<h3><u>Answer;</u></h3>
Adaptation
<h3><u>Explanation;</u></h3>
- Adaptation refers to the process in which animal or plant species becomes fitted to the environment. This occurs as a result of genetic changes or mutations.
- Adaptations may be, behavioral, psychological or structural. Behavioral adaptations are responses made by an organism which help it to survive.
- Psychological adaptations are body processes that helps and organism to survive or reproduce, while structural adaptations are features of the body of organisms which helps it survive or reproduce.
When particles are heated they expand
Answer:
ε = 201.5
Explanation:
Given data-
mass of benzene = 25.8 mg
= 25.8×10^-3 kg
Atomic mass of benzene= 78.11 amu
volume of hexane = 250.00 ml = 0.2500 L
Absorbance = 0.266
Length of the cell = 1.00 cm
Hence concentration =
solving we get
= 0.00132 M
Formula:
A= εcl
A= absorbance
c= concentration and l= length of cell
now substituting values in the above formula
0.266= ε×0.00132×1.000
⇒ε =
⇒ε = 201.5
Enzymes and proteins are extremely susceptible to pH changes which causes them to denature (lose the shape that gives them function). This denaturing is permanent for enzymes. A slight pH change could severely damage organ systems reducing there efficiency or completely halting their processes.
