3A- Negative feedback occurs when some function of the output of a system, process, or mechanism is fed back in a manner that tends to reduce the fluctuations in the output, whether caused by changes in the input or by other disturbances.
3B- Negative feedback loops are used to maintain homeostasis and achieve the set point within a system. Negative feedback loops are characterized by their ability to either increase or decrease a stimulus, inhibiting the ability of the stimulus to continue as it did prior to sensing of the receptor.
Hope I’ve helped ;)
Answer:
autosome
Explanation:
if it were on a sex chromosome then either more females would have it or more males would have but it's almost split evenly
The direction iron in ocean rocks points
The new crust, formed at constructive/divergent boundary (regarding tectonic plate movement), has band-like patterns that orient in different directions (in alignment with earth's magnetic fields) and visible on the surface. This shows that it is newly made crust made from new magma.
Explanation:
These bands are firmed when the iron minerals in magma orient themselves with the earth's magnetic field before the magma cols into rock and lock the minerals permanently in position. This magma upwells from the mantle to fill the void made when the tectonic plates are moving away from each other.
The earth's magnetic field on the other hand is dynamic. Its angle increases gradually from the true north or south and then flips orientation over several hundred years. The iron minerals therefore will align differently depending on the orientation of the earths magnetic field at the time. This is why the new crust has band-like features visible on its surface.

Warm ocean currents originate near the equator and move towards the poles or higher latitudes while cold currents originate near the poles or higher latitudes and move towards the tropics or lower latitudes. The current's direction and speed depend on the shoreline and the ocean floor.
Answer:
Nephrons in birds, mammals, and reptiles are all extremely similar, more so than other structures in the bodies of different species, solidifying the relatedness through similarity.
Explanation:
Birds can be said to have "mammal-like" nephrons from the number of loops and overall structure of their kidneys, which, although they look very different, serve the same purpose and do it in largely the same way. Reptiles also have mammal-like nephrons, and it can be assumed that this evolutionary trait was kept because the specific structure of the nephrons is generally the most efficient.
