Answer:
A central nervous system is consist of brain and spinal cord. The brain is made of the cerebrum, cerebellum, and brain stem.
The parts of the central nervous system involved in given behaviors are as follows:
- <u>Listening to music:</u> The cerebrum in the brain is responsible for the behaviour of listening music as it functions for auditory stimuli (temporal lobe).
- <u>Realization of being thirsty:</u> limbic system in brain is responsible for the regulation of thirst.
- <u>Feel that soda is no longer cold: </u>Hypothalamus in brain controls the sense of temperature felt by the body.
- <u>Decide to invite a friend over: </u>The cerebrum functions for thinking and decision making.
This is a symbiotic relationship between the Boxer crab and sea anemone.
<h3><u>Explanation</u>:</h3>
The symbiosis is a type of relationship between two species which has benifit for both the participating organisms.
Here in case of boxer crab, the crab gets the help from the sea anemone in the form of protection. The sea anemone chases the predators and thereby saves the organism from being hunted.
On the other hand, the sea anemone gets food from the crab's prey which he hunts.
So there's a benifit for both.
Diploid cells contain 2 sets of the same DNA where as haploid contains one set.....so our normal cells in our body (somatic cells) are diploid however our sex cells(gametic cells) which are the egg of a woman and sperm from a guy are only haploid which means they have only 1 copy of DNA......this is because they fuse with one another and add their DNA together to make a diploid cell
In plants the reproductive structure that produces pollen and seeds is the xylem is the answer
Like all life on earth, plants need water to survive and grow. Indeed, like humans, water is the primary element that makes up the structure of plants. Human bodies are comprised of around 70 percent water, but in plants this proportion can be as much as 95 percent. Water is also essential to the way a plant receives nutrients and provides energy for itself. Thus, water is arguably the most essential substance required by plants. That is why many elements of permaculture design – from using swales and contouring to slow runoff from the land and allowing it to sink into the soil to mulching to prevent evaporation of moisture from the soil surface – emphasis the preservation of water so that it can be provided to plants.
hope this helped :)
