2 Detect the endocrine glands on models and charts and their histological properties in the microscope.

3. Analyze the effects of aging, imbalances, and diseases of the endocrine system.

Answers

1.The hormones of the hypothalamus and the anterior and posterior pituitary gland are antidiuretic hormone and oxytocin and ADH.

What hormones are produced by the hypothalamus and their functions?

The hormones produced by the hypothalamus and secreted by the neurohypophysis are antidiuretic hormone and oxytocin. Antidiuretic hormone promotes an increase in urine concentration, as it ensures greater reabsorption of water by the kidneys.

2. The endocrine glands on models  are :

hypothalamus.Hypophysis. Thyroid gland.Parathyroid glands.Islet cells of the pancreas.Adrenal glands. Testicles in men and ovaries in women.

What are the general characteristics of the endocrine glands?

The main feature of endocrine glands is the absence of excretory ducts. The service product produced by endocrine cells is transported to the extra diffusion space, reaching the interior of blood vessels.

3. When an imbalance of the endocrine system occurs, it results in Hormonal disorders can be caused by various factors such as diabetes, psychological changes, stress, eating disorders, regular use of medication and cancer.

Carbon dioxide (CO2) is the most significant of the greenhouse gases. Volcanic outgassing, organic matter burning and natural decay, and aerobic (oxygen-using) organisms' respiration are all natural sources of atmospheric CO2. On average, these sources are counterbalanced by a collection of physical, chemical, or biological processes known as "sinks," which remove CO2 from the atmosphere. Terrestrial flora, which absorbs CO2 during the photosynthesis process, is a significant natural sink.

What is the normal level of CO2 in the atmosphere?

CO2 levels in the air and probable health issues are as follows: The average outdoor air level is 400 parts per million. 400–1,000 ppm: typical concentration found in inhabited spaces with adequate ventilation. Drowsiness and poor air quality are linked to levels of 1,0002,000 ppm.

Human activities, on the other hand, increase atmospheric CO2 levels primarily through the combustion of fossil fuels—primarily oil and coal, and secondarily natural gas—for transportation, heating, and electrical power generation, as well as the creation of cement. Forest fires and land clearing are two further examples of anthropogenic origins.

Anthropogenic emissions currently account for around 7 gigatons (7 billion tons) of carbon released into the atmosphere each year. Anthropogenic CO2 emissions account for about 3% of total CO2 emissions from natural sources, and this magnified carbon burden from human activities far surpasses natural sinks' balancing capacity (by as much as 2–3 gigatons per year).

Effects:

Sea levels are rising, and the oceans are warming. Droughts that last longer and are more intense endanger crops, wildlife, and freshwater supplies. The richness of life on our world is threatened by climate change, from polar bears in the Arctic to sea turtles off the coast of Africa.

Ways to reduce global warming?

Improvements to energy efficiency and vehicle fuel economy, increases in wind and solar power, biofuels from organic waste, setting a price on carbon, and protecting forests are all potent ways to reduce the amount of carbon dioxide and other gases trapping heat on the planet.

3. Provide examples from your model of conservation of matter through Earth's spheres.
4. Identify the limitations of your carbon model in accounting for all of Earth's carbon.

Answers

3. Matter is lost on earth but energy is transformed from one form to another. The ultimate source of energy is the sun and then its is transformed from one form to another. The matter is not converted from one form to another form, it gets destroyed as the plant and dies. So, we can say the energy is conserved on earth but the matter gets destroyed.

4. The carbon model is the flow and the movement of the carbon and its compound in the atmosphere. Climate change is the limitation of the carbon model.

What is climate change?

A climate change is a variation in the weather and the climate pattern due to a change in temperature and other atmospheric factors. It will lead to a transformation in the flow of carbon in the environment.

Increased carbon in surroundings increases temperature and results in a change in seasons and humidity levels, leading to changes in the rainfall.

Therefore, climate change is the limitation of the carbon model.

Some weight-loss diets are believed to speed up the body's metabolism to help a person lose weight quickly. Other diets rely on very low-calorie intake for rapid weight loss. Is it important, when changing one's diet, to know how the cells in your body will react to the introduction of new substances or removal of other substances?

Answers

Answer:

It is super important

Explanation:

It is critically important that one must know how and what your body needs before introducing new things or removing old things. For eg. people tend to go on keto diets (high fats). But, one must know that our brain neurons require very high energy and need constant sugar. Therefore, if you intake very low sugar in keto diet, you might actually harm yourself more than benefit.
