I believe it's true hope it works
Answer:
The carbon in the air will lessen over time. This is because it is being trapped in the walls of the biodome. This will affect living things negatively as the carbon cycle is a necessary part of nature and throwing off the balance of carbon in the carbon cycle will throw off the balance of the entire ecosystem within the biodome.

Electrical impulses pass from the pacemaker (SA node) through the _______ and the atrioventricular bundle (bundle of His) toward the ventricles.atrium (pl. atria)One of two upper chambers of the heart.capillary<span>Smallest blood vessel. Materials pass to and from the bloodstream through the thin walls. They have walls that are only one endothelial cell in thickness. This delicate, microscopic vessel carries nutrient-rich, oxygenated blood from the arteries and arterioles to the body cells. There, the nutrients are burned in the presence of oxygen (catabolism) to release energy.
At the same time, waste products such as carbon dioxide and water pass out of the cells and into these blood vessels. Waste-filled blood then flows back to the heart in small venues, which combine to form larger vessels called veins.</span>carbon dioxideGas (waste) released by body cells, transported via veins to the heart, and then to the lungs for exhalation.coronary arteriesBlood vessels that branch from the aorta and carry oxygen-rich blood to the heart muscle.deoxygenated bloodBlood that is oxygen-poor.diastole<span>Relaxation phase of the heartbeat.</span>
Gymnosperms are no longer restricted to moist environments, as are ferns and mosses because they have evolved to produce non-flagellated pollens that do not require water or moisture to reach the egg whereas ferns and mosses have flagellated sperm that needs moisture to swim towards the egg.
Another major evolutionary adaption in gymnosperms is the production of seeds instead of spores since seeds contain their own nutrition in the form of endosperm, seeds can travel large distances through wind or animals and can germinate when they find suitable conditions. Seeds can remain dormant for several years whereas spores have a shorter lifespan.

Answer:
by the nitrocellulose membrane filter method. (more info below)
Explanation:
Genetic relationship between mycoplasma as determined by nucleic acid homology. DNA from each of the mycoplasma isolates tested was reacted separately by complementary RNA synthesized with homologous or heterologous DNA as a primer. The amount of DNA-RNA hybrids formed was tested using the method of the nitrocellulose membrane filter.
hope this helped!
