A client with a long history of cardiovascular problems, including angina and hypertension, is scheduled to have a cardiac cathe

Tju [1.3M]

The nurse will explain to the client is the catheterization will visualize the disease process in the coronary arteries. A cardiac catheterization delivers information on how well a heart works, recognizes problems and allows for procedures to open blocked arteries.

For example, during cardiac catheterization your doctor may:

Gather up samples of blood to measure the oxygen content in the four chambers of your heart.

Take X-rays using contrast dye injected over the catheter to look for narrowed or blocked coronary arteries. This is known as coronary arteriography or coronary angiography.

Assess the ability of the pumping chambers to contract.

Look for deficiencies in the valves or chambers of your heart.

Execute a percutaneous coronary intervention (PCI) such as coronary angioplasty with stenting to open up narrowed or blocked segments of a coronary artery.

Check the compression in the four chambers of your heart.
Remove a small piece of heart tissue to examine under a microscope (biopsy).

The cell membrane is made up of many different kinds of proteins. These proteins can be classified as either peripheral, transme

joja [24]

Answer: Cell membrane has many properties which is stated below.

Explanation:

The cell membrane allow one cell to communicate with other cell. It is the cell membrane which is directly in contact with the cell membrane of the another cell.

The cell membrane also serves as a channel for the transport of materials from the outside to inside and vice versa.

It also provides stability to the cell. It combines with the carbohydrates and provides immune response and cell recognition.

Wind is caused by which of the following?

Paraphin [41]

C. The uneven heated of Earth's different surfaces. For e.g., land changes temperatures quicker as compared to the sea.

When the sun comes up, the land heats up quicker than the sea. As a result, air above the land will also heat up more than air above the sea. As hotter air rises from the land, the cooler air travels to the space which the hotter air rose from. This creates wind, or a cycle of air currents.

Hope this helps! :)

P.S. By the way, this seems to be more so of Geography as compared to Biology. :) No worries though!

In a population of 10,000 individuals of Monstera deliciosa, four individuals have a variegated phenotype that is caused by the

Mariulka [41]

Under the assumption of this population being in Hardy-Weinberg equilibrium, the probability for the fixation of the var recessive allele equals 0.02 = 2%

--------------------------------

Available data:

N = 10,000 individuals ⇒ Large population

4 individuals have a variegated phenotype

variegated phenotype is caused by the recessive var allele

No selection, no additional mutation ⇒ we can assume Hardy-Weinberg equilibrium

We need to know the probability for the fixation of the var allele.

We assume that the population is in Hardy-Weinberg equilibrium, so there should be no evolution.

Since the population is in H-W equilibrium, the allelic, genotypic and phenotypic frequencies will remain the same generation after generation.

Now, we will calculate the allelic and genotypic frequencies of variegated individuals in the population.

There are 10,000 individuals, and only 4 have variegated.

So, the phenotypic frequency, F(Var) is 4/10,000 = 0.0004 = 0.4%

Since this is a recessive phenotype, this value equals the genotypic frequency, F(vv) = 0.4%

Finally, we can get the allelic frequency by taking the square root of this value.

F(vv) = q² = 0.0004

f(v) = q = √0.0004 = 0.02 = 2%

According to these calcs, the probability for the fixation of the var allele is 2%, and the probability that all individuals express the variegated phenotype is 0.4%.
