Where:

• $E$ = Energy

• $m$ = Mass

• $c$ = Speed of light in a vacuum

Explanation

Explanation

Transverse waves involve oscillations perpendicular to the direction of travel and can be polarized, while they do not necessarily require a medium to travel (e.g., light waves).

Explanation

 Non-invasive Genetic Sampling:

This method involves collecting genetic material (like DNA) from animals without direct contact, for example, through scat, hair, or shed skin.

Applications:

Species Identification: Identifying species based on genetic markers.

Individual Identification: Distinguishing between individuals within a population.

Population Size Estimation: Estimating the size of a population using genetic data.

Genetic Diversity Analysis: Assessing the genetic diversity and structure of populations.

Explanation

 Urial males have large horns, curling outwards from the top of the head turning in to end somewhere behind the head; females have shorter, compressed horns.

The horns of the males are up to 100 cm (39 in) long.
