Shtirlitz [24]

Answer:

<u>Option-(True):</u> The methodology used to discover the pattern of evolution among an assemblage of species is based on the assumption of descent with modification.

Explanation:

<u>Evolution and patterns of evolution:</u>

The phenomenon of evolution is very interesting as it can any two different species back to a common origin or ancestors. While the process of evolution does not occur in few years or centuries, as it takes millions of years for any specie to evolve from a less developed form of body or any system to a more complex or advance form.

Now, evolution occurs in many forms or patterns. As it species can originate from a single ancestor or descendant, while the evolution can occur inside the organism may occur in different patterns. These patterns are as follows:

  1. <u>Divergent Evolution:</u>The divergent evolution occurs when the species originated from a single ancestor or descendant results in different forms of organisms. As it brings diversity among the species belonging to same ancestors or origin. For example, the humans and apes.
  2. <u>Convergent Evolution: </u>The convergent evolution takes place inside the number of species when they are originated from the different species but they share the same medium or region to live in and share some of the similar resources between them. For example, The whales are mammals but they too live with the fish species inside the water.
  3. <u>Parallel Evolution:</u>When the evolved organisms or species are related to the different ancestors or descendants, as they share they do not share the same niche(way of life), as the species are unrelated to one another.

A bacterial culture is being tested for its ability to reduce nitrate. After incubation and growth of the bacteria in nitrate br
skelet666 [1.2K]

Answer:

All this combination of reactions is summarized in that the bacteria reduced nitrate, that is, they added protons to said compound, giving nitrite as a product.

By promoting the appearance of nitrite and that it increases in its concentrations when the zinc dust is thrown away, it becomes reddish since there was a change in pH, that is, the medium was acidified.

Explanation:

Some bacteria take nitrate as a source and end up generating an oxide reduction reaction that gives nitrite as a product, if this reaction advances in a chain, that is, the nitrite is reduced after the nitrate, the product in the future would be ammonia

A laboring client who is positive for group B Streptococcus (GBS) is given an initial dose of 2 g of ampicillin at 9 AM. Accordi
Vikki [24]

Answer:

The next dose will be 1 g of ampicillin after 4 hours.

Intrapartum antibiotic administration to women with group B that tested ampicillin or penicillin G, either antibiotic should first be considered for(2 g of ampicillin IV followed by 1 g every four hours until giving birth.

Explanation:

Group B streptococci (GBS) colonizes the vagina and rectum in 10–30% of pregnant women.1 In the newborn, GBS is a leading cause of neonatal sepsis and a major cause of pneumonia and meningitis.2

In 2002, the Centers for Disease Control and Prevention (CDC) issued guidelines to recommend that all pregnant women be screened at 35–37 weeks of gestation for GBS and, if positive, treated with intrapartum antibiotic prophylaxis. The aims of prophylaxis are 1) to decrease colony counts at the time of delivery; 2) to prevent the organism from ascending and proliferating in the amniotic fluid compartment; and 3) to achieve adequate levels of effective antibiotic in the fetal bloodstream during labor.

For Ampicillin  nonallergic patients, the protocol recommends a 2 g unit infusion of ampicillin, followed by 1 g  every 4 hours until delivery.3 At least 4 hours of intrapartum antibiotic prophylaxis are recommended.
