Answer:
External respiration: CO2 diffuses into the blood
Explanation:
External respiration is also called the pulmonary gas exchange. It refers to the diffusion of O2 from the air in the alveoli of the lungs to blood in pulmonary capillaries and diffusion of CO2 in the opposite direction from the capillary blood into the alveolar air. External respiration in the lungs is responsible for oxygenation of deoxygenated blood coming from the right side of the heart. The oxygenated blood is then returned to the left side of the heart.
Answer:
Heat Energy
Explanation:
When energy is transformed from one form to another, or moved from one place to another, or from one system to another there is energy loss. This means that when energy is converted to a different form, some of the input energy is turned into a highly disordered form of energy, like heat.
Hope this helped! :^)
<span>In order to know whether the plants are members of one population with great diversity or actually members of the same species we can attempt to find out whether they reproduce or not. That's one of the main aspects of two organisms of the same species - fertility.
We could start by setting up some kind of artificial environment where both plants would pollenise at the same time, or we could also collect the pollens from both plants and store it to use them in a different time of the year than that of their production.
After having the pollens available from both plants we could fertilise a group of both plants with each other's pollens (the actual object of study), and also fertilise a group of both plants with their own pollens (so we can have a control for the quality of the pollens and the plants - in this group it is expected to have offspring, if there isn't we cannot take into account any other results).
After the fertilisation, we should now count the offspring. If there is offspring resulting from the crossed plants, they are probably of the same species. We could also compare these plants with the offspring of the normal crossing to check whether there were major differences (such as health issues, or offspring number) that would lead to conclude that still there wasn't compatibility.
By creating a hybrid between this two groups, even if they are from the same species, we may have to take also into account that they may have different required conditions than their parent plants.
</span>The study should be repeated a few times or the number of plants involved should be large enough to be statistically relevant.
