Normal cells responds to contact inhibition. When they come into contact with other cells, they stop moving and dividing. This k

eeps the cell contained within their own tissues. How did the mutated (cancer) cells show the evidence that they do not respond to contact inhibition?

Answer:

Cancer is basically a disease of uncontrolled cell division. Its development and progression are usually linked to a series of changes in the activity of cell cycle regulators. For example, inhibitors of the cell cycle keep cells from dividing when conditions aren’t right, so too little activity of these inhibitors can promote cancer. Similarly, positive regulators of cell division can lead to cancer if they are too active. In most cases, these changes in activity are due to mutations in the genes that encode cell cycle regulator proteins.

Match these cell division phases with the appropriate processes:
Komok [63]

Answer:

1) Break down of the nuclear membrane allowing mitotic spindles to connect to kinetochores:A. Metaphase

2)APC degrades securin which allows separase to become active which degrades the cohesin rings: E. Anaphase

3) Dephosphorylation of nuclear pore and lamins: F.Telophase

4) cleavage of plasma membrane by actin and myosin contractile ring:D.Cytokinesis

5) copying of the genome:C. Interphase

6) formation of the metaphase plate:B. Prometaphase

What role do decomposers play in maintaining the carbon cycle shown above?
jarptica [38.1K]

Answer:

Decomposers help reclaim carbon from dead organisms and put it back into the carbon cycle so living organisms can use it. Decomposers break down dead plants, animals and waste products. This process releases carbon dioxide through cellular respiration

Decomposers are organisms that occupy the last link in a trophic web. They feed on dead organic matter, returning nutrients to the soil. The decomposers in this trophic web are Mooshroom.

<h3>What is a decomposer in a trophic web?</h3>

Decomposers are organisms that occupy the last link in a trophic web. These are the species that feed on dead organic matter.

Decomposers use the energy and matter found in dead tissues to grow and reproduce. They turn this matter into inorganic matter by remineralizing it. This is how it goes back in the soil nutrient cycles.

Although several species occupy the decomposers link, some common examples are earthworms, bacteria, and fungi.

In the exposed example, we can identify the following trophic levels,

  1. Producers  ⇒  Bear sedge and Bilberry
  2. Herbivores ⇒ brown lemming, actic fox
  3. Carnivore ⇒ acrtic fox, weasel
  4. Carnivore ⇒ Owl
  5. Decomposer ⇒ Mushroom.

The decomposer is the mushroom, that feed on dead organic matter of all the other organisms.
