In one kilo calorie there are times kilo joules.
Mathematically, it can be written as
KCal Kilo joules
Kilo joules is equal to
kilo calories
Total energy consumed by body is equal to Kilo joules
Thus energy consumed in kilo calories is equal to
Kilo calories
Answer:
Gene therapy is an important application of biotechnology in which the mutated gene is isolated and then mutated gene is replaced by normal gene,the normal gene is integrated into a suitable vector and the vector is finally incorporated into the host which the diseased gene or matated gene is isolated.
Explanation:
Application of gene therapy
Gene therapy is used to treat various diseases such as severe combined immuno deficiency(SCID).
Benefits
Gene therapy helps to reat various life threatening diseases such as cancer,AIDS
Drawback
Gene therapy is very much expensive.
Risk
The main risk associated with gene therapy is that if the normal gene is targeted to the other part of the body instead of its original site then this can leads to mutation of another normal chromosome.
1. Fill one can with soil/sand, and fill another one can with water.
2. Get the initial temperature of the water and soil/sand. Record.
3. Place a thermometer in each set up without touching the bottom of the can.
4. Put the set-up under the sun. Take the temperature every 2 minutes for 5 times for a total of 10 min. Record your data. Since this activity requires sunlight, this should be performed on a sunny day. If the weather does not permit, use lamps. Lamps can simulate the radiation effect of sunlight.
5. After 10 min of reading, remove the set-up under the sun for cooling process.
6. Have the last temperature results of water and last temperature result for soil as the initial temperature for cooling the water and soil.
7. Take the temperature every 2 minutes for 5 times for a total of 10 min.
8. Reminder: you have to be careful in getting your data, you should follow the procedure carefully to get a reliable data, and the bulb of the thermometer should not touch the bottom of the container.
