Answer:
1. D.) Structural Data
2. C.) Overproduction
Explanation:
1. Structural Data was used to determine the similarities between the two species.
2. In biological terms, overproduction means that a generation had more offspring than can be supported by the environment. In this case, its a stronger hatchling beating out the waker hatchlings.
The number of liters of 0.90% NaCl solution one can make from 470 milligrams of table salt is 52.22 mL (milliliters) or 0.0522 L (liters)
In order to determine volume (number of liters) one can make from 470 milligrams of table salt (NaCl)
First, we will convert the unit of concentration to grams per liter or grams per milliliter
From the question, the desired concentration is 0.90% NaCl (9 grams of salt per 1000 grams of solution)
Since the density of the NaCl solution is 1.0 g solution/mL solution, then
9 grams of salt per 1000 grams of solution means 9 grams of salt per 1000 mL of solution.
From the question, mass of the table salt = 470 milligrams = (470/1000) grams
∴ Mass of the table salt = 0.47 grams
Now,
If there are 9 grams of salt per 1000 mL of solution
Then, there will be 0.47 grams per mL of solution
∴ mL
mL
mL
mL
∴ There will be 0.47 grams per 52.22 mL of solution
Hence, the number of liters of 0.90% NaCl solution one can make from 470 milligrams of table salt is 52.22 mL (milliliters) or 0.0522 L (liters)

Answer:
0 kgm/s
Explanation:
The momentum of Bob while resting at the river is 0 kgm/s.
This is because the momentum of any object at rest is 0.
Momentum is the quantity of motion a body contains. It is mathematically expressed as;
Momentum = m x v
m is the mass
v is the velocity
So at rest, the velocity of a body is 0m/s and therefore, the momentum is O
