Answer:
Regarding pathogens, the statement that is true is that viruses cannot reproduce on their own.
Explanation:
Viruses are pathogenic agents not considered as living beings, since they are only constituted by genetic material surrounded by a viral capsid, besides not fulfilling vital functions.
These agents are unable to reproduce on their own, so they need to place their genetic material —DNA or RNA— inside a host cell, to modify its nuclear DNA and be able to reproduce.
The other options are not correct because:
- <u><em>Influenza can cause an upset stomach</em></u><em>. Influenza primarily affects the respiratory system.</em>
- <u><em>Pathogens affect everyone equally.</em></u><em> Each individual's immune response is different when exposed to the same pathogen.
</em>
- <u><em>Fungi are large, stoneflies organisms</em></u><em>. The pathogenic fungi, such as Candida albicans and Trichophyton, are different from the mushrooms and fungi that can be seen in soil or decomposed organic matter.</em>

The second trimester is when the respiratory system is mature.
Cardiovascular fitness is best described as B. the ability of the body
to transport oxygenated blood efficiently. Cardiovascular fitness is
improved by regular aerobic exercises and help to strengthen the cardiac
muscles, making the heart more efficient in pumping blood through the
body. Moreover, cardiac efficiency decreases the resting heart rate of a
person as their heart is more effective in transporting blood with each
contraction.

The correct answer is A. stretch, warm-up, workout, stretch.
When you decide to start working out, the first thing you need to do is stretch your body - without it, your work out won't be successful. After that, you need to warm up your body so as to avoid any injury. After you finish working out, it is important to stretch again, to complete your session.
