<h2>Human Reproductive System</h2>
Explanation:
- The most <em>Flowering plants</em> have a distinctive element is their <em>reproductive organs, ordinarily called flowers</em>
- Sexual propagation in flowering plants includes the develop of <em>female and male gametes</em>, the exchange of the <em>male gametes to the female ovules in a process called pollination</em>
- The part of reproductive plant organ,the flower contain pistil <em>(female flower part) and stamen (male flower part),or plus accessory part such as petals,sepals and nectar gland</em>
- The stamen is the male reproductive organ. It consists of a <em>pollen sac (anther) and a long supporting filament</em>
Answer:
C. a pre-synaptic neuron involved in egg-laying
Explanation:
Serotonin (5-HT) is a neurotransmitter, i.e., a molecule that binds to specific receptors and thus transmits signals from one pre-synaptic neuron to another target cell. In humans, serotonin is involved in many physiological functions including sleep, mood, emotions, appetite, digestion, etc. Moreover, <em>Caenorhabditis elegans</em> is a model organism widely used in neuroscience research in order to understand neuromodulation at the level of individual neurons. In <em>C. elegans,</em> serotonin modifies behavior by regulating neuronal excitability and synaptic efficiency. Moreover, also in <em>C. elegans,</em> it has been shown that serotonin induces egg-laying and also provides a feedback regulatory mechanism by inhibiting the activity of the pre-synaptic neurons that release it. In consequence, in this case, it is expected that serotonin rescues the loss of function of serotonin receptors required for egg-laying by providing a regulatory feedback loop that contributes to serotonin adaptation.
Rotates?
Ex: Foucault's pendulum is an easy experiment demonstrating the Earth's rotation. When Léon Foucault first performed the experiment in 1851, the concept that the Earth revolves was nothing new or radical; the pendulum's accomplishment was to provide a proof that did not require minute observations of the stars or other objects far removed from Earth. Foucault's pendulum is a highly localized, easily prepared experiment whose result is clear, powerful, and accessible even to the non-scientist. In short, the pendulum provides everything a science teacher could ask for in an instructional experiment.
Glycogen reserves can release glucose for cellular respiration. glycogen reserves are typically found in the muscles and liver.
- The liver and muscles contain the body's "quick" source of energy, known as glycogen stores.
- They go through further metabolism after being converted to glucose.
- After that, glucose can be further digested to release energy both aerobically and anaerobically.
<h3>Glycogen reserves: what are they?</h3>
- When the body doesn't need to consume the glucose for energy, the liver and muscles store it.
- This kind of stored glucose, which is made up of many connected glucose molecules, is known as glycogen.
<h3>How long are glycogen reserves good for?</h3>
- Utilizing the form, you can learn more about nutrition and glycogen.
- But it's helpful to know that once glycogen stores are exhausted, it will take at least 48 hours to fully refill them.
- This necessitates rest throughout the recovery period and a high-carbohydrate diet (60–70% of the energy must come from carbohydrates).
