Hormones Facts And Questions! Trivia Quiz

The correct answer is the endocrine system. Hormones are chemical substances produced by glands in the body, and these glands are part of the endocrine system. The endocrine system is responsible for producing and regulating hormones that control various bodily functions and processes, such as growth, metabolism, reproduction, and mood. Unlike the other systems listed (immune, circulatory, and lymphatic), the endocrine system specifically deals with hormone production and regulation.

Geotropism is the response of plants to gravity, where shoots grow upwards and roots grow downwards. Auxins are plant hormones that regulate growth and development. In the case of geotropism, auxins work differently in shoots and roots. In shoots, auxins inhibit growth on the lower side, causing the shoot to bend upwards. In roots, auxins promote growth on the lower side, causing the root to bend downwards. Therefore, the statement that auxins work differently depending on whether it is a shoot or a root is true.

Hormones are transported to and affect specific cells in the body, known as target cells. These cells have specific receptors that can bind to the hormones, allowing them to respond to the hormonal signals and carry out the desired effects. The term "target cells" accurately describes the relationship between hormones and the cells they interact with, as these cells are the intended targets for the hormonal actions.

Hormones are carried by plasma in the blood because plasma is the liquid component of blood that transports various substances, including hormones, throughout the body. Plasma acts as a medium for hormones to travel from their site of production to their target organs or tissues. It also helps maintain the balance of hormones in the bloodstream by regulating their concentration. Red blood cells, on the other hand, primarily carry oxygen and carbon dioxide and do not play a significant role in transporting hormones.

The liver is responsible for metabolizing and breaking down various substances in the body, including hormones. Once hormones have completed their function, the liver helps in breaking them down and removing them from the bloodstream. This process ensures that hormone levels are regulated and maintained within the body.

In a dangerous, fight or flight situation, the body releases adrenaline. This hormone is produced by the adrenal glands and helps prepare the body for a response to a perceived threat. Adrenaline increases heart rate, blood pressure, and blood flow to the muscles, providing a burst of energy and heightened awareness. It also dilates the airways, allowing for increased oxygen intake. Overall, adrenaline helps to mobilize the body for action and enables a quick response to potential danger.

Auxins are a plant hormone that regulates and affects both shoot and root growth. They promote cell elongation in shoots, resulting in upward growth, and inhibit cell elongation in roots, leading to downward growth. Auxins also play a role in the development of lateral roots and adventitious roots. Overall, auxins are crucial for coordinating and regulating the growth and development of different parts of the plant.

Adrenaline is a hormone released by the adrenal glands in response to stress or danger. It has several effects on the body. Increased strength is one of the effects of adrenaline as it prepares the body for physical exertion. Increased heart rate is another effect, which helps to pump more oxygenated blood to the muscles. Adrenaline also increases senses and reactions, making individuals more alert and focused. It stimulates the liver to produce more glucose, providing energy for the body. Lastly, adrenaline diverts blood flow to vital organs, ensuring they receive enough oxygen and nutrients during stressful situations.

During phototropism, auxins move away from the light, which causes the plant to grow towards the light. This is because auxins are plant hormones that promote cell elongation and growth. When light is detected by the plant, auxins accumulate on the shaded side of the stem, causing the cells on that side to elongate more rapidly than the cells on the illuminated side. As a result, the stem bends towards the light. Therefore, the correct answer is "Away, towards".

These are examples of hormones. Hormones are chemical messengers produced by the endocrine glands and released into the bloodstream. They regulate various bodily functions and processes. Adrenaline, noradrenaline, growth hormone, and insulin are examples of hormones produced by the adrenal glands, pituitary gland, and pancreas respectively. Testosterone and estrogen are sex hormones produced by the testes and ovaries respectively.

Auxins are plant hormones that play a crucial role in the growth and development of plants. In terms of geotropism, auxins are always pushed downwards by gravity. This means that they accumulate in higher concentrations in the lower parts of the plant, such as the roots. As a result, auxins make shoots grow faster downwards, exhibiting negative geotropism, while they inhibit root growth, resulting in slower growth and positive geotropism.
