Answer:
Both ferns and flowering plants produce spores at some point in their life cycles. True
Only ferns have a gametophyte as part of their life cycle. False.
Only flowering plants produce pollen grains. true
Both a tree and a large fern plant are diploid sporophytes. True
Explanation:
Yes, both ferns and flowering plants produce spores in their life cycles. In fern plant, it produce spores on the underside of the leaves whereas in flowering plant, there are two types of spores such as microspores and megaspores. Both ferns and flowering plants have gametophyte as part of their life cycle. Flowering plants produce pollen grains whereas non-flowering plants produce spores to continue their generation. Both tree and large fern plants having diploid sporophytes which is a necessary part of their life cycle.

Answer:
I think is D because I had this question
Answer:
This means that the means height (which is all the sum of the height of all the students divided by their number ) is 205 cm. Standard deviation means how the height of the students deviates from this mean since students do vary in height and are not all the same height of 205 cm. Therefore, in this case, the amount of standard dispersion of the students' height is by 17 cm on either lower or higher side of the mean.
One of the reasons why the fish population remains approximately the same from one generation to the next is because not all the eggs laid will survive to adulthood. There are several factors which bring about elimination of the the newly hatched eggs. Examples of these are predators and diseases which eliminate the young offsprings at different stages before they develop into adulthood.
Secondly, production of many eggs by the different fish species leads to competition for survival. Resources such as water, food, oxygen and shelter have to be fought for and its only the fittests that will be able to survive till the reproduction stage.
