Answer:

From the food we eat

Explanation:

Carbon Dioxide is one of the most important greenhouse gas in the atmosphere. This CO₂ is released from the body of the living organisms during the process of respiration. This Carbon that is present in the CO₂ gas is obtained from the various types of food that the organisms eat. This carbon is taken into the body in the form of essential nutrients such as proteins, carbohydrates. When the oxygen reacts with the food inside the cells, it produces energy and in turn, gives out the CO₂ gas.

Thus, carbon is present in every living organism and plays a crucial role in the carbon cycle.

Ventricular systole begins during the __________ phase of the cardiac cycle. Ventricular systole begins during the __________ ph
Zina [86]

Answer

              Ventricular systole begins during the  <u>isovolumetric contraction </u>phase of the cardiac cycle.

Explanation

1. Ventricular ejection

The forceful expulsion of blood from the ventricles into the aorta and the pulmonary arteries.

2. Isovolumetric contraction

                     The interval between the closing of the AV valves and the opening of the semilunar valves (aortic and pulmonary valves) is known as isovolumetric contraction. it is the beginig of systole. it is the first chamber systolic event. The myocardial muscle fibers have begun to shorten but have not developed enough pressure in the ventricles to overcome the aortic and pulmonary end-diastolic pressures and open the aortic and pulmonary valves. During this period of muscle fiber contraction, the ventricular volumes do not change.

3. Ventricular filling  

                 In this stage AV valve is opened and the blood that has accumulated in atria flow rapidly into ventricles. The ventricular volume increase rapidly. A third heart sound known as S3 is heared during this stage.

4. Isovolumetric relaxation

                  It is the beginning of diastole. The AV valve are closed at beginig. The atrium in diastole has been filling with blood on top of the closed AV valve, causing atrial pressure to rise gradually. The pressure in the ventricles continues to drop. Ventricular volume is at a minimum and is ready to be filled again with blood.

Rachel and her team will conduct canopy fogging to monitor the insect population in an area. Locking at the weather forecast, id
Law Incorporation [45]
Mist nets have been used to capture birds and insects and monitor their populations. Although the number of individuals captured in the nets has been used to estimate population sizes of certain species, this approach can present several problems. On the one hand, to estimate abundances, the use of counting points provides more accurate results, since the data of the capture with nets come from a few points per unit of time. In the case of canopy, the ideal days for this project should be days with the least fog to be able to visualize the species and the impressive vegetation that can be seen from the height, but if what they want is to capture some species for some type of study, they will have to wait for days with more fog.
