Answer:
a video that shows penguin species that have different mating dances
Explanation:
The question is incomplete as it does not have the options which are:
- a video that shows a large river that has penguin populations on both sides
- a video that shows penguin species that have different mating dances
- a video that shows a penguin that is laying eggs
- a video that shows penguins in a tidal pool and an open ocean
Answer:
a video that shows penguin species that have different mating dances
<em><u>The reproductive isolation is the factor which allows the species to evolve and form a new species, therefore, this factor is used to describe a species.</u></em>
<em><u /></em>
<em><u>The reproductive isolation refers to a mechanism in which the species are isolated to not interbreed with the individual of other species. The reproductive isolation could be due to behavioural, psychological, physical or genetic differences. evolved as an adaptation.</u></em>
<em><u /></em>
<em><u>In the given cases, the penguin species which shows different mating dances is considered to be reproductively isolated as the different dance rituals evolved as behaviour to prevent them from mating.</u></em>
<em><u /></em>
<em><u>Thus, the selected option is correct.</u></em>

The answer is a. correlational research.
In this scenario, you only do observation of one event and trying to find a link between them. This method is good for finding correlation, but not for causation.
Because you only observe the subject without intervention, it shouldn't be experimental research. What you observe is only one condition, so there is no control subject that get different condition.
Receptors that provide animals with information from the external environment are located in the:
- ears
- skin
- tongue
- eyes
- nose
These receptors are known as sensory receptors as they perceive the changes that occur in the external environment and transmit the information to the nervous system.
The name of these receptors located in the respective organ is as follows :
1. Ear - auditory receptor
2. Skin - mechano (cutaneous) receptors
3. tongue - taste receptors
4. eyes - Photoreceptors
5. nose - olfactory receptors
An example of how it detects the changes in the external environment can be understood as follows :
The substances that have odor produce chemicals known as odorants which bind to the olfactory receptors located in the nose which then produces electric signals which are transmitted via the nerves to the olfactory bulb in the brain and the smell is detected.
