Answer:
Long protein filaments called kinetochore microtubules extended from poles on either end of the cell and attached to the kinetochores. During metaphase, the kinetochore microtubules pull the sister chromatids back and forth until they align along the equator of the cell, called the equatorial plane.
Explanation:
The answer is; Porosity which affects soil texture
The largest particle size is referred to as sand, medium is silt, while the small particles are clay. Soil texture is determined by the ratio of these three in its mixture. Soil with a higher proportion of clay becomes waterlogged easily when it rains. The right kind of soil for farming is loam because it is well drained.
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.
Tetanus
Tetanus is an acute bacterial
infection caused by the Clostridium tetani bacterium. It is
characterized by muscle spasms. The bacteria enter the body through a deep cut
or wound. The early symptoms of this infection include diarrhea, fever, and
headache. Other symptoms include sweating and rapid heartbeat.
Fern is the answer because it dosen't have seeds
