1) Inaddition to water, mention the other three essential factors for seed germination. 2) What is the function of water in seed germination?

3) Some seeds do not germinate even though you have obtained the essential factors mentioned above. What is the condition called?
* Give two reasons for the situation you mentioned above.

1) suitable temperature, air and oxygen

2) water soften the testa to enable both the plumule and radicle to emerge and it also allows diffusion of gases

3) Based on my opinion There is no water absent (dry cotton wool that used for germination), water is required for germination and the seed was kept in a refrigerator, thus low temperature is not suitable for germination.

Hope this helps

the transfer for conduction is the heat transfering from the liquid to the spoon

the transfer for convection is the heat rising from the liquid to the air

the transfer for radiation is the heat going through the sides of the cup and to the air

at least that is what i would do

in 1859, charles darwin set out his theory of evolution by natural selection as an explanation for adaptation and speciation. he defined natural selection as the "principle by which each slight variation [of a trait], if useful, is preserved".
