Which of the following heart block dysrhythmias is identified by a repetitious prolonging PR interval pattern after each blocked QRS complex
a) first degree heart block
b) second degree heart block type I
c) second degree heart block type II
d) third degree heart block

Answers

Answer: Option A.

first degree heart block

Explanation:

First degree atrioventricular block is a condition that is associated with electrical condition system of the heart in which the electrical impulses is conducted from the cardiac atria to the ventricles via atrioventricular node in a slow manner compare to the normal transmission.

It is first degree great block because it is characterized by prolong PR interval on an electrocardiogram (ECG) to more than 200 msec and atrial impulse is transfered to the ventricles, which lead to regular ventricular rate.

The PR interval of the surface ECG is measured from the start of atrial depolarization (P wave) to the commensement of ventricular depolarization or QRS complex.

a. what process is occurring in the plant's cells to produce the gas in the bubbles that appear?

b. what gas is the plant producing?

c. what source of energy is the plant using to conduct the process recorded in part a?

Answers

Answer:

a. Photosynthesis

b. Oxygen

c. Light from the lamp

Explanation:

a. The process that is occurring in the plant's cell to produce the gas in the bubble is photosynthesis. The process involves the use of inorganic substances such as carbon dioxide and water in the presence of light to manufacture carbohydrates. Oxygen is evolved in the process. The equation for the process is as below:

[tex]6 CO_2 + 6 H_2O + light --> C_6H_1_2O_6 + 6 O_2[/tex]

b. The gas produced by the plant is oxygen as shown in the equation above.

c. The source of energy the plant is using to conduct the process is the light from the lamp. Light catalyzes the excitation of photosystems, causing the release of electrons that causes the splitting of water.

Carbon dioxide is A a toxic gas produced by landfills. B produced by plants during photosynthesis. C needed by industry to power generators. D a greenhouse gas that traps heat in the atmosphere.

Answers

Answer:

The correct answer is option D, that is, a greenhouse gas that traps heat in the atmosphere.

Explanation:

A natural phenomenon in which the atmospheric gases captivates heat and permits Earth to retain enough solar energy to be livable is termed as the greenhouse effect. The greenhouse gases are the methane, carbon dioxide, nitrous oxide, and other gases, which gathers in the atmosphere and produces a heat-reflective layer that helps in trapping sunlight and keeps the Earth warm.  

Of these greenhouse gases, carbon dioxide is the largest contributor to climate change. It is largely emitted at the time of burning fossil fuels like natural gas, oil, and other carbon-rich sources. Due to this, the level of carbon dioxide increases in the atmosphere resulting in the global phenomenon termed global warming.

Answer:

A Human Cell

Explanation:

A Human Cell can do many things. All your organs, hair, skin, and muscle tissue are all made up of cells. Each human cell from a different part of your body can do and create different things. For example, the cells duplicate (which is reproduction), when it duplicates, it grows. It also uses the oxygen and nutrients for cellular respiration, when it takes in the oxygen and nutrients, it turns it into ATP, which is used to help your cells function. There are many other ways the human cell may relate to the question above. But here are some of the ways a human cell can be all those things.

A toy car is placed at 0 on a number line. It moves 9 cm to the left, then 4 cm to the right, and then 6 cm to the left. What is the total distance the toy car traveled? 1 cm 5 cm 11 cm 19 cm

Answers

Answer:

19 cm

Explanation:

The total distance traveled by the toy cay would be 19 cm.

The total distance traveled should not be mistaken for total displacement. While displacement measures the distance and direction from the starting position of the toy car relative to its final position, the total distance traveled is calculated by adding all the movements of the toy car together. Hence;

Total distance traveled = 9 + 4 + 6 = 19 cm

The total distance the toy car traveled is 19cm

Distance measures how far a body or an object has moved no matter the direction has taken (either positive or negative)

For the toy car that is placed at 0 on a number line, the toy moved the following distance:

9 cm to the left4 cm to the right6 cm to the left.

Total distance = Total distances to the left + total distance to the right

Total distance = 9cm + 6cm + 4cm

Total distance = 19cm

Hence the total distance the toy car traveled is 19cm

What interactions are occurring that allow the water to move against gravity in capillary action? Select three options.

Answers

Answer:

Adhesion and surface tension

Explanation:

Capillary action is the tendency of a liquid to rise or fall in a narrow tube. Two main terms are required to explain capillary action; adhesion and cohesion.

Cohesion is the force of attraction between molecules of the same kind while adhesion is the force of attraction between molecules of different kinds.

Forces of adhesion causes water to move up in a capillary tube. The water is held as it rises by surface tension forces acting on the circumference of the meniscus. The water keeps rising in the tube until the weight of the water drawn up in the tube balances the surface tension acting at the top column of the water.

Which of the following sustainable farming practices allows farmers to rely on their own water supply, rather than bringing in water from different locations? using wells crop rotation drip irrigation using insecticide

Answers

Answer:

drip irrigation

Explanation:

The correct answer would be drip irrigation.

It is a small scale irrigation system that is usually set up to minimize water usage compared to other forms of irrigations. The system consists of different pipes that start from the water source and networks to the stands of plants. Control valves also exist and these ensure that water slowly drips directly to the root of plants. The drip could be either from the above or below the ground surface.

Due to the efficiency associated with dripping water directly to the root of plants which is where it is primarily needed, the drip irrigation system requires minimal water supply and is sustainable.

what would be the affect on pcr reaction, if primers are not added in the reaction?​

Answers

Answer:

In absence of the primer the reaction lacks a primer template junction, and thus a free 3′-hydroxyl group will cause the reaction to fail.

Explanation:

In the PCR reactions primers are used to bind to ssDNA template hybridize itself and define the segment or part of the sample that will be amplified. This hybridize template makes the primer template junction.

If primers not added this junction would not be created then the enzyme DNA polymerase cannot make new DNA due to there is no free 3′-hydroxyl group which is essential to bind with the first deoxynucleotide.

Thus, In absence of the primer the reaction lacks a primer template junction, and thus a free 3′-hydroxyl group will cause the reaction to fail.

On your laboratory test, you are presented with a mollusc that has a closed circulatory system. You know immediately that it must belong to the class ________.

Answers

Answer:

Cephalopoda

Explanation:

Cephalopods are the mollusk that has a closed circulatory system by simple circulation. The heart is located in the pericardic cavity and it is divided into two auricles and one ventricle. From the ventricle, the anterior aorta goes forward the head and the posterior aorta goes forward the visceral mass. The anterior aorta branches into many branchial arteries. All of them get united again in the head, in one cava vein from where the blood returns to the posterior extreme. This vein introduces into the pericardic cavity and brunches into two renal veins near the nephridium. Each branch penetrates into a nephridial sac and passes through the muscular branchial heart before it enters the gills.  Blood passes from the ventricle to the branchia through many vessels. In the branchia, the blood gets oxygenated again and returns to the auricle. The posterior aorta irrigates the gonads and the mantle, and from the posterior extreme of the body, blood goes forward to the anterior body region through two veins that join the renal veins that flow into gill hearts.
