I believe the correct answer is homeostasis.
Hi!
The answer would be B. Positive
Explanation:
A positive feedback mechanism is that in which a stimulus induces an output which in turn functions to magnify the same response <em>(acting as a stimulus to itself). </em>
As in this case, Ethylene acts as a stimulus for fruit ripening (<u>response</u>). When it is released during fruit ripening, it stimulates nearby fruits to ripen (<u>response</u>), which in turn acts to stimulate further fruits to ripen (<u>response</u>), resulting in the effect being widespread (<u>magnified</u>)
Hope this helps!
1- When sunlight hits the earth at an angle, like near the north or south poles, it causes the radiation to be spread out over a larger area, than when the sun hits at a 90 degree angle, like at the equator. Therefore, it is hotter in the areas where the solar radiation is more heavily concentrated.
2- Seasons are when the earth's rotational axis tilts towards or away from the sun. It is tilted at an angle of 23.5 degrees, in relationship to the sun. The part of the earth tilted TOWARDS the sun is the area currently in summer. The area tilted AWAY from the sun is the area in winter.
3-This is basically what I already said. The area that is currently summer, is the part of earth tilted towards the sun. The area where it's winter is the part tilted away. And then obviously, spring and fall, are on the sides that are perpendicular to the sun. Hope that helps! If so, please mark Brainliest!
Paleontology, the study of fossils, supports evolution because the discovery of old life forms shows how new life evolved.
Photosynthesis:
H2O + Co2 + atp = O2 + glucose
Is that what you were looking for?
