Answer:
The correct answer will be acquired traits can be passed to offspring.
Explanation:
Lamarck is known for his idea of "inheritance of acquired traits" by studying neck size of giraffes and stated that:
1. New organs or traits can be produced by long use during lifetime as response to external environment,
2. characteristic is inherited to the next or succeeding generations.
3. Organ can disappear if not used.
Scientists were not able to find and explain evidence for the theory for example :
1. The blacksmith’s arm- enlarges when used continuously against external resistance like weight of the hammer but it is not necessary that the smith’s children at birth would have large arms or later in his life.
2. Skilled Hands of a musician- skillful hands of a musician causes no increase in the size of the fingers and this trait might be passed to musician’s children and they also play instrument skillfully with no practice.
Thus, acquired traits can be passed to offspring is the correct answer.
Answer:It would take 300 years.
Explanation: Light years are how much light travels in a year. Thus it would take 300 years for light to travel to earth if a star is 300 light years away.
blockade of the human ether-a-go-go-related gene (hERG) encoded rapidly activating delayed rectifier potassium (IKr) of cardiac cells
<h3>
What are human ether-a-go-go-related gene (hERG)
?</h3>
- The rapidly activating delayed rectifier potassium channel's pore-forming component is encoded by the human ether-a-go-go-related gene (hERG) (IKr).
- Acquired long-QT syndrome, which puts people at risk for ventricular arrhythmias and sudden death, is mostly caused by drug- or illness-mediated alteration of hERG activity.
- Abuse and fatality rates related to fentanyl have been on the rise recently, raising severe health concerns.
- We looked into how fentanyl affects the hERG channel because it frequently results in abrupt death.
- We also looked at the effects of norfentanyl, the primary metabolite, and naloxone, an antidote for fentanyl overdose. HEK293 cell currents of hERG channels that were persistently expressed were captured using the whole-cell voltage-clamp technique.

Hydrogen peroxide is a natural byproduct of cellular metabolism in the human body. This product can be considered a free radical.
<h3>What is free radical?</h3>
A free radical may be described as any molecular species able to impartial life that consists of an unpaired electron in an atomic orbital. The presence of unpaired electron effects in sure not unusualplace homes which can be shared via way of means of maximum radicals. Many radicals are volatile and especially reactive.
These free radicals were recommended to be chargeable for reperfusion-triggered cardiac lovely and reperfusion-triggered arrhythmia. Hydrogen peroxide (H2O2) is frequently used as an experimental supply of oxygen-derived unfastened radicals.
