The removal of sections of RNA, called introns, occur at which regulation step in eukaryotic cells? (1 point)
o mRNA life span
O post-translation
O RNA processing
ochromatin remodeling
Answer:
post-translation
Explanation:
When a eukaryotic gene is transcribed in the nucleus, the primary transcript (freshly made RNA molecule) isn't yet considered a messenger RNA. Instead, it's an "immature" molecule called a pre-mRNA.
The pre-mRNA has to go through some modifications to become a mature mRNA molecule that can leave the nucleus and be translated. These include splicing, capping, and addition of a poly-A tail, all of which can potentially be regulated – sped up, slowed down, or altered to result in a different product.
Most pre-mRNA molecules have sections that are removed from the molecule, called introns, and sections that are linked or together to make the final mRNA, called exons. This process is called splicing.
In the process of alternative splicing, different portions of an mRNA can be selected for use as exons. This allows either of two (or more) mRNA molecules to be made from one pre-mRNA.
Answer:
RNA processing
Explanation:
RNA processing. Splicing, capping, and addition of a poly-A tail to an RNA molecule can be regulated, and so can exit from the nucleus. Different mRNAs may be made from the same pre-mRNA by alternative splicing.

What is the function of bile in the digestion of fats in the small intestine?
Answer:
Bile is a fluid that is made and released by the liver and stored in the gallbladder. Bile helps with digestion. It breaks down fats into fatty acids, which can be taken into the body by the digestive tract.
Explanation:
When digesting fats, bile acts as an emulsifier to break the large fat globules into smaller emulsion droplets. Emulsified fats provide a larger area for the fat-digesting enzymes (lipase) to act, making the process quicker. Bile acts as a good solvent.

Recent research has found that on one island of the Galapagos two finch species interbred. This interbreeding may have resulted in a hybrid species that ultimately led to the extinction of one of the species Darwin discovered. They call this speciation in reverse, or despeciation. Based on what you know about speciation, why are these terms appropriate?
Answer:
Speciation is defined as an evolutionary process in which one population evolves into a distinct species.
Speciation in reverse, or despeciation is defined as the extinction of an old species due to combining with evolved species to produce hybrid species but it conserves biological lineage.
In the given research, the term used despeciation or speciation in reverse is appropriate as hybrid species resulted from interbreeding of Galapagos two finch species conserved the biological lineage but also loss one of the species Darwin discovered.
Answer:
Speciation is the method by which unique species evolve from a common ancestor. In this case, two of these species that split from a common ancestor interbred and created a hybrid. This hybrid was apparently stronger and possibly better adapted to the environment, which led to extinction of a species formed by the initial speciation event.

Answer:
Explanation:
Benefits
Animals will not depend on plant source again for their food but have it produced directly by themselves because photosynthesis will allow animal produce their own food
Animal will get a direct source of energy for their activities. Energy is derived from food consumed after the food has been broken down in the body system of animal. Animal photosynthesis will give animals access to direct source of energy as the product their food.

A) The repressor will no longer bind to the operator.
B) The repressor will no longer bind to the inducer.
C) The lac operon will be expressed continuously.
D) The lac operon will function normally.
Answer:
D) The lac operon will function normally.
Explanation:
The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream. The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.so correct option is D) The lac operon will function normally.
If a researcher moved the repressor gene of lac I, along with its promoter; the lac operon will function normally. Option D is correct.
Promotor:
It is the genetic sequence that is recognized by the RNA polymerase to start the transcription.
Here, researcher moved the repressor gene of lac I , along with its promoter.
Therefore, transcription starts, it will express the repressor gene also because repressor gene was moved with promotor.

Biology Question
If the frequency of an autosomal dominant allele is 0.6 . Calculate the frequency of recessive phenotype in a population of 6000
Answer:
First thing is that word “autonomous” given in the question is actually “ autosomal”.
Now let's start solution:
Frequency of dominant allele “A” is denoted by p.
Here p = 0.6
Frequency of recessive allele “a” is denoted by q.
According to Hardy - Weinberg equilibrium
p + q = 1
Hence q = 1 - p = 1 - 0.6 = 0.4
Now in question what is asked is about frequency of recessive phenotype (aa).
According to Hardy - Wienberg equilibrium frequency of recessive phenotype is q2 (q square).
Frequency of recessive phenotype is = q2 = 0.4 x 0.4 = 0.16
Now Number of recessive phenotype in a population of 10000 is
= frequency of recessive phenotype x total population
= q2 x 10000
= 0.16 x 10000
= 1600

How does the movement of particles of matter change when temperature increases?
Decreases
Increases
Increases then decreases
Does not change
Answer:
Increases
Explanation:
The movement of particles of the matter increases with the increase in temperature.
The particles gain kinetic energy with increasing temperature and move in faster rate.
For example: When we blow a balloon with our mouth, we increases the temperature inside the balloon, the particles in the balloon gain kinetic energy that leads to the faster movement of gas particles in the balloon and they collide with each other and surface of balloon, after a peak the balloon get burst because of high kinetic energy and high collision.
Hence, the correct answer is "increases".

If the Gulf Stream stopped running, how would the climates of North America and Europe be affected?
Answer: Land would become infertile, habitat loss, & environmental changes
Explanation:
Because there wouldn't be alot of water to keep the soil moist, therefore the ground would begin to harden and get dry. :)
If the Gulf Stream stopped, the climates of North America and Europe would be colder and drier.
The gulf stream is a huge current of warm and fast-moving ocean water. This ocean current plays a key role in regulating temperatures across the globe and has an impact on the frequency and intensity of storms and rainfall. The collapse and stoppage of this stream will cause an array of problems, including but not limited to:
Reduced rainfallLower temperaturesFewer stormsAreas that would be particularly affected by this are North America and Europe. This is due to the direction that the gulf stream flows, carrying warm water along these boundaries.
The vast amount of warm water carried by this stream explains how it is able to affect the average temperatures of these coastal areas, with the disappearance of the stream, temperatures in North America and Europe would initially decrease.
The warm water carried by this current is also responsible for increased rainfall. Warm water on the surface of the ocean is heated by the sun and evaporates, creating clouds, which then provide rain. The absence of this current would dramatically affect cloud formation and reduce the amount of rain severely. This can lead to droughts and reduced agriculture.
Though Fewer storms may seem like a positive impact, it is not entirely. Storms play a crucial part (together with ocean currents) in regulating global temperatures, as well as provide a source of rainfall to end droughts and promote biodiversity in areas that depend on water and humid climates.
The gulf stream is important for maintaining climates and rainfall. If it were to stop, climates in North America and Europe would be colder and drier.
