For the generalized scheme of Alternation of generations (see p. 120), plants have two forms based on a genetic complement that are the Sporophytes (2N diploid) and Gametophyte (N haploid). The processes connecting the two stages are gametangia producing haploid spores and zygote cell growth producing haploid gametophyte. Group of answer choices
Answer:
D. The tubes allow water and nutrients to be transported throughout
the plant.
Explanation:
option D supports the description of the cells. The long , vertical tubes transport water and nutrients and are most likely xylem and phloem vessels.
option A is wrong since, chloroplasts inside the cell helps in absorbing sunlight.
option C is also wrong, because water loss is controlled by the stomata in the leaves and they are not long tubes.
option B could possibly be right but option D is better suited.
The answer is B.
Fermentation(an anaerobic process) is a way of harvesting chemical energy without using either oxygen or any electron transport chain.
Fermentation consists of glycolysis plus reaction that regenerate NAD+ by transferring electrons from NADH to pyruvate or derivatives of pyruvate.
There are many types of fermentation, lactic acid fermentation and alcohol fermentation are the most common two.
<span>When a plant undergoes photosynthesis, one of the by-products is oxygen or CO2.

SDS-PAGE electrophoresis is used to verify the purity of a protein product. Some of the limitations of this method are:
<span><span>· </span>identification of a band on a protein gel is not always reliable because different polypeptides can have very similar molecular masses,</span>
<span><span>· </span>band on a protein gel may mask the presence of more than one polypeptide,</span> <span><span>· </span><span>presence of non-protein residues can affect the mobility of polypeptide and thus cause an error.</span></span>
