When the concentration o molecules inside a cell is different form the concentration of molecules outside a cell, we can either call it hypertonic or a hypotonic solution, and the difference between the two concentrations is called a concentration gradient.
Hypertonic - name given to a solution that has a bigger concentration than the concentration in a cell.
Hypotonic - name give nto a solution that has a smaller concentration than the concentration in a cell.

The mammalian tail and the human coccyx, the leaves of pitcher plants and cacti, are homologous organs while, the flippers of penguins and dolphins, as well as the shells of turtles and crabs are analogous structures.
<h3>What are homologous organs?</h3>
Homologous organs are those that are similar in structure but operate differently. They resulted from divergent evolution.
Divergent evolution occurs when species are closely connected to the same ancestors but develop similar structures that perform different tasks in different environments.
Analogous Organs are organs from various creatures that, despite their appearance, perform the same function.
In the given case, the mammalian tail and coccyx, as well as the leaves of pitcher plants and cacti, are homologous organs, whereas penguin and dolphin flippers, as well as turtle and crab shells, are analogous structures.
Thus, these are the different instances of homologous and analogous organs.

Neurons have three parts that carry out the information and
integrations and these three are dendrites, axons, and axon terminals. The key
function of the neuron is to send, receive, and infer information from the
body. The special neurons - axon sends info away and the dendrites receive.
Cellular respiration is the process by which glucose is transformed into ATP. -- It uses oxygen and gives off carbon dioxide and takes place in the mitochondria of the cells. -- It helps maintain homeostasis by transforming energy that can be used to do cellularwork.
