Answer:
Take in carbon dioxide, reduces water loss, and produce oxygen.
Explanation: Hi! I've learned about these things in the past, really tough stuff! Hopefully this helps, I believe the three options above are correct, only one I'm possibly questioning is producing oxygen. Good luck!
False I believe. Hope this helps :)
Answer:
Half-Life = 18 days
Explanation:
Isotope decay follows the equation:
Ln[A] = -kt + ln[A]₀
<em>Where [A] is amount of isotope after time t,</em>
<em>k is rate constant</em>
<em>[A]₀ is initial amount of isotope.</em>
<em> </em>
If we solve rate constant, we can find half-life by using:
Half-life = ln 2 / Rate constant
Replacing in isotope decay equation:
Ln[1/8] = -k*54 days + ln[1]
-2.07944 = -54k
0.0385days⁻¹ = k
Half-Life = ln 2 / 0.0385days⁻¹
<h3>Half-Life = 18 days</h3>

Answer:
A positively charged nucleus consisting of protons and neutrons
Explanation:
The atomic nucleus is a positively charged region located at the core of an atom that consists of positively charged protons and neutral neutrons while the negatively charged electrons make up the outer cloud (electrons are therefore not contained in the nucleus).
