Energy is started from the sun, with 100 percent of the energy given to plants. when the plants are eaten, only 10% of that energy is given to the animal, like a rabbit. When the rabbit is eaten by a larger predator, only 10% is given of the rabbits energy. This continues, so to find the amount of energy within a certain organism you would need to calculate 10% from each original source of energy

What unique characteristic does the bonding of carbon to other atoms have and why is this important for organic molecules?

Agata [3.3K]

Explanation:

The carbon atom has unique properties that allow it to form covalent bonds to as many as four different atoms, making this versatile element ideal to serve as the basic structural component, or “backbone,” of the macromolecules. Individual carbon atoms have an incomplete outermost electron shell.

The correct option is this: HAVE YOUR PARTNER APPLY MANUAL STABILIZATION WHILE YOU APPLY A LOOSELY BANDAGED ABSORBENT DRESSING.
Stabilization is a process that is used to prevent shock in injured or sick people. Stabilization should be the first thing that is done for a patient when a patient is in shock. To manually stabilize a patient with neck injury; place your hands on both side of the person's head and do not attempt to align the head and the lower body.

Elan Coil [88]

Answer:

Option-D

Explanation:

Parkinson's diseases are a neural disorder which affects the movement of the human body. The disease is caused by the low production or no production of dopamine by the neurons which thus interfere with the impulse transfer and thus movement.

In the given question, the patient with Parkinson's disease is provided with levodopa but no improvement is observed therefore the prescriber must change the drug regimen, for example, the levodopa should be given in combination with carbidopa. These medications enter the blood-brain barrier and get converted to the dopamine.

Thus, Option-D is the correct answer.

IceJOKER [234]

Answer:

Explanation:

The net movements of water from the region of higher water potential to the region of low water potential through a selectively permeable membrane is osmosis. It is a form of diffusion which involves the transport of water molecules.

In this present scenario water molecules pass through the selectively permeable membrane from higher water potential in the body, to lower water potential but high solute potential (Epsom salts). The later is called an hypertonic solution,this is because it has higher solute potential ,thus higher salt concentration than the surrounding medium,therefore water pass by osmosis into the Epsom salts.

If one is placed in this solution,the cells shrink as they lose water to the more concentrated Epsom.(hypertonic solution)

However, the body homeostatic mechanism through the kidney ensure re-absorption of fluid back to the body from the DCT and CT, via anti diuretic hormone to preserve the cell and the person.
