Answer:

Convergent evolution

Explanation:

The convergent evolution is a very interesting evolutionary process that is also very helpful when ti comes to explaining how the evolution actually works. This type of evolution appears when two or more different species, be it plants or animals, live in places that are isolated from one another, but have the same or very similar living conditions. The species then evolve in a very similar manner despite them not being closely related at all, bu the response from them is the same in order to survive in the environments that provide the same conditions. If the conditions are very harsh, hot, and dry, thus a desert, then the two plants will develop the same or very similar features. They will have very hard leaves that stop the loss of water. The amount of leaves will be very low. The root systems will be disproportionately large. They will both have the ability to extract humidity from the air. The chances are also very high that they will both have thorns for protection, as well as certain amount of poison in them for the same purpose.

In ________ conditioning, an established conditioned stimulus is paired with a new neutral stimulus.
irina [24]

An established conditioned stimulus is paired with a new neutral stimulus in: higher-order conditioning.

Classical conditioning refer to a learning process that involves the repeated pairing of two (2) stimuli:

  • Conditioned stimulus.
  • Unconditioned stimulus.

Basically, classical conditioning is a learning procedure which helps psychologists in understanding when a neutral stimulus is paired with a conditioned response or a neutral stimulus and an unconditional stimulus.

Similarly, a higher-order conditioning involves pairing an established conditioned stimulus with a new neutral (the second-order) stimulus, in order to make the new stimulus elicit (bring forth) the conditioned response, without presenting the initial conditioned stimulus.

ElenaW [278]

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.
