Explanation:
A student hypothesized that EC growth might be affected by the DNA from circulating erythrocytes. Is this student’s hypothesis reasonable?
Answer:
Explanation:
It can be said that this hypothesis is actually not reasonable because circulating erythrocytes do not contain DNA. This can be proven by the Mammalian erythrocytes (rbcs) which ultimately loose their nuclei as well as many other organelles during their maturation process and they don't have nuclei or mitochondria meaning that they are not affected by the DNA.

In the image, the arrow Is pointing to a celestial object. Which attribute disqualifies the object from being a planet?
A. It appears to have no moons.
B. It is spherical in shape.
C. Its neighborhood is not clear.
D. It has horizontal bands on its surface.
The correct answer is C. Its neighborhood is not clear.
Explanation:
One of the key features of a planet is that it clears its neighborhood; this means the planet gravitational force is strong enough that there are no other celestial bodies on its orbit or next to it except by its moons or satellites. This does not occur in the image presented because there are smaller celestial bodies near to the main or bigger celestial body. This likely occurs if the celestial body is not big enough to clear its neighborhood, and therefore it is not a planet.

Identical twins are formed from one fertilized egg, but fraternal twins form from two different fertilized eggs. Apply your knowledge of mitosis and meiosis to explain the genetic differences between identical and fraternal twins.
Answer:
Identical twins share the exact same DNA while fraternal twins do not.
Explanation:
Mitosis is the type of cell division that results in 2 individual cells that have the exact genetic material.
Meiosis is the division of reproductive cells, eggs and sperms, which results in new cells with half the amount of genetic material and that makes them unique.
Identical twins are twins developed from a single egg that has been fertilized with a single sperm, meaning they have the same DNA.
Fraternal twins are twins from two different eggs that have been fertilized by two different sperms and grow in the womb at the same time with no additional cell division. So they have different DNA's.
I hope this answer helps.
The formation of fraternal twins takes place when the female generates two eggs and identical twins takes place when the female generates one egg and the zygote divides into two spontaneously.
• In identical twins case, the zygote goes through cleavage, that is, cell division by mitosis, when embryo is at the stage of two cell.
• The separation of two blastomeres may take place and then each act as an independent zygote.
• This each dissociated blastomere give rise to a novel independent individual.
• The production of both the organisms takes place due to mitosis, thus, both would possess identical genetic makeup and are known as identical twins.
• Identical twins would be either males or would be either females.
• In case of fraternal twins, the female generates more than one eggs. And all the eggs get fertilized independently by the sperm.
• Thus, formation of two or more zygotes takes place, and each zygote give rise to new offspring.
• These offsprings possess distinct genetic combinations, and such offspring are known as fraternal twins.
• They are produced sexually, and fraternal twins can possess different genders as they do not possess similar genetic recombination.
Thus, identical twins is formed from one egg and the zygote gets divide into two, while fraternal twins formation takes place when two eggs are generated by the female.

Which of the circumstances below most accurately describes conditions that are likely to permit a robust anti-tumor adaptive immune response?
a. A tumor with high expression of proteins that have mutations in sequences encoding HLA-binding peptides.
b. A robust acute inflammatory response to PAMPs expressed specifically by tumor cells.
c. Anti-tumor T lymphocytes that have high expression of CTLA-4.
d. A tumor with high expression of PD-L1.
Did you ever figure out the answer to this question?
The study of PAMP-DAMP complexes is vital to the advancement of knowledge regarding inflammatory disorders in general and cancer in particular. Therefore, option (B) is correct.
What is PAMP-DAMP complexes?Increasing evidence links inflammation to cancer, and at the root of inflammation are PAMPs and DAMPs (DAMPs). Microorganisms contain PAMPs, which are detected by pattern recognition receptors on monocytes and DCs (PRRs). PRR activation produces pro-inflammatory cytokines.
A robust immune response requires endogenous chemicals that pose 'risk' to self-tissues and are created by injured or stressed cells; these are DAMPs, which also trigger inflammation. PAMPs and DAMPs each have about 100 receptors. PAMPs and DAMPs interact; a PRR can bind to both. In this system, PAMPs and DAMPs affect each other's activation threshold. Thus, PAMP-DAMP relationships describe inflammation in a predictable 'inflammatory code'

If a person had not drunk any water for 8 hours before collecting a sample, would you expect his/her urine to have a high or low specific gravity? Why?
Answer:
The person’s urine will have a high specific gravity
Explanation:
A high specific gravity is characterized by an increased concentration of solutes in the urine of am individual. A low specific gravity is characterized by a low or decreased concentration of the solutes.This is usually due to dehydration as a result of environmental conditions or tedious physical activities.
This explains why a person who had not drank any water for 8 hours and is dehydrated before collecting a sample is thought to have a urine with a high specific gravity

The ____ ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the ______ bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.
Answer:
The purine ring is built onto ribose-5-phosphate of PRPP for its de-novo nucleotide biosynthesis, while the ring structure of the pyrimidine bases are synthesized separately and then coupled to ribose-5-phosphate via the C-N glycosidic bond.
Explanation:
In the de novo synthesis of nucleotides, their metabolic precursors such as aminoacids, ribose-5-phosphate, CO₂ and NH₃ are used as starting materials.
In purine nucleotide synthesis, the ring structure is built up on ribose-5-phosphate of PRPP by addition of one or a few atoms one at a time starting with the amino group donated by glutamine until the first intermediate inosinate is synthesized.
In pyrimidine ring synthesis, orotate is first synthesized from carbamoyl phosphate and aspartate, and then is attached to ribose-5-phosphate of PRPP, before it is then converted to the common pyrimidine nucleotides starting from uridylate.
For this task, you will imagine that you are a reporter for a scientific magazine. Your task is to explain the process of protein synthesis to someone who does NOT have a science background. Therefore, the explanation needs to be in simple enough terms for anyone to understand. You will organize your article in the following way: Structure and Function of DNA and RNA Transcription and RNA processing Translation Protein modification (general) You must also include the following terms: Double helix Helicase Codon Polymerase 5’ cap Poly (A) tail Introns Exons Splicesomes rRNA, tRNA, Mrna Ribosomes Anticodons E site, P site, A site Initiation Elongation Termination
Answer:
Please find the explanation below
Explanation:
Our nucleus is made up of a genetic material called deoxyribonucleic acid (DNA), which is a double-helical structure that stores the genetic information needed for the optimal functioning of any organism. DNA, alongside RNA are nucleic acids that are composed of NUCLEOTIDES subunits. The nucleotide consists of a pentose sugar (deoxyribose in DNA and ribose in RNA), nitrogenous base and a phosphate group.
However, the genetic information stored in the DNA molecule needs to be expressed in order to form useful products (proteins). This genetic expression is done in two stages viz: transcription and translation. Transcription, which is catalyzed by an enzyme called RNA polymerase is the process whereby the information stored in the DNA is used to synthesize a mRNA molecule. However, this mRNA molecule is considered pre-mature until it is processed. RNA processing occurs in three stages viz: 5' capping, polyadenylation, and splicing.
5' capping involves adding a 5' cap to the marks molecule. Polyadenylation involves adding a poly(A) tail to the mRNA molecule while splicing is the removal of introns (non coding regions) with the aid of Spliceosomes and joining of the exons (coding region). After processing, the mRNA becomes matured and ready to be translated.
Translation is the process whereby the mRNA transcript is used to synthesize a protein molecule. It occurs in the ribosomes (organelles for protein synthesis, a complex of rRNA and proteins) where the mRNA is read in a group of three nucleotides called CODON. The reading is done by the Anticodon of a transfer RNA (tRNA), which is complementary to the codon.
Translation occurs in three stages: initiation, elongation and termination. The mRNA attaches to the P site of the ribosomes (initiation) where it is attached to by a tRNA's anticodon complementary to it. The anticodon carries the amino acid corresponding the codon and shifts to the A-site. The addition of amino acid to the polypeptide chain continues (elongation) until a stop codon is encountered, which signals the end of the translation process i.e. termination. This causes the polypeptide (protein) to be released from the E-site.
The synthesized protein undergoes packaging and modification in the Golgi apparatus.
Have you ever noticed that aside from zoos, you don't see kangaroos, wombats, and koala bears outside of Australia? This is because there is a trench that is a "biogeographical transition zone between Asian and Australian flora and fauna". What is the name of that trench?
Answer:
Wallace Line
Explanation:
Wallace Line is a boundary line which is a transitional zone between Asia and Australia. This boundary drawn by the British naturalist Alfred Russel Wallace in 1859. This boundary restricts the transferring organisms such as flora and fauna from Australia to Asia. So that's why kangaroos, wombats, and koala bears are only present in Australia not in the continent of Asia.

Intrinsic factor A. increases gastric motility. B. causes the release of stomach acid. C. facilitates the absorption of vitamin B12. D. protects the stomach lining from the effects of stomach acid. E. stimulates the synthesis of DNA.
Answer:
C. facilitates the absorption of vitamin B12.
Explanation:
The Intrinsic factor is a substance that is produced by the stomach and it has the important function of producing vitamin B12 which is necessary for life. Vitamin B12 is used in the production of mature red blood cells. It also improves the function of the nervous system. The production of this intrinsic factor is a very vital role of the stomach because, in the absence of a stomach, for example, in the case of a gastrectomy, a person can only survive if he is given injections of Vitamin B12.
The stomach also serves as a holding center for food and eventually delivers the food to the small intestine and the duodenum.

You have been assigned a DNA stretch. What is the complementary strand when you replicate the template
Answer:
The complementary strands of a DNA are read in the opposite direction to one another
Explanation:
A DNA strand/stretch can be represented with a number of bases. The bases in a DNA strand are Adenine (A), Thymine (T), Cytosine (C) and Guanine (G). The Adenine can bind to Thymine (and vice-versa) while the Guanine can bind to Cytosine (and vice versa). These bonded bases are called "base pairs".
Complementary DNA strands are read in opposite direction to one another. Each end of a DNA strand is either a 5' end or a 3' end. Hence, if one strand runs from the 5' to 3' end, the complementary strand will run from the 3' to 5'. Thus, they are represented "on paper" the way they run.
For example,
If the DNA strand assigned is AGTCTAG running 5' to 3', the complementary strand will be CTAGACT (starting from the 3' end) and NOT TCAGATC (which starts from the 5' end)

What substance heats up the fastest: water, dry sand, wet sand, rock
Answer:
The specific heat capacity represents the amount of energy, in joules, that it takes to raise the temperature of one gram of a given substance by one degree Celsius. Put more simply, the amount of energy it takes to raise a quantity of water by one degree Celsius would raise an equivalent quantity of sand by a little over 14 degrees. Likewise, sand does not need to lose nearly as much energy as water to produce equivalent cooling. Since it "holds" a lot less energy, it cools down much faster than sand.
Indeed, liquid water has an unusually high specific heat capacity. Because it is much less prone to temperature swings than other common substances, large bodies of water often work to moderate temperatures in a region. This helps to explain, for example, why average temperatures fluctuate very little over the year in San Francisco, a cit
