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.
Describe the parts of the building blocks of lipid
Answer:
Glycerol and fatty acids are the basic building blocks of fats (lipids). Fats are the product of the esterification of the trivalent alcohol glycerol with fatty acids of different lengths (between 12 and 20 carbon atoms). Two important representatives of the lipids are triglyceride (90% of fats) and cholesterol.

Answer:
This question lacks options, options are:
A) cerebral cortex.
B) basal nuclei.
C) sensory pathways.
D) motor pathways.
E) All of the answers are correct.
The correct answer is E.
Explanation:
The cerebral cortex processes and filters its information before passing the most relevant aspects to other regions of the brain. Some of these brain regions, in turn, send information back to the cortex. These loops, known as 'feedback systems', are considered essential for the functioning of cortical networks and their adaptation to new sensory information. Neural circuits must first assess the importance of incoming sensory information and then refine how it is processed in the future. Positive feedback, triggered with the purpose of amplifying the response to the initial stimulus, can be compared to a chain reaction or a vicious circle. Few are the functions regulated by this mechanism; rather it is triggered in pathological situations. It is the system by means of which the organism very rarely regulates any of the bodily functions under normal conditions, making the initial stimulus to be maintained and even increased. This type of mechanism is predominantly present in pathological situations: Its constitutive elements are: stimulus, receptor, afferent pathway, integrating center, efferent pathway, effector and response. The response does not have the ability to satisfy the initial stimulus.

If bacteria transformed with a recombinant pUC18 plasmid produce white colonies when grown on plates containing ampicillin and Xgal, which of the following is least likely?
a. They produce β-lactamase that provides resistance to ampicillin.
b. They carry a vector that contains a DNA fragment inserted into the multiple cloning site.
c. They produce functional β-galactosidase that cleaves X-gal.
d. They carry a vector with a lacZ gene that has been disrupted and rendered nonfunctional.
e. They carry a vector with the bla gene used as the selectable marker.
Answer:
c. They produce functional β-galactosidase that cleaves X-gal.
Explanation:
β-galactosidase is an enzyme capable of catalyzing the enzymatic hydrolysis of β-galactosides into monosaccharides by hydrolyzing the β-glycosidic bond. On the other hand, X-gal is an analog of lactose composed of galactose, which is widely used in laboratories for the detection of β-galactosidase. In the presence of β-galactosidase, X-gal is hydrolyzed by cleaving its β-glycosidic bond, thereby confirming the presence of β-galactosidase.

Explanation:
Place the following materials in the order in which they are likely to fossilize. Begin with the material that is most likely to fossilize, and finish with the material least likely to fossilize.
1. mammal teeth
2. bones of an adult mammal quickly buried
3. bones of an adult mammal left on the surface
4. soft body parts of any animal
Answer: correct order--->
1)mammal teeth
2.)bones of an adult mammal quickly buried
3.) bones of an adult mammal left on the surface
4.)soft body parts of any animals
Explanation:
Fossilization is the ability of an organism to be preserved and remain unaltered for a very long time. Through research , it has been found out that Harder parts of the body tend to remain preserved for a long time because they naturally have minerals deposited in them and may only be reduced, but the softer part or tissues do not get preserved for a long time because being made up of polymer can be disintegrated easily by natural biological and physical processes.
The order of which material will likely fossilize is
1.)mammal teeth
2.)bones of an adult mammal quickly buried
3.) bones of an adult mammal left on the surface
4.)soft body parts of any animals
Reason,
--Teeth and bones biologically contain calcium but the teeth is more tougher and durable than the bone, Even when a body is decomposed, the teeth most times are not affected at all.
Bones of an adult mammal left on the surface will decompose faster than the one buried because of the biological (natural decomposing ) and physical processes(temperature, wind, sunglight, rainfall ) which will both act on it at the same time because of its exposure.
- soft body parts of any animals will decompose fastest as bacteria will feed on it immediately since it lacks minerals that can elongate preservation.

Distinguish between the 4 major modes of nutrition of prokaryotes and identify each modes energy source and carbon source as well as giving an example
The four major modes of nutrition in prokaryotes are photoautotrophic, chemoautotrophic, photoheterotrophic, and chemoheterotrophic. Their differences, energy source and carbon source are explained below:
WHAT ARE PROKARYOTES?
Prokaryotes are a group of organisms that do not have their genetic material enclosed in a membrane bound NUCLEUS. They include bacteria, archeae etc.METABOLISM IN PROKARYOTES:
All organisms, prokaryotes inclusive, need energy for their metabolic activities. They also need carbon. Hence, based on their carbon and energy source, prokaryotes can be:
Photoautotrophic: These are prokaryotic organisms that use carbon dioxide as their carbon source and light as their energy source. Example iscyanobacteria.
Chemoautotrophic: These are prokaryotic organisms that act on inorganic substances as energy source and use carbon dioxide as carbon source. Example is Nitrosomonas bacteria.Photoheterotrophic: These are prokaryotic organisms that use light as source of energy but obtain carbon from other organisms (organic sources). Examples are heliobacteria, sulfur bacteria.Chemoheterotrophic: These are prokaryotic organisms that act on inorganic substances as energy source but derive their carbon source from organic compounds (other organisms).Learn more: https://brainly.com/question/6103977

What do amino acids, fatty acids, and sugars (monosaccharides) have in common?
A. They are made of carbon, oxygen, and nitrogen.
B. They are made of carbon, oxygen, and hydrogen.
C. They are used to make lipids.
D. They are used to make proteins.
Answer:
Explanation:
C. They are used to make lipids.
What amino acids, fatty acids, and sugars (monosaccharides) have in common is that they are made of carbon, oxygen, and hydrogen which is option B.
Amino acids are the basic structural units of proteins. Each amino group (-NH₂) and a carboxyl group (-COOH) in its molecule. Thus, from the molecular structure of an amino acid, the carboxyl group of the molecule contains carbon, oxygen and hydrogen elements.
Fatty acids are commonly found in lipids ans are made up of long chain alkanoic acids of general formular, RCOOH where R contains about 10 to 18 carbon atoms. the terminal -COOH group contains carbon, oxygen and hydrogen elements.
Sugars (monosaccharides): they are naturally occuring organic compounds containing carbon, hydrogen and oxygen, with the hydrogen and oxygen present in the ratio of 2:1. The general formula for monosaccharides is C₆H₆O₁₂.
Therefore, amino acids, fatty acids, and sugars (monosaccharides) have carbon, oxygen, and hydrogen in common.

Peer review involves subjecting the author's scholarly work and research to the scrutiny of other experts in the same field to check its validity and evaluate its suitability for publication. A peer review helps the publisher decide whether a work should be accepted.
why can animals move and plants can't?
Answer:
Plants make their own food from sunlight, water, and carbon dioxide (part of the air). Making food like that is slow, so if they moved around too quickly, they'd starve to death. So, though they do move, it's usually very slowly.
Animals get their food from plants or from other animals. Moving around is a way for them to get more food, not just to use it up. It's also a way to avoid getting eaten.
(Even plants which appear to "eat" food, such as a venus flytrap, are actually only getting vitamins and minerals that way, not extra energy.)

Paleobiologists generally recognize the five most severe mass extinctions during the Phanerozoic Eon. Along with the other students in this class, determine when each of these “Big Five” mass extinctions occurred. Include in the discussion a brief list of which organisms went extinct during each of these events and which organisms radiated afterwards. You should use the information from this unit and from Internet searches to help you in this discussion. NO plagiarism will be permitted.
Extinction of the Ordovician: This extinction was responsible for the disappearance of about 60-70% of the species of oceanic life, This is because in that period most of the life on Earth was in the ocean. This extinction is believed to have been caused by an intense glacial period, although short that froze most of the planet's water. It is believed that the species most affected were sponges, algae, jawless fish, molluscs and cephalopods.
Devonian Extinction: Responsible for the disappearance of about 75% of marine species. This extinction was caused by the depletion of oxygen in the ocean, making life impossible for all aerobic marine organisms. This depletion of oxygen was caused mainly by the variation in the level of the ocean and climatic changes that may have been caused by asteroids.
Permian Extinction: Responsible for the death of 95% of life on earth. This extinction is known as the "mother of all extinctions" due to its destructive character, which devastated life on land and in the ocean. It is believed that this extinction was caused by volcanic activities triggered by the impact of asteroids. Almost all living species on earth were affected, such as insects, trilobites, sharks, boneless fish, reptiles, among others.
Extinction of the Triassic: It is not known exactly what caused this extinction, but it is estimated that it had the power to decimate 70-80% of terrestrial life, mainly arcosaurs and amphibians. The most accepted theory today is that the extinction was caused by recurrent volcanic activities that influenced huge volumes of carbon dioxide in the atmosphere, generating intense heating.
Cretaceous extinction: It was caused by the impact of an asteroid with the earth. The impact had the power to exterminate 75% of terrestrial life. This is the most well-known extinction, since it was responsible for decimating dinosaurs, however, some animals survived this impact, such as most marine species, frogs, birds, reptile and mammals.

a. use two fingers to attempt to reduce the mass.
b. palpate the left scrotum simultaneously.
c. lift the right testicle and then compare pain level.
d. transilluminate the mass
Answer:
d. transilluminate the mass
Explanation:
Sometimes, painless hard or tender mass develop in the scrotum of men and can cause testicular tumors.
After detecting a scrotal mass, to reduce the size of the mass, the next assessment required is to transilluminate the mass in which testicles will be appear opaque on transillumination. Transillumination of mass will help to detect the orientation of mass which can be treated further.
Hence, the correct answer is d. transilluminate the mass
