Answer:

Pasteur observed that the broth in the straight-neck flask was discolored and cloudy, while the broth in the curved-neck flask had not changed.

Explanation:

He concluded that germs in the air were able to fall unobstructed down the straight-necked flask and contaminate the broth. The other flask, however, trapped germs in its curved neck,­ preventing them from reaching the broth, which never changed color or became cloudy.

Hope this helps.

Why is incomplete dominance considered an exception to Mendel's principles of inheritance?
topjm [15]

Incomplete dominance is considered to be an exception of Mendelian inheritance as neither of the alleles is completely dominant over another. The heterozygotes show the blending of traits and show a mix of both the phenotypes.

Juan has been diagnosed with mono, and the doctor wants to determine if his spleen is enlarged. Where (quadrant, etc.) will the
hichkok12 [17]

Answer and Explanation:

  • Where (quadrant, etc.) will the doctor palpate Juan's abdomen?

<em>Under normal conditions in general the spleen can not be palped because of its reduced size. But when it is enlarged it might be easily touched. The spleen is located under the thoracic cage (rib cage) on the left side, between the 8th and 11th ribs. This would correspond to the left superior quadrant (left hemi-belly).</em>

  • What other organs might be compressed by Juan's enlarged spleen?

<em>The enlargement of the spleen and the liver inflammation are symptoms of the mono disease. This enlargement might affect some neighboring organs such as the stomach, which might be displaced and compressed. </em>

  • why is Juan's spleen enlarged and not his stomach or kidney?

<em>The spleen is part of the immunological system and helps the body to fight infections and filter old bloody cells taking them out of the blood current. This organ might get enlarged because blood cells accumulate in its interior. Red blood cells are excessively stored in the spleen, resulting in anemia. The more cells the spleen retains, the larger it becomes, and hence, the more blood cells it retains and destroys. If the spleen is unproperly working, it kills too many red blood cells and accumulates many others.</em>

The Stomach and kidney are not part of the immunity system and they do not filter blood cells, so they do not seem to be affected by their accumulation.

How do obligate aerobes and obligate anaerobes differ in their interactions with the atmosphere?
Crank
<h2>Answer:</h2>

An obligate aerobe, by contrast, cannot make ATP in the absence of oxygen, and obligate anaerobes die in the presence of oxygen.

An obligate aerobe is an organism that requires oxygen to grow. Through cellular respiration, these organisms use oxygen to metabolise substances, like sugars or fats, to obtain energy. In this type of respiration, oxygen serves as the terminal electron acceptor for the electron transport chain.

An Obligate anaerobes are poisoned by oxygen, so they gather at the bottom of the tube where the oxygen concentration is lowest.
