The answer is 44 chickens and 28 rabbits.
We have a system of two equations.
x - the number of rabbits
y - the number of chickens
Both chicken and rabbit have only 1 head, so the first equation is: x + y = 72.
Since rabbits have 4 legs and chickens 2 legs, the second equation is: 4x + 2y = 200.
Now, let's solve the system:
x + y = 72
4x + 2y = 200
___________
y = 72 - x
⇒ 4x + 2 · (72 - x) = 200
4x + 2 · 72 - 2 · x = 200
4x + 144 - 2x = 200
2x + 144 = 200
2x = 200 - 144
2x = 56
⇒ x = 56 ÷ 2 = 28
So, there are 28 rabbits.
Since
y = 72 - x = 72 - 28 = 44,
there are 44 chickens.
I believe the first answer is #4 and the second is #1. Please correct me if I am wrong.
Answer:
Water cycle is also called hydrological cycle. In this cycle water moved continuously above the surface of the earth for the continuity of life. Water is evaporated from the sea and ocean in the process of evaporation. This water goes to the atmosphere and form clouds. These clouds moves to hilly areas and comes to the ground in the form of rainfall and snowfall etc. Some water is stored on the mountains in the form of snow and the remaining downward through streams.

Answer:
Species A: 2
Species B: 56
Species C: 162
Explanation:
Codons are sequence of 3 purine or pyrimidine bases that codes for amino acids. Each codon in mRNA eventually binds with anticodon in tRNA during protein synthesis and gets translated into their respective amino acids. Hence, the number of amino acids in each of the species represents the minimum number of codons in each species.
<em>Therefore, species A with 2 amino acids will have a minimum codon length of 2, species B with 56 amino acids will have minimum of 56 codons while species C with 162 amino acids will have minimum codon length of 162.</em>
