also to extract nutrients from the host plant. While this leads to to parasitic plant's survival and prospering, the host plant is suffering, and gradually the parasitic plant will suck every nutrient out of the host plant and kill it. Without a host plant, these plants would find it extremely hard to survive, and the chances are very high that they will die because they are not well suited to get nutrient on their own.
When you want to either touch something to figure out whether or not it might be harmful or not. And we also use our sense of touch when we might be looking for an object, when you touch the object immediately your brain knows what it is.
