Answer:Caused by differences in the atmospheric pressure.
Explanation:
Answer:
(2) low power: 100 small pollen grains
high power: 25 large pollen grains
Explanation:
Compound light microscopes are devices used to greatly magnify objects. They have several objective lenses, a low-power lens magnifies 10 times (10X) the objects, and the high-power lens magnifies them 40 times (40X).
For that reason, when observing the pollen grains with the high-power lens the student will see them bigger than with the low-power lens. However, the field of view (the visible area through a lens) is reduced when a higher power lens is used, so fewer pollen grains will be seen.
The answer therefore is the option of higher number of pollen grains of small size for the low-power lens, and lower number of pollen grains of larger size for the high-power lens.
It happens through 3 stages
- Interphase
- Meiosis 1
- Meiosis 2
In Meiosis one the cell produces diploid daughter cells by combining homogeneous and heterogeneous chromosomes.
In Meiosis two these diploids again tear apart to produce haploid daughter cells
Pleomorphism (microbiology): the ability of some bacteria to alter their shape or size in response to environmental conditions. Dedifferentiated liposarcoma is the least common subtype of liposarcoma and usually arises from a well-differentiated liposarcoma (WDLPS). Progression occurs. in 17 % of patients when WDLPS is located in the retroperitoneum and 6% of cases when WDLPS is located in the extremities.
