The answer is vitamin D. This is actually a group of vitamins of similar molecular structure responsible for facilitating increased absorption of calcium, magnesium and phosphate from the gut. The most important of the vitamin D compounds are vitamin D3 and D2. While vitamin D can be obtained from your diet and supplements, the major source of vitamin D is from a chemical reaction dependent on skin exposure to the sun.
Answer:
Explanation:
1.) All organisms differ in traits such as size and behavior.
2.) No two individuals are exactly alike.
3.) There was a gradual change in each species.
4.) Fossils were different from the living animals. However, these fossils had many similarities to modern forms of life.
5.) Species on the Galapagos Islands resembled species on the mainland but they were different in certain characteristics.
6.) Some organisms became isolated on many islands.
Diffuse modulatory synapses or neuromodulation function different than simple point-to point synapses.
1. Number of postsynaptic neurons
In neuromodulation neuron uses one or more neurotransmitter to regulate several neurons. In Synaptic point-to-point transmission only one particular neuron receives signal from the presynaptic neuron.
2. Neurotransmitter sin neuromodulation (neuromodulators) are not reabsorbed broken down by the pre-synaptic neuron like those in classic synapse. Neuromodulators stay in cerebrospinal fluid.
3. Receptors are also different: the receptors for the neuromodulators are typically G-protein coupled receptors while in classical chemical neurotransmission, they are ligand-gated ion channels.
4. Neuromodulation is a slow process, while classic synaptic transmission occurs fast.
Answer:
The correct answer in A) All electrical activity of the brain has ceased for a specified period of time
ATP is produced via prototrophy, fermentation, and aerobic respiration, and it is used for mechanical, transport, and chemical work.
<h3>Which of the following types of work is powered by the energy produced when ATP is hydrolyzed to ADP and Pi?</h3>
A nucleotide, a sugar with five carbons, and three phosphate groups make up ATP. Phosphoanhydride bonds, which link the phosphates, contain a considerable amount of energy. Cellular work is accomplished using the energy generated by the hydrolysis of ATP into ADP + Pi.
<h3>What are the two mechanisms that, when combined, form oxidative phosphorylation and are connected throughout the ETC?</h3>
The electron transport chain and chemiosmosis are two parts of oxidative phosphorylation that are interdependent. When electrons are transferred from one molecule to another in the electron transport chain, energy is released.
