Explain the interaction between the central nervous system and the peripheral nervous system.

Answers

The central nervous system (CNS) is composed of the brain and the spinal cord. The peripheral nervous system (PNS) is composed of all of the peripheral nervesthat connect all of the parts of the body with the CNS. List three general functions of the nervous system.

The crucial regulatory, controlling and communicating system of the body is called the nervous system. It has an important role in acquiring and giving responses to a stimulant.

How do Central nervous system and PNS interact?

The central nervous system comprises of the brain and spinal cord while the PNS have nerves spread throughout the body parts.

The PNS connects the central to the body tissues, organs and skin structures with the help of nerves. The central nervous system receives information from the PNS via the nerves and helps in transmitting the response to the action received.

Therefore, PNS and central nervous system are interrelated to each other for functioning.

Can a dead cell carry out diffusion and active transport?

Answers

I would say the answer to that question would be no, as it has to be alive. Hope this helps!

No, a dead cell cannot carry out active transport as it requires ATP, which dead cells do not produce. Diffusion may continue passively for some time, but active processes cease with cell death.

Can a dead cell carry out diffusion and active transport? No, a dead cell cannot carry out active transport because active transport requires energy, which is usually obtained from ATP. Living cells use metabolic energy to maintain concentration gradients of ions and other substances across their membranes. This energy is particularly crucial for active transport processes such as the Na+-K+ ATPase pumps in red blood cells, which maintain the imbalance of sodium and potassium ions across the cell membrane. Once a cell dies, it ceases to produce ATP, thus halting active transport mechanisms. While diffusion is a passive process that might continue for a time after a cell perishes due to existing concentration gradients, without ATP, the active transport processes cannot occur in a dead cell.

Over the last several decades, the scientific community has gathered a large amount of information regarding genetics and genetic variation. What are two main sources that lead to increased genetic variation?(((((Both answers must be selected.))))) A) Selective breeding, B) Gamete mutations, C) Recombination, D) Genetic drift

Answers

Answer:

B) Gamete mutations, C) Recombination

Explanation:

Any random changes in the DNA of gametes are called as gamete mutations. These mutations are transmitted to the next generation via gametes and thereby the genetic variations are increased.

Recombination is the production of new gene combinations. Crossing over during meiosis I of gamete formation add new gene combinations to gametes. Random fertilization of these gametes add even more genetic variations to the progeny.

b. Only a small fraction of energy radiating from Earth is from the atmosphere.
c. The Earth’s surface is responsible for a small fraction of heat radiation to space.
d. Earth’s surface absorbs little of the energy that strikes as solar radiation.

Answers

Answer: c. The Earth’s surface is responsible for a small fraction of heat radiation to space.

Explanation:

In later ages the large amount of sun's energy is reflected back by the terrestrial surface back to the space. But now due to the abundance of large concentration of greenhouse gases in the atmosphere is responsible for the absorption of thermal energy from sunlight by these gases causing the atmosphere to be hot. This is the reason of global warming. Now only small fraction of heat is radiated back to the space.

What conducts electric current in solutions?

elements

electrolytes

atoms

molecules

Answers

Answer:

Electrolytes

Explanation:

An electrolyte is a substance that conducts electricity when dissolved in a polar solution e.g water. They are particles that carry a positive or negative electric charge called Cations and Anions respectively.

Electrolyte can also be referred to as a substance that dissociates into ions in solution and acquires the capacity to conduct electric currents. It becomes an ionic conductor when fused or dissolved in a suitable solvent.

Electrolytes include Sodium, pottasium, calcium, bicarbonate and magnesium amongst other body minerals. These minerals carry a small electric charge in fluid environment.

Electrolytes conducts electric current in solutions. Therefore, the correct option is option B.

In order for our bodies to function properly, electrolytes are necessary, and realising this can do a lot for our general health. They are minerals that, when dissolved in water, take on an electrical charge and are necessary for a number of physiological activities. Sodium is one of the most well-known electrolytes. It is essential for maintaining the equilibrium of bodily fluids, neuron activity, and muscular contraction. Sodium influences how much water the body retains, which influences blood pressure. However, consuming too much sodium can result in health problems like high blood pressure and fluid retention.

Therefore, the correct option is option B.

D) anaerobic respiration.

Answers

B. Photosynthesis because the organisms on the bottom of the pyramid are plants meaning they get their food from the sun.

-Hope I helped!

Answer: The correct answer is -

B) photosynthesis

Explanation:

Photosynthesis can be described as process of creating food (in the form of glucose) in green plants, algae, and some protist (that are called producers). It uses inorganic molecules that are carbon dioxide and water in the presence of energy from sunlight to synthesise glucose and release oxygen as waste in surroundings.

It takes place in the specialized membrane bound organelles, called chloroplast.

Producers occupy the base of any food chain, which can be represented by energy pyramid, thus they produce enough chemical energy to support the entire ecosystem through photosynthesis.
