Macrophages rid the body of worn-out cells and other debris.
I believe this is done to ensure accuracy. DNA paternity testing involves the use of DNA profiling to determine whether two individuals are biologically parent and a child. The test establishes genetic proof whether a man is the biological father of the individual in question. There is need for use of more than one loci probes to make sure there is no error and that the results are 100% accurate.
according to sciencethreads.com
it states the following pros and advantages of fossil fuels..
<em><u>1)Fossil fuels have a very high calorific value. </u></em>
<em><u>2)the energy produced by fossil fuels is greater than that produced by an equivalent amount of other energy resource.</u></em>
<em><u>3)Systems are set up to process and utilize oil and gas
</u></em>
<em><u>4)Widely available around the globe
</u></em>
<em><u>5)low cost per unit energy
</u></em>
<em><u>6)Refineries, transportation, and plastics all rely heavily on oil and gas
</u></em>
<em><u>7)High energy output
</u></em>
<em><u>8)Employs millions of people globally
</u></em>
<em><u>9)The primary source of all plastics</u></em>
hope this helps :)
I think the correct answer is b
A)
size = (number of minor spaces x 10μm) / number of ocular spaces
= (2 x 10) / 1
= 20μm
b)Since the RBC has a size of 8μm and the bacterium 20μm, the bacteria is bigger. The Bacterium is bigger than the RBC by 20μm / 8μm
Hence the bacterium is 2.5 times bigger than the RBC.
