No not a good idea because we don’t know what else the “killer mosquitos” will kill. They could kill people if they are allergic to them or they could kill animals. For all we know they might to absolutely nothing about the disease and become invasive. Then we will have way more problems than we started with.

In a simple spinal reflex, the pathway for an impulse is along a sensory neuron directly to a motor neuron through ?A) an effect
Tasya [4]

Answer:

C) an interneuron

Explanation:

A reflex arc is a neural pathway that controls a reflex action. In a simple spinal reflex, the pathway for an impulse is along a sensory neuron directly to a motor neuron through an interneuron because an interneuron enables communications (i.e a pathway for information passage) between a sensory neuron and motor neuron. They play vital roles in reflex actions, neuronal oscillations, neurogenesis in an adult mammalian vertebrate brain.

Which of the following statements is TRUE about fiber? A) Fiber is best obtained through pills and other fiber supplements. B) C
Nostrana [21]

Answer:

C) Increases in daily fiber intake should be gradual.

Explanation:

Fiber is the indigestible part of plants and carbohydrates. Beans, peas and lentils are some sources of fiber.

Fiber is best obtained through dried peas and beans and not from pills and the optimal amount of fiber varies with gender, age and pregnancy so there is no fixed diet for fiber and 25 g  fiber a day is recommended for adult women and 38 g for adult men.

Increases in daily fiber intake should be gradual because a high fiber diet helps to prevent diseases like heart diseases, diabetes, constipation, and colon cancer. It also smoothens the digestive system and lowers the cholrestrol.

Hence, the correct answer is "C) Increases in daily fiber intake should be gradual."
