Answer:
When comparing the thickness of the heart's ventricles, the left one is thicker than the right one, because it must generate more pressure to pump blood throughout the body.
Explanation:
In the human heart, the right ventricle is in charge of pumping the blood to the lungs —initiating the minor circuit of the circulation— while the left ventricle is in charge of pumping the blood to the whole body.
To fulfill its function, each ventricle has a specific thickness in its walls, the left one being thicker than the right one.
The right ventricle is a chamber that handles more volume than pressure, and its walls are thinner because it does not require much pressure to pump the blood to the lungs. The left ventricle has a thicker muscular wall because it is a chamber that must generate a high pumping pressure, so its contraction force must be greater.The structure of the myocardium in the heart is what allows each chamber to fulfill its function adequately.

Reaction: C6H120, + 6
A -> 6
B + 6 H2O + energy
What molecules does letter B represent in the reaction above?
02
O CO2
ОАТР
O H2O
The reaction of cellular respiration involves the use of the glucose molecule in presence of oxygen to produce energy and carbon dioxide. Thus, option B is correct, as molecule B is carbon dioxide.
What is cellular respiration?Cellular respiration is a chemical method that involves the inhaled oxygen and use of the food molecules to release energy along with the water and carbon dioxide molecules.
Cellular respiration can be depicted by the reaction:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + energy
Therefore, molecule B is carbon dioxide.

What do you mean by interphase?Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

Trees, such as those in the deciduous forest, are very important to the environment. If the number of trees on earth continues to decrease significantly, what might be the result? (Site 1)
Answer:
more carbon dioxide would build up without the tress to recycle it and many animals would lose their habitats
Answer:
Animals will begin to migrate towards residential areas if the number of trees on the planet continues to decline, as their natural habitat would be destroyed. There are numerous plant species that can be used as a source of medicine for disease prevention and treatment. Trees provide a significant amount of oxygen to the environment. Some deciduous forest trees grow near rivers, preventing soil erosion by attaching dirt to the plant's roots. Cottonwood, mountain ash, and fruit trees are commercially important trees. If there is a considerable reduction in the quantity of trees, all of the above benefits of trees will be lost.

How does greenhouse effect, affects biodiversity and gradual extinction
Answer:
Greenhouse gases let the sun’s light shine onto the Earth’s surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth’s climate comfortable. Without it, surface temperatures would be cooler by about 33 degrees Celsius (60 degrees Fahrenheit), and many life forms would freeze.
