Answer:
The formation of foam is a process when the small bubbles of the gas get trapped inside a solid or a liquid a form is made and gets made by the tapping of millions of small bubbles and can be seen in marshmallows. The process of foam formation is thus through a dispersed medium and in general gas is present.
The foam is thus evidence that respiration, is taking place as carbon dioxide is a product of respiration.
Explanation:
Answer:
the advances would be very good for the rate
Explanation:
Methods for reducing solid waste by reusing discarded materials. Recycling technologies use waste materials to make new products. They involve collecting recyclable materials, manufacturing or reprocessing them into new products, and purchasing products made from recycled materials
Answer:
Both facilitated diffusion and active transport are selective processes. Only selective molecules are allowed to cross the membrane. They utilize carrier proteins to move across the membrane.
Explanation:
Diffusion is the process by which molecules move across a membrane respective of the concentration gradient. The plasma membrane is a <em>selectively permeable membrane</em> which allows specific molecules to move across the concentration gradient.
Molecules migrate from a region of higher concentration to a lower concentration in case of diffusion. It can be classified into simple diffusion and facilitated diffusion. These are examples of <em>passive transport</em>.
In facilitated diffusion molecules move across the concentration gradient with the help of <em>carrier proteins or channel proteins</em>. The carrier proteins bind to the molecule which has to be transported and change conformation to allow it to cross the membrane. For example glucose molecule is carried across through <em>GLUT transporter</em>. <em>Channel proteins</em> open a channel inside the membrane and molecules get transported across the gradient.
Active transport carries molecules against the concentration gradient with the assist of energy. ATP hydrolysis is utilized to generate energy. As a result of active transport, the molecules are aggregated on one side of the membrane.
The answer is B, because salt water has lots salt, and little water. The cells lose their water content and fill up with salt, causing ti to collapse.
