1. If we compare the lengths, the good answer would be the neurons.
The body of the neuron measures from 5 to 120 μm. The size of a neuron (or rather an axon) varies from a fraction of a micron to two meters (the equivalent from the brain to the toe).
2. The particularity of neurons is that it does not divide, but survive for a very long time.
Neurons do not usually die before the death of the entire organism. However, many types of trauma and pathology can shorten the duration of their existence. Neurons that disappear and are rarely replaced (or not) because there are few stem cells that can differentiate into neurons in the mature nervous system. Like most cells, neurons can die in two different ways: necrosis or apoptosis.
Oxygen and Carbon dioxide
<span>The task is to complete the sentence: As each order of consumers eat other organisms, energy that transfers (...). We know that only around 10% of energy gets transferred between the different levels - the rest gets lost (for example because not everything gets eaten or because it gets lost as heat). So the energy "decreases" - that's how you can complete the sentence!</span><span />
Instinct, that would be what is inherited.
Explanation:
Almost all the oxygen you breathe comes from green plants. They produce oxygen during a process called photosynthesis. During photosynthesis green plants manufacture the sugar molecules fructose and glucose. Green plants use energy from sunlight to build sugar molecules from carbon dioxide and water
