Depending on the learning aspect it may be better to study on the key points. Make small reminders or ways to remember them. ( Ex. Navigational points - North East South West, clockwise. Ned Eats So much Weed. Kid friendly, Ned Eats So many Watermelons ) 
As well as the topics in the beginning of the year may be useful to have as they contain the foundation of information needed. If you need to, create a few notes about each topic and go through them, so it'll be easier to remember when you take your test.

Plants inherit genes that enable them to produce chlorophyll, but this pigment is not produced unless the plants are exposed to light. this is an example of how the environment can influence on gene expression.  
<span>
Light has an important role in gene expression in plants by producing a number of light-induced changes. One of the examples of the light effects is that chlorophyll and the proteins required for assembling the photosynthetic apparatus are synthesized together with the enzymes needed for carbon fixation. Gene expression influenced by light includes the regulation at the level of transcription or, alternatively regulation of translation.</span>

Alisiya [41]

They are rich in hydrogen and helium, they have unlimited supply of hydrogen, they have a strong gravitational pull.

Explanation:

Space where huge size of gaseous and dust cloud is present is called nebula. It is mainly made of hydrogen and helium. Nebula exist in the space which is between the stars and it is call as interstellar space.

Helix nebula is closest nebula which is near the earth. It’s distance from earth is about 700 light years.

Dark nebulae are very dense as well as cold. Nebula can be divided into dark nebula and bright nebula. The gas which is present between the stars is always combine with solid grains cosmic dust.
