Ethylene is an organic compound produced by ripening fruits. In a controlled experiment, researchers found that ethylene gas stimulated the ripening process in newly harvested fruits. What describes the most likely connection between natural ethylene production and fruit ripening?

Explanation:

Ethylene is a chemical signal through which ripening fruits trigger the ripening process in fruits, Studies on components of ethylene signaling have shown a linear transduction pathway leading to the activation of ethylene response factors. However, the whole pathway by which ethylene selects the ripening-related genes and interacts with other signaling pathways to regulate the ripening process still not yet fully known. Most fruits produce ethylene that starts the ripening process. Its level in under-ripe fruit is very low, but as fruit develop, the production of ethylene become larger that speed up the ripening process of fruit.

answer: zinc is the substance which has a volume of 1.38 .

density is defined as the mass of an object per unit volume.

it can be calculated by dividing mass of a substance by its volume i.e.

si unit of density is kg per cubic meter and cgs unit of the same is gram per cubic centimeter.

now from the given data volume can be calculated by the formula .

hence, the volume of aluminium will be = which comes out to be 1.703 .

similarly, volume of zinc, chromium, and nickel will be 1.378 , 0.869 , and 0.356 respectively.
