Immediately after a client's thoracentesis on the right side of the chest cavity, the LPN/LVN notices a progressive swelling on the right side of the client's chest and neck. The LPN/LVN identifies which of the following conditions as the MOST likely cause of this swelling?1. Pneumothorax post-thoracentesis.2. Subcutaneous emphysema.3. Lipoma.4. Hematoma formation.

Answers

Answer 1

Answer:

2. Subcutaneous emphysema

Explanation:

Subcutaneous emphysema is a Medical condition where a bulging or swelling occurs beneath the skin due to passage of air or gas in the subcutaneous layer of the skin. Thoracentesis which is mostly done to remove fluid could cause air passage into the subcutaineous tissue resulting in swelling which progresses as more air enters the tissue

B. The bacteriophage used in the experiments was a T2 phage.
C. It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment.
D. Each scientist had his own method for labeling phage, so each conducted the same experiment using a different isotope.

Answers

Answer:

C. It was necessary that each of the two phage components, DNA and protein, be identifiable upon recovery at the end of the experiment.

Explanation:

Alfred Hershey and Martha Chase performed an experiment to identify the chemical nature of the genetic material.

After completion of the experiment, they found that DNA is a genetic material and not protein.

In this experiment, bacteriophage was used that is made up of DNA and protein so it was necessary to identify protein as well as DNA so both were labeled separately.

You discover a new sunflower that has blue flowers instead of yellow. When you cross this blue variety with a common yellow variety you get blue and yellow speckled flowers. What type of inheritance pattern does this gene exhibit?a. incomplete dominance. b. codominance.
c. simple Mendelian inheritance.
d. either incomplete dominance or codominance.
e. sex-influenced dominance.

Answers

Answer:

The correct answer is: B) codominance.

Explanation:

Codominance is a type of inheritance pattern that describes the relationship of two variations of the same gene: this means that in an individual, its two alleles manifest in the phenotype.

If a sunflower has both blue AND yellow speckles, it means that the two possible alleles are in a relationship, which makes these alleles CODOMINANT.

_______consists of energy-releasing decomposition reactions. Such reactions break covalent bonds, produce smaller molecules from larger ones, and release energy that can be used for other physiological work. Energy releasing reactions are called exergonic reaction.

Answers

Answer:

The correct answer is: Catabolism.

Explanation:

  • Catabolism can be defined as the metabolic process by which larger polymeric bio-molecules are broken down to smaller monomeric bio-molecules.
  • This process causes the breakage of the chemical bonds which link the monomeric units in the polymeric bio-molecule.
  • Large amounts of energy remain stored in these chemical bonds.
  • When these bonds break they release a huge amount of energy.
  • This released energy is then stored in the cells in the phospho-anhydride  bonds of the ATP or Adenosine Triphosphate molecules.
  • The monomers formed are either further broken down into simpler compounds to release more energy or are used for the synthesis of new polymers by the process of Anabolism.
  • In the catabolic process, polysaccharides are broken down in monosaccharides, polypeptides are broken down into amino acids and lipid molecules are broken down in fatty acids.

Which regions of the vascular bed is the actual site of gas exchange with surrounding tissue?

Answers

Capillaries

Explanation:

  • Capillaries are thin cells and help to gas exchange with surrounding tissue.
  • They are little to such an extent that red platelets need to course through them a single record. In the event that all the Capillaries in the human body were arranged in a single record, the line would extend more than 100,000 miles.
  • Encompassing this layer of cells is something many refer to as the cellar film, a layer of protein encompassing the narrow. Carbon dioxide (from deoxygenated blood) thus spills out of the Capillaries once more into alveoli to be breathed out into the earth.
  • Hence, the "capillaries" is the right answer.

Gas Exchange Process in Body

Explanation:

  1. The convey of oxygen from the lungs to the circulatory system, and elimination of carbon dioxide  from the circulation system to the lungs.it is known as gas exchange process.
  2. The lungs between the alveoli and a system of little veins called vessels, which are situated in the dividers of the alveoli.  
  3. The essential capacity of the lungs including the exchange of oxygen from breathed in air into the blood and the exchange of carbon dioxide from the blood into the breathed out air.  
  4. Gas exchange is significant on the grounds that it gives oxygen to the cells of living life forms with the goal that they can get vitality from natural atoms.  Three principle factors that influence gas exchange in the two animals  and plants:  
  • Surface territory of the film.
  • The bigger the surface region of the layer the higher the pace of gas exchange that happens.
  • Fixation inclination.  
  • Thickness of the film.

Many biofilm-specific phenotypes are controlled by "quorum sensing." This system allows bacteria to regulate gene expression according to the concentration of in its immediate environment.a) trueb) false

Answers

Answer:

True

Explanation:

this has been seen as an evolutionary step in bacteria activity. it also allows them to control the activity of the the whole community

Answer: A) True

Quorum sensing is the system that allows bacteria to regulate gene expression according to the concentration of in its immediate environment.

Explanation: Quorum sensing is the process by which bacteria cells communicate among/within themselves and share information about their density and as well adjust their gene expression accordingly.

In quorum sensing ,there is production, detection and response of bacteria cells to Autoinducers (extracellular signalling molecules).

Increase in bacterial population density brings about the accumulation of autoinducers in the environment,the bacteria cell now monitors the information of the autoinducers inorder to track changes in their cell number and collectively alter their gene expression.

Quorum sensing controls the disease causing ability of a bacterial cell.

Two-component regulatory systems rely on a balance of phosphorylation and dephosphorylation of sensor kinases and response regulators. If the response regulator became permanently phosphorylated due to lack of phosphatase activity, which of the following would NOT happen? Hints O The cell would become more sensitive to the environmental stimulus The cell would become insensitive to the environmental stimulus. The cell would not be able to "reset" its response cycle. O The operon controlled by the response regulator would be always transcribed or never transcribed, depending upon the regulatory role of the response regulator.

Answers

Answer:

The correct answer is the first statement.

Explanation:

A fundamental stimulus-response coupling mechanism that helps various species to react and sense different modifications taking place in various distinct environmental circumstances is known as a two-component regulatory system. Though this system is found in almost all the domains of life, however, it is generally witnessed in species like bacteria, mainly in the Gram-negative and cyanobacteria.  

In case, if the response regulator turns completely phosphorylated because of the absence of phosphatase activity, the cell would become insensitive towards the environmental stimulus. This generally happens as the cell will lose its tendency to sustain the response cycle because of the imbalance in the dephosphorylation and phosphorylation system that helps in sustaining the response of the cell towards a specific environmental stimulus.

The inner membranes of both mitochondria and chloroplasts are folded into various arrangements. What is the advantage of having a folded membrane rather than a simple interior membrane that follows the same oval shape as the exterior membrane?

Answers

The question is incomplete as itt does not have the options which are:

A) The folds in the membranes are a physical barrier for compounds that attempt to enter the organelle.

B) The folds allow for more surface area for the chemical reactions that occur across the inner membranes.

C) The folds allow these organelles to interact more efficiently with Golgi bodies.

D) The folds cause a necessary change in the organelles' internal pH.

Answer:

B) The folds allow for more surface area for the chemical reactions that occur across the inner membranes.

Explanation:

The mitochondria and chloroplast are double-membrane organelle that contains the outer and inner layer.

The outer layer is usually smooth of both the chloroplast and mitochondria but the inner membrane is not regular but folded.

The folding is an adaptive feature of these organelle to increase the surface area. The increased surface area allows the more ATPase in the inner membrane, therefore, increases the amount of ATP generated.

Thus, Option-B is correct.

Answer: Increased surface area.

Explanation:

The inner membrane of the chloroplast and mitochondria is folded because they provide maximum surface area for the processes takes place in the organelles.

The mitochondria helps in energy production by converting the glucose in adenosine triphosphate.

The chloroplast helps in providing maximum surface area for the process of photosynthesis.

The main advantage is the surface area which helps the organelle perform its function more efficiently.

Suppose two plant populations exchange pollen and seeds. In one population, individuals of genotype AA are most common (9,000 AA, 900 Aa, 100 aa), while the opposite is true in the other population (100 AA, 900 Aa, 9,000 aa). If neither allele has a selective advantage, what will happen over time to the allele and genotype frequencies of these populations?

Answers

Answer:

selection is not important at this locus; furthermore, the populations are no small, and hence the effects of genetic drift should not be pronounced, gene flow is occurring via the movement of pollen and seeds, thus, allele and genotype frequencies in these populations should become more similar over time, with regards to this locus, as a result of gene flow.

Answer is option "c"

Explanation:

  • Earth is the main planet in the solar system with a climate that can continue life. The cover of gases contains the air that we inhale as well as shields us from the impacts of warmth and radiation exuding from the sun. It warms the planet by day and cools it around evening time.  
  • Earth can bolster a wide assortment of living creatures in view of its different territorial atmospheres, which run from the outrageous cold at the posts to tropical warmth at the Equator. The local atmosphere is regularly portrayed as the normal climate in a spot over 30 years. A district's atmosphere is frequently portrayed, for instance, as bright, breezy, dry, or damp. These can likewise portray the climate in a specific spot, yet while the climate can change in only a couple of hours, the atmosphere changes over a more drawn out range of time.  
  • Earth's worldwide atmosphere is normal of territorial atmospheres. The worldwide atmosphere has cooled and warmed since the beginning. Today, we are seeing strangely fast warming. The logical accord is that ozone harming substances, which are expanding a result of human exercises, are catching heat in the atmosphere.
  • Hence, the right answer is option c " reduces the temperature extremes between day and night recycles."

Answer:

Explanation:

Salts and sugars work to preserve foods by creating A) lower osmotic pressure. B) hypotonic environment.
C) lower pH.
D) hypertonic environment.
E) depletion of nutrients.

Answers

Answer:

D) hypertonic environment

Explanation:

A hypertonic environment consists of a solution in which amount of solute outside the cell is more than the amount inside the cell. When the concentration of solutes is greater on the outside of a cell, water would move from inside the cell to outside of the cell, where the concentration is lower, hence causing shrinking of the cell.

Salt and sugar create a hypertonic environment in foods, thereby making the cells of food spoilage organisms to shrink and unable to thrive in the environment.
