The model demonstrating the importance of solar energy for life on Earth in which the student should make is a model of a local food web
All food chains begin by receiving the energy of the sun. This energy is captured by plants which are the producer link in the chain. Plants are able to utilize the light energy from the sun to produce food such as sugar from carbon dioxide and water.
The device detects electrical activity in the motor cortex of the brain. The device transmits the electrical signals to a series of computers. The computers translate the signals and produce an output that controls the movements of the prosthesis.
PALISADE CELLS ARE CELLS FOUND WITHIN THE MESOPHYLL IN LEAVES OF DICOTYLED ON PLANTS.THEY CONTAIN CHLLORPLASTS,WHICH CONVERT THE ENERGY STORED IN PHOTONS TO CHEMICAL ENERGY THROUGH PHOTOSYNTHESSIS,WHICH IS MADE UP OF TWO MIN STAGES;THE LIGHT DEPENDENT REACTIONS AND LIGHT INDEPENT REACTIONS
Answer:
B
Explanation:
The fatty acid tails of phospholipids are hydrophobic – meaning they are ‘water-hating’. This is why they are in the middle of the bi-lipid layer of the cell membrane 'hiding' from the 'watery' environment of a cell. This poses a challenge in the diffusion of large and charged molecules across the membrane -such as sodium ions. Such molecules need transmembrane protein channels to help them cross the membrane. These are called integral proteins because they are part and parcel of the cell membrane. The cell membrane, in addition, also has glycolipids and glycoproteins on its surface that are significant in the identification of the cell by other cells.
