Seed packets give a recommended planting depth for the enclosed seeds. the most likely reason some seeds are to be covered with only ¼ inch of soil is that the

seeds require light in order to germinate

Explanation:

The most likely reason some seeds are to be covered with only 1/4 inch of soil is that such seeds require light for germination to occur.

Some seeds require light in order to germinate and if such seeds are deeply buried in the soil, they might not germinate.

According to some research, light is needed primarily to break the (photo) dormancy of some seeds. Some other research just consider light as one of the environmental factors such as water, air, etc. needed for germination.

a neutral ph of 7 and normal organism temperature is needed for a certain enzyme to be effective.  

what would happen to the enzyme if the ph and/or temperature fluctuate greatly from the norm?  

a.the enzyme’s hydrogen bonds will break.  

b.the activation energy will increase.  

c.more product will be formed.

d.the ideal temperature and ph for the enzyme function will decrease.
