Answer:
<em>Cellular transport is the movement of ions or molecules across the membrane of the cell through either active or passive process.</em>
Explanation:
During active transport, ATP (Adenosine triphosphate) is used. In passive transport, ATP is not used. In active cellular transport, the ions move across the membrane against the concentration gradient.
For ATP to be used, it has to get hydrolyzed thereby forming ADP and inorganic phosphate. On the other hand, ADP captures the energy through the oxidation process taking place in the cell.
Freshwater marshes occur beside rivers and oceans.
Yes, this statement is true .
Freshwater marshes conatins fresh water . They are generally found near the river mouths. They are found along the fringes of lakes and rivers where the water table, the upper surface of underground water, is very high. Marshes are useful for the damage cause by the flood storing the water.
Answer:Lipids perform three primary biological functions within the body: they serve as structural components of cell membranes, function as energy storehouses, and function as important signaling molecules. The three main types of lipids are triacylglycerols (also called triglycerides), phospholipids, and sterols.
triglycerides- fat
phospholipids- plant and animal cell membrane
sterols- plant and animal cell membrane's microorganism.
Explanation:
That should be sensitivity. it's what we react to the environment. we can detect what is happening in the environment.
there are 7 different characteristic of living things, and sensitivity is one of them
Answer: <em>The steps used in scientific methods are to ask a question, form a hypothesis, test the hypothesis, analyze the results, draw conclusions, and communicate results. A controlled experiment tests only one factor at a time so that scientists can determine the effects of changes to just that one factor.</em>
