CARDIAC CATHETERIZATION samples the blood in each heart chamber for oxygen content and pressure. Cardiac catherization is a medical technique that is often employed to diagnose and treat some cardiac conditions. The method makes use of a thin, flexible, tube [cather] which can be inserted into a blood vessel in the upper arm and threaded into the heart. Can also be used to check blood flow in the coronary arteries.

Warm surface waters get depleted of nutrients and carbon dioxide, but they enrich again as they travel through ________ waters i
Nonamiya [84]

Answer: Option B. "Deep"

Explanation:

Thermohaline circulation helps to drive the global conveyor belt, which is a global-scale system of currents. Due to the movement of ocean currents through different polar regions, it allows depletion of nutrients and carbon dioxide at surface waters and get enrich again as move through deep waters in the conveyor belt.

Winds in the ocean helps to  drive ocean currents in the upper ocean’s surface and these ocean currents moves below the ocean surface as well. the process that controls the movement of ocean current deep in the ocean is called Thermohaline circulation that  is based on differences in the water’s density,  and controlled by temperature (thermo) and salinity (haline).

Thermohaline circulation forms in the polar regions of Earth. Ocean water in the polar region gets colds that allows the formation of sea ice, which in turn make the surrounding seawater saltier and increases the ice density and sinks. This allows the deep-ocean currents to drive the Global conveyer belt.

The conveyor belt starts from the surface of North Atlantic pole, where seawater become saltier and ice starts sinking.  This deep water heads south along the western Atlantic basin. The conveyor belt get recharged as it travels along the coast of Antarctica and carries more cold, salty, dense water. The current get divided into two different sections, one traveling to the Indian Ocean and the other moves into the Pacific Ocean. The two sections of the current get warm and rises, as they travel northward, then turn back around  westward and southward.

The warmed surface waters continue to circulate around the globe and follows depletion of nutrients and carbon dioxide. But they get enrich again when they travel through deep waters all around the the  Global conveyer belt.

Hence, the correct answer is option is B "Deep".

A hybrid _____.
Serhud [2]

Answer: is heterozygous

Explanation: A hybrid is heterozygous which means that it has one dominant gene and one recessive gene. A dominant gene is a type of gene which has the ability to express itself phenotypically either in a homozygous or a heterozygous state. A dominant gene masks the effect of a recessive gene. A recessive gene is a type of gene that lacks the ability to express itself in a heterozygous state. It can only express itself outwardly in a homozygous state. It's effect is masked by the dominant gene is a heterozygous state.

A plastic bottle contains 32.5 L of gas at a pressure of 45.7 kPa and
Monica [59]

Answer:

Final pressure, P2 = 362.26 kPa

Explanation:

Given the following data;

Initial volume = 32.5 Liters

Initial pressure = 45.7 kPa

Final volume = 4.1 Liters

To find the final pressure, we would use Boyle's law;

Boyles states that when the temperature of an ideal gas is kept constant, the pressure of the gas is inversely proportional to the volume occupied by the gas.

Mathematically, Boyles law is given by;

PV = K

P_{1}V_{1} = P_{2}V_{2}

Substituting into the equation, we have;

45.7 * 32.5 = P_{2} * 4.1

1485.25 = 4.1P_{2}

P_{2} = \frac {1485.25}{4.1}

P_{2} = 362.26

Final pressure, P2 = 362.26 kPa
