Q:

The difference between the time taken by two trains to travel a distance of 350 km is 2 hours 20 minutes. If the difference between their speeds is 5 km/hr, what is the speed of faster train ?

A) 36 kmph B) 30 kmph
C) 34 kmph D) 40 kmph
 
Answer & Explanation Answer: B) 30 kmph

Explanation:

Let the speed of the faster train be 'S' kmph

 

Then speed of the slower train will be '(S-5)' kmph

 

Time taken by faster train = 350/S hrs

 

Time taken by slower train = 350/(S-5) hrs

 350s-5 - 350s = 2 hrs 20 min = 213 = 73

 

=> S = 30 km/hr.

Q:

Pollination is best defined as

A) growth of pollen tube in ovule B) visiting flowers by insects
C) germination of pollen grains D) transfer of pollen from anther to stigma
 
Answer & Explanation Answer: D) transfer of pollen from anther to stigma

Explanation:

Pollination is when pollen grains from an anther, the male portion of a flower, are transferred to a female part of the flower, known as the stigma. In order for pollination to be successful, the pollen grains transferred must be from a flower of the same species.

 

After the pollen grains land on the stigma, they create a pollen tube through the length of the style or stalk connecting the stigma and ovary. Once the pollen tube is complete, the pollen grain will send sperm cells from the grain down to the ovary. When the sperm cells reach the ovary and the egg cells, fertilization will occur, which will result in the formation of the seed. The seed will then be released from the parent plant and will be able to grow into a plant and continue the reproductive cycle using the method of pollination.
