Explanation:
The stratum corneum, which is the outermost epidermal layer, consists of dead cells
The principal function of thyroxine is to stimulate the consumption of oxygen and thus the metabolism of all cells and tissues.
Thyroxine is termed T4. It travels through the blood to the target cells and becomes converted to triiodothyronine or T3.
T3 is the active form of thyroxine. T3 enters the target cell's nucleus binding to genes responsible or involved in the metabolism of sugar in the body. T3 stimulates these genes and in so doing metabolism (conversion of oxygen and calories to energy) is carried out by the cell, which also results in generation of body heat.
One word that describes all the processes that happen in a living thing is life cycle
The movement of nutrients into the vascular stele requires energy, unlike the movement of water that does not require energy. This energy is provided by the phloem. Sugars are produced in the leafs, as part of the photosynthesis process, so whenever a new root is growing, or a fruit needs to grow, the phloem gets in action. With the help of the water the sugars get in the phloem, which can most simply be seen as an elevator inside the plant, that is moving nutrients up and down, on the places in which they are most needed.
<span><span>Dendrites
</span><span>Dendrites are projections of a neuron that receive signals from other neurons through chemical signals and electric impulses (electrochemical signals). Dendrites are covered with synapses (gland cells over which nerve impulses pass) which help them integrate information from many other neurons. The dendrites usually receive the signal transfer through chemical signals and it then travels to the cell body (soma) of the neuron from which the dendrites project. Most neurons have several dendrites, which may branch many times and frequently extend over a large area.
