1. Respiratory brings oxygen and nutrients to the cells, while the circulatory
moves gases in and out of the blood. These work together because they have to exchange carbon dioxide and oxygen with each other.
2. The main parts and functions of the respiratory system are, the nose, pharynx, larynx, trachea, bronchi, and the lungs. As I said in the first answer, The respiratory brings oxygen and nutrients to the cells.
3. The main parts and functions of the circulatory system is the heart, lungs, arteries, veins, coronary, and portal vessels. The circulatory system moves gases in and out of the blood.
4. There are two main parts in your lungs, the pharynx, and the larynx. So, when you swallow food, the epiglottes blocks the entrance to these two main parts. Simply..if you could breath while doing this..I think you could die.
5. They are connected to capillaries that distribute blood to and from all the cells.
Answer: Genetics and Pressures
Explanation:
For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.
Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.
Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.
<h2>Neural pathways of taste</h2>
Explanation:
- The tongue contains little knocks called papillae, inside or approach which taste buds are arranged. In the tongue's taste buds, the taste receptors get tangible information by means of two significant systems – depolarization and synapse discharge. Admission of salty nourishments drives more sodium particles to enter the receptor, causing the said systems. The equivalent is valid with admission of sharp nourishments (hydrogen particles) and sweet nourishments (sugar atoms), the two of which result to the end of K+ channels upon their entrance.
- From the axons of the taste receptors, the tangible data is moved to the three taste pathways by means of the parts of cranial nerves VII, IX and X. The chorda tympani of CN VII (facial nerve) conveys the taste tangible contribution from the tongue's foremost 66%. At that point, the remainder of the taste sensations from the throat, sense of taste and back tongue are transmitted by the parts of CN IX (glossopharyngeal nerve) and CN X (vagus nerve).
- From these cranial nerves, taste tangible information goes through the nerve fiber neurotransmitters to the lone tract, the ventral posteromedial thalamic cores , and the thalamus. In these three areas, there are grouped neurons which react to a similar taste (sweet, sharp, salty or bitter).The thalamus transfers the data to the essential gustatory cortex situated in the somatosensory cortex. The essential gustatory cortext is the place the impression of a specific taste is handled.
Sound waves are slower than electromagnetic waves. Sound waves behave only as a wave, whereby electromagnetic waves act both as a wave and particle, and travel at the speed of light 3.0 x 10^8 m/s d (which is very fast!!!)
Answer:
it is your lungs
Explanation:
epithelial cells line the insides of the lungs, the gastrointestinal tract, the reproductive and urinary tracts, and make up the exocrine and endocrine glands.
