Answer:
The protection of internal environment from the harms of fluctuations in external environment is termed as homeostasis.
Explanation:
Homeostasis is the central requirement in the maintenance of an organism, which compels the adaptations in the constant changing condition and contribute in evolutionary process.
Answer:
7.680 mol Pt Se aptse.
Convert 0.400 moles of BF3 to molecules.
0.400 mal BF3 x 6.02x 18 molecules BF3 = 2.4px 10.
Answer: The percent ionization is higher for 0.010 M solution of 
Explanation:
cM 0M 0M
So dissociation constant will be:
a) Given c= 0.10 M and 
= ?
Putting in the values we get:
b) Given c= 0.010 M and = ?
Putting in the values we get:
The percent ionization is higher for 0.010 M solution of
The volume (in mL) of methylergonovine the nurse should draw up in the syringeis is 0.25 mL
<h3>What is density? </h3>
The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as
Density = mass / volume
With the concept of density, we can obtain the volume of methylergonovine. Details below
<h3>How to determine the volume </h3>
The following data were obtained from the question:
- Mass of methylergonovine = 0.2 mg
- Density of methylergonovine = 0.8 mg/mL
- Volume of methylergonovine =?
Density = mass / volume
Cross multiply
Density × volume = mass
Divide both sides by density
Volume = mass / density
Volume = 0.2 / 0.8
Volume of methylergonovine = 0.25 mL
