Answer:

estrogen

Explanation:

Estrogen, also known as estrogen, is a female sex hormone produced by the ovaries and released in the first phase of the menstrual cycle. It is the estrogen that confers all the female characteristics of women, such as breast size, texture and skin brightness, and is responsible for controlling ovulation and preparation of the uterus for reproduction.

PolarNik [594]

Answer:

The correct option is 2 Nephrogenic diabetes insipidus.

Explanation:

Nephrogenic diabetes insipidus (NDI) occurs when the renal tubule response to vasopressin (ADH) is weakened, resulting in the excretion of large volumes of dilute urine.

As the renal tubules do not respond to vasopressin (antidiuretic hormone) and are unable to reabsorb filtered water back into the body, the kidneys create a high volume of dilute urine in nephrogenic diabetes insipidus.

Nephrogenic diabetes insipidus (NDI) can be inherited or develop as a result of disorders that impede the ability of the kidneys to concentrate.

Therefore, the correct option is 2 Nephrogenic diabetes insipidus.

That is, the most likely cause of his polyuria is nephrogenic diabetes insipidus.

Most of the energy that your brain uses comes from
evablogger [386]

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.
