Answer:
Cushing's syndrome
Explanation:
Prolonged hypersecretion of glucocorticoid hormones by the adrenal gland causes a hormonal imbalance where the person begins to accumulate fat and lose bone and muscle mass.
Remember, one of the most important glucocorticoid hormone is cortisol, also known as the stress hormone, it usually helps us respond to conditions that are difficult for our body and where we need to use our strength and mental dexterity, when this hormone is elevate, we can respond to stress situations more easily. It helps us activate all the metabolism, as a result, we need to use more energy.
If cortisol remains elevated all day, despite not making physical and mental strength, our body will think it needs to eat, so people with this syndrome are always hungry, and accumulate fat. Thus leading to the appearance of the symptoms of the syndrome.
Answer:
4) Some people consider human genetic experiments
unethical.
Explanation:
1) Humans have DNA that is structurally very different from
other mammals.
2) Cloning can only he performed on animals that normally
reproduce asexually.
3) Human genes are made of too many different types of
simple sugars.
4) Some people consider human genetic experiments
unethical.
The statement that provides the most likely reason that a human has not yet been cloned is that some people consider human genetic experiment unethical.
<em>Option 1 is incorrect because human DNA is similar in structure to other living organisms with components such as a phosphate group, a deoxyribose sugar and purine/pyrimidine bases.</em>
<em>Option 2 is incorrect because cloning is not limited to asexually reproducing organisms only. Sheep, for example, produces only sexually and has been successfully been cloned.</em>
<em>Option 3 is incorrect because human genes, just like every other organisms is consist of DNA with deoxyribose pentose sugar being one of the components. The situation of too many different types of simple sugars doe not arise.</em>
The correct option is 4.
Answer:
Glucose
Explanation:
The brain is an energy-hungry organ. Despite comprising only 2 percent of the body’s weight, the brain gobbles up more than 20 percent of daily energy intake. Because the brain demands such high amounts of energy, the foods we consume greatly affect brain function, including everything from learning and memory to emotions.
Just like other cells in the body, brain cells use a form of sugar called glucose to fuel cellular activities. This energy comes from the foods we consume daily and is regularly delivered to brain cells (called neurons) through the blood.
Studies suggest the quality of the foods consumed over a lifetime affects the structure and function of the brain. For instance, the consumption of omega-3 fatty acids found in fish provides structural material to maintain neurons. Studies also suggest omega-3 fatty acids are essential for the transmission of information between brain cells. In contrast, foods that are rich in sugars and saturated fats have been found to promote oxidative stress, which leads to damage to cell membranes.
The food you eat also affects molecules in the brain that support cognition. Some foods, such as those with turmeric, support cognition by helping to maintain molecular events related to energy metabolism.
Recent studies suggest lifestyle choices that affect the metabolism of nerve cells, such as diet and exercise, may in some cases provide a non-invasive and effective strategy to counteract neurological and cognitive disorders.
Glucose particles are ingested from gastrointestinal cells into the circulatory system. The circulation system then, at that point, conveys the glucose particles all through the body. Glucose enters every cell of the body and is involved by the cells mitochondrion as fuel.
