In 2010, global greenhouse gas emissions from the agricultural sector totaled 4.7 billion tons of carbon dioxide (CO₂) equivalent, up 13 percent over 1990. Agriculture is the third largest contributor to global emissions by sector, following the burning of fossil fuels for power and heat, and transportation.May 8, 2013

Carbon dioxide accounts for most of the nation's emissions and most of the increase since 1990. Electricity generation is the largest source of greenhouse gas emissions in the United States, followed by transportation.

Is a microvilli is a tiny finger like projection that kills bacteria in the lymphatic system? true or false
Alika [10]

Villi are tiny finger like projections present in the inner epithelial lining of the intestine. Each finger like villi is further divided into microvilli, which is the extension of plasma membrane of each epithelial cell of the villi. These villi and microvilli present on the inner surface of the intestine provide a greater surface area and this enhances the digestion and absorption of the nutrients.

Therefore, the correct answer is false as a microvilli is the tiny finger like projection of the inner epithelial cells of the small intestine that has absorptive functions.

Heat that flows by conduction is the transfer of thermal energy between substances in contact. What must occur for this
Lady bird [3.3K]

Heat flow by conduction requires that the two systems must not be touching each another.

<h3>What is heat energy?</h3>

Heat energy is a form of energy that exists due to a temperature difference between two objects.

Heat energy flows from an object at higher temperature to an object at a lower temperature.

Heat transfer by conduction involves the vibration of particles of the medium transferring heat due to contact between the two objects.

Therefore, heat flow by conduction requires that the two systems must not be touching each another.
