Explanation:
Answer:
56.5cm
Explanation:
Perimeter of rectangle = 2(l+b)
= 2(63/4+25/2)
= 2(63+50/4)
= 2(113/4)
= 113/2
= 56.5cm
Answer: 7cm
Explanation:
The surface area of a sphere is calculated by using the formula:
A = 4πr²
Since the surface area is 616cm², using the formula given, the radius will be calculated thus:
A = 4πr²
616 = 4 × 22/7 × r²
616 = 88/7 × r²
Multiply both side by 7/88
616 × 7/88 = 88/7 × 7/88 × r²
49 = r²
r = ✓49
r = 7
The radius is 7cm
Answer:
I would be the extension of the trunk
Explanation:
The erector spinae muscle extends the vertebreal column. [1] It is formed of 3 muscles and its fibers run more or less vertically throughout the lumbar, thoracic and cervical regions. It lies in the groove to the side of the vertebral column. In cervical region it is covered by nuchal ligament and in thoracic and lumber region by thoracolumbar fascia.
bacteria have the DNA as well as the tools (such as ribosomes and proteins) in order to reproduce themselves. While viruses only contain limited DNA and no not have the necessary tools.
bacteria reproduces asexually. a virus reproduces by invading a host cell casing the cell to make copies of the DNA(RNA). destroying the host cell and releasing the virus.
