What portion of a pre-mRNA molecule may be cut to be discarded?
ans:- In eukaryote cells the primary transcript (pre-mRNA) is processed. One or more sequences (introns) are cut out.
Centrioles is only found in animal cells but not in plant cells.
Answer:
For example, addition of an orange chromic acid reagent to some compounds causes the chromium reagent to change to a blue-green color (Figure 6.37a). This is considered a "positive" test result, and in this case indicates the presence of a functional group that can be oxidized (alcohol or aldehyde).
Answer:Transpiration
Explanation: water cycle is the continuous movement of water on the Earth to ensure the availability of water.water is a universal solvent that is essential for the survival of living things.water cycle ensure that clean water is available.plants require water which is gotten from the soil.water is lost from the leaves of trees through transpiration.transpiration may also occur through the lenticels and stomata of stems.
the movement of water through the plant is called transpiration pull.this is responsible for the pull of water into the leaves.it increases the absorption of minerals from the soil and also cools the plant.
This water vapour that transpire from the plant,is condense as clouds, which then falls to the Earth as rain and the water cycle continue
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's metabolic activities
