10 POINTS !!! Why is it risky to build something whose natural frequency can be matched byexternal vibrations?

Answers

Answer 1
Answer:

It is risky to build something whose natural frequency is matched with external vibrations because of  ;  The effect of resonance

When an object constructed has a natural frequency which is equal to the frequency of a nearby external vibration, the amplitude of the vibration of the object will increase due to the resonance effect which occurs because the external frequency matches up with the natural frequency of the constructed object.

The negative effect of resonance is the increase in the amplitude of the vibration of the object which might lead to the partial or complete collapse of the constructed object.

Hence we can conclude that It is risky to build something whose naturalfrequency is matched with external vibrations because of  ;  The effect of resonance

Answer 2
Answer:

Answer:Most objects have at least one natural frequency of vibration. If a nearby object vibrates at the same frequency, it can cause resonance. Resonance is an increase in amplitude of a vibration that occurs when external vibrations match an object's natural frequency.

d. Pluripotency markers  

Explanation:

Pluripotency can be defined as the capacity of individual cells to differentiate into any cell type. Pluripotent transcription factors are pluripotent proteins that promote the differentiation of embryonic stem cells (ESCs) into stem/progenitor cells by inducing the expression of target genes, which are also capable of maintaining their pluripotent state. For example, SOX2, OCT4 and NANOG are pluripotent transcription factors highly expressed in ESCs in order to maintain the pluripotent state of these cells.

Attentional Blink is a phenomenon characterized by the individual failing to detect a second visual stimulus that is presented _____ milliseconds after the first stimulus

Answers

Answer:

200 to 500 milliseconds

Explanation:

Attentional blink is a phenomenon that puts time-related limitations to the ability to utilize visual attention. When an individual must identify two visual stimuli presented one after another, the accuracy is very poor for the second stimulus if it occurs within 200 to 500 milliseconds of the first stimulus.

So, in our question, the gap is filled by 200 to 500 milliseconds.

Answers

Answer:

The correct answer will be- Cargo vesicles

Explanation:

The product of the gene expression is known as the protein which is formed as the result of the transcription and translation.

The process of translation takes place in the ribosomes attached to the endoplasmic reticulum after which the proteins enter the lumen of the endoplasmic reticulum.

The protein then enters the secretory pathway which represents the movement of proteins by packaging them in cargo vesicles attached with the cargo proteins.

Thus, Cargo vesicles are the correct answer.
