Answer:
Colony collapse disorder (CCD)
Explanation:
Colony collapse disorder (CCD) -
It refers to peculiar condition , where the worker bees vanished leaving the food as well as the queen bee with some immature bees and nurse bees .
This situation was named the colony collapse disorder .
The condition was observed in north America along with Europe in the late 2006 .
The phenomena became global with affecting the areas of Africa and Asian countries .
Hence , from the given question ,
The correct answer is Colony collapse disorder (CCD) .
Answer:
The best answer to the question: Recovery from a severe metabolic acidosis is most dependent on which of the following? would be, D: Arterial pH.
Explanation:
When a person reaches such a severe situation, as having metabolic acidosis, then it means that his body systems are not being able to use the mechanisms to restore the normal acid-base balance within it. Normally, a person needs to have an acid-base balance of 7.35 to 7.45. Drops below or above these numbers will result in acidosis or alkalosis and in severe problems. The way that the body can tell if there is something going on with the pH levels in the blood is through a series of chemoreceptors, especially in the neck, that constantly measures the amount of CO2 molecules in the blood and especially, the pH (acidity or alkalinity) given by the excessive presence, or absence, of acids in the blood. There is another ration that is important for the body, and it is the presence of bicarbonate ions, which will help balance out the amount of H+ ions produced by normal cell function, or increased cell function. In metabolic acidosis, the amount of H+ vs. bicarbonate ions is immense, H+ winning by far over bicarnonate, and a series of steps are taken by the body to restore the 20:1 ratio, and especially return the pH to its normal range. All mechanisms point towards that one measure: pH. Once the level of pH has been reached, we can tell a person is finally coming out of metabolic, or recovering from, metabolic acidosis.
Answer: B, health and safety. Hopefully that helps!
Answer: Measures the antigen levels on the cell surface
Explanation: Fluorescence-Activated Cell Sorting. Fluorescence-activated cell sorting (FACS) measures the antigen levels on the cell surface quantitatively. Cells are dyed with a fluorescent antibody, then placed in a stream of liquid which passes the focus of a laser, and each cell emits light.
