Answer:
1/16
Explanation:
Sickle-cell disease is caused by a homozygous recessive genotype <em>dd</em>.
A man and a woman both heterozygous Dd will have the following offspring:
The probability of having a <em>dd</em> child with Sickle-cell disease is 1/4. Each time they have children the gamete combination is random, so the genotype of the second child is independent from the genotype of the first child.
According to rules of probability, if two events are independent from each other, the probability of both happening is calculated by multiplying the individual probabilities of each.
Therefore the probability of having the first two children with the disease is 1/4 x 1/4 = 1/16.

Answer:
Vmax/ total enzyme concentration (Et)
Explanation:
According to the kinetics of Enzyme catalyzed reaction, the enzyme binds substrate and form the enzyme-substrate complex. The rate constant for this complex formation is K₁.
The enzyme complex later dissociates into the product and the enzyme itself ans the rate constant for this reaction is k₂. An enzyme-catalyzed reaction has the maximum velocity called Vmax.
The k₂ is also known as the turnover number which represents how many substrate molecules are converted into the products.
The mathematical expression for this reaction is the:
Vmax/ total enzyme concentration
Thus, Vmax/ total enzyme concentration (Et) is correct.
Its according to their organs.. where the my come from.. where they inhabit..what the eat.. how they look like..
take for example: reptiles.. they are classified as reptiles cause.. they are the only types of animals who have hard scaled skin not like fish..
