An enzyme that follows simple michaelis–menten kinetics has an initial reaction velocity of 10 μmol⋅min−1 when the substrate con
svet-max [94.6K]

The Vmax of the enzyme is 12 μmol⋅min−1

We use Michaelis-menten equation,  which is given by;

V=\frac{Vmax(S)}{Km+(S)} \\

Where v is velocity of reaction

Vmax = maximum rate achieved by the system

[S] = concentration of a substrate

K_{m}= Michaelis constant

Given V_{0} = 10umolmin^{-1}

[S] = 5km

Now, we calculate Vmax:

10umolmin^{-1} = \frac{Vmax*(5Km)}{Km+5Km}

Km = 1

10=\frac{5KmVmax}{6Km}

\frac{10*6}{5} =Vmax

Vmax =12 μmol⋅min−1

During meiosis, sister chromatids are separated and move toward opposite ends of the cell as the centromeres that hold them sepa
julsineya [31]

Telophase II begins after the separation of sister chromatids. In this phase individual chromosomes reach at pole. Nuclear membrane starts getting formed around them and cytokinesis takes place. Cytokinesis is the division of cytoplasm.

This results in the formation of four daughter cells which are haploid.

Select all that apply. Which of the following are not properties of enzymes
AlladinOne [14]
Enzymes are proteins that are biological catalysts

They reduce the activation energy required for a reaction to occur and thus speed up a reaction

Temperature, above a certain point (optimum temperature) causes them to break down and they are gradually destroyed (denaturing)

They work best at a particular pH (optimum pH) and are once again destroyed by low or high pH's

They have a specific shape, with one particular part, known as the active site, that is specific to the substrate they speed the reaction of. These means they are specific to one type of reaction.

They aren't used in the reaction so they're re-usable.

If it isn't one of these then it is not one of the properties of enzymes

The Hawaiian state bird, the Nene, has an uncertain evolutionary history. It is thought that it has evolved from some other type
lana66690 [7]

Answer:

It will address the research question of what type of goose (species) does the Nene evolved from.

Explanation:

Genomics uses the whole set of an organisms DNA to study and understand its' function, structure, and evolution. Scientists will use the Nene's genome set to study its evolution,basically telling a story where it comes from.
