Explain why the change you made caused the stingwing population to decrease. Use energy storage molecules to explain your answer.
Answers
Answer:
Reprduce
Explanation:
The decrease in the stingwing population was caused by the change in energy storage molecules. Stingwings rely on energy storage molecules, such as glycogen and fats, to fuel their activities and survival. If the change disrupted their ability to store and utilize these molecules, their energy levels would decrease, leading to decreased population size.

HELP! 100 POINTS! A cinder block is pulled 0.50 meters to the right in 3 seconds. What is the block's average speed to the nearest hundredth of a meter per second (m/s)?
Answers
The average speed of the blocks are 0.36 m/S.
Explanation:
Average speed is defined as the ratio of distance covered per unit time. So if it is said that blocks are pulled to 0.9 m in the right side. This means the blocks cover a distance of 0.9 m from the origin and that distance is covered in 2.5 s. Thus, the average speed can be calculated from the change in speed
with respect to time. As at time t = 0, the speed is
also zero, and at time t = 2.5 s, the speed will be
Speed =
0.9 = 0.36
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.
2.5
Since, in this case, the speed is equal to the average speed of blocks. So the average speed of the blocks will be 0.36 m/s.

40.3 for the unit that represents the minimum amount of magnesium oxide I beilieve.
Explanation:
Magnesium atoms are heavier than oxygen atoms, so we expect more than 50% of magnesium in the weight composition. Taking just one atom of Mg and one atom of O you will get a mass of 16.0 + 24.3 = 40.3.

Why is it easier for most metal elements to gain electrons rather than to lose them?
PROPER EXPLANATION
Answers
Because it is easier for metals to shed their valence electrons and form cations for a stable configuration, they have comparatively few chances of acquiring electrons.
The metals usually complete their octet in each reaction. The outermost electron shell often contains more electrons in metals. Metal atoms lose electrons when they interact with other non-metals because the energy of an electron in its outermost shell is very weak.
Metals often have low ionization energy because their electrons are positive in nature. Metals lose their electrons and trade them with non-metals to achieve a stable configuration.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

3. A recent flood in the area has caused many short-term changes to
the ecosystem. Which is a long-term change?
A. Standing water in the streets and sewers
B. Temporary displacement of organisms
C. Permanent change in the landscape
D. Poor water quality in rivers and streams
Answers
Answer:
c
Explanation:
While standing water in the streets and sewers (option A) and poor water quality in rivers and streams (option D) may persist for some time after the flood, they are generally considered short-term changes as they can eventually be remedied through clean-up efforts and restoration programs.
Temporary displacement of organisms (option B) can also be considered a short-term change, as organisms will eventually return to their original habitats once conditions improve.
However, a permanent change in the landscape (option C) such as altered river channels, new water bodies, or changes in topography, can have lasting effects on the ecosystem and its inhabitants. These changes may alter habitat suitability, nutrient cycling, and water availability, which can impact the ecosystem for years or even decades to come.
Answer: C
Explanation:
The landscape could be flooded. Houses and buildings may be restricted.
(1.) If at 100.0 mL solution contains 0.850 moles of a solute, what is the molarity ?
(2.) If the molarity of a solution is 12 M and the volume of the solution is 1.0 L, how many moles of solute does the solution contain ?
Answers
Answer:
See below
Explanation:
1) Moles / volume
.85 mole / .1 liter = 8.5 M
2) 12 moles are contained in one liter
.85 mole / .1 liter = 8.5 M
2) 12 moles are contained in one liter
A sample of water is taken and kept in a beaker in a freezer at a constant temperature of 0°C. If the system is at dynamic equilibrium, which of these statements is true? The rate of freezing is equal to the rate of melting. The rate of freezing is greater than the rate of melting. The amount of ice is greater than the amount of water. The amount of ice is equal to the amount of water.
Answers
At dynamic equilibrium, the concentration of ice and water has been equal. Thus, option D is correct.
The equilibrium state can be given as the condition when the reactant and the product in the chemical reaction have been in equal amount.
In the condition when the water has bee kept in the freezer, the water will condense at the freezing temperature and will be converted to ice. The water there has been the reactant while the ice has been the product.
According to the law of equilibrium, at the equilibrium there has been equal concentration of reactant and products. Thus, at dynamic equilibrium, the concentration of ice and water has been equal. Thus, option D is correct.
