Answer:

Heat and pressure build up on top of decaying matter was necessary for the formation of all fossil fuels.

Explanation:

Fossil fuels are different energy sources in the form of hydrocarbons, which come from older geological periods, and which can be found on or below the ground in the litho and pedosphere. According to the biogenic theory, which prevails today, the fossil fuels are the remains of ancient animals and plants that have been buried in the earth and then decomposed under high pressure and heat to their constituents (mainly carbon and carbon compounds).

The fossil fuels mainly comprise natural gas, petroleum and coal. Natural gas consists mainly of the gas methane and has a high content of the element hydrogen compared to the element carbon. Methane is found in natural gas fields together with crude oil or bound as methane clathrate. Petroleum (also called crude oil) is found in liquid form and contains a larger amount of the elemental carbon, while the non-volatile rock species also called carbon (not to be confused with the elemental carbon) contains a very large amount of the elemental carbon. Anthracite consists almost of pure carbon. All of these fuels are very important for trade. There are also other fossil fuels that are largely untapped, such as oil shale, various sedimentary rocks containing hydrocarbons.

Answer:

Because Intercalary meristems are found in the the stem part of the sugarcane in whole length.

Explanation:

As we have studied about meristem regions, that these are the regions found at the nodal areas which are able of cell division and growth. Intercalary meristem are present in the nodes of sugarcane stem which lead to the rapid increase in elongation of stem.
Intercalary meristem are located at the base of leaves and nodes that leads to the increase in length.
On the tip of sugarcane, apical or tip region meristem are found. When the tip region is removed, the presence of intercalary meristems play the role by facilitating the elongation of stems in sugarcane.

He portion of the membrane that faces the lumen is called the ________ membrane.

irina1246 [14]

The portion of the membrane that faces the lumen is called the apical membrane.

Membrane is the lipid bilayer that surrounds the cell on its outer surface. The membrane serves various functions like: protection, cell shape and integrity and regulate the traffic of molecules across the membrane. It is semi-permeable in nature.

Lumen is the hollow portion present inside any organ or tube like the artery or intestine. It is a Latin word that means 'an opening'. The lumen of different organs served various purposes. However, the major function is the transport of substances like air, nutrients, waste materials, immune cells, hormones, etc.
