EleoNora [17]

Answer:

convergent evolution.

Explanation:

When organisms of distantly related species or groups are found in similar environmental conditions, they develop some similar features which are otherwise not present in their ancestral species. This is called convergent evolution. Convergent evolution also results in the development of similar traits in the distantly related organisms that are found in distantly located geographical regions having similar environmental conditions. Therefore, the presence of the same features in rodents and flying squirrels represent convergent evolution.

Veseljchak [2.6K]

Answer: It was obtained 8515 years ago

Explanation:

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

t = age of sample

a = let initial amount of the reactant

a - x = amount left after decay process  

a) to find the rate constant:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

t_{\frac{1}{2}}=\frac{0.693}{k}

k=\frac{0.693}{5760}=0.00012years^{-1}

b) for completion of 36% of reaction

t=\frac{2.303}{k}\log\frac{100}{36}

t=\frac{2.303}{0.00012}\log\frac{100}{36}

t = 8515 years

The time was 8515 years.
