Answer:

So if the histones are not properly binding to the DNA then the DNA will not be able to condense into chromosomes, which it needs to do for mitosis to occur. So basically, mitosis will not occur.

Fossils almost never contain DNA. So how can we know how closely or distantly related fossil organsims are to living organisms
Nostrana [21]
While it's true that Fossils hardly even contain DNA, they can still provide numerous clues in order to identify and verify an organism.

For example, in terms of Dinosaurs, their bones and fossils have provided enough evidence to provide an evolutionary link with modern birds.

Carbon dating is another way to find the age of a fossil which provides more information on it's surrounding habitat and the animals it interacted with.

An enzyme contains a catalytic histidine residue in its active site that must release an R group proton to solution in order to
hjlf

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.

Which substance has the lowest specific heat?
skelet666 [1.2K]

Answer:

Metals such as iron have low specific heat. It doesn't take much energy to raise their temperature. That's why a metal spoon heats up quickly when placed in a cup of hot coffee. Sand also has a relatively low specific heat.
