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.
(C) 40 km/s
Explanation:
Divide your km/s and your seconds.
Equation: km/s divided by seconds = acceleration
- 280 km/s divided by 7 seconds = 40 km/s acceleration

Answer: 100%
Explanation: If both guinea pigs are BB dominant, that means they don't have the recessive trait, so therefore no heterozygous guinea pigs will be created. This leaves 100% homozygous offspring.
Cell division means reproduction, and in multicellular organisms it means growth. Cell division is important to replicate new DNA so that you don't die.
