Answer:
A. We can deduce that microorganisms such as Citrobacter have a classification from which it is possible to establish the most favorable environment for it, since being gram-negative, lactose positive, optional anaerobic, not endospore, it will prefer the environment as humid sites and that contain wastewater and soil as well as the intestine, it can therefore remain in some contaminated food and be transmitted with consumption
B. Given the aforementioned characteristics of Citrobacter, it does not infect all people and prefers those who have deficits in its defense mechanisms, thus it becomes a favorable site for colonization of newborns, who do not have adequate immunity, according to the case. Clinically, the neonate was able to acquire the infection in various ways, although the medical personnel who have manipulated it do not have positive tests, the microorganism can adhere to contaminated surfaces and it will be necessary to take samples of the mother's and neonate's feces, as well as the soil. and the water where the infected was, to subsequently carry out disinfection processes in the areas and avoid new infections.
Answer;
Advantages of sexual reproduction:
- It provides genetic variation.
Disadvantages of sexual reproduction:
- Not all mutations are passed on.
- It is time and energy consuming.
- The reproduction process is slow.
Sexual reproduction is a type of reproduction in which genetic information from two genders or sexes combine to produce a offspring. Both the gender produce gametes which fuse to form zygote which develops into an offspring.
There are several advantages and disadvantages associated with sexual reproduction as compared to the asexual reproduction.
The advantages are:
- It provides genetic diversity to the species.
- It naturally increases the levels of diseases resistance throughout the species.
- It can lead to the incorporation of evolutionary advancements in a population.
- It can give a rewarding experience specially in human beings as it releases dopamine in the brain.
- It also helps in improving health, growth of brain cells, relieving pain, can act as anti-depressant etc.
The disadvantages are:
- It is time and energy consuming process.
- Reproduction is uncertain as it is not a 100% successful method for producing offspring.
- Not all favorable variations or mutations are passed on to the next generation.
- Number of offspring produced is usually low.
Answer:
Blood Temperature is regulated by negative feedback in the human body.
Answer:
B. the steam produced has a greater likelihood of being contaminated with radiation than in a pressurized water reactor
Explanation:
A boiling water reactor produces heat using nuclear fission in the reactor core. This causes the water to boil and emit steam. The radiation from the nuclear fission is transferred to the water as it heats up, and the radiation is then emitted with the steam
