Answer:

Scientists believe that at first these bears scavenged seal carcasses that had washed ashore, and gradually began to hunt the seals by waiting at the water's edge as the seals surfaced to breathe. This is believed to be an important step in the evolution of a new bear species, the polar bear

Over time the new polar bears were used to the cold climate and learnt how to fish, they then separated from the grizzly bears, they developed new creatures which would help them survive in one of the most dangerous climate.

HOPE THIS HELPS :D!!!!!!

A client is being prepared for discharge from an ambulatory surgical clinic after a cataract extraction and an intraocular lens
lesya692 [45]

Answer: The correct answer to the question is option 1

I SHOULD CALL THE CLINIC IF MY EYE BEGINS TO HURT.

Explanation: Cataract is the opasity or clouding of the lens of the eye making it to deviate from it's normal natural transparent/clear form.It is characterised by blurry vision.Treatment of cataract is by removal of the opaque cataract and replacing it with an clear artificial lens.

Cataract extraction and intraocular lens implant is a generally safe procedure,so when pain occurs after the procedure,it indicates that infection has set in or there is bleeding in the procedure site and it is advices that when a patient notices any of these,it should be reported immediately. Certain things should be avoided after cataract extraction and intraocular lens implant, things like soap,having a bath,washing the hair can all irritate the eye so all these should be avoided from few days to atleast 2weeks after the surgery.

When the patient that has undergone cataract extraction and intraocular lens implant experiences flashes of light,it indicates they there is retinal detachment,this is not expected, but if it is experienced by the patient,it should be reported immediately too.

As mentioned earlier, cataract extraction and intraocular lens implant is generally a safe procedure and rapid improvement in vision is always recorded in some people although some other patients stay several weeks before they achieve an improvement in visual acuity.

Match the following. 1. the basic building block of all forms of life resolving power 2. the idea of Schleiden and Schwann that
Roman55 [17]

Answer:

1. Cell

2. cell theory

3. Organismal theory

4. resolving power

Explanation:

The cell is the smallest known unit of all living organisms. They are called the building blocks of life. An organism can be unicellular (made up of one cell) or multi-cellular (made up of many cells).

2. Cell theory was formulated and developed  by Schleiden, Schwann, and Virchow. They are considered as the basic principles of biology.

It states:

1. Living organisms are made up of cells.

2. Cells are the basic unit of life.

3. Cells are formed from pre-existing cells.

4. Energy flows inside the cell.

5. DNA is passed on from cell to cell.

6. All cells have the same basic chemical composition.

3. Organismal theory is the intended counter-argument of the cell theory. It was developed by Reichert, Strasberger, Sherrington, and Pavlov. It argues that the basic unit of life is the organism itself, suggesting that an organism came about from a cell that expanded.

4. Resolving power is the ability of an optical instrument like a microscope or a telescope to view objects that are close together as separate, abling the viewer to distinguish the two from each other.
