What drives motility in sporozoa?
muminat

Sporozoa are non motile organisms.

<h3>What do you mean by sporozoa and why they are non motile?</h3>

Sporozoa are  parasitic non motile protozoa that  have a complex life cycle usually involving both sexual and asexual generation often in different hosts and includes important pathogens. Sporozoans do not have flagella or cillia for locomotion . They depend on twisting and bending on move.

Sporozoa do not have flagella or cillia for locomotion. So, they are non motile .

Are the anomalies the same thickness along all ridge segments Why or why not?<br> plz help :D
trasher [3.6K]

Answer:

The equivalent magnetization (EM) and mantle Bouguer anomaly (MBA) were calculated along the ultraslow-spreading Mohns Ridge axis in the Norwegian-Greenland Sea. The magnetic anomaly and the associated EM were compared with the bathymetry, MBA, seismically determined crustal structure and geochemical data at both the inter-segment scale (>60 km) and the intra-segment scale (20–60 km). At the inter-segment scale, the magnetic highs at the segment centers are independent of the MBA. Of the 13 segments, 9 with magnetic anomalies >700 nT coincide with axial volcanic ridges identified from multibeam bathymetry maps, which suggests that the magnetic highs at the segment centers may be more associated with the extrusive lavas rather than the amount of magma supply. With few exceptions, the magnetic anomaly lows associated with MBA highs at the segment ends increase from south to north. This trend might be explained by thickened extrusive basalts and/or more serpentinized peridotites at the segment ends in the north. At the intra-segment scale, the most prominent features are the decreases in the magnetic anomalies and associated EMs from the segment centers to the ends. The intra-segment magnetic anomalies have positive and negative correlations with the bathymetry and MBA, respectively. The magnetic signal modeled by the seismically determined layer 2A with an assumed constant magnetization is remarkably consistent with the observed magnetic anomaly, which strongly suggests that the thickness of the extrusive basalts dominates the magnetic structure in each segment along the Mohns Ridge. In general, the thickness of the extrusive basalts dominates the magnetic structure along the Mohns Ridge, whereas the contributions from serpentinized peridotites may be significant at the segment ends and may produce long-wavelength magnetic variations. The magnetic data can be used as an indicator of the thickness of the extrusive basalts within segments along the ultraslow-spreading Mohns Ridge.

Explain why a controlled (scheduled) cell cycle is essential to life
nika2105 [10]

Answer:

Control of the cell cycle is necessary for different reasons. When the cell cycle are not regulated, cells could constantly undergo cell division without any form of control which will lead to cancer.

Internal regulation of the cell cycle is necessary to alert the passage of one phase to the next at a set given time. This helps in the overall metabolism of the body.
