Which of the following best describes cell communication processes that are present in bacteria, yeast, and multicellular organi
sms? They carry out synaptic signaling, in which neurotransmitters are released and cause a response in nearby target cells.
They have gap junctions that allow molecules to pass through the cell wall without having to cross the cell membrane.
They produce hormones, which travel to neighboring cells and carry out local regulation processes.
They release chemical messengers to communicate with cells they may or may not be in direct contact with.
They release chemical messengers to communicate with cells they may or may not be in direct contact with.
Explanation:
Unicellular organisms such as bacteria or yeast, 'talk' to each other through the release of chemicals. In bacteria, this is known as quorum sensing which allows them to determine the surrounding bacterial population density. In yeast, one of the more popular pathways is known as the mating factor pathway, which allow the organisms to find mates. Whereas, in multicellular organisms (such as humans), this chemical release allows for cell-cell co-ordination which keeps the system functioning correctly.
Well, the cell would be out of energy! The mitochondria plays a very important role in cell functions. With out it, it cannot do whatever job that needs to be acquired.
Trend analysis is a technique which is used during technical analysis in the prediction of the prices of future stocks based in the currently observed trends. The basic idea behind the trend analysis is the success or failure of a trade in future can be estimated by the conditions of the trade in past. Thus in this analysis the upward or downward growth trend of a business is used in prediction of future of business and in this way it is helpful for the investors to be sure that they should invest their money in the business or not.
