The heart’s electrical system is responsible for making and conducting signals that trigger the heart to beat. These signals cause the heart’s muscle to contract. With each contraction, blood is pumped throughout the body. This happens 24/7 without us having to monitor it all the time so that our heart does not stop.
The first part, transcription, begins in the nucleus, when the DNA code is transferred to mRNA. The second part, translation, takes place at the ribosomes, where both mRNA and tRNA work to assemble proteins. A biological catalyst. Anabolic enzymes build up, Catabolic enzymes break down.
Plantae is the kingdom that only contains producers. They produce food for themselves and others, rather than taking food.
The competition is the condition, in which someone proves the superiority over others. In nature, the competition is one of the greatest factors responsible for the evolution especially natural selection.
The resources in the nature are present in a limited amount. The resources such as water, air, land, habitat, and the food are shared by many organisms. As these resources are limited, there is a fight between different species for the same resource. In this condition, the organism, who is able to prove its superiority can survive better.
Hence, the main reason of competition is limited availability of the resources.
