.:Answer:Many bears hibernate in caves during winter
Explanation:
Pure culture can be prepared from a mixture of cultures by using the streak plate method. This enables the bacterial cells to be diluted to obtain a pure culture after many-folds dilution.
Pure culture is the one in which only one species, strain or clone of bacteria are grown. The pure culture enables to scientists to study in detail about its anatomy, lifestyle and potential uses or harms, without the interference of any other microbe.
Streak-plate method is the most commonly used technique in microbiology labs to isolate a single type of bacteria. It is performed by creating the smears of bacteria in zig-zag motion to dilute its concentration.

<span>the temperature at which a phase change takes place depends on pressure. For instance because there is more pressure at low altitudes than at high altitudes, water boils at less than 100 degrees Celsius at high altitudes like mount Everest. In general, the higher the pressure, the higher the melting and boiling points are. Therefore potentially the melting point of iron-nickel alloys is significantly greater in the Earth's core than on the Earth's surface due to an enormous pressure within the Eaerth's core.</span>
Answer:
a cell membrane is made up of 3 main ingredients, that are-
phospholipids, cholesterol and proteins. cell membrane is consists of lipid bilayer, cholesterols and integral and peripheral proteins. among them, lipid is largest portion that cell membrane has.
so, if a drug needs to be uptaken by the cell in a better manner then it has to couple with lipids.<em> </em>By coupling up with the lipids is the easiest and better way to be uptaken by the desired cell.
Answer:
<h3>
<em><u>B cells</u></em></h3>
Explanation:
B cells are the major cell type involved in the humoral immune response. When a foreign antigen (one coming from a pathogen, for example) is detected, B cells in the body that recognize that antigen will begin to produce antibodies as a means of fighting off the foreign invader.
Hope this help!
Have a wonderful day!!!
