Answer:
C. 30 min minutes a day 5 days a week of moderate-intensity exercise or 20 minutes a day 3 days a week of vigorously intense exercise
Explanation:
The combination of aerobic and muscle-strengthening physical activity is crucial for a healthy lifestyle. Regular physical activity can help to reduce the risk of cardiovascular and chronic diseases, disability and premature mortality.
Adults need a moderate physical aerobic activity for a minimum of 30 minutes 5 days a week or 20 minutes of vigorous-intensity aerobic activity. A combination of these two can be done to achieve this goal.
A moderate-intensity physical activity, like <u>fast walking</u>, should produce a noticeable rise in heart rate and breathing. On the other hand, a vigorous-intensity activity, like <u>running</u>, should produce a large and bigger change in heart rate and breathing.
The muscle-strengthening activity, should be performed for a minimum of 2 days a week on two or more nonconsecutive days.
Given what we know, we can confirm that as scientists study fossil records, they can learn much about the species, such as the traits and activities of the organisms in question.
<h3>What does each fossil type teach us?</h3>
- Trace fossils such as footprints can teach us about the activities of the organisms.
- Meanwhile, scientists will use body fossils to learn about the specific traits of early organisms.
- Body fossils can at times also provide insight as to the diet of the species.
Therefore, we can confirm that scientists will use body fossils to learn more about the traits and diets of early organisms while using the uncovered trace fossils to track the activities of these organisms.

Answer:
Without wind systems warm, moist air won't move around. Water might still evaporate but it won't travel meaning anywhere away from a large body of water will dry up. ... Plants, animals and humans will slowly die from dehydration with most water inaccessible as salt water or ice.
Explanation:
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.
