Speciation in a deer population as a result of geographic isolation
Answer:
D. Mitochondria are large enough to be seen with modern light microscopy, and can occupy as much as 20% of cytoplasmic volume.
Explanation:
Mitochondria are oval shaped organelles responsible for cellular respiration.
One of their defining characteristics
is the influx of protons from the mitochondrial membrane that enables ATP synthesis.
Mitochondria are known as the power house of the cell.
Structurally, mitochondria are spherocylindrical with a length of 2 microns and a diameter of 1 micron.
The oceanic crust is pulled under, which forms a subduction zone. Hope this helps.
Answer:
True
Explanation:
It is correct that body waves travels through the middle of the earth and surface waves travels along the surface.
- Seismic waves are elastic waves that are produced when the earth is disturbed.
- There are two categories of the wave which are body and surface waves.
- Body waves are the P and S - waves that travels through the earth.
- Surface waves are the love and Rayleigh waves which moves on the surface.
Answer:
All energy in the system are either potential or kinetic.
Option A to D are true
Explanation:
Kinetic Energy is the energy in a body when the body is not at rest (i.e. when it is in motion)
Whole
The potential energy of an object is energy of the body in a stored form. This means that when the body is at rest (not moving but waiting to do work). This is seen in Option A where the ball is held motionless above the floor.
The potential energy of a body decreases when the body moves downward and the kinetic energy increases. This is seen in Option B and C.
The last option D is supported by the first law of thermodynamics, also known as Law of Conservation of Energy, which states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another. The potential e ergy of the body when held motionless above the floor is equal to the kinetic energy of the body when it hits the floor.
