Red blood cells will swell and burst.
The reason behind this is that red blood cells are okay when they are in the plasma (the watery part of the blood) because the solutes in plasma are so well balanced that plasma is rendered isotonic. An isotonic solution is a type of solution that has the same salt concentration as its surrounding environment and thus the substances around it e.g. cells neither gain nor lose water. In the blood plasma, the red blood cells neither lose nor gain water and so they remain intact.
However distilled water is hypotonic (has less or no solutes) and therefore osmosis will take place when red blood cell which have a higher solute concentration are placed in it. Water molecules will leave the distilled water and pass into the red blood cells through the semi-permeable membrane of the cells in an attempt to equalize the difference in osmotic pressure on either side of the membrane. In so doing, water will accumulate in the cell which will then swell to capacity and ultimately burst.
Answer: C
Explanation:
HIV is classified as a retrovirus because its genetic material is composed of single-stranded RNA nucleotide. And also Retroviruses have the enzyme reverse transcriptase, which is capable of making a DNA copy of its RNA once inside the infected host cell
Answer: pubic symphysis
Explanation:
The amphiarthrosis is the joint which shows limited mobility. This joint is a kind of cartilaginous joint which unites the body of two vertebral bones.
The amphiarthrosis articulation can be seen at the pubic symphysis of the pelvis. This cartilaginous joint strongly anchors the pubic region of the right and left hip bones. This region exhibit restricted mobility. The strength of this region helps in the weight-bearing stability of the pelvis during pregnancy.
The main thing to understand about Parkinson’s Disease is that it is a disease of the brain that creates coordination difficulties in those who suffer from it.
There are a total of 5 stages of Parkinson’s, so stage 3 is considered the turning point for the disease. Many of the clinical manifestations will match with those seen in stage 2 (walking issues, tremors and stiffness on both sides of the body). In stage 3, balancing issues will show up, causing an increased fall risk. Dressing may become more difficult to do alone due to stiffness in the body. Movements and reflexes with also slow with the growing stiffness.
