O positive is the most common blood type and most likely to be transfused.
O negative donors are the “Universal Donor.” People with O negative blood are universal red blood cell donors. This means that their red blood cells can be transfused to any blood type.
You can use refraction which is the bending of light through a transparent material. Also the freezing and boiling points of water. One last one is the Cartesian five experiment, this shows the density of water. Hope this helped.
Answer:
Softer? I hope this helps :)
Explanation:
<h2>Answer:</h2>
Because condensation on the slant effects the bacterial growth in the test tube.
<h3>Explanation:</h3>
- When agar is solidify in the test tube tilted, it takes a shape of slide on one side of the tube which is known as slat.
- Slant is used instead of petri dishes because they provide more surface area for growth.
- Water in the slat can invade the test tube, making agar unstable and the bacterial growth on the slat will be affected by moisture in bottom of slant.
- In petri dishes, it is no big problem of moisture condensation.
