An autotroph is an organism that can feed itself, like how plants feed themselves with photosynthesis. Autotrophs include flowers and other plants. It also includes other species that do this process. A heteroph is a organism that eats others for food. They can eat fungi and bacteria. They also can eat the things they are growing on.
Hope this helps you out!
Tapping of geothermal energy
to produce electricity is done on a larger scale compared to the tapping of
the geothermal gradient using a geothermal heat pump. Harnessing geothermal energy is also reliant on geological conditions such as in the area
of convection boundaries while geothermal
gradient can be harnessed virtually
anywhere on the earth surface.
True, communication most noticeably so. Transport has too
Answer:
"As a molecule moves through the plasma membrane it passes through <em>a hydrophilic layer of phospholipid heads then a hydrophobic layer of phospholipid tails and then another hydrophilic layer of phospholipid heads".</em>
Explanation:
Biological membranes are formed by two lipidic layers, proteins, and glucans.
Lipids characterize for being amphipathic molecules, which means that they have both a hydrophilic portion and a hydrophobic portion at the same time. These molecules have a lipidic head that corresponds to a negatively charged phosphate group, which is the polar and hydrophilic portion. They also have two lipidic tails that correspond to the hydrocarbon chains -the apolar and hydrophobic portion- of the fatty acids that esterify glycerol.
Membrane lipids are arranged with their hydrophilic polar heads facing the exterior and the interior of the cells, while their hydrophobic tails are against each other, constituting the internal part of the membrane.
Through this lipidic bilayer, some molecules can move from one side of the cell to the other, which happens because of concentration differences. When this occurs, molecules must pass through the hydrophilic layer of phospholipid heads then through the hydrophobic layer of phospholipid tails and then again through another hydrophilic layer of phospholipid heads.
ANSWER IS : A troposphere
