The text mentions the terms: single-celled, multicellular, eukaryote and prokaryote. Define each of these terms and give examples.
Most of the time but not always. When it doesn't, it results in a gene mutation.
Answer:
Chromosomes will be seen in the nucleus of dividing cells (during mitotic and meiotic cell divisions) because they are visible when a cell is dividing as oppose to non dividing cells. Also, all processes of cell division from prophase, metaphase, anaphase to telophase will be seen :)
The
answer is ‘they create tension by pulling toward opposite poles’. Kinetochores change
between persistent phases of movement towards the pole (poleward) or inversed
(anti-poleward), which are coupled with alternating states of kMTs (kinetochore
microtubules) depolymerization and polymerization, respectively. A low tension
at kinetochores promotes change towards kMTs depolymerization, and high tension
promotes change towards kMTs polymerization.
Positive Geotrophism is referring to the plant’s angle leading to the roots growing downward into the soil. Negative Geotrophism is referring to the plant’s leaves moving away from the earth, up towards the sun in order to receive substantial sunlight.
