why are different leads are used to measure the ECG

Answers

Different leads are used to measure the ECG simply because each lead is recording the electrical activity of the heart from a different direction

Each individual lead's ECG recording is slightly different in shape. This is because when the electrical activity within the heart travels towards a lead you get a positive deflection.

Electrocardiogram

An electrocardiogram (ECG) is a simple test that can be used to check the heart's rhythm and electrical activity. Sensors attached to the skin are used to detect the electrical signals produced by your heart each time it beats

tissue respiration, location in the cell and sequence of reaction​

Answers

Answer:

The Location of Cellular Respiration

Cellular respiration takes place in both the cytosol and mitochondria of cells. Glycolysis takes place in the cytosol, whereas pyruvate oxidation, the Krebs cycle, and oxidative phosphorylation occur in the mitochondrion.

Tissue respiration occurs internally where the oxygen carried by the blood and RBCs is exchanged with the carbon dioxide produced by the cells of various tissues. ( This answers the location of where tissue respiration occurs

Sequence of tissue respiration

The stages of tissue respiration include:glycolysis - pyruvate oxidation - citric acid or Krebs cycle - oxidative phosphorylation.

Cell tissue respiration

It is the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water

Cellular tissue respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate, and then release waste products.

What are temperate grasslands?

Temperate grasslands are biomes characterized by vast expanses of open grasslands with few trees or shrubs. These ecosystems experience a wide range of temperature fluctuations between seasons, with hot summers and cold winters. As a result, animals that live in temperate grasslands have evolved adaptations that enable them to survive in this challenging environment. One of the most common adaptations of grassland animals is the ability to dig burrows. Burrows provide shelter and protection from predators, as well as a stable microclimate for animals to live in.

Hence, structures to dig burrows are a common adaptation for animals that live in temperate grasslands, as is present in the first option.

How does the air pressure at sea level compare with air pressure at higher elevations such as
Mt. Everest. In your explanation include information about the number of air molecules in a
parcel of air at that altitude and the affect of gravity on pressure at both altitudes.

Answers

Answer:

Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.In addition, gravity is weaker at the equator due to centrifugal forces produced by the planet's rotation. It's also weaker at higher altitudes, further from Earth's centre, such as at the summit of Mount Everest

Labor unions arose in the nineteenth century as increasing numbers of Americans took jobs in factories, mines, and mills in the growing industrial economy.

The Knights of Labor, founded in 1869, was the first major labor organization in the United States. The Knights organized unskilled and skilled workers, campaigned for an eight hour workday, and aspired to form a cooperative society in which laborers owned the industries in which they worked.

The Knights’ membership collapsed following the 1886 Haymarket Square riot in Chicago. By 1886 the American Federation of Labor (AFL), an alliance of skilled workers’ trade unions, was growing.

Which type of effort to preserve species do you
think is most worthwhile?

Answers

One of the most effective and worthwhile methods of species preservation is the preservation and protection of wildlife habitats.

What is a habitat?In the most simple of terms, a habitat is a section of terrain in which certain organisms live. Habitats can range from deserts to rainforests and everything in between.

How protecting them can be important.The protection of habitats is of utmost importance. The leading cause of species extinction is habitat loss due to human activities such as city expansions or the collection of raw materials for industrial use. Protecting species habitats will allow the species in question to not only survive but also thrive and reproduce, thus leading to a safe population number and avoiding extinction.

Therefore, we can confirm that one of the most effective and worthwhile methods of species preservation is the preservation and protection of wildlife habitats to allow the species that live in them to thrive.

Graded potentials are changes in membrane potential that vary in size, as opposed to being all-or-none.

Explanation:

btw, where are the options?

The statement which correctly describes a graded potential is: amplitude of various sizes.

Graded potential refers to a temporary change in electric or membrane potential of a stimulus with respect to both its size and distance.

Amplitude can be defined as the maximum displacement of a wave when measured from its equilibrium position.

Thus, amplitude is measured vertically from an equilibrium position.

Generally, a graded potential is directly proportional in amplitude to the size of the stimulus that is send as an input due to the following:

The pedigree on the right shows the inheritance pattern for an X-linked recessive disorder.
The mother of the individuals circled in pink is not shown on the pedigree. Based on the phenotypes of these individuals and their father, what are the possible genotypes of their mother? Check all of the boxes that apply.
- XAXA
- XaXa
- XAXa

Answers

The mother's genotype can be either [tex]X^AX^A[/tex] or [tex]X^AX^a[/tex].

For X-linked recessive traits, males (XY) can either be affected or free from the disorder, they cannot be carriers. Females (XX), on the other hand, can be affected, unaffected, or be carriers.

The circled male child is free from the disorder ([tex]X^AY[/tex]) while the females are carriers ([tex]X^AX^a[/tex]).

The male inherited the healthy allele, [tex]X^A[/tex], from the mother.

The female children inherit the affected allele from their father (who is affected for the disorder) and the other healthy allele from their mother.

This means that the mother cannot be affected for the disease. As it is, the pedigree points that all the children got their healthy alleles from their mother. This does not mean the mother has two healthy alleles though.

Thus, the possible genotype of the mother are [tex]X^AX^A[/tex] and [tex]X^AX^a[/tex].

(Suited for Spacewalks - Adapted from NASA) Following Gemini, the Apollo program added a new dimension in spacesuit design because actual spacewalks, on the surface of the Moon, were now to occur for the first time. As with Mercury and Gemini space garments, Apollo suits had to serve as a backup pressure system to the space capsule. Besides allowing flexibility in the shoulder and arm areas, they also had to permit movements of the legs and waist. Astronauts needed to be able to bend and stoop to pick up samples on the Moon. Suits had to function both in microgravity and in the one-sixth gravity of the Moon's surface. Furthermore, when walking on the Moon, Apollo astronauts needed the flexibility to roam freely without dragging a cumbersome combination oxygen line and tether. A self-contained portable life-support system was needed. The Apollo spacesuit began with a garment that used water as a coolant. The garment, similar to long johns but laced with a network of thin walled plastic tubing, circulated cooling water around the astronaut to prevent overheating. A multi-layered pressure garment was worn on top of the cooling suit. The innermost layer of this garment was a comfort layer of lightweight nylon with fabric ventilation ducts. On top of this was a layer of neoprene-coated nylon surrounded by a nylon restraint layer. This layer contained the pressure inside the suit. Improved mobility was achieved by bellow-like joints of formed rubber with built-in restraint cables at the waist, elbows, shoulders, wrist, knees, and ankles. On top of the pressure layer were five layers of aluminized Mylar for heat protection, mixed with four spacing layers of non-woven Dacron. Above these were two layers of material for additional thermal protection and a non-flammable layer of Teflon coated in a fibrous cloth. The outermost layer of the suit was white Teflon cloth. The last two layers were flame resistant. In total, the suit layers provided pressure, served as a protection against heat and cold, and protected the wearer against micrometeoroid impacts and the wear and tear of walking on the Moon. Capping off the suit was a communications headset and a clear plastic pressure helmet. Slipped over the top of the helmet was an assembly consisting of sun-filtering visors and adjustable blinders for sunlight protection. The final items of the Apollo spacesuit were lunar protective boots, a portable life-support system, and custom-sized gloves with molded silicone-rubber fingertips that provided some degree of fingertip sensitivity in handling equipment. The life-support system, a backpack unit, provided oxygen for breathing and pressurization, water for cooling, and radio communications for lunar surface excursions lasting up to eight hours. Furthermore, back inside the lunar lander the life-support system could be recharged with more oxygen and battery power for additional Moonwalks. During the Apollo program, 12 astronauts spent a total of 161 hours of extravehicular activities on the Moon's surface. Additional extravehicular activities were spent in microgravity while the astronauts were in transit from the Moon to Earth. During a total of four hours, one astronaut, the command module pilot, left the capsule to retrieve photographic film. There was no need for the portable life-support system away from the Moon, as those astronauts were connected to the spacecraft by umbilical tether lines supplying them with oxygen.Drag each label to the correct location on the image.
