Lizards are reptiles that are closely related to snakes. Like all reptiles, lizards have scaly skin and are ectotherms—cold-blooded animals whose body temperature varies with the temperature of their surrounding environment. Most lizards are native to the tropics, but a number of species are found in temperate regions.Chameleons, iguanas, skinks, monitors, anoles, and geckos are some of the many different types of lizards.
A number of lizard species have adapted to life in the desert. Some desert lizards have toes fringed with spiny scales to help them run across the sand without sinking. Others burrow into the sand to escape the desert's intense heat, to hide from predators, or to search for small animals that they prey upon. Some burrowing lizards even have clear scales on their eyelids that protect their eyes but still allow them to see while they move under the sand.

Explanation:
The given data is as follows.
= 211 nm, 
l = 1 cm, 7% < Transmittance < 85%
Suppose the aqueous solution follows Lambert-Beer's law. Therefore,
Absorbance = 
Hence, for 7% transmittance the value of absorbance will be as follows.
Absorbance = 
= 1.155
For 85% transmittance the value of absorbance will be as follows.
Absorbance = 
= 0.07058
According to Lambert-Beer's law.
A = 
where, A = absorbance
= molar extinction coefficient
C = concentration
Therefore, concentration for 7% absorbance is as follows.
= 
= 
= 0.187 mmol/L
Concentration for 85% absorbance is as follows.
= 
= 
= 0.01144 mmol/L
Thus, we can conclude that linear range of phenol concentration is 0.01144 mmol/L to 0.187 mmol/L.
Answer:
D because the grass is eaten by the antelope and the antelope is eaten bu the lion
Answer:
After 1326s, the concentration of pyruvic acid fall to 1/64 of its initial concentration.
Explanation:
The first order kinetics reaction is:
ln [A] = ln [A]₀ - kt
<em>Where [A] is concentration after t time, [A]₀ is intial concentration and k is reaction constant.</em>
To convert half-life to k you must use:
t(1/2) = ln 2 / K
221s = ln 2 / K
K = ln 2 / 221s
<h3>K = 3.1364x10⁻³s⁻¹</h3>
If [A] = 1/64, [A]₀ = 1:
ln [A] = ln [A]₀ - kt
ln (1/64) = ln 1 - 3.1364x10⁻³t
4.1588 = 3.1364x10⁻³s⁻¹t
1326s = t
<h3>After 1326s, the concentration of pyruvic acid fall to 1/64 of its initial concentration.</h3>
