A. a wide variety of hunting techniques
Explanation:
To help the fisher population to survive in a changing environment, they have to develop a wide variety of hunting techniques.
The new fisher population have to develop a wide range of strategies to satisfy its carnivorous instincts.
- Most predators are carnivores with a wide range of hunting skills
- They must be fast, subtle, good sighted and well adapted body part to hunt of preys.
- As they transcends different environments, they must have good and diverse hunting skills to give them a competitive advantage.

Answer:
At the end of each organ system you will need to make a summary of that ... So how does the food we eat eventually get to our cells in a small enough form ... The circulatory system is responsible for transporting blood with oxygen (O2) ... the digestive system to the cells in the body and remove waste products to be excreted.
hope this helps!

Answer:
Empirical formula is C₃H₃O.
Explanation:
Given data:
Mass of compound = 0.519 g
Mass of CO₂ = 1.24 g
Mass of H₂O = 0.255 g
Empirical formula = ?
Solution:
%age of C,H,O
C = 1.24 g/0.519 × 12/44 ×100 = 65.5%
H = 0.255 g/0.519 × 2.016/18 ×100 = 5.6%
O = 100 - (65.5+5.6)
O = 28.9%
Number of gram atoms of H = 5.6 / 1.01 = 5.5
Number of gram atoms of O = 28.9 / 16 = 1.81
Number of gram atoms of C = 65.5 / 12 = 5.5
Atomic ratio:
C : H : O
5.5/1.81 : 5.5/1.81 : 1.81/1.81
3 : 3 : 1
C : H : O = 3 : 3 : 1
Empirical formula is C₃H₃O.
