Can plants be used as building materials? Could you give me some examples from past and current ones?

Yes, plants can be used for building materials.

Wood of many strong trees was used to build temperorary houses. Wooden toys were also famous earlier.

Today, Timber wood is used for making ships. Wood is also used for making furniture.

Not the plants but the soul could be made into mud in both past and present. In past, most houses(not in the US) but in many countries were made up of soil. But know in present, soil or even mud is used to put it in the concrete to make the building strong in many countries like India. Good luck:)

Bioflix activity: membrane transport -- vocabulary review can you match the processes involved in membrane transport to their de

Natalka [10]

Explanation:

From the diagram with corresponding labels:

Exocytosis
Facilitated diffusion
Endocytosis
Diffusion
Active transport

Further explanation:

Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

Via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid by layer this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Active transport is a mediated process that requires the use of specialized membrane proteins these proteins require energy in the form of avenues and triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules.

Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane. Channel proteins which are pores filled with water versus enabling charged molecules to diffuse across the membrane, from regions of high concentration to regions of lower concentration. This is a passive part of facilitated diffusion

...some very large molecules require specialized type of active transport in order to move across the membrane this includes endocytosis and exocytosis

During endocytosis large molecules cells and cell fragments moved across the plasma membrane through a process of invagination; piece of the external cell membrane falls into itself and forms a small pocket that surrounds the target molecule this breaks off from the membrane to form an intracellular vesicle; different methods of endocytosis such as Phagocytosis, Pinocytosis and receptor-mediated endocytosis, take in cells, water and targeted substances respectively.

Similarly, in exocytosis, the particles (Protein, Waste material etc.) surrounded by a phospholipid membrane. However, this membrane is formed in the cytoplasm, and attaches to the plasma membrane’s interior in a process opposite to endocytosis; material is removed from the cell and exported into the cell’s exterior called the extracellular space.

Is the sun is the ultimate source for energy on the Earth?

lana66690 [7]

Answer: The given statement is true.

Sun is the ultimate source for energy on the Earth. It is the natural and renewable source of energy on earth as it can easily be renewed and never run off. All living organisms which are present on earth are dependent on food for survival. For this, they become part of the food chain which provides them energy in the form of food. Food chain begins with plants as they are the primary producers in the food chain. They get energy for preparing food from sunlight in the form of light energy.

Moreover, the life forms which existed millions of years ago were dependent on sun for energy. The dead remains of these life forms have provided the non renewable sources of energy like fossil fuels on earth.

Thus, the sun is considered as the ultimate source of energy on the Earth.
