Explanation:
The myosin head rotates, causing overlap
with actin.
The myosin head attaches to a binding site
on the actin filament.
The myosin head detaches from one
binding site and reattaches to another.
Vestigial structures. These are structural elements that once served a purpose but as the organism evolved now serves no purpose.

Yes, plants are absolutely alive. They may not be conscious, sentiment beings, but they still perform cellular respiration, make waste products, and generate biomass (get bigger).
Hope this helps.
Answer:
The distance between them is changing at the speed of 10.16 m/hr
Explanation:
Consider the sketch attached below.
The question is simply asking to calculate the resultant of the two velocities.
To get the angle between them, we simply use the coordinates of the two vectors to determine the angle between them.
90 + 45 = 135°
from the cosine rule we have
= 
+ 
- 2abcosθ
= 
+
- 2 ×6×5×cos 135
= 103.426
c = 
c = 10.17 m/hr
