Svetlanka [38]
<h2>Neural crest </h2>

Explanation:

The neural crest likely forms: neurons and glia of the peripheral nervous system

  • The neural crest are bilaterally paired strips of cells arising in the ectoderm at the margins of the neural tube
  • In the body region, neural crest cells also contribute the peripheral nervous system (both neurons and glia) consisting of sensory ganglia (dorsal root ganglia), sympathetic and parasympathetic ganglia and neural plexuses within specific tissues/organs
  • The nervous system is made up of specialized cells which includes nerve cells (or neurons) and glial cells (or glia)
  • Neurons are the basic functional units of the nervous system, and they generate electrical signals called action potentials, which allow them to quickly transmit information over long distances
  • Glia are also essential to nervous system function, but they work mostly by supporting the neurons

arsen [322]

Answer:

What will most likely happen in these lakes is that there will be a decline of several fish populations. The correct answer is A.

Explanation:

The options attached to the question are given below:

A. The decline of several fish populations

B. An increase in the number of fish.

C. An increase in the number of primary producers.

D. Increased predator- prey relationship.

The fishes, just like any other living organisms has ideal body temperature and pH at which they act best. The ideal pH for fish living in lake water is between 6 and 8. If the pH is reduced below this value then the water will become acidic and this will be toxic for the fish population living in the lakes. Therefore, those fish that can not cope will die and there will be a decrease in the fish populations.

Answer:

1. Supplying

2. Taking

Explanation:

Food chain is a linear relationship between organisms that depicts the flow of energy from one organism to another. In a food chain, organisms are arranged in trophic levels where arrows pointing to the right direction (➡) are used to show that the organim the arrow is pointing to eats the organism behind it.

Hence, according to this question, arrows in a food chain point from the organism SUPPLYING the energy to the organism TAKING the energy.
