Options missing:
a) The pH of the environment should be relatively high.
b) The pH of the environment should be relatively low.
c) The pH of the environment would not matter.
d) The environment should be set to the biochemical standard state.
Answer:
a) The pH of the environment should be relatively high.
Explanation:
For optimal function an enzyme needs a certain environment or condition. As temperature increases, the rate of enzyme activity also increases. As temperature increases toward its optimum point of 37 degrees Celsius (98.6 F), hydrogen bonds relax and make it easier for the hydrogen peroxide molecules to bind to the catalase.
The part of the enzyme where this reaction takes place is called the active site. A temperature that is higher or lower than this optimum point changes the shape of the active site and stops the enzyme from working. This process is called denaturation.
Enzyme pH levels also change the shape of the active site and affect the rate of enzyme activity. Each enzyme has its own optimal range of pH in which it works most effectively. In humans, catalase works only between pH 7 and pH 11. If the pH level is lower than 7 or higher than 11, the enzyme becomes denaturated and loses its structure. The liver sustains a neutral pH of about 7, which creates the best environment for catalase and other enzymes.
General acid catalysis would require histidine to be protonated at pH values (pH 8.0) optimal for enzymatic activity which is relatively high.
Because they have different Cones. Which simply means that some animals see certain types of colors or even Infrared or Ultraviolet, in which Humans cannot see.
A diverse population is usually more stable because it is better at resisting disease because of simple biology.
I’m pretty sure that is false
Answer:
The correct answer is : male : female = 1:2
Male percent = 33.33%
female percent = 66.66%
Explanation:
In this question, it is given that a lethal gene is carried by X chromosome which is recessive which means will cause death if both copies are recessive for this gene.
The cross between normal man and hybrid or heterozygous women
The gametes: XH and Y from man and XH and Xh from women where Xh is recessive letheal allele.
The cross:
XH Y
XH XHXH XHY
normal female Normal male
Xh XHXh XhY
Carrier female dead male
This explains that out of three offspring two will be females and one male. Thus the percentage will be:
Male : 1*100/3 = 33.33%
Female : 2*100/3 = 66.66%
