You have a dish of mammalian cells in culture that are all about to enter mitosis (it is a synchronously replicating culture of

mihalych1998 [28]

Answer:

Option-A

Explanation:

RhoA is a protein which belongs to the Rho GTPase family proteins and related Ras superfamily. The Rho A protein is involved in the cell division before the cytokinesis as they are involved in the formation of cytokinesis structures like the actin-myosin rings and the contractile ring formation.

In the given question, if the drug inhibits the activity of RhoA, therefore, cytokinesis will be affected and the cell will complete all the stages of Mitosis except cytokinesis. The cells will be mostly observed in the telophase as cytokinesis will take place after that.

Thus, Option-A is correct.

The whitebark pine trees are key producers in the Yellowstone ecosystem. Predict what would happen to the bear population if hal

pentagon [3]

Answer:

White-bark pine trees:

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:

Effects due to decreased level of White-bark pine trees:

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.

May cause the decrease in population of the wild life:

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.

Decrease level of vegetation in the region:

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.
