</span>Mutations are changes in the DNA. A single mutation can have a large effect, but in many cases, evolutionary change is based on the accumulation of many mutations. Gene<span> flow is any movement of </span>genes<span> from one population to another and is an important source of</span>genetic variation<span>.</span>

Answer:
It would be Active transport.∞←
Explanation:
The wall of the left ventricle is thicker than that of the right - True
The left ventricle pumps more blood than the right - False
<u>Explanation:</u>
Heart has 4 number of chambers. One among these chambers is the left ventricle. Among the four cambers of the heart, the thick one is the left ventricle. It appears below the left atrium. The left ventricle is present in the bottom left part of the heart. When the contraction of heart occurs the blood from the valve called mitral enters the left atrium from the left atrium.
The left ventricle transports the oxygenated blood to the human body. The left ventricle needs along these things for pumping the blood. The right ventricle can function by itself and is more powerful than left ventricle. The right ventricle is responsible in pumping blood to the lungs on its own.
Answer:
When plants and animals die, organic molecules also undergoes decomposition and this causes the incorporated phosphates to go back to the soil or bodies of water.
Explanation:
Phosphates are naturally related to <u>"phosphorus."</u> <em>They play a vital role in the life of animals and plants. </em>Phosphorus can be commonly be found on the earth's land and water (although the land has a smaller amount of it). <u>Plants naturally absorb phosphate from where they're growing. Animals take up phosphates by eating plants.</u> The phosphate that plants get from the soil are considered inorganic. They only become organic when it is incorporated into the plants DNA (since this is an organic molecule).
So, this means that if there's a sufficient amount of phosphate, there will be more plants on earth as it is also important in the process of acquiring nutrients.
When animals and plants die, all of the organic molecules such as phosphate also breaks down and thus, it falls back to the soil or bodies of water. Then, they are ready to enter another Phosphorus cycle.
