Answer:
Vesicoureteral reflux (VUR)
Explanation:
Answer:
The condition is known as Vesicoureteral reflux (VUR)
Explanation:
Vesicoureteral reflux (VUR) is a pathological condition caused by Urinary Tract Infections (UTIs) where urine flows back from the bladder into one or both ureters, and sometimes back into the kidneys. The condition is commonly seen in young children under 2 years of age, and infants.
Most children with primary VUR were born with an abnormal ureter, which is mainly seen as a defective valve between the kidneys and the ureters that does not close well, hence resulting in refluxes. Secondary VUR develops due to some pathological conditions affecting the urinary tract, like blockage of the urethra, causing reflux of urine. Defective bladder nerves can also lead to VUR.

Describe at least 2 benefits and 2 drawbacks there might be for animal cells (including humans) to make their own food through photosynthesis.
Answer:
here.
Explanation:
Benefits would be that we'd be autotrophs, meaning that we'd be independent of an external source of organic compounds for energy. All we'd need is the sun and carbon dioxide. It's a simpler and less energy-consuming process than having to undergo digestion, absorption and then assimilation.
Cons would include the fact that it provides a very limited amount of energy only for the day. Which means humans will be inactive at the night time because the energy won't be able to support our activities. Since we don't have a surface area as big as leaves, our deep cells (like those of our organs and bones) will suffer most from the lack of energy since sunlight cannot penetrate our fat, muscles and bones. This can cause organ failure if our cells solely depended on diffusion.
Our high metabolic rate and our need for energy makes photosynthesis very very ineffective.

Explanation:
g UV radiation causes covalent dimerization of two subsequent ______ bases in DNA. This dimer is recognized and repaired by ______.
Answer: The options are not given.
Here are the options.
a. C and C ;;;; DNA photolyase
b. T and T ;;;;; DNA photolyase
c. C and C ;;;; DNA photoisomerase
d. T and T ;;;;; DNA photoisomerase
e. None of the above
Explanation:
UV light damages the DNA of cells that are exposed by making bonds to be formed between adjacent pyrimidine bases, usually thymines, in the DNA chains. The thymine dimers inhibit or hinder the DNA correct replication during reproduction of the cell.
UV radiation causes covalent dimerization of two subsequent T and T because Thymine bases of DNA directly absorbs a UVB photon . UVB light causes thymine base pairs close to each other in genetic sequences to bond together into pyrimidine dimers, thereby causing a disruption in the strand, which reproductive enzymes cannot copy.
UV-induced thymine dimers can be repaired by photoreactivation, in a process where energy from visible light is used to split the bonds forming the cyclobutane ring through the action of DNA photolyase, an enzyme that repaired damaged cause by uv radiation to dna.

Why are G proteins known as guanine nucleotide-binding protein?
Answer:
G proteins, also known as guanine nucleotide-binding proteins, are a family of proteins that act as molecular switches inside cells, and are involved in transmitting signals from a variety of stimuli outside a cell to its interior. ... G proteins belong to the larger group of enzymes called GTPases.
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.

Explanation:
In the box provided explain why living organisms contain more hydrogen atoms than any other atoms yet 65% of a typical organisms mass is oxygen
Answer:
The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.
Explanation:
This means that A orginasim will appear to contain more oxygen, but the size diffrence will mean that there will be more hydrogen, just of a smaller size with less mass, thus making up a lesser part of the organism in terms of mass, but the majority on the molecular level.
Answer:
Reason 1: The mass of Oxygen is 16 times that of Hydrogen. Hydrogen takes 16 atoms to equal the mass of 1 Oxygen atom.
Reason 2: A large portion of an organism’s mass is in the form of water. Water contains two hydrogen atoms and one oxygen atom.

Explanation:
he most common source of osteomyelitis is an infection that migrates via the bloodstream. direct invasion from a fracture. surgical contamination. a joint prosthesis.
The correct answer is A. An infection that migrates via the bloodstream
Explanation:
Osteomyelitis is a serious condition, in which an infection develops in bones. This causes symptoms such as pain, inflammation, and can lead to the spread of the infection to other tissues or bone necrosis if it is not treated. In terms of causes, this condition develops when the bone is exposed to bacteria or similar that causes the infection, this can occur during surgeries or fractures. However, the most common source of infection is via bloodstream this means the bacteria or germ is in the blood and it enters the bone through the bloodstream. Also, once the bacteria or germ is in the bone it causes the infection.
When discussing magnetic fields we could say that
metals can become magnetic if they have many spinning electrons that create magnetic fields
O metals are magnets because they have more electrons than non-magnetic materials
O non-paired electrons spin in opposite directions creating a magnetic field
the spinning electrons in some atoms pair up and create a magnetic field
Answer:
Explanation:
metal can become magnetic if they have many spinning electron. When the majority of atoms spin in the same direction the strong magnetic field is produced the direction of electron spin determine the direction of magnetic field
Does climate change tend to be more abrupt or gradual? Explain your response.
Answer:
Gradual**
Explanation:
This seems to be an opinion based question but i mean if you look back at history in the early ages or pre- industrialization the worls had very little pollution but gradually as factories cars and other things started being invented we as humans started releasing harmful substances into our atmosphere which began slowly craving away at the ozone layer and til date we are doing the same thing and are facing climate change/ global warming. The world did not suddenly face this problem.
I hope this makes sense
A mutation that hides the effect of another mutation at a site that is distinct from the site of the original mutation, but with in the same gene. This mutation is best described as a
Answer:
The correct answer is intragenic suppressor mutation.
Explanation:
A suppressor mutation partially or completely converses the effects of a different mutation. A suppressor mutation is of two kinds, that is, an intragenic suppressor and an intergenic suppressor. An intragenic suppressor converses the influence of a mutation at a distinct site in a similar gene.
On the other hand, an intergenic suppressor converses the influence of a mutation at a distinct locus of the gene. It is the intragenic suppressor mutation, which takes place in a similar gene where the occurrence of the first mutation had taken place. Therefore, the mutation, which hides the influence of another mutation at a location, which is different from the location of the original mutation, but taking place in a similar gene can be illustrated as the intragenic suppressor mutation.

Use the following scenario to answer the next following question(s):
You and your friends go to the beach for vacation. You all walk down to the beach to go swimming. When you get there, you see the water is murky and green, and there are algae blooms floating on top.
Reference: Ref 6-3
If it is excess nutrients which are feeding the algae blooms and lowering the oxygen content in the water, that process is called:
A. nutrient cycling.
B. nitrification.
C. eutrophication.
D. hypoxia.
Answer:
eutrophication
Explanation:
Eutrophication refers to a situation in which the aquatic environment becomes excessively enriched with nutrients. This leads to algal blooms in aquatic habitats such as lakes. These nutrients come from Fertilisers used in farming, which find their way into water bodies through run-off thereby increasing nutrient levels.
Excess nutrients causes phytoplankton to grow and reproduce at an alarming rate resulting in algal blooms. This bloom disrupts the balance in the ecosystem leading to many problems.
The algae may end up using all the oxygen in the water, causing oxygen shortage for aquatic life. Some of the algae may die, their decay may lead to further oxygen depletion. As oxygen is depleted, aquatic organisms may also begin to die.
What term matches the following definition: " ...a fundamental evolutionary process that results in both the adaptation of species to their environments and the generation of biodiversity (new species)"?
Answer:
a.Natural selection
b.Evolution
c.Artificial selection
d.Co-evolution
The correct option is A.
Natural selection.
Explanation:
The correct answer is natural selection because Natural selection is an evolutionary process which was discussed by Charles Darwin in 1859, In one of his theory that it is the ability of organisms to develop traits or characteristics that will help them to adapt and ensure their survival in their environment and then passing or transferring these new traits to new species or offsprings over generations through reproduction.
Knowledge of the driver mutations underlying cancer has led to targeted therapeutics, such as the protein kinase inhibitor imatinib (trade name Gleevec) in cases of chronic myeloid leukemia. Cancer cells often become resistant to a given drug, so researchers continue searching for new drugs that target proteins that contribute to the cancerous phenotype. One recent promising approach uses drugs that lead to ubiquitination and proteasomal degradation of the target protein. Which of the following mutated proteins are good candidates for this approach?
A) oncogenes
B) proteins with loss-of-function mutations
C) proteins with gain-of-function mutations
D) tumor suppressor genes
Answer:
C) proteins with gain-of-function mutations
Explanation:
Gain-of-function mutations: In biology, the term "gain-of-function mutation" is described as one of the different types of mutation in which the altered or changed "gene product" consists of an entirely new pattern or molecular function associated with gene expression. However, the "gene-of-function mutations" are being always considered as "Semidominant or Dominant".
In the question above, the correct answer is option C.

Which sentence about protist is accurate
Answer:
there are no sentences
Explanation:
_________ is (are) the product of Transcription, and the starting material of Translation. A. tRNA B. Amino Acids C. mRNA D. Ribosomes
Answer:
C. mRNA
Explanation:
Hello,
In this case, we may remember that when DNA is undergoing transcription a specific sequence is copied via the RNA polymerase in order to produce the messenger RNA which is subsequently used as the starting material of translation for the protein synthesis as shown on the attached picture. Thereby, answer is C. mRNA, since the transcription process produces it and then, for the translation process, it contains the codons which promote the formation of polypeptides (proteins) via the connection of the anti-codons contained in the tRNA which also provide the amino acids for the polypeptides formation.
