Answer:
Alternation of generations in plants permits both mitosis and meiosis but at different stages.

The correct answer is - That some force lifted the rocks from the water.
The fact that there's sedimentary rocks on the tops of the mountains is an evidence that there has been some force that managed to lift upwards parts of the seafloor. Taking into consideration how slowly this force manages to lift up parts of the Earth, we can easily assume that the Earth is very old. The amount of time that is needed for a part of the seafloor to be lifted few thousand meters upwards is counted in tens of millions of years, thus giving us evidence that the Earth has been around for a very long time.
Answer:
Plants
Explanation:
They are multicellular organisms. In plants there are two types of reproduction :- sexual and asexual. Sexual reproduction happens when androecium and gynoecium both fuses and in asexual reproduction when only androecium or gynoecium is present in a plant. Androecium us a male part off flower and gynoecium is the female part of flower. Plants can't move that we all know and they are autotrophs coz they can make their own food in presence of sunlight, water, air and chlorophyll.....
I hope u will understand it :-) :-)
