Answer:
<em>A population is a distinct group of individuals.</em>
Explanation:
population is a distinct group of individuals, whether that group comprises a nation or a group of people with a common characteristic. In statistics, a population is the pool of individuals from which a statistical sample is drawn for a study.
A minority of crosswalks require audible beaconing, in which the sound source provides directional orientation. Where audible beaconing is activated, the volume of the WALK indication and the subsequent locator tone, or just the locator tone during the called pedestrian phase is increased and may be operated in one of the following ways:
<span>Increased sound comes from the far end of the crosswalk, as pedestrians cross the streetThe louder locator tone comes from both ends of the crosswalk, orthe louder locator tone is broadcast from an additional pedhead mounted speaker aimed at the center of the crosswalk</span>
Audible beaconing speakers must be oriented in line with the relevant crosswalk.
<span>If the speaker is not carefully oriented, the signal may give ambiguous information about which street has the WALK interval, and ambiguous information for traveling straight across the street.Beaconing is enhanced by the presence of a locator tone that users can home in on as they approach the destination corner, island or median having an accessible pushbutton.</span>
See Chapter 6, Designing Installations, for additional recommendations regarding audible beaconing.

Answer:
What is obtained by putting a bunch of muscle cells together is muscle tissue (option c).
Explanation:
Cells are the basic units that constitute living beings. These cells have the ability to differentiate and associate to form tissues.
Muscle cells are specialized cells, with contractile capacity, which when united form the muscular tissue, from which the striated and smooth musculature of the internal organs is formed.
Cells form tissues, these form organs and the set of organs constitute the different apparatuses and systems of the organism.
The other options are not correct because:
- <em><u>Heart
</u></em><em>: is a specialized organ formed from heart muscle tissue.</em>
- <u><em>Circulatory system</em></u><em>: is a set of organs and structures, responsible for the circulation of blood. It includes the heart and blood vessels.
</em>
- <u><em>Molecule</em></u><em>: corresponds to the molecular level of matter, formed from the association of atoms.</em>
