Answer:
<em>A- The Archaea have cell membranes made of ether-linked hydrocarbons which branch, while Bacterial membranes are made of ester-linked fatty acids.</em>
IT IS POSSIBLE FOR PARTICLES WHICH A PREDOMINANTE POSITIVE VALENCE TO COMBINE WITH PARTICLES OF DISIMILER VALENCE FORM A NEW MOLECULE DISIMILAR FROM EITHER OF HOSTS.
Answer: The ball's velocity will increase
When a ball falls below the point of releasing its velocity increases. The falling of the ball is controlled by the two forces, the drag force and acceleration due to gravity. The acceleration due to gravity accelerates the ball in the downward direction at the constant rate. The drag force slows the ball when it falls below and it is a function of velocity so when the velocity of the ball increases so the drag force also increases.
B. the reason why scientists do he experiment more than once is because they have to compare the first attempt and the second attempt . Because if they are different they have to figure out what id the different or aka what is different. hope this helps ;)
