Answer:
The correct answer will be option-pollen.
Explanation:
The pollen are the male gametophyte which is produced in the seed plants.
The pollen produce male gametes after entering the female gametophyte. The male gametes fuse with the egg cell and form the embryo inside ovary which matures and forms seeds. The vascular seed plants lack these pollen but instead produces male gametes in gametangia which are replaced by the pollen in the seed plants.
Thus, option-pollen is the correct answer.
<span>A centimeter is 100 times smaller than one meter (so 1 meter = 100 centimeters). A dekaliter is 10 times larger than one liter
(so 1 dekaliter = 10 liters). Here is a similar table that just shows
the metric units of measurement for mass, along with their size relative
to 1 gram (the base unit).</span>
Phenotype <span>refers to physical characteristics that are studied in genetics.</span>
Because this new life form has no nuclei, the only kingdoms it could belong to are <span>eubacteria or archaebacteria.</span>
The possible reason for this condition is Staphylococcus
aureus. Staphylococcus aureus causes over 50% of bone infections. Other
organisms include Proteus vulgaris and Pseudomonas aeruginosa, as well as E.
coli. The Treatment of acute osteomyelitis
includes large doses of I.V. antibiotics (after blood cultures identify the
infecting organism). Surgical drainage may be indicated, and the affected bone
is immobilized. The client usually requires I.V. fluids to maintain hydration,
but oral intake isn't necessarily prohibited.
