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'
PAMP-DAMP complexes are key to understanding inflammatory disorders and cancer.

Choose a strategy to clone genes known only by a mutant phenotype in organisms with highly efficient transformation procedures and relatively small genomes.
Answer:
By combining traditional genetic mapping with whole-genome sequencing (next-generation sequencing)
Explanation:
Map-based cloning, also named positional cloning, is a technique used to identify genetic sequences linked to markers whose exact physical localization in the genome is known. Map-based cloning has shown to be useful to clone genes, however, this approach is limited to the existence of mutant phenotypes in different organisms/accessions/strains. In recent years, map-based cloning has been combined with next-generation sequencing methodologies in order to clone genes in background of single mutants without information on multiple organisms. This type of strategy has the potential for identifying causal mutations and thus clone genes in species with small genomes and high transformation efficiencies such as, for example, Arabidopsis thaliana.

Predict what will happen to the following lung volumes and capacities during strenuous exercise. Assume that you are comparing from a baseline of normal resting respiration.
Lung Volume or Capacity Predicted change from resting baseline : Use Increase, Decrease or No Change
TLC (total lung capacity)
No change
VC (Vital capacity)
IC (Inspiratory capacity)
FRC (Functional residual capacity
TV (Tidal volume)
IRV (Inspiratory reserve volume)
ERV (Expiratory reserve volume)
RV (Residual volume)
Answer:
During intense exercise:
lung capacity increases
vital capacity increases
respiratory capacity increases
functional residual capacity increases
tidal volume increases
the inspiratory and expiratory reserve volumes decrease as does the residual volume.
Explanation:
Residual volumes decrease because having better lung capacity, better development of the secondary skeletal muscles that collaborate in expiration and inspiration, these are given in a better way, and more effectively.
If these processes take place more efficiently, their potentiality increases and expiration and inspiration move a large current of air into the lungs, thus leaving less reserve airs.
Those people who have increased exhalation or inspiration reserve, have a weak activity of the musculature in the processes and function as "stagnant air" which is synonymous with a lack of physical activity or aerobic capacity.
It is important to clarify that all the above processes are accompanied by an increase in the size of the chest cage
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".

Explain what, if any, is the issue facing DNA polymerase in regards to its 5’->3’ activity when replicating DNA.
Answer:
The two strands of DNA are replicated in different ways
Explanation:
DNA replication is a process that occurs during the S phase of the cell cycle that consists of making two identical copies of the double-stranded DNA molecule, which subsequently are distributed in the daughter cells during cell division. During this process, DNA polymerase can add nucleotides in 5' to 3' direction, but not in 3' to 5' direction. In consequence, the DNA strand that has 3’ to 5’ directionality can be synthesized directly, while the DNA template strand that has 5’ to 3’ directionality can't be synthesized in a continuous manner and thereby it is created by adding small DNA fragments, which are known as Okazaki fragments (150-200 nucleotides in size).
The ion composition of perilymph is like that of interstitial fluid; high sodium and low potassium levels. If someone ruptured the vestibular membrane, the membrane between the vestibular duct (Scala vestibuli) and the cochlear duct (Scala media), what would be the effect of such a rupture on the concentration of potassium in the endolymph in the cochlear duct
Answer:
The concentration of potassium will decrease
Explanation:
The cochlear ducts are composed of two distict types of fluids: 1-perilymph, rich in sodium (140 mM) and low in potassium (5 mM), and 2- endolymph, rich in potassium (1 mM) and low in sodium (150 mM). The perilymph fluid has a similar composition to the rest of the extracellular fluids, while endolymph present a unique ion composition that is not found in other fluids of the body. It is believed that the cochlea can regulate potassium flow without using energy (i.e., without use ATP), since potassium enters into the cells through passive pathways, while this ion ion leaves the cells by an active mechanism.

fur color in mice is affected by a single gene the gene for fur color has two alleles: b that causes dark brown fur and b that causes light brown fur. What is or could be the genotyes of a mouse with dark brown fur
Answer:
(BB) or (Bb)
Explanation:
Given that (B) allele , is responsible for fur that is dark brown, and (b) allele is responsible for fur color that is light brown, the dominant allele is (B) allele for dark brown fur. Dark brown fur allele would always express itself over the recessive allele, (b).
For a mouse that has dark brown fur, the possible genotype it could have is either (BB) => 2 dominant allele, or (Bb) => 1 dominant allele and a recessive allele. The dominant allele would always express itself even in the presence of the recessive allele.

Acidification of the stomach uses all of the following types of transport EXCEPT: A. channels. B. pumps. C. antiporters. AND. symporters. E. All of these are used by parietal cells.
Answer: Option E.
All of these are used by parietal cells.
Explanation:
Parietal cells are found in the stomach and they produced gastric acid(Hcl)..
HCl is produced when water mixed with carbondioxide in the parietal cell to produced carbonic acid which is catalyses by carbonic anhydrase. The carbonic acid then dissociates into hydrogen ion and carbonate ion.
Parietal cell produce HCl due to histamine (via H2 receptors), acetylcholine (M3 receptors) and gastrin (gastrin receptors).
Therefore it uses channels, pumps, antiporter.

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.

In the quest to understand the basis of infertility in humans, researchers have identified a mutation in a gene associated with chiasmata. This protein normally acts to promote homologous recombination.Why might a defect in homologous recombination have consequences for fertility?A. The chiasmata halts the whole process of meiosis, if crossover do not form properly.B. Crossover formation is a necessary step in meiosis I to ensure proper chromosome segregationC. A checkpoint requires a certain level of genetic variability for meiosis to proceed.D. Chiasmata are the connections between the centromeres and the centromeres that pull them to each pole of the daughter cells.
Answer:
B. Crossover formation is a necessary step in meiosis I to ensure proper chromosome segregation
Explanation:
Crossing-over is a unique phenomenon that occurs in the prophase I stage of meiosis I, where non-sister chromatids of homologous chromosomes exchange their chromosomal segment. The physical point where this exchange occurs is called CHIASMATA. Hence, a mutation that affects the gene associated with the chiasmata will affect the occurrence of crossing over or homologous recombination.
Crossing-over, through the formation of the chiasmata, is responsible for the physical alignment and proper segregation of chromosomes into gametes. Naturally, the chiasmata formed as a result of recombination during meiosis helps ensure that the chromosomes stay together until it is the right time to separate. This way, any chromosomal defect in the resulting gamete is prevented.
However, an error or defect in homologous recombination might give rise to gametes with chromosomal disorder, a condition known as ANEUPLOIDY i.e. missing or additional chromosomes in gametes. This can affect the fertility of the involved human.
Which of the following best describes how crossing over occurs during meiosis?
