valentinak56 [21]

Definition:

Having two different alleles of a particular gene or genes.

(an Allele is a variant form of a gene.)

Simplification:

If the organism has one copy of two different alleles, it is heterozygous.

Eg: T and t

<em> </em><em> </em><em> </em><em> </em><em> </em><em>(</em><em>T</em><em> </em><em>for </em><em>tall</em><em> </em><em>and</em><em> </em><em>t</em><em> </em><em>for</em><em> </em><em>short</em><em>)</em>

Example:

<u><em>Pea</em><em> </em><em>Plants</em></u>

Pea plants can have red flowers and either be homozygous dominant (red-red), or heterozygous (red-white). If they have white flowers, then they are homozygous recessive (white-white). Carriers are always heterozygous.

T/F While paper clips are clinging to a bar magnet, they are temporary magnets.
steposvetlana [31]

Answer:

The answer is True

Explanation:

Temporary magnets can be created when they come into contact with permanent magnets, but they do not retain their magnetism. For example, if you rub a piece of iron along an existing magnet, within the iron's atoms the electrons align in a north-south direction and the iron becomes a temporary magnet. It will behave as a magnet and attract other ferromagnetic metals. If one paper clip is hung from a magnet, a second paper clip can be hung from the first, and a third from the second. However, when the magnet is removed, the paper clips will no longer act as magnets.
