C. Temperature and pH can affect how enzymes work

Enzymes show a maximum activity at an optimum pH and temperature. Changes in the pH or the temperature can cause damage in the structure of the enzymes, if the structure changes the substrate can no longer bind to the enzyme, which is why the activity of the enzymes starts to slow down.

Why do organisms have varying traits, like different colored eggs?
mylen [45]

the organisms have varying traits, like different colored eggs because of the natural selection.

<h3>What is the process of natural selection? </h3>

Natural selection is one of the main mechanisms of evolution. In a very simple way, we can say that natural selection is a process in which the fittest organisms are selected, survive in the environment, reproduce and pass their characteristics on to their descendants.

the color change of an egg occurs by natural selection and also by genetic variability. since the environment will select the best ones to survive and mutations will occur. Natural selection will forcefully change the environment causing only a few species to survive.

Answer:

The correct answer is - 6.8950.61 gm per mole

Explanation:

Given:

One form of hemoglobin is 0.324% Fe by mass

1 hemoglobin = 4 Fe

Solution:

Molar Mass of iron = 55.85

mass of 4 iron atom = 55.85 * 4 = 223.4 gms

0.324 % correspond to 223.4 gms

100 % correspond to = 223.4 *100/0.324

= 68950.61 gm

MM of haemoglobin = 68950.61 gms = 6.8 E4 gms
