The child is more susceptible to diseases than the father because the father has already gained a slight immunity towards the lead by loving in the house longer than the child (assuming the father has lived in the house longer)
The EMB (Eosin Methylene Blue) agar is a selective and differential agar medium. It contains sucrose and lactose as fermentable substrates together with Eosin Y and methylene blue dyes which in combination gives the agar its characteristic color when prepared and serves as a pH indicator as well as an inhibitor of growth of Gram-positive bacteria. Hence, it is primarily used to isolate Gram-negative fecal coliforms while some positive fecal coliforms such as Staphylococci are also able to grow.
These coliforms are of two types:
- Lactose or sucrose fermenting coliforms form metallic sheens on the agar as a result of acid production and the response of the indicator to the increased acidity.
- Non-lactose/sucrose fermenters are only able to produce acid by protein deamination. Hence they either form colorless or pinkish colonies on the agar
On the other hand, Mannitol salt agar is a selective and differential agar medium that is primarily used to isolate Staphylococcal bacteria. The presence of sodium chloride in the medium makes it a partial or complete inhibitor of other bacteria.
Hence, an unknown bacterium that forms colorless colonies on EMB will either be a non-lactose fermenting, Gram-negative coliform that will hardly grow on Mannitol salt agar, or a Gram-positive fecal Staphylococcus.
Staphylococci bacteria are of two types:
- Coagulase-positive will form yellow colonies on the Mannitol salt agar.
- Coagulase-negative will form red colonies on the Mannitol salt agar.

The answer is identical to the original body cell or it is half of the original body cell.
A cell cannot live forever so they either divide into two new cells through mitosis or die.In the process of mitosis <span>one cell divides into two identical cells. So, a genetic material in the nucleus of each of the new cells will be identical to the original body cell.
</span>Beside mitosis, there is meiosis. It i<span>s a cell division that results in the reduction of chromosome number by half. In this case, new cells will be haploid and there will be half less genetic material than it the original body cell.</span>
Vacuoles are vesicles<span> that contain mostly water and are found in plant cells. They transport water in and out of the cell. ... Transport </span>vesicles<span> work primarily with the endoplasmic reticulum and the Golgi apparatus. They transport molecules such as proteins and fats in between these two organelles.</span>
