The correct answer is (4) Autotrophic organism.
Green plants make their own food by the process of photosynthesis using sunlight. Most of the autotrophs use carbon dioxide, sunlight and carbon dioxide to produce glucose that is used by the plants to obtain energy. Most of the oxygen comes from these organisms and decrease in the number of green plants can lead to several problems due to decrease in the amount of oxygen. Example: green plants, algae, and even some bacteria. This food and oxygen is produced by the action of autotrophic organisms
Answer:
The main function of the circulatory (or cardiovascular) system is to deliver oxygen to the body tissues, whilst simultaneously removing carbon dioxide produced by metabolism.
Any condition in an experiment that can be changed is a control variable!!
You control it!!
Answer:
The sequence data that would support this hypothesis would involve there being relatively more differences found between the three mitochondrial genes' sequences of the La Plata River dolphin and the sequences of the Chinese River dolphin.
There should also be fewer differences between the three mitochondrial genes' sequences of the La Plata River dolphin and the sequences of the Amazon River Dolphin.
Explanation:
This is because fewer differences between the mitochondrial gene sequences of two species indicate closer relatedness and more differences indicate lower relatedness.
