Echinoderms do not spend time caring for their young ones.
They reproduce by sexual means, that is the combination of genetic materials from two separate individuals (male and female). The males provide the sperm and the females provide the eggs for reproduction. The sperms and eggs are propagated into water column, and fertilization takes place in the open water. Echinoderms commonly, leave their eggs and provide no parental care to the eggs. They don't take care of their young ones at all, however, some sea urchins incubates their eggs in special little pouches.
C. Accelerating upward
Has to do with Newtons 2nd law of motion.
F=MxA. Mass times acceleration
So acceleration upwards the scale is pushing back on your normal weight plus your mass and the acceleration rate of the elevator car.
The opposite occurs when descending.
If at a constant speed/velocity, equilibrium occurs and weight exerted by ones body stays the same.
38 ATP molecules are produced
Good luck! hope this helps (:
<span>The most frequent type of ground or surface-based temperature inversion is the one produced by terrestrial radiation usually on a clear, still night. Temperature inversion refers to the increase in temperature brought about by the rise in altitude. On the other hand, terrestrial radiation refers to the radiation naturally emitted by radioactive materials present on Earth. Among these are radon, thorium, and uranium. </span>
It was commonly understood in the past the dogs come from a lineage of wolves, but that isn't the case now. Scientists have found out that dogs and wolves come from a common ancestor about 9,000 to 36,000 years ago. This was done through extensive DNA analysis with samples that took into consideration the geographic locations of their origin and of modern isolation. This yielded a result that despite geographical difference, the dogs are more closely related than to wolves. It is now understood that the complication of the genetic relationship between the two was caused mainly by interbreeding during the course of time, but it isn't just that. Some other factors have come into play including the presence of humans.
