sry i cant i to dubm need points tho
Explanation:
The answer for this one is b) Looping of DNA
Answer:
Rate = 2 cm/year
Explanation:
It is given that, a plate moves 200m in 10,000 years. We need to find its rate in cm/year.
We know that, 1 m = 100 cm
200 m = 200 × 100 cm
= 20000 cm
Its rate is given by :

So, the plate is moving at a rate of 2 cm/year.
Deforestation- It is a main cause for the destruction of many animal habitats and destroys resources needed for animals. So of the reasons it many be justified is the wood is used as a biofuel, building material and it clears space for new development. Whether it is justifiable to the extend it happens now is questionable?
Answer: Heat ---from a warmer substance to a cooler substance
Explanation: Heat can be transferred from a hotter substance to a cooler substance. This can be done through three methods;
Conduction, Convention, Radiation
Conduction- When substance is been heated movement of particles increases causing collision between hotter particles and cooler particles. This continue until the temperature is in equilibrium. Metal is a good conductor of heat.
Convention- It is often associated with liquid and gases. hotter area of liquid moves and meet with cooler liquid. The cooler liquid then takes place of the hotter liquid until equilibrium is attain. This occurs while boiling water
Radiation - It doesn't need a means of transmission. It is gotten from infared emission. Infared emission increases when temperature increases .
