2. What are the two major subdivisions of the nervous system, and what does each division do?

Answers

Answer:

2 Major Subdivisions:

Central Nervous System

Peripheral Nervous System

Explanation:

The central nervous system (CNS) regulates the majority of bodily and mental activities. It is divided into two parts: the brain and the spinal cord. The brain is the core of our ideas, the translator of our surroundings, and the source of control over physical action.

The PNS is the nerve that links the CNS to the rest of the body. The peripheral nervous system's principal job is to link the brain and spinal cord to the rest of the body and the outside world. The peripheral nervous system sends and receives information to and from the central nervous system. This is done by neurons that convey information from sensory receptors in the eyes, ears, skin, nose, and tongue, as well as stretch receptors and nociceptors in muscles, glands, and other internal organs.

Which group was not present in Linnaeus' system but is present in modern classification systems? A) Species B) Kingdom C) Domain D) Phylum HELP ME

Answers

Answer:

D) Phylum

Explanation:

The group that was not present in the Linnaeus' system but is present in modern classification systems is Domain. The correct option is C.

What is Linnaeus classification system?

The Linnaean classification system is based on a hierarchy of groupings known as taxa. Taxa vary from kingdoms to species.

The kingdom is the most extensive and inclusive grouping. It is made up of organisms that have only a few basic resemblances.

The Linnaean system is significant because it paved the way for the use of binomial nomenclature to distinguish between species.

Scientists could communicate instead of using misleading common names once the system was implemented.

Domain is a group that was not present in Linnaeus' system but is present in modern classification systems.

Thus, the correct option is C.

define the following terms:dispersion and refraction ​

Answers

Explanation:

Dispersion of light is the splitting of white light into its constituent colors due to the refractive index of the surface and the wavelength of the light. If the light entering the prism is not of a single colour then the emergent beam also has different colours arranged in a definite order.

In physics, refraction is the change in direction of a wave passing from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction.

Dispersion is defined to be the spreading of white light into its full spectrum of wavelengths. Refraction is responsible for dispersion in rainbows and many other situations. The angle of refraction depends on the index of refraction, as we saw in The Law of Refraction.

if a plant is not green (does not contain chlorophyll) can it do photosynthesis? why or why not?

Answers

Answer:

No, it cannot carry out photosynthesis because the plant will not be able to absorb light as it does not have chlorophyll.

Explaination:

Chlorophyll in plants is used for absorbing energy from light. And, in photosynthesis, light/sunlight is one of the main factors needed, so as the plant cannot absorb light, photosynthesis can't take place.

what are regenerative cells ???​

Answers

Regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.

Stem cells are specific cells capable of generating new specialized types of cells, thereby allowing the regeneration of damaged tissues.

For example, hematopoietic stem cells can be used to generate new red blood cells whose function is to transport oxygen in the bloodstream.

Regenerative cells can be used in tissue engineering in order to restore the function and structure of damaged organs.

In conclusion, regenerative cells are specific types of cells that can be activated in order to restore organs and tissues back to a pre-existing normal state.
