Answer:
D
Explanation:
It would be D because it would increse yes in population because the panthers are decreasing and attacking less. But, it would still level off because there are other predators who can kill the white tailed deer. Also the panther who is endangered could still atack even though theres just a few left that does not affect them from attacking. So it would increase but it would still level off.

I found on internet may be it helps
Explanation:
Here, we provide a general review of recent studies into the genetic basis of human brain evolution. The insights gleaned from these studies can be broadly divided into three categories: (i) positive selection on protein-coding regions of the genome that lead to changes in the sequences of existing proteins; (ii) duplication and deletion of genes; and (iii) evolutionary changes in non-coding regions of the genome, especially those in cis-regulatory sequences that lead to altered gene expression .
Answer: During a phase change, such as melting or boiling, the kinetic energy increases.
Explanation:
Kinetic energy is the energy obtained by the molecules of a substance due to their motion.
When phase change such as melting or boiling takes place then it means heat is absorbed by the substance. As a result, their molecules more even more rapidly from one place to another due to which more number of collisions take place.
Hence, a change in phase of substance occurs as kinetic energy increases in melting or boiling process.
Thus, we can conclude that during a phase change, such as melting or boiling, the kinetic energy increases.
The theoretical yield is calculated as follows
write the equation for reaction
that is 2 Zn + I2 ------> 2 znI
then find the moles of Zn used
moles= mass/molar mass
= 125/ 65.4 = 1.911moles
by use of mole ratio between Zn to Zni which is 2:2 the moles of ZnI is also= 1.911moles
theoretical yield is therefore= moles of ZnI x molar mass of znI
= 1.911 moles x 319.2 g/mol = 609.99 grams
We need balnce equation first
- Here Silver Nitrate is more
- So AgNO_3 is the excess reagent.
Note:-
Excess reagent is always present in reactant side
