Plasma membrane is the structure which covers up the uptaken molecule.
<h3><u>Explanation:</u></h3>
Uptaking of nutrients from the surrounding needs to be very appropriate for the cell to obtain nutrition, as well as to maintain cell immunity. In case of simpler molecules like glucose etc, the molecules are taken inside the cell by means of specific channels or transport proteins. In case of complex molecules, cells prefer to perform endocytosis - either phagocytosis for solid ones, and pinocytosis for liquid ones.
When the cell finds something which can be taken in, it projects a fold of cell membrane towards the liquid which surrounds part of the liquid, or fully. This cell membrane then presents a depression which covers up the liquid. Then the margins of the depression come closer and ultimately fuse, leaving the liquid inside the cell enclosed with a part of cell membrane. This then fuses with a primary lysozome to form a digestive vacoule, a secondary lysozome, a residual body, and ultimately gets excreted off the cell.
Answer: Circulatory and respiratory system
During a process of workout, the rate of breathing increases, because of increase in demand of oxygen by the body. Work out affects the function of the lungs which is a part of the respiratory system. The heart tries to pump out blood fastly, to transfer oxygenated blood all over the body. The heat energy is liberated in this process, which results in the release of sweat by the skin. The sweat gets evaporated by the external air, which keeps the body cool.
Lymphatic capillaries are just a bit larger than blood capillaries. Another way both vessels differ from each other is the mere fact that lymphatic capillaries have closed ends, unlike blood capillaries.
Answer: Spleen
Explanation:
The Spleen is an organ situated above the stomach and carry out important functions for body defence. This functions include:
- destruction of old red blood cells
- elimination of wastes such as dead platelets from the bloodstream
- storage of newly formed platelets.
