Answer:
nucleolus
Explanation:
The nucleus contains the cell 's DNA and directs the synthesis of ribosomes and proteins. Found within the nucleoplasm, the nucleolus is a condensed region of chromatin where ribosome synthesis occurs.
Answer:
For someone who doesn't know the importance of carrying capacity, i would advice him to understand what carrying capacity mean, and then tell him that he should not overcrowd the population of animals or be part of humans overcrowding as it can destroy the ecosystem or resources.
Explanation:
This is because, carrying capacity is the population size that can conviniently live in an habitat with the available resources..
It's very important because, it will ensure that the population size that the resources can sustain can live in the environment so as to prevent degradation of the ecosystem or the environment due to increase in population size.
A glucose molecule is a monomer of starch and cellulose
Answer:
<u> C) Each type of sensory receptor responds only to the stimulus that defines the receptor</u>
<u></u>
Explanation:
Neurons, specialized cells within the nervous system. These help with coordinated movement ad communication within the body through the transmission of electrical signals.
Sensory receptors are highly specialized neurons. These are able to detect various chemical and physical stimuli, and are classified by their ability to detect certain stimuli such as:
- photoreceptors
- mechanoreceptors
- chemoreceptors
- thermoreceptors
Sensory receptors respond to certain intensities of stimuli, instead of one specific stimulus. e.g. Mechanoreceptors within the skin can respond to pressure changes due to touch, but may also detect sound due to specific vibrations.
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.
