Answer:
1 Adult ticket=$35
1 Children ticket=$20
Step-by-step explanation:
21C+15A=945
6C+6A=330
we find adult tickets first
42C+30A=1890
42C+42A=2310
12A=420
A=35
we will find children ticket next
42c+30a=1890
30c+30a=1650
12c=240
C=20

Answer:
The birds are more likely to survive than the fish because the fish actually live in the lake and get resources from there. If the lake gets polluted, the water, oxygen, and food will get worse and the fish will slowly start to die. But the birds can just look for their resources somewhere else.
Answer:
The cave painting on the image is representing the animals, or rather the environment that was seen by the artists of the painting in their surroundings. We can see that there are wild horses depicted on it, but also a rhino. The wild horses were probably a prey animal, while the rhino was a respected animal and feared one, thus they were avoiding it. The artists that painted it were the Cro-Magnons, early Homo-sapiens in Europe, in what is now France. The reason why it was painted is probably because the artist wanted to depict the environment, but also maybe for teaching the youngsters about the animals from early age, so that they know which ones are to be hunted, and which ones to be avoided.
Classifying each label into the correct category of human red blood cell
A) Human red blood cell shrinks
- Cells placed in hypertonic solution
- More water moves out of cell
B) Normal Human red blood cell
- Cell placed in isotonic solution
- Water enters and leaves at the same rate
C) Human red blood cell swells
- Cell placed in hypotonic solution
- More water moves into cell
<h3>Types of solution</h3>
A hypertonic solution is a solution with a higher concentration to its surroundings ( i.e contains more solutes like electrolytes than its surroundings ). when a cell is placed in such solution is shrinks gradually and dies off through a process known as plasmolysis. while a hypotonic solution is a direct opposite of a hypertonic solution. Also An isotonic solution is a solution with the same concentration with its surrounding solution.
Hence we can conclude that the classification of each label into the appropriate category are as listed above.
