Tom [10]

Sickle cell disorder is an inherited blood disease featured by defective hemoglobin. The condition affects the hemoglobin, or the red blood cells, and their tendency to conduct oxygen. The normal hemoglobin cells are round, smooth, and flexible, and thus, they can travel via the vessels in the body effortlessly.  

On the other hand, the sickle cell hemoglobin cells are sticky and stiff and form a sickle, C shape, when they lose their oxygen. These cells combine together, and cannot effortlessly move through the blood vessels.

An easy way to calculate the amount of energy available at each level is to
Contact [7]

Answer:

Use the rule that 10% of the energy is transferred between layers.

Explanation:

Energy is transferred between layers of a food pyramid. That means that the  producers at the bottom of the pyramid (e.g. green plants) provide energy to the primary consumers (e.g. rabbits), which are eaten by and provide energy to the secondary consumers (e.g. foxes).

However, very little of the energy is actually transferred to the next layer, roughly 10%. So an easy way to calculate the energy available at each level is to calculate 10% of what was available from the previous level. So if there is 600 kJ available from the primary consumers, then 60 kJ are transferred to the secondary consumers

Petri dishes should? always be labeled on the lid. be left open while incoulating. be stored with the lid on top. always be stor
Anna [14]

Petri dishes should always be stored inverted.

In biology, petri dishes are frequently used to produce microorganisms like bacteria, yeast, and mold. The organisms that grow on solid or semisolid surfaces are best suited for it. To reduce the chance of contamination from airborne spore particles landing on them and to avoid the buildup of water condensation that could disrupt or impair a culture, they are often covered and stored inverted.

Aside from that, incubating the media in the normal position could result in the media drying out, which would interfere with the ideal conditions for microbial growth and increase microbial count mistakes. Since the labels are put underneath the plates rather than on the lids, placing plates upside down also makes them easier to handle and recognize.
