A person has polydactyly (extra fingers or toes). Polydactyly is caused by a dominant allele.

Helen [10]

Answer:

1 I think, read the explanation.

Explanation:

Offspring need to carry just one dominant allele from their parents to inherit the polydactyl condition. The probability of the offspring having polydactyly is 50% (2 of the 4) and 50% not having it (normal). This can be expressed as a ratio, 2:2 which can be simplified to 1:1. - found on the internet

When a living organism dies, it stops taking in new carbon. Thus, as the radioactive carbon-14 decays, the ratio of carbon-12 to

Alexxandr [17]

Answer: The fossil is 11459 years old.

Explanation:

Half-life of carbon-14 = 5700 years

First we have to calculate the rate constant, we use the formula :

$k=\frac{0.693}{5700\text{years}}$

$k=1.21\times 10^{-4}\text{years}^{-1}$

Now we have to calculate the age of the sample:

Expression for rate law for first order kinetics is given by:

$t=\frac{2.303}{k}\log\frac{a}{a-x}$

where,

k = rate constant = $1.21\times 10^{-4}\text{years}^{-1}
t = age of sample = ?
a = let initial amount of the reactant = 100 g
x = amount decayed = 75 g
a - x = amount left after decay process = 100 - 75 = 25 g Now put all the given values in above equation, we get
[tex]t==\frac{2.303}{1.21\times 10^{-4}}\log\frac{100}{25}$

$t=11459years$

The fossil is 11459 years old.

Certain drugs may prevent the unregulated reproduction of cells. Which process was the

const2013 [10]

Answer:

Cell Division

Explanation:

Cells reproduce by the process of CELL DIVISION, which is the formation of an increased number of cells from a single parent cell. Mitosis is the type of cell division used for the multiplication of cells as it involves the synthesis of two identical number of daughter cells from a single parent cell.

However, certain drugs that may prevent the unregulated reproduction of cells is trying to directly affect the process of cellular division in that cell. This is because cell division is the way through which cells reproduce themselves.
