I believe the answer to your question would be A. TAC and a simple way to understand sequence codes is A goes with T, U goes with A, And G goes with C.
The correct answer is that mammals use a closed, double loop , four chambered heart as a circulatory system of the body.
The circulatory system of mammals is closed system that consists of four chambers, two articles and two ventricles. The deoxygenated blood comes into the heart from one loop and the oxygenated blood from other loop from the heart is circulated to the whole body. This is called as double circulation.
Answer:
A. more oxygen to enter the atmosphere
Explanation:
Photosynthesis is a metabolic process unique to the cells of autotrophic organisms, due to the possession of the CHLOROPHYLL pigments used in trapping light energy from the sun. Photosynthesis is the process of combining carbondioxide (CO2) and water (H2O) using energy of sunlight to produce glucose and release oxygen gas.
Based on the understanding of the photosynthetic process which is similar in all photosynthetic organisms including photosynthetic prokaryotes e.g. cyanobacteria, the presence of the photosynthetic PROKARYOTE will allow more oxygen in the atmosphere.
Note that, oxygen is released during photosynthesis.
Answer: It is supported by hypotheses, repeated tests and law from one or more fields of science.
Explanation:
In the context of science, a theory is a well-established explanation for scientific data. Theories typically cannot be proven, but they can become established if they are tested by several different scientific investigators.
