Answer:
0.0025micrometer.
Explanation:
To calculate the actual size of the image, the formula to be used is
Actual size=Image size÷magnification.
The image size is 0.00005 wide
Magnification is 2000
First, convert the image size to micrometer.
=0.00005 × 1000000
50micrometers.
Actual size= 50÷2000
Actual size = 0.0025
Answer:
<u>a) strong joints with restricted movement.</u>
Explanation:
Joints which are closely fitted cannot allow free movement because movement requires space in the joint so the bones can move in this space. So a closely fitted joint allow restricted or no movement at all. Weak joints with restricted movements are called weak because they are not well fitted closely. Strong joints with restricted movement is closely fitted, one of the example is joints of skull.
Answer:
The similarities that can be seen in the members of kingdom plantae and plankton is that both of them perform photosynthesis.
These organisms provide oxygen and food to the other members. These members get energy for living their life.
The planktons and the members of kingdom plantae requires nutrients for their growth and development.
The differences that can be seen in the plankton and members of plantae is that plankton are found on the surface of water.
The members of plantae can be found on the land, on the surface of water. But some of the species like brown and red algae are found in the depth of sea or ocean.
Answer:
<em>The correct option is C) direction of force</em>
Explanation:
In the terms of physics, force can be described as a push or pull on an object which allows the object to either move forward or backwards or in other directions.
When Dr. Jeff uses the fire extinguisher of the skateboard to move forward, he will require the same force to move backward but in the opposite direction. Hence, for moving backwards, the only thing required by Dr. Jeff to move backwards will be the direction of the force.
