Answer:

Gaseous exchange between leaves and atmosphere would be disturbed due to blocked stomata.

Explanation:

Leaves have stomata on their surfaces. Through stomata, plants take the oxygen in for respiration. Carbon dioxide gas is also released into the atmosphere through stomata. Similarly, plants take the atmospheric CO2 through stomata to perform the process of photosynthesis. The molecular oxygen produced as a by-product during photosynthesis is also released through stomata.

Coating both sides of leaves with petroleum jelly or wax would block stomata. Leaves of the plant with coating would not be able to perform breathing and photosynthesis.

Biomass is the most used renewable source of energy in US in the year of 2009.

<h3><u>Explanation:</u></h3>

In US, the country is very cold and use of wood and other plant products as chimney fuels, or in cooking and other purposes are very common. This is because being a temperate country, US has forests of conifers which are source of soft wood, ideal for burning.

Other sources of Biomass energy comes from the biogas, wood wastes, ethanol, municipal solid wastes and even biodiesel.

As a present day scenario, although coal and petroleum are still the most used fuels in US, but the use of renewable sources of energy has increased to twice the amount from 2010 to 2018.
