Which level of primary control in the eukaryote gene activity involves changes in the polypeptide chain before?
The primary level of gene control in eukaryotes that involves changes in the polypeptide chain before translation is post-transcriptional modification. This refers to alterations made to the pre-mRNA transcript, such as splicing out introns and adding a 5' cap and poly-A tail. These modifications prepare the mRNA for translation into a functional protein.

What happens to the sun every 11 years?
The sun goes through a solar activity cycle known as the solar cycle or solar magnetic activity cycle. This 11-year cycle involves changes in the sun's magnetic field, sunspots, solar flares, and coronal mass ejections. These changes can affect space weather and impact Earth's magnetic field and communications systems.
What mechanism is used to finely tune enzyme activity according to the needs of the cel l?
Allosteric regulation is a mechanism commonly used to finely tune enzyme activity. This involves the binding of a molecule at a site other than the active site, leading to a change in enzyme conformation and subsequent modulation of its activity. By responding to changes in the cellular environment, enzymes can maintain proper levels of activity to meet the cell's metabolic demands.
Which genetic change is best described by the following statement A random change in the base sequence of DNA results in an alteration of a polypeptide?
A point mutation is best described by this statement. Point mutations occur when there is a change in a single nucleotide base in the DNA sequence, which can lead to changes in the corresponding amino acid sequence of a polypeptide during protein synthesis.
Can you increase activity of an enzyme by decreasing pressure of the system?
Decreasing pressure in a system generally affects enzymatic activity only in specific contexts, such as when the enzyme-catalyzed reaction involves gaseous substrates or products. In most cases, enzyme activity is more directly influenced by factors like temperature, pH, and substrate concentration. While lowering pressure might alter the equilibrium of certain reactions, it typically does not lead to a general increase in enzyme activity. Therefore, the effect of pressure changes on enzyme activity is highly dependent on the specific reaction and conditions involved.
Are changes in chromatin structure and histone DNA binding associated with gene activity?
yes
What is one human activity that changes the popularity of a ferret?
A human activity that changes the popularity of ferrets (or other animals) if they were featured in a movie
Cost behavior refers to the manner of what?
changes as the related activity changes.
The euphoric effects of amphetamines result from changes in?
changes in dopamine activity
A variable cost changes in proportion to changes in the volume in activity?
the answer is Variable Cost
How can I edit a Strava activity?
To edit a Strava activity, log in to your account, go to the activity you want to edit, and click on the pencil icon. From there, you can make changes to the activity details such as the title, description, and privacy settings. Remember to save your changes before exiting.

What kind of drug Changes activity of neurotransmitters?
antidepressants
Is ripening of banana a physical or chemical change?
Ripening of a banana is a chemical change. It involves the breakdown of complex molecules in the banana fruit into simpler molecules due to enzymatic activity, resulting in changes in color, texture, and flavor.
Can Meditation produces observable changes in brain activity.?
Yes, studies have shown that meditation can lead to observable changes in brain activity, such as increased gray matter density in certain areas, changes in neural connectivity, and reduced activity in regions associated with stress. These changes are linked to improvements in cognitive functions, emotion regulation, and overall well-being.

Which phrase best describes translation?
Translation is the process of converting text from one language to another while retaining the meaning and tone of the original content.
What is the name for temperature changes which involves no heat transfer?
Adiabatic
