Answer:
Much of the coordination of vertebrate body functions via chemical signals is accomplished by the brain
Explanation:
The central nervous system which makes up the brain and spinal cord coordinates body functions of vertebrates via chemical signals through the nerve cells
Every single one here looks correct except for the last one involving algae, frog, and rabbit considering they are organisms, therefore it should be organism.
Answer:
4780.3 cm^3
Explanation:
A cone is a three-dimensional shape and its volume can be calculated using the formula:
V = 1/3 πr^2h or πr^2h / 3
Where V= Volume of cone (cm^3)
r= radius (cm)
h= height (cm)
π= constant (22/7)
In this question, the values of r and h are 13cm and 27cm respectively.
Hence, to calculate the volume of the cone, we say;
V = 1/3 × 22/7 × 13 × 13 × 27
V = 100,386 / 21
V = 4780.2857142857
4780.285 to the nearest tenth is ~ 4780.3
Therefore, 4780.3cm^3 is the volume of the cone.
