Negative feedback systems are responses in your body that happen in order to maintain homeostasis and balance within a system. One example of negative feedback system is thermoregulation. If we did`nt have that, the temperature of our organisms would change drastically and it could cause bad consequences for our health and body functioning. The correct answer is letter A: Negative feedback systems allow humans to regulate ans stabilize their systems.
Answer:
Starch is an example of a simple carbohydrate.
Explanation:
Carbohydrates are made up of three components: fiber, starch, and sugar. Fiber and starch are complex carbs, while sugar is a simple carb. Depending on how much of each of these is found in a food determines its nutrient quality.
Answer:
The Mid-Atlantic Ridge (MAR) is a mid-ocean ridge, a divergent or constructive plate boundary located along the floor of the Atlantic Ocean, and part of the longest mountain range in the world. In the North Atlantic, it separates the North American from the Eurasian Plate and the African Plate, north and south of the Azores Triple Junction respectively. In the South Atlantic, it separates the African and South American plates. The ridge extends from a junction with the Gakkel Ridge (Mid-Arctic Ridge) northeast of Greenland southward to the Bouvet Triple Junction in the South Atlantic. Although the Mid-Atlantic Ridge is mostly an underwater feature, portions of it have enough elevation to extend above sea level, for example in Iceland. The ridge has an average spreading rate of about 2.5 centimetres (1 in) per year.[1]

Answer:
A promoter refers to a DNA sequence, that is, situated upstream of a gene and signals the start of transcription.
A repressor refers to a transcription factor that prevents transcription by combining with the operator site.
An insulator refers to an element that obstructs the signals between the promoters and enhancer.
A regulatory gene refers to a gene, which monitors the expression of one or more genes by preventing or encouraging transcription.
An inducer refers to a molecule that stimulates the synthesis of mRNA by disabling the protein, which inhibits the transcription.
An operator refers to a short sequence of DNA situated close to the promoter region, and is recognized by a repressor protein.
The correct answer is: B) 6 CO2 + 6 H2O ? C6H12O6 + 6 O2
Photosynthesis is a process of converting light energy to chemical energy in the form of sugars (carbohydrates). It is performed by plants, some algae and bacteria.
In the reaction of photosynthesis, sun energy combined with carbon dioxide (CO2) and water (H2O), to form glucose (C6H12O6) and oxygen (O2). Photosynthesis consists of two stages: the light-dependent reactions (in thylakoid membrane) where ATP is formed and the Calvin cycle (in stroma) where ATP is used.
