Answer:
Cerebral Nuclei.
Explanation:
Cerebral nuclei refers to one of three components of the cerebrum. It is a composite structure of the end-brain defined on the basis of origin from the ventricular ridge of the embryonic Encephalon. It is a lusters of gray matter that contain neuron cell bodies and lie within masses of white matter.
Answer:
C) The cell membrane allows water to enter and leave the cell.
Explanation:
The cell membrane is a selectively permeable membrane that allows certain non-polar and small substances to move through it. Water is allowed to move freely through the cell membrane according to the concentration gradient. After the removal of shells, the membrane served as the outer most covering of eggs.
When placed in a different solution, the water moved in or out of the cells depending upon the concentration gradient. If the egg cells were placed in a hypotonic solution, water will enter into the egg cell resulting in the increase in its volume. On the other hand, when an egg cell is placed in a hypertonic solution, water leaves the cell through the cell membrane and the egg shrinks. This passive movement of water through the cell membrane is called osmosis.
A Front is basically a boundary between two air masses ,and more like A Weather System.
A Pressure System is air being lifted instead of pressed down and The MOVEMENT of a cold front through a Warm Front is usually called a pressure System
Answer:
The correct answer is: on the side of the membrane that has a higher concentration of the cargo molecule immediately after a phosphate has been added to the carrier protein.
Explanation:
- A Carrier protein can be defined as an integral membrane protein that spans across the plasma membrane and is responsible for transporting molecules against the gradient of their concentration.
- A Carrier protein operates in the following manner:
- In the unphosphorylated state, the carrier protein remains open to that side of the plasma membrane which has a low concentration of the solute molecules.
- It binds to ATP (adenosine triphosphate) which causes it to bind to the solute molecules by increasing its affinity towards the solute molecules.
- This is followed by the phosphorylation of the carrier protein with a kinase enzyme using the bound ATP (adenosine triphosphate).
- This causes the carrier protein to have a conformational alteration that makes it open towards that side of the plasma membrane where the concentration of solute molecules is high.
- The phosphorylated form of the carrier protein has a low affinity towards the solute molecules and so it releases the solute molecules in that side of the membrane where the concentration of solute molecules is high.
- The phosphate group from the carrier protein is removed by a phosphatase.
- Now, the de-phosphorylated carrier protein again comes back to its original conformation and faces that side of the plasma membrane where the concentration of solute molecules is low.
The bird species has presumably adapted to the conditions after the forest fire if they're still alive. They might have found a new shelter to live at and foods to eat and make it durable for the time period remaining to keep surviving.
