Answer:
there might be fewer rabbits and foxes
Explanation:
If carrots were removed from the food web then there might be fewer rabbits and foxes. This is because based on this web, carrots make up 50% of the rabbit's diet. If this is removed, then there would not be enough food to maintain the same size population and the population will begin to shrink. This also applies to the fox population since their main source of food are the rabbits. If the rabbit population decreases, then the fox population will decrease as well since their food supply has shrunk and will not be able to maintain the current fox population size.
This is based on my assumption that brown is dominant over blue.
Since both parent have parents who are homo_zygous recessive, this tells us that both parents will be hetero_zygous.
When you cross two hetero_zygous parents, it can produce these genotypic and phenotypic ratios:
<u>Genotypic</u>
BB : Bb : bb
1 : 2 : 1
<u>Phenotypic</u>
brown : blue
3 : 1
Therefore there is a 75% chance that they will produce a brown-eyed offspring.
Answer:
Gelation is the analytical signal used for the qualitative and quantitative detection of lipopolysaccharides. Bacterial endotoxins are lipopolysaccharides (LPS) located exclusively on the outer membrane of gram-negative bacteria; Their presence in injectable pharmaceutical products may be associated with problems during production, there are established endotoxin limits for this type of product. When the reagent is faced with solutions containing endotoxins, it produces gelling.
Explanation:
The LAL (Limulus Amebocyte Lysate) test is used to detect and quantify endotoxins associated with gram-negative bacteria. It is based on the amebocytes from the blood of the Limulus polifemus crab gel in the presence of minimal concentrations of endotoxin (ng / ml of blood ). It is positive in 60% of bacilli due to gram-negative enteric bacilli. The presence of endotoxins is determined by the formation of an insoluble gel or clot. The reaction requires the presence of divalent cations. The speed of the reaction depends on the endotoxin concentration, the pH and the temperature. The lysate contains a cascade enzyme system that is progressively activated in the presence of endotoxins. As a final result, the coagulable protein (coagulogen) is transformed into a gel (coagulin), which is the basis of the tube gel method.
