Mr. Helms was admitted to the hospital with chest pains and shortness of breath. His wife was panicked since her 72-year-old hus
Lynna [10]

Answer:

Explanation:

1- the purpose of blood flow-circulatory system- is to convey  Oxygenated blood, oxygen bonded with haemoglobin in the RBC with Nutrients - and distributed these through the arteries  and capillaries  away from the heart,  to reach the cells and tissues, and transported the wastes of theses cells and tissues , with C02 through the veins back to the heart and the kidney.

2. During diastole,deoxygented blood from the inferior and superior vena cavae entering the R.atrium, passes through the tricuspid valve into the Right Ventricle. Simultaneously, oxygenated blood returning through the pulmonary veins enters the left Atrium,emptied  through the bicuspid valve into the Left.Ventricle.

During systole, the two ventricles contracts. The Right ventricle contracts, the pressure of the blood forces  the tricuspid valve to close,and therefore de -oxygenated blood pushes the pulmonary  valves to open and blood passes through the pulmonary artery to reach the lungs where exchanges of oxygen with carbon dioxide occurs.The blood is now oxygenated and returns to the left atrium via pulmonary veins.

Simultaneously, the left ventricle contracts,the oxygenated blood it contains forced the bicuspid valve to close so that blood is  forced through the aortic valve  to empty into the aorta into  the systemic circulation,branches of the carotid artery supplies the heart from the aorta.

The Whole cycle continues.

Plants that we recognize today spend the majority of their life in the A. haploid phase. B. gametophyte phase. C. seed phase. D.
sdas [7]

Answer:

The correct answer is D: diploid phase

Explanation:

The essence of plant life is their characteristic property of alternation of generations. Each plant undergoes alternation of generations and produces haploid and diploid generations.

This property allows the plant to reproduce both sexually and asexually. Primitive plant species used to reproduce through spores and spent the majority of their life as haploid cells. These cells were called as spores and required only matter and energy to reproduce.

Modern plant species reproduce by using gametes and spent the majority of their life in diploid phase called diploid sporophytes.
