A hypothesis is when you make an educated guess before you complete the experiment. It is basically an inference on what might happen next. So a conclusion made based on facts.
If there are respiring organisms within that sample of air, the partial pressure of oxygen decreases because the organisms utilize it for respiration activities.
Answer:
Chromosome pairs with its corresponding homologous chromosome to form a tetrad.
Answer:
The moon is about one-fourth the size of Earth.
Explanation:
- The Moon has a diameter of 3,476 km and is one-fourth of the size of the earth. Moon is about 27% lesser than the size of the earth.
- Earth's moon is the fifth largest moon in the solar system having a radius of 1,737 km.
- The surface area covered by the moon is about 37.9 mn km square. It is even smaller than the continent of Asia. The moon's mass is about 1.2% of the mass of the earth.
The percentage of the stroke volume is ejected during the first quarter of systole will be approximately 60% to 65%
<u>Explanation:</u>
The time interval between the atria contraction and the relaxation of ventricles are called as a Cardiac cycle. Systole denotes the heart contraction during the blood pumping. Diastole refers to the heart relaxation when the blood is filled in the heart chambers. The total blood is not fully pumped by the ventricles.
Instead they will pump only a proportion of blood in each of the cardiac cycle. The ejection fraction refers to the proportion of the intraventricular volume that is received as a output in circulation process. A human with normal heart functioning can have approximately 60-65%. This is known to be stroke volume. The blood volume that is ejected is strove volume.
