Answer:

This is because all nerves from various parts of the body meet at the spinal cord before reaching the brain.

Spinal cord is said to be centre of reflect action because they are:

1. Involuntary actions that involve reflex arc

2. In most of the vertebrates information does not travel directly to the brain through the reflex arc.

3. Basically it travels through the synapse and reaches the spinal cord

which acts as the centre for these actions and send an appropriate response for the stimulus.

Spinal cord is a long tube like structure enclosed by a vertebral column. It carries signal from the brain and then transfer themto different body parts.

Injury to the occiput, atlas and axis can cause bleeding and blood accumulation around the atlanto-axial joint, leading to chemical irritation of the C2 nerve root.

Fibrous tissue may develop around the nerve root during the chronic period, causing more irritability and pain. Occipital, atlantoaxial, and axis injuries most frequently impact the C2 nerve root since it is the lowest in the cervical spine.

Both the motor and sensory regulation of the muscles of the neck and scalp are carried out by this nerve root. The patient may have discomfort and/or muscular weakness in the neck and scalp if the C2 nerve root is damaged.

Additionally, nausea, vertigo, and trouble regulating the neck muscles might result from inflammation of the C2 nerve root. Rest, physical therapy, and medication are all used as treatments for C2 nerve root irritation or injury. For long-term relief, surgery may be required in severe situations.

Coral reefs provide a wide range of ecosystem services to other ecosystems. For instance, coral reefs protect shorelines from storm surges and waves.

The coral reefs also help in preventing coastal erosion. Additionally, coral reefs serve as a habitat and nursery ground for numerous species of fish and other marine organisms. These organisms, in turn, provide food for larger predators such as sharks and whales, which migrate through different ecosystems.

Moreover, coral reefs are also a significant source of revenue for countries that depend on tourism, as many people visit the reefs to snorkel, dive, or simply enjoy their beauty. Coral reefs also have a significant role in nutrient cycling and carbon fixation, helping to regulate the global climate. Overall, the importance of coral reefs cannot be overstated, as they provide essential services to many other ecosystems in the ocean and beyond.

The type of reproduction that produces offspring which is identical to the parent is called: asexual reproduction.

Offspring that arises from asexual reproduction produces are genetically identical to a single parent. The offspring produced are genetically as well as physically identical to each other. Asexual reproduction can be observed in multicellular and unicellular organisms both.

Asexual reproduction is the simplest and most primitive method of reproduction that involves single parent and produces a clone, an organism that is genetically identical to the parent.

In asexual reproduction, haploid gametes are not involved. A parent passes all its genetic material to next generation.

The introduction of a new pesticide into the habitat of a beetle population has had significant effects on the environment and the beetles themselves.

The introduction of a new pesticide to the habitat of a beetle population can have various effects on the environment and the beetles. Firstly, the pesticide might directly impact the beetles by causing mortality or affecting their reproductive capabilities.

This can lead to a decline in the beetle population size, as individuals are unable to survive or reproduce successfully. Secondly, the pesticide may also disrupt the ecological balance within the habitat. It can affect other organisms in the ecosystem, such as the beetle's natural predators or prey, leading to cascading effects throughout the food web.

Additionally, the pesticide may persist in the environment, causing long-term contamination and posing risks to other non-target organisms. Overall, the introduction of the pesticide has altered the dynamics of the beetle population and the ecosystem it inhabits, potentially leading to ecological imbalances and negative consequences for biodiversity.

The type of ecological service that is maintaining habitat for wildlife including insects, birds, and big game is "supporting."

Ecological services are the benefits that humans gain from natural ecosystems. There are four types of ecological services: provisioning, regulating, supporting, and cultural. They are referred to as ecological services because they are essential to human well-being and the survival of the ecosystem. Maintaining habitat is an example of an ecological service that is supporting. This is because maintaining habitat helps the survival of many different species by giving them a place to live, shelter, and food. Rangelands play a significant role in supporting this ecological service as they provide a natural home for a wide range of species including insects, birds, and big game. Rangelands are a crucial source of food and habitat for wildlife. They help maintain the ecological balance of the ecosystem by providing the necessary resources for the different species of animals that inhabit the ecosystem. They are important for the survival of many different species of animals, including insects, birds, and big game.

Hybrid breakdown is defined as the reduced fitness observed in the offspring of the hybrids. the reduced fitness is however not observed in the hybrid themselves.

Fitness in the evolutionary terms is the reproductive success of an individual or a whole population. If two individuals are able to breed and produce fertile offspring, then they are considered to be fit and can believed to adapt better in their surroundings.

Hybrids are the offspring produced by the mating of two organisms belonging to different breeds, variety species or even genera. The example of hybrid is a mule obtained by the breeding of a horse and a donkey.
