Answer:
diffusion through a selectively permeable membrane
Explanation:
The cell membrane selectively allows certain substances to enter or leave a cell . This implies that cell membranes are selectively permeable; they allow some substances to pass through, but not others.
Direct transport of materials across the cell membrane is often passive. Passive transport does not require energy to occur. Passive transport is the movement of substances from a region of higher concentration to a region of lower concentration. A concentration gradient is always required.
The diffusion through a selectively permeable membrane is an example of passive transport.
The iodine moves into the dialysis tube across the semi permeable cell membrane from a region of higher concentration to a region of lower concentration in response to a concentration gradient.
Answer:
<em>slat</em><em>e</em><em>,</em><em> phyllite</em><em>,</em><em>schist</em><em> </em><em>and</em><em> </em><em>gnei</em><em>ss</em>
The right answer for the question that is being asked and shown above is that: "a.Cyanobacteria are photoautotrophs." The atmosphere that we depend on for our survival is enriched by numerous cyanobacteria. This fact justifies the characteristic of cyanobacteria that is Cyanobacteria are photoautotrophs.
Answer:
E. Clostridium AND Lactobacilli
Explanation:
The microorganisms which form a colony in the human vagina is called vaginal flora or vaginal microbiota. The genus <em>Lactobacilli</em> which are Gram-positive, rod-shaped bacteria and the genus <em>Clostridium</em><em> </em>also a Gram-positive bacteria make a colony in the vagina of the human female reproductive tract. The Lactobacilli bacteria produces lactic acid which protects women against the infection by pathogens. Thus, these bacteria impact on the overall health of women.
The dirt and fragments decompose and give the plant proteins/nutrients. Soil also anchors roots down and provides some water
