It is the Iris I believe. It controls the diameter and size of the pupil, controlling the amount of light reaching the retina.
Answer: They are called Moraines
Explanation: A glacier is a large body of ice originating from land that constantly moves slowly over land. It occurs in almost all parts of the world and makes up about 3/4 of fresh water all over the world.
Glaciers constantly move on land and they do this under their own weight.
As a glacier moves across land, it pushes soil and rocks in front of it and to the sides of it.
The resulting hill formed as a result of this soil movement is called a Moraine.
A moraine is sometimes referred to as a glacial till. It is an accumulation of materials (usually soil and rock) left behind by a moving glacier.
In order to prepare for division the cell has to Replicate DNA
Answer:
Transporting Electrons
As the high-energy electrons are transported along the chains, some of their energy is captured. This energy is used to pump hydrogen ions (from NADH and FADH2) across the inner membrane, from the matrix into the intermembrane space. Electron transport in a mitochondrion is shown in Figure below.
Explanation:
The answer should be NEURONES (nerve cells).
Neurons transmit electrical signals called NERVE IMPULSES from the cell body through the axon to the end plate. The junction between the end plate and the adjacent cell is called SYNAPSE. impulses passes through the synapse by diffusion of chemicals.
