The correct answer is option (A) Variation in the strawberry plants.
When the effect of fertilizer on the growth of two strawberry plants is tested, unavoidable source of experimental error is the variation in the strawberry plants. Variation refers to the deviation or differences from the normal plant which can be due to genetic variation. It is due to change in the DNA sequence. If any one of the two plants being tested show variation, the rate of metabolism differs and changes the growth pattern of the plant. The rate of absorption of water and nutrients is effected which brings change in the growth of the plant and causes an error in the experiment and the result.
almost all weather occurs in are troposphere
First off, we need to understand that osmosis is typically used with the example of water---
To understand that, osmosis is taking water from a high concentration to a low concentration to make the membrane equal to one another .
Imagine you have a pea, and the pea is about to explode of water. And you have another pea that's shriveled up. You would take some of the exploding water's pea into the shriveled one, therefore making it equal. (Thats my example I like to use!)
I hope this helped!
Answer:
Tropical Zone
Explanation: Its near the equator with warm air masses with the average temperature in the coldest month is 18 °C. This is warmer than the average temperature of the warmest month in the polar zone.
I guess I would say b or d. Because concluded results change over time with better technology and some solutions dont work.
