Answer:
Positive feedback mechanism:
This mechanism has positive correlation between the products and the process. The positive feedback mechanism result in the growth of a product. This mechanism is less common in organism and perform under specific conditions. Example: Process of blood clotting involves positive feedback mechanism.
Negative feed back mechanism:
This mechanism has negative correlation between the products and the process. Negative feedback mechanism result in the inhibition of the product. This mechanism is more common in organism and maintains homeostasis in the body.Example: Regulation of blood pressure involves negative feedback mechanism.
Answer:
Doppler Radar
Explanation:
Doppler radars are considered one of the best tools used for the detection of rainfall in a particular area. These radars work by way of sending beams out in a circular pattern all round the radar. Once a beam hits a hailstone or a raindrop, part of the beam is reflected back towards the radar.
Answer: Eat more nutrient-dense foods
Reduce intake of saturated fats
Eat more fruits and vegetables
Explanation:
Eat more nutrient-dense foods: The food rich in fibers, proteins, and other nutrient-based food will provide strength to the body and will also support the weight loss by stopping the tendency of frequent eating by increasing the mass of food that one eats.
Reduce intake of saturated fats: Saturated fat tends to increase the low-density lipoproteins or bad cholesterol in the body. This LDL will increase the cholesterol level in the body and will cause an increase in weight gain.
Eat more fruits and vegetables: Fruits and vegetables are a good source of fibers, which will keep the stomach full for a long time. Thus will reduce the dependency on high fat-containing food.
<span>In order for individuals best suited for growth and reproduction in a particular environment to contribute disproportionately to the next generation natural selection must take place. Natural selection is one of the basic mechanism of evolution. This mechanism leads</span> to adaptations and adaptations contribute to survival and reproduction.
