Answer: Lydia's answer is correct.
Explanation:
The solution used by Lydia is:
4/5 × 10 = 4 × 1/5 × 10
= 4 × 10/5
= 4 × 2
= 8
The above solution by Lydia is correct.
Given the question, 4/5 × 10, this will be:
= 4/5 × 10/1
Let's multiply the numerator first, this will be: = 4 × 10 = 40
The denominator will be: = 5 × 1 = 5
Therefore, 4/5 × 10/1 = 40/5
Now when we divide 40 by 5, we will get 8. Therefore Lydia is correct.
Answer: Fibrous pericardium and Serous Pericardium
Explanation:
The pericardium can be defined as the fibroserous sac( double layered) which covers the whole heart. The gap between two layers of serous pericardium is filled with serous fluid. This fluid protects the heart from external shocks.
Fibrous pericardium
This layer is the most superficial layer which consists of dense connective tissue. This layer of the heart protects it from over filling of blood, anchors the heart to the surrounding wall.
Serous pericardium
This layer provides lubrication to the heart by resisting the friction which occurs during the various type of heart function.
Answer:
Muscle Build and Building a tolerance
Explanation:
As you work out or even just moving excessively, your muscles tear in tiny amounts to heal the body sends cell to patch up that area over time the cells will just keep stacking up. This is where the tolerance comes in since their is so many cells built up its harder for them to "rip" It sounds like a huge rip but its more of a tiny little rip not even enough to hurt.(until the next day.)
