Answer:

The correct answer will be- the amount of ammonia will decrease in lithosphere and the amount of nitrogen in atmosphere will increase.

Explanation:

Nitrogen is the most abundant element present in the atmosphere as it constitutes 78% of the atmospheric gases.

The major cause of nitrogen fixation on Earth is biological nitrogen fixation which takes place due to the ability of prokaryotes to utilize atmospheric nitrogen as they possess an enzyme called nitrogenase. The nitrogenase converts the atmospheric nitrogen to a usable form that is ammonia (NH₃).  

In the given condition, if virus inactivates the nitrogenase enzyme, then atmospheric nitrogen will not be converted to ammonia as a result of which the Amount of ammonia of soil decreases in the soil and the atmospheric nitrogen will increase.

The correct answer is B. Sensitive period

Explanation:

In development, the sensitive period refers to a lapse of time in which organisms are more susceptible or receptive to stimuli and therefore during this time there can be great advances in development. Additionally, different from critical periods sensitive periods do not imply irreversible consequence if the stimuli are not presented. For example, in human beings from birth to the age of 6 years, children are more receptive to learn and acquire certain skills such as learning a new language if exposed to it and therefore this can be considered as a sensitive period. Considering this, it can be concluded the definition presented refers to the Sensitive period.

Answer:

A scientist's response to the increase in food poisoning sick patients should be examining the type and source within the foods consumed.

Explanation:

Food poisoning involves the effects that decomposed or contaminated food can have on a group of people who eat it, and can cause illness in all or most individuals.

Although patients' symptoms should be treated and preventive education provided, the best course of action for a scientist is to investigate the cause.

The response of a scientist to the increase in food poisoning cases is to determine the type and source of food, as well as the nature of the alteration it has -decomposition, contamination, bacteria- in order to <u>eliminate the source and avoid new cases</u>.

  • <em>The other options may be valid in the face of the appearance of food poisoning cases, but they are not the best procedure with which a scientist would respond. </em>
