ECG wave that causes ventricles to contract

Biology
1 answer:
GarryVolchara [31]3 years ago
6 0

Answer:

S-T segment of ECG shows ventricles contraction.

Explanation:

The ECG is used to measure the electrical signals that controls the contraction and relaxation of heart, most commonly known as heart rhythm. S-T segments are the region after the QRS wave in ECG which is further followed by T waves. The S-T segment is generally shown as a straight line as no electrical signal pass through it and this is the time when ventricles contraction in the heart takes place.

How did you test your hypothesis? which variables did you control in your experiment and which variable did you change in order
elixir [45]

Hypothesis is a proposed explanation which is made on the basis of given experimental data taken as starting point for further investigation. All hypothesis test are conducted in a same manner fiollowing the four main steps:

1. State the hypothesis

2. Formulate an analysis plan

3. Analyzing the data obtained

4. Final step is to analyze the results

There are three types of variables taken in an experiment:

1. Independent variable: light, temperature, humidity

2. Dependent Variable: these depends upon the other variable. changes in the independent variable may cause the dependent variable to change, for example, growth of plant is a dependent variable which depends upon the amount of light(independent variable), the plant receives

3. Controlled Variable: these variable can be controlled and prevented from being change like ty[pe of plant, type of soil

Which part of photosynthesis is represented by the diagram to the right
Yanka [14]

Answer:

<em>Light-dependent reactions</em>

<em></em>

Explanation:

Photosynthesis occurs in two stages: light-dependent reactions and light independent-reactions. This last stage is often called Calvin cycle.

The diagram shows reactions occurred in the thylakoid membranes which are located inside the chloroplasts. Therefore, we can identify that these reactions are the light-dependent reactions. During this part of photosynthesis, the energy from the sunlight is absorbed by a pigment called chlorophyl (Chl). Then, it is sequentially coverted into chemical energy stored in the form of molecules: NADPH (nitotinamide adenine dinucleotide phosphate) and ATP (adenosine triphosphate).
