a sample of human cells is suspended in a nutrient solution overnight. The next dasy, the scientist observes that the cells have

undergone high rates of division. Why does this lead her to suspect that the cells are cancerous

TEA [102]3 years ago

The question is incomplete as it misses the options which are:

Cancer cells do not exhibit density dependent inhibition

Cancer cells do not require growth factors

Cancer cells do not exhibit anchorage dependence

Cancer cells ignore typical cell cycle checkpoints

Answer:

The correct answer will be option- Cancer cells do not exhibit anchorage dependence

Explanation:

A cell becomes tumour forming cell or cancerous cell when the cell undergoes some mutation in the DNA which causes uncontrolled cell division without differentiation.

As a result of the mutation, these cancerous cells show various properties which are present in the normal cells nut absent in cancerous cells like the cancerous cells lack the anchorage dependence.

Anchorage dependence is the property of the cells or the group of cells in which the cells maintain their adherence to the other layer of cells to communicate with each other.

Thus, the cancerous cells lack the anchorage dependence

Answer:

Moving air masses cause the weather to change when they contact different conditions. For example, a warm air mass moving over cold ground may cause an inversion. ... Cold air masses tend to move toward the Equator. Warm air masses tend to move toward the poles.

Describe the process of skeletal muscle contraction by assembling the following 10 events in the proper order in paragraph form.
balu736 [363]

5) muscle fiber is stimulated at the neuromuscular junction triggering an action potential  

7) APs travel down the T-tubules to the sarcoplasmic reticulum  

Released acetylcholine (due to action potential within motor neuron) from the motor neuron initiates depolarisation within the sarcolemma, which is spread through the muscle fibre via T tubules.

8) in response to an AP, calcium ions are released into the cytosol/space around the myofibrils

Depolarisation causes the sarcoplasmic reticulum to release calcium ions necessary for the contraction

3) calcium ions bind to the T and T system

1) T and T system undergoes a conformational change, exposing the myosin binding sites on actin  

6) myosin head/cross-bridges bind to actin

The binding sites for the myosin heads located on actin, are covered by a blocking complex (troponin and tropomyosin) that can be unblocked by the calcium binding

2) myosin heads/cross bridges bind to actin and flex, shortening the sacromere  

4) actin filaments are pulled toward the center of the sacromere, shortening the muscle fiber  

As the individual sarcomeres become shorten the muscle fibres as a whole contracts

10) myosin head continues to attach, flex, release, extend, and reattach as long as calcium ions are present

9) calcium ions actively transported into the sarcoplasmic reticulum  

Relaxation of a muscle fiber occurs when a Ca ions are pumped back into the sarcoplasmic reticulum .
