Insects (Insecta) are the most diverse of all animal groups. There are more species of insects that there are species of all other animals combined. Their numbers are nothing less than remarkable, both in terms of how many individual insects, as well as many species of insects that are. In fact, there are many insects that is not very known how to count them all, the best thing we can do is to make calculations.
Approximate scientists who can be as many as 30 million species of insects alive today. To date, they have identified over 1 million. At any time, the number of live insects on our planet is amazingly, some scientists estimate that for every human being alive today, there are 200 million insects.
The success of insects as a group is also reflected in the diversity of habitats in which they live. Insects are more numerous in the land such as deserts, forests and grassland environments. They are also numerous fresh water such as ponds, lakes, streams and wetlands habitats. Insects are relatively scarce in habitats marine, but are more common in the waters brackish, like marshes and mangrove

Last Friday after dealing with the stressors of daily life, Jane was likely to have <u>increased level of cortisol</u> in her blood stream.
Explanation:
Daily life activities, responsibilities, duties, events all leads to a lot of stress among individuals. This stress affects our body, thoughts, mind, feelings and behavior.
Cortisol is a stress hormone secreted by the adrenal glands by the triggering of adenocorticotropic hormone of the pituitary gland.
Stressors due to daily life activities and other health problems leads to cortisol awakening response and increases the level of cortisol in the blood stream in order to cope up with the increased stress.
Increased cortisol levels causes a number of health issues like anxiety, depression, headache, digestive issues, cardiac problems, sleep disturbance, cognitive impairment etc
<span>Myelination enhances the speed of action potential propagation.
The difference between myelinated and unmyelinated axons are in the propagation of action potential. In unmyelinated axons, the action potential travels continuously through the axons. On the other hand, among the myelinated nerve fibres, transmembrane currents can only occur at the nodes of Ranvier where the axonal membrane is exposed, so the excitation of the axonal membrane jumps from node to node. This propagation is called saltatory conduction and this movement of depolarization wave is much faster than in unmyelinated fibres.</span>
