In different tissues ie skin tissue, recovery is possible due to the cell's ability to divide constantly. new cells simply replace the dead ones and heal the injury. neurons divide very rarely because they are highly specialized cells so they are not able to replace the dead. the injury is unable to recover.
What is the central nervous system?The central nervous system is the system of cells which are specialised in transmitting the signals in the body which plays an important role in the control and coordination of the body.
The specialised cells which transmit the signals are known as the neurons which are surrounded by the cells which protect the neurons and support them in performing their functions called the neuroglia.
The tissue of the central nervous tissues which control the whole body is the spinal cord and the brain.

Answers
Developing 150 breeds of dogs from ancestral wolves is not an example of natural selection.
The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others. People that possess advantageous qualities, or adapted traits, are more likely to live and procreate. The adaptable qualities are subsequently passed on to the next generation by these people. These beneficial characteristics spread across the population over time. Favorable features are passed down across generations as a result of natural selection. Natural selection may result in speciation, the process by which one species gives rise to another that is utterly separate.
Hence, survival of the fittest species take among population.

Which of the following models shows the flow of energy in a woodland ecosystem? Select the two correct answers.sun → tree → caterpillar → birdsun → caterpillar → bird → hawksun → hawk → bird → caterpillarsun →grass → mouse→ owlsun → tree → grass → mouse
Answers
In ecosystems, there is a constant flux of energy. This energy enters the ecosystem through the sum of chemical compounds and is distributed to all living organisms of the ecosystem.
When the energy enters the ecosystem, it is used by autotrophs organisms to produce organic compounds.
There are two types of "producers" that use the energy and inorganic molecules to create "food"
-Photoautotrophs: these organisms use sunlight to synthesize organic molecules. Among these organisms, you can find plants, algae, and some species of bacteria.
-Chemoautotrophs: these organisms use the energy from chemical compounds to produce food. Among these organisms, you will find bacteria.
The next step in the flux of energy of the ecosystem you will find the "consumers", that is, organisms that depend on other living organisms for food.
These organisms are called heterotrophs, they can be animals or fungi, and can be classified depending on what they eat as:
-Herbivores: they consume plants or algae.
-Carnivores: they consume other animals.
-Omnivores: they consume both plants and animals.
The last step in the flux of energy in the ecosystem is the decomposers. These organisms break down the remains and waste of other organisms and release inorganic molecules and the energy stored within the remains back into the environment, where autotrophs will be able to use them to synthesize more food.
The decomposers are also classified according to the type of organic matter they break down:
-Scavengers: consume softs tissues of dead animals.
-Detritivores: consume detritus (dead leaves, animal feces, and other organic debris)
-Saprotrophs: consume the remaining organic matter left by the other decomposers.
So, the flux of energy can be summarized as follows:
Check the given models to determine which ones represent the energy flux of the woodland:
1) sun → tree → caterpillar → bird
The energy source is the sun, this energy is used by the tree (autotroph), then is consumed by the caterpillar (heterotroph, herbivore) and finally the caterpillar is consumed by the bird (heterotroph insectivore)
This model represents the energy flux.
2) sun → caterpillar → bird → hawk
The source of energy is the sun following this model the energy of the sum is used by the caterpillar. This is wrong since caterpillars are heterotrophs and not autotrophs, so they cannot use the energy of the sum to synthesize food.
This model does not represent the energy flux of the ecosystem.
3) sun → hawk → bird → caterpillar
Same as the previous model, this model shows that the energy of the sun is used by a hawk, but hawks are heterotrophs, they cannot use the energy to produce their food, there is a link missing which is the one represented by the autotrophs.
This model does not represent the energy flux of the ecosystem.
4) sun →grass → mouse→ owl
The energy source is the sun, this energy is used by an autotroph organism, the grass. The grass is consumed by the mouse ( heterotroph, herbivore) and finally, the mouse is consumed by an owl (heterotroph, carnivore)
This model represents the energy flux.
5)sun → tree → grass → mouse
The energy source is the sun, which is used by a tree (autotroph), the next link of the chain is another autotroph organism, the grass, this organism cannot use the energy stored within the tree, so this model does not apply.
This model does not represent the energy flux of the ecosystem.
The models that represent the flux of energy in woodland are numbers 1 and 4.

C.
Lighter colored mice had more dominant genes in their new habitat.
D.
Lighter colored mice were more likely to avoid predators and to reproduce.
Answers
Lighter colored mice were more likely to avoid predators and to reproduce. Therefore, option (D) is correct.
The lighter brown coloration of the deer mice in the Sand Hills of Nebraska is likely an adaptation that provides them with a survival advantage in their specific habitat. The light, sandy soil in the area may offer better camouflage for lighter colored mice, making them less visible to predators and increasing their chances of survival.
As a result, these mice would have a higher likelihood of successfully reproducing and passing on their lighter coloration traits to future generations.

Two locations have different water vapor Contant in the atmosphere which of this is likely to be recorded
Answers
Answer:
The water vapor content in the atmosphere is typically recorded using a measurement called relative humidity, which represents the amount of water vapor present in the air relative to the maximum amount the air could hold at a given temperature. Therefore, if two locations have different water vapor content in the atmosphere, it is likely that they would have different relative humidity readings.
For example, if one location has a higher water vapor content in the air, it would have a higher relative humidity measurement than a location with a lower water vapor content. Conversely, if one location has a lower water vapor content in the air, it would have a lower relative humidity measurement than a location with a higher water vapor content.
It is important to note that other factors can also influence relative humidity measurements, such as temperature and atmospheric pressure, so a direct comparison of relative humidity readings between two locations should take these factors into account.

A lesser quantity, these hormones can play an essential function in elevating the speed of germination, and they instigate cell elongation so that the plants grow taller. The following are the essential uses of gibberellins:
1. Promote flowering
2. End seed dormancy
3. Increase the size of the fruit.
For the seeds to germinate, there is a need for seed dormancy to end, and this can be done with the use of gibberellins. The hormone also promotes the process of flowering, which helps in the production of more fascinating and larger specimens of flowers.
The flowering process also influences the rate of the growth of fruits. Gibberellins are also used in the generation of seedless fruits. The spraying of the hormone helps to enhance the size of the fruit.

Explanation:
1) Hydrogen atom & glucose molecule --- atomic.
The atomic size level, which interacts with atoms as well as small molecules, is much lower than the ultramicroscopic range.
2) Herpesvirus, DNA --- ultramicroscopic.
Ultramicroscopic particles are very tiny structures that cannot be seen using a conventional optical microscope, necessitating the use of an electron microscope. Viruses and DNA falls into this group since they are much smaller than tiny species like bacteria.
3) Protozoan, Rickettsia - microscopic.
Microscopic species are much smaller than macroscopic organisms because they cannot be observed by the naked human eye and must be viewed through a microscope.
