Answer:
A. the digestive, muscular, and respiratory
Explanation:
Muscle weakness affects the muscular system (muscles are in the muscular system) , stomach pain affects the digestive system (stomach is a part of the digestive system), and coughing affects the respiratory system (coughing hinders the ability to breathe properly).
Larches trees are usually grown as an ornamental plants, that is, they are grown for their beauty. They are deciduous conifers and evergreen plants. Larches typically need cold climate and plenty of water to grow and they are found in large quantity in Northern Europe, Asia and America.
Larches trees in Siberia are not harvested much because they are majorly planted as ornamental plants.
Answer:
Oil
Explanation:
Oil is the most common fossil fuel internationally, seeing as it is in the top spot for usefulness.
.
Explanation:
1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.
2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.
3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .
4) during fission a copy of the DNA is made and attached to the cell membrane as well. As this cell elongate in preparation for fission, the two DNA copies are pulled apart two opposite ends of the cell. New membrane material is deposited between the two ends of the cell, and a new wall grows between them .
5) UMASS STEM-ED From Bubbles to Cell Membranes Workshop. Bubble ... dynamic nature which can't be properly appreciated in a static textbook. ... the small thread through one of the straws.
6) example of passive transport and active transport across a cell membrane so, cell membranes are semipermeable meaning they have control over what molecules can or cannot pass through. Some molecules can just drift Inn.
