What caused the deer population to grow early on? A.) An abnormally cold winter caused offspring to die.
B.) A drought caused there to be less food and water available to the deer.
C.)The number of births was equal to the number of deaths in the deer population.
D.) The deer had a better food source so they had 2-3 fawns per year instead of 1 fawn
per year.

i think it is C but not 100% sure.

Explanation:

D) The deer had a better food source so they had 2-3 fawns per year instead  of 1 fawn  per year.

The other options show that the populations actually decreased, due to cold temperatures and droughts.

Let me know if this helps!

when 25.0 ml of 0.700 mol/l naoh was mixed in a calorimeter with 25.0 ml of 0.700 mol/l hcl, both initially at 20.0 °c, the temperature increased to 22.1 °c. the heat capacity of the calorimeter is 279 j/°c.

the equation for the reaction is:

naoh + hcl → nacl + h₂o

moles of hcl = 0.0250 l hcl ×

0.700

mol hcl

1 l hcl = 0.0175 mol hcl

volume of solution = (25.0 + 25.0) ml = 50.0 ml

mass of solution = 50.0 ml soln ×

1.00

ml soln

= 50.0 g soln

δt=t2-t1

= (22.1 – 20.0) °c = 2.1 °c

the heats involved are

heat from neutralization + heat to warm solution + heat to warm calorimeter = 0

q1+q2+q3=0

nδh+mcδt+cδt=0

δh=1025.22j0.0175 mol= -58 600 j/mol = -58.6 kj/mol

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
