The sensory receptors refer to the portions of the nervous system, which sense variations in the external or internal surroundings. The sensory input can be in various forms, comprising taste, pressure, light, sound, pH of blood, or levels of hormones, which are transformed into a signal and are transmitted to the brain or spinal cord.
In the sensory centers of the brain, the barrage of information is integrated and a response is produced. The response, that is, a motor output refers to a signal conducted towards organs via motor neurons, which then transforms the signal into some kind of action, like changes in heart rate, movement, discharge of hormones, and others.
Answer:
Since genes come in more than one version, an organism can have two of the same alleles of a gene, or two different alleles. This is important because alleles can be dominant, recessive, or codominant to each other. I hope this helps
Answer:
- <u>White-bark pine trees:</u>
The specie of plants are found in the most of the national parks of Canada. As they have a high significance in providing more options or ways for the organisms to live. Wildlife is greatly benefited by the presence and increase population of the white-bark pine.
Explanation:
- <u>Effects due to decreased level of White-bark pine trees:</u>
If the population of the white-bark tree is reduced to half, then it will directly effect the level of steep slopes causing destabilization inside it.Along with that, it will also influence and reduce the amount of snow melt by sustaining snow drifts. As decrease in the number of this specie of plant's number will decrease the normal cycle inside the environment, if the cycle is disturbed.Then it will be responsible for the imbalance inside the nature. While it may also cause some of the hazardous events inside the biosphere.
- <u>May cause the decrease in population of the wild life:</u>
There are many species which are benefited by the presence of white bark trees, if the number of white bark tress declines to half then the species present will suffer greatly inside the region. As the support for the species regarding there source of food and shelter will decrease and will bring an imbalance inside the nature.
- <u>Decrease level of vegetation in the region:</u>
Due, to the white bark trees in the area the soil is kept safe from erosion and it increase the supply of nutrients and water towards the plants. As it helps in keeping the soil together which also helps in decreasing the chances of land slides during heavy rainfall in the region.
Now, if the number of the white bark trees declines then it may cause land sliding in the region along with other hazardous events along with it.As the soil capacity to hold itself all together will decrease, causing less water and nutrients transport towards the plants and other beings.
