When observing an ECG, you will see many different deflections from baseline known as waves. These deflections represent various

electrical events taking place in the heart that give rise to the mechanical events that help move blood. In addition to the waves that can be observed, there are flat lines between waves and successive cardiac cycles called segments that also represent particular electrical events that take place in the heart. Finally, certain combinations of waves and segments, known as intervals, also identify important events recorded by the ECG. Match each of the following events with the correct phase of an ECG. Drag the terms on the left to the appropriate blanks on the right to complete the sentences.
A. P wave
B. ST segment
C. QRS complex
D. PR segment
E. T wave
F. QT Interval
1. Atrial depolarization_____.
2. The ventricles are in their depolarized state____.
3. Total time it takes for the ventricular muscle to depolarize and repolarize____.
4. Ventricular depolarization____.
5. Conduction through the atrioventricular (AV) node____.
6. Ventricular repolarization____.
7. Conduction through the atrioventricular (AV) bundle____.

Answer:

1. Ventricular depolarization −−QRS complex

2. Total time it takes for the ventricular muscle to depolarize and repolarize −−QT interval

3. Atrial depolarization −−P wave

4. Conduction through the atrioventricular (AV) node −−PR segment

5. Ventricular repolarization −−T wave

6. The ventricles are in their depolarized state −−ST segment

7. Conduction through the atrioventricular (AV) bundle −−Q wave

Explanation:

ECG or electrocardiogram is the graphical representation of the heart's rhythm and electrical activity measured by electrical signals. The contraction of the heart shows electrical activity.

There are various deflections shows from baseline and known as specific waves and there are also some flat lines between waves called intervals. This atrial depolarization is called P wave and ventricular repolarization called T wave and the time between ventricular muscles depolarization ( QRS complex) and repolarization is QT interval. Conduction through the atrioventricular (AV) bundle is known as Q wave.

Select the correct answer from each drop-down menu. Complete the paragraph based on this food web: Polar bears feed on seals. So
n200080 [17]

Answer:

Polar Bears feed on seals. So, polar bears and seals share a prey predator relationship.  If one species cannot then adapt an appropriate defense, they may go extinct. In this way, the predator prey relationship often forms and "evolutionary arms race", in which eats species rapidly evolves to counter the other.

Explanation:

Complete the paragraph based on this food web: Polar bears feed on seals. So, polar bears and seals share a _prey predator_.Climate change has caused ice caps to melt in colder regions where polar bears live. This change has caused them to hunt less. This situation will lead to_?extinction?_ 1 prey-predator relationship mutual relationship parasitic relationship. 2 less biomass in the quaternary level increased biomass in the quaternary level less biomass in the primary level.

If one species cannot then adapt an appropriate defense, they may go extinct. In this way, the predator prey relationship often forms and "evolutionary arms race", in which eats species rapidly evolves to counter the other.

explain how natural selecin oacting on allele frequencies of a gene that controls body coloraiton can result in populations of 3
Aleksandr [31]

Answer:

Answer below

Explanation:

Well when natural selection occurs, genes that don't benefit the speicies, or more accurately, harm it by ruining camoflague. Natural selection can result in one creature evolving into 3 different species when those creatures get put into different environments that promote genetic mutations that help them survive. After a long while of genetic mutations coming and going to adapt to their environment, those three members of the species are no longer the same species because they've all adapted to different environments.

Compare and Contrast Viruses and bacteria in regard to their structure.<br> Bacteria:<br> Viruses:
yarga [219]

Answer:

On a biological level, the main difference is that bacteria and free-living cells can live inside or outside a body, while viruses are a non-living collection of molocules that need a host to survive.

How many nucleotide bases differ between your sample (labeled as O. Kisutch) and the standard sequence for O. Kisutch? Sample la
OverLord2011 [107]

The right answer is 3 nucleotide bases.

5'-CGGCACCGCCCTAAGTCTCT-3'

5'-AGGCACCGCCCTAAGTCTAC-3'

It would be necessary first to align the two sequences side by side so as to be able to compare them, and they should also be in the same direction.

The nucleotides marked in bold are the nucleotides that differ between standard and O. Kisutch.

These nucleotide changes are necessarily due to substitution mutations that exchanged one nucleotide for another in the same location.

Construct a concept map that shows how a population of bacteria can develop resistance to antibiotics.
Vsevolod [243]

The attached picture shows how bacteria gain antibiotic resistance. Firstly, a few individuals attain a beneficial mutation in their genetic material that accords them the capability to survive in an antibiotic. The individuals are hence able to survive and reproduce more than those individuals without the mutation. There is, therefore, a genetic shift in the population in favor of the resistant genotype. After generations, the whole population becomes antibiotic resistant.
