They have limited evidence about the long term consequences, health risks and side effects
There is still limited study on the effects of having low carbohydrates diet. Evidence are not enough to guarantee the safety and efficacy of this type of diet specially in losing weight. The effect of having low carbohydrates in the diet can lead to decrease output of the thyroid, increased input on cortisol, impaired mood and cognitive function, muscle catabolism, suppressed immune function.
The sugar and phosphate portion of the nucleotides are found as segments of the rails on the DNA twisted ladder.
The medulla has the ascending and the descending tract which function to link the brain with the spinal cord.
<h3>What is the role of medulla?</h3>
- Medulla oblongata is the lowermost part of the brain.
- It is located at the place where the brain and the spinal cord connect thus it carries nerve signals between the brain to spinal cord thus help the entire body to communicate.
- It controls biological processes like blood pressure, breathing and heartbeat.
- Ascending tract functions to carry sensory information from the body (e.g.: pain) from the spinal cord to the brain (upwards).
- Descending tract carry motor information (e.g.: instructions to move the arm) from the brain down the spinal cord to the body (downward).
- Damage to medulla can lead to respiratory failure, paralysis, or loss of sensation.

The correct answer is D. Salt water.
Explanation
The hydrosphere is the system that groups all the waters of the earth that include oceans, seas, rivers, lakes, lagoons, frozen waters like ice and snow, among others. The water of the earth can be classified between salt water and freshwater, within the first group we find the oceans and the seas that represent two thirds of the total water of the earth, that is, 93 percent of the total water of the earth, a figure close to 1 370 323 000km³; the rest of the water is fresh and consists of rivers, lakes, lagoons, streams, groundwater, and glaciers. So, the correct answer is D. Salt water
Answer:
A
Explanation:
The thrifty gene hypothesis postulates that due to dietary scarcity during human evolution, people are prone to obesity by storing energy as fat, an ability to take advantage of rare periods of abundance and this is advantageous during times of food availability. individuals with greater adipose reserves would more likely survive famine. This tendency to store fat could lead to obesity.
FTO is an enzyme that is encoded in humans by FTO gene located on chromosome 16. Increase in this enzyme is associated with the regulation of energy intake but not feeding reward. Also, the set point theory indicates that bodies are meant to stay within a narrow weight range but it is susceptible to chnage overtime.
