Answer: The probability that the two children have the disease is 1/16 or 6,25%
Explanation: If the disease only occurs in homozygous individuals and the parents have the trait but not the disease that means is a recesive allele and the parents are heterozygous for this trait.
According to proportions stablished by Mendel, when there is a cross between 2 heterozygous (Ss x Ss) indivdials the probability to obtain a homozygous recesive (ss) descendant is 25% or 1/4 as shown in punnet square below:
![\left[\begin{array}{ccc}&S&s\\S&SS&Ss\\s&Ss&ss\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D%26S%26s%5C%5CS%26SS%26Ss%5C%5Cs%26Ss%26ss%5Cend%7Barray%7D%5Cright%5D)
Taking into account that the condition of the first kid does not imply the condition for the second, it should be analyzed as 2 independent events.
1. First kid has 1/4 of probability have the dissease as shown in punnet square
2. For a second birth, child has the 25% chance to have the disease
The probability that both events to happen is the product of each event probabilty:
p = 1/4 * 1/4 = 1/16 or 6,25%

Explanation:
Opportunist are organisms that are found naturally in other living organism and only cause disease in the organism when its immune system is compromised for example HIV virus lowers immune system strength by reducing the amount of the CD4⁺ cells available thereby exposing the organism to attack from opportunistic organism such <em>Staphylococcus aureus. </em>The opinion that supports the statement is S.aureus is found in the nasal passages of many healthy people.
Carrying capacity is the paramount number of a particular species that the earth or ecosystem can hold while limiting factors are the biotic and abiotic factors that confines or limits the growth of the living organism.
More the amount of limiting factor, greater will be the number of growth of the organism as the raw materials to hold life would be enough to sustain these many number of organism. Therefore, limiting factor governs the carrying capacity of various organisms on earth.
