Answer:
Contraction is prevented
Explanation:
The sarcomere is the basic contratile unit of muscle i.e the unit responsible for contraction in the muscle and it consist of two main protein actin; which forms filaments involved in contraction and myosin; a motor protein responsible for contraction. Calcium interacts with these protein and in the absence of Ca, contraction is inhibited (sacromere with not be able to undergo contraction)
Answer:
As liposomes with red blood cell membranes burst more rapidly than those made from egg membranes, we consider these liposomes as more hypertonic respect to water, than those derived from frog egg cells.
Explanation:
Osmosis is a process where water can cross a semipermeable membrane in a gradient way. Water tends to move from a high concentration of solvent to a low concentration. Then, water goes in through the liposome to dilute its solute content, as it's not easy for molecules inside to go out of the usually impermeable membrane bilayers.
Answer: True.
Spleen framework is created by reticular fibres from reticular cells.
Explanation:
Spleen is an organ found mostly in vertebrates. It develop from mesenchymal cells within the dorsal of mesogastrium near the greater curvature stomach. The mesencymal cells then divide and differentied to form framework of connective tissues of spleen. The framework of spleen is created by reticular fibres of the reticular cells. Reticular fibres are fibres in the connective tissue that is composed of type iii collagen secreted by reticular cells. Spleen function in filtering of blood. It plays a major role in red blood cells and immune system.
The nurse can give the following instructions:
1. the procedure will most likely last for ten minutes
