Physical change. Boiling water does not change the fundamental properties of the water, as it can turn back into water during condensation.
Answer:
total amount spent on student ticket = 186($2.5)=$465.00,
Total amount spent on adult tickets = 135($3.5)=$472.50
Explanation:
cost total = student ticket price (x) + adult ticket price (321 - x)
$937.50 = (2.5)(x) + (3.5)(321 - x)
$937.50 = 2.5x + 1123.5 - 3.5x
x = 186, therefore 186 student tickets sold,
(321-x) = 321-186 = 135, therefore 135 adult tickets were sold.
total amount spent on student ticket = 186($2.5)=$465.00,
Total amount spent on adult tickets = 135($3.5)=$472.50
So the total amount spent on tickets was
$472.50 + $465.00 = $937.50
Answer:
accurately that is the answer
Explanation:
Population study in ecology is a broad topic to be studied, in order to answer this question we must know that .......
<h3>
Population
</h3>
A population, in Ecology, can be defined as a set of individuals of the same species that live in a given area in a given period of time. Individuals in one population are more likely to interbreed with each other than with organisms in another population of the same species.
<h3>
Population dynamics</h3><h3>
</h3>
Population dynamics is the study of how and why populations change in size and structure over time. Important factors in population dynamics include rates of reproduction, death and migration.
With this information, we can say that" Ecologists conduct population studies to understand population dynamics by investigating how the <u>number of individuals</u> increases or decreases over time.
<u />
<u>We can conclude that these studies in </u><u>Population dynamics </u><u>are of great relevance to visualize the characteristics of </u><u>populations</u><u>.</u>

Answer:
The events in chronological order are:
- Abrin is absorbed into the blood and enters the body's cells
- Abrin binds to ribosomes in the cytoplasm
- Abrin inactivates the 28S rRNA in the large subunit of the ribosome.
- Ribosomes are unable to add new amino acids to polypeptides
- Protein synthesis halts in many tissues
- Multiple organ systems fail
- Victim dies
Explanation:
Abrin is a toxic protein obtained from the seeds of Abrus precatorius, it is highly toxic, with an estimated human fatal dose of 0.1-1 microgram/kg, and causes death after accidental and intentional poisoning.
When ingested the abrin would enter the victim's body and travel through the blood and eventually enter a cell's cytoplasm (abrin is absorbed into the blood and enters the body's cells). Once there it would interact with the ribosomes and reacts with them on a molecular level (peptide bond catalytic enzyme) (abrin binds to ribosomes in the cytoplasm), which results in the ribosome exhibiting its toxic response to abrin (abrin inactivates the 28S rRNA in the large subunit of the ribosome). As a result of the ribosome reacting to abrin (ribosomes are unable to add new amino acids to polypeptides), protein synthesis within that cell is affected (protein synthesis halts in many tissues). Once multiple cells are affected by abrin the organ will exhibit its toxic response (multiple organ systems fail), and the victim would die.
