In the question, it is not mentioned that which fish is dominant and recessive, so lets consider red fish is dominant and yellow fish is recessive.
Answer:
In complete dominance, the dominant trait completely masks the recessive trait and the offspring shows dominant characters only.
When a red and yellow fish were crossed, the pattern of inheritance is complete dominance which means the offspring would have dominant characters.
As we considered, red fish has dominant trait so the offspring produced will also have red color as yellow color (recessive) will be masked by dominant red color fish.
Answer:
A. Shigella are H2S + and motile, Salmonella are H2S - and nonmotile
Explanation:
<em>Shigella</em> is a genus of Gram-negative (i.e., they have a cell wall composed of a thin layer of peptidoglycan), nonmotile, and facultative anaerobic bacteria; whereas <em>Salmonella</em> species are Gram-negative and facultative anaerobic bacteria. Moreover, <em>Salmonella</em> are motile bacteria, in a similar way to other human pathogenic bacteria (e.g., <em>Vibrio cholerae, Pseudomonas aeruginosa</em>, and <em>E. coli</em>). Salmonella can produce hydrogen sulfide (H2S) from thiosulfate or sulfite; whereas <em>Shigella</em> species are unable to produce hydrogen sulfide. Typhoid fever, also known as enteric fever, is an infection caused by <em>S. typhi</em> that can spread throughout the body and affect different organs (i.e., it is a multisystemic illness). Vivotif (Typhoid Vaccine Live Oral Ty21a) is a live attenuated bacterial vaccine used for oral administration only; whereas Vi capsular polysaccharide vaccine (ViCPS) is a vaccine administered by injection. Finally, shigellosis is an infection that affects the digestive system caused by <em>Shigella</em> bacteria. In this regard, <em>S. dysenteriae </em>produces a potent cytotoxin known as 'Shiga toxin' that may cause local destruction of the colonic epithelium.
<span>The nurse should let the patient know that with every pregnancy, there is actually 50 percent chance of a carrier passing on under this condition or being a carrier.
But not all pregnancies may result to this. The sex of the child will have a great impact on the outcome and it cannot be as a result of the previous pregnancy.
Haemophilia is being termed as an inherited genetic disorder. It results from much to people who bleed longer after an injury. There are two types of hemophilia.
For example, hemophilia A which occurs if there is no enough clot factor VIII. The other one is hemophilia B which occurs if there is no enough clot factor IX.</span>
Answer:
7
Explanation:
There are 12 total pairs of ribs. 1-7 are attached directly to the sternum by costal cartilages, making them true pairs. 8-10 are fake pairs, which means they're attached indirectly to the sternum. And 11 and 12 and free floating ribs, meaning they aren't attached.
