Answer:
It allows rapid conduction of water from one vessel element to the next.
Explanation:
Vessels are one of the two types of conducting cells of xylem. Vessels are made of vessel elements. Vessel elements are the individual cells with perforation plates. The perforation plates have large holes (perforations). Perforation plates of adjacent vessel elements allow easier conduction of water from one vessel element to the next.
The perforated end walls of vessel elements allow these conducting cells to conduct water more readily than tracheids. Stacking of vessel elements with perforated end walls make the vessel like a water pipe through which water is being readily conducted.
Answer:
Explanation:
Decontamination is a process of cleaning the materials to an extent to remove the contaminants from them like microorganism, chemicals, dust, dirt and radioactive substances.
The decontamination of the given material can be done for each of the following:
1) Decontamination of pillow - Sterilizer called as UVC sterilizer can be used which uses the UV light to detect and destroy the germs of bubonic plaque that is transmitted by the bite of the flea. After sterilization vaccuming of the pillow can be done to remove the dead germs.
2) Used disposable syringes- It should be placed in a sharp heavy duty plastic container like detergent or bleach bottle. The bottle must be puncture resistant.
<span>Cell division serves as a means of reproduction in unicellular organisms through binary fission. In multicellular organisms, cell division aids in the formation of gametes, which are cells that combine with others to form sexually produced offspring. For growth to occur in living organisms, the number of cells have to increase through cell division until it reaches its maximum size.
The human body also repairs injuries by means of cell division. When skin is cut, the skin cells on either side of the cut divide to make new cells that heal the wound.</span>
Physiological changes during pregnancy aid the adaptation of the cardiovascular system to the grown metabolic needs of the mother which enables adequate delivery of oxygenated blood to peripheral tissues and the fetus. In the postpartum period, the Hemodynamic parameters slowly return to its baseline values, but the full resolution may take in six months after giving birth. The blood volume also decreases by 10% within 3 days after giving birth. The hemoglobin level and the hematocrit will stabilize after 2 weeks. The systolic and diastolic pressure will stay the same from late pregnancy until 12 weeks postpartum. Within 2 weeks of postpartum, the systemic vascular resistance will increase by 30%
