Use DNA from hair follicles of supposed zoo parents and of the supposed offspring to compare sequences amplified with primers for a highly polymorphic region.

DNA sequencing and comparison is a way for checking if two individuals are closely related. Comparison of the sequence of the parents to the supposed offspring will indicate if indeed there was a relationship or if it was imported.

Which is the best procedure of separating a mixture of maize bean and sugar

Olegator [25]

Answer:

here are several methods of separating mixtures. The common ones are:

1. Winnowing

The wind is used to separate wharves (chaff), small sticks, and dry leaves, from grains or seeds by blowing the chaff away.

Chaff is usually lighter than the grains.2. Sieving

a sieve is used to separate mixtures of particles of different sizes. For example stones from flour.

The larger particles remain on the sieve while the finer ones pass through.

3. Picking

Here the large particles are separated from smaller ones by observing them and using the hands to remove the unwanted ones.

For example, stones are separated from rice or beans in this way.

4. Filtering

This method is used to separate a liquid from particles that cannot dissolve in it.

For example, separating sand from water using filter paper or piece of cloth.5. Decanting

This is when a liquid is separated from large particles of solids by pouring the liquid out gently.

For example, pouring off kerosene that has mixed with tiny ball bearings.
