The key difference between microspore and pollen grain is that microspore is the small spore that develops into the male gametophyte in plants while pollen grain is the small grain that contains the male gametophyte.
Answer:
By donating your organs and tissue after you die, you can save or improve as many as 75 lives. As many people are waiting for transplants
Explanation:
helping/improving lives is good
Answer and Explantion
Collect data-This should be the first step in coming up with a design of an instrument to measure a certain property. The data should comprise of the air temperatures, the wind speed values and recorded peak times for the ocean currents.
Build a prototype-This is sample equipment built from the data obtained to be used as a test instrument in predicting the catastrophic weather .The prototype is a mini design of the actual design.
Evaluate the result of their system-The results obtained from the prototype can be used for evaluation to determine the working of the designed devise. The results produced should show a connection that can be used to predict the weather according the values of temperature, wind speed and ocean current values.
Modify their design-After analyzing the results according to the parameters set for the design, the prototype can be improved to obtain a final design which will indeed produce the required results.
C. They study true movement of earthquake waves
