A given mass of oxygen at room temperature occupies a volume of 500. 0 ml at 1. 50 atm pressure. what pressure must be applied to compress the gas to a volume of only 150. 0 ml?
5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.
GivenMass of oxygen at room temperature =500.0 ml
Volume of pressure = 50 atm pressure.
The gas to a volume = 150.0 ml
ExplanationThe volume decreases by the factor = 500.0 mL / 150.0 mL
= 10 / 3
The pressure of the gas increased by a factor of 10/3 , which would make its final value equal to
[tex]P_{final} = \frac{10}{3} * 1.50 atm[/tex]
= 5.00 atm
So, 5 atm pressure must be applied to compress the gas to a volume of only 150.0 ml.

If you sorted 200 flies by eye color and body color, how many whole flies out of that 200 would you expect to exhibit each of the four phenotypes?
9:3:3:1 is the ratio.
From the given data,
We have a 9.8 two, ratio since we have 49/5, 15/5, 18/5, and 5/5.
This ratio resembles nine a little bit, which is what we inferred from the opposition's score.
When the two relevant genes exhibit independent assortment, this is the result. Therefore, the chromosomes/genes are not connected.
We are finally getting a ratio of 9:3:3:1
In flies, two possible outcomes for the body color phenotype is black and brown.
Whereas in eye color we have white eye and red eye.
Here, white eye is recessive and red eye is dominant
What does the independent assortment law entail? According to Mendel's law of independent assortment, the alleles of two or more distinct genes are independently selected into gametes. In other words, an allele for one gene does not affect the allele for another gene that a gamete acquires.Where can I find independent assortment?Meiosis I of gamete production, when homologous pairs line up in random orientations at the center of the cell as they prepare to split, provides the physical foundation for the law of independent assortment.

The unique chemical structure of the cell wall of mycobacterium spp. is associated with the presence of:______.
The unique chemical structure of the cell wall of mycobacterium spp. is associated with the presence of N-glycolyl muramic acid and an increase in lipid content.
Mycobacteria have strong, four-layered cell walls that are exceedingly thick. Peptidoglycan makes up the first layer, whereas lipids make up the subsequent layers. In order to maintain appropriate osmotic stability, peptidoglycan performs crucial activities like stiffness and rigidity. Bacteria are resistant to environments that are acidic and alkaline due to the presence of lipids.
All Mycobacterium species can be identified by their thicker cell walls, which are waxy, hydrophobic and abundant in mycolic acids. This is a characteristic that sets them apart from many other bacterial species. The mycolic acids make the mycobacterium less prone to antibiotics. Additionally, these molecules aid the bacteria in tricking the immune system and then hiding from it.

What is Reproductive Isolation?The reproductive isolation mechanisms are a set of evolutionary mechanisms, behavioral, and physiological processes that are essential for speciation.
They either prohibit individuals of other species from having children or guarantee that any children are infertile. When individuals or groups diverge in the time of various behaviors, such as foraging or mating, reproductive isolation can arise.
Toad species Bufo americanus and Bufo fowleri exhibit reproductive isolation due to changes in mating season. Members of these species can successfully cross in the lab, resulting in healthy, viable hybrids.

What are the chemical changes that occur in your blood that will potentially stimulate an increase in ventilation during and shortly after exercise?
More CO2 and H+ is generated, enhancing oxygen unloading in the muscles in the process.
When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide. To cope with this extra demand, your breathing has to increase from about 15 times a minute when you are resting, up to about 40–60 times a minute during exercise.

In the DNA isolation process, ice cold 95% ethanol is used to break down the protein complexes and allow the DNA molecules to easily precipitate.
What is separation and isolation of DNA fragments?
The cutting of DNA by restriction endonucleases results in the fragments of DNA. These fragments can be separated by a technique known as gel electrophoresis.Since, DNA fragments are negatively charged molecules they can be separated by forcing them to move towards the anode under an electric field through a medium/matrix.The most commonly used matrix is agarose which is a natural polymer extracted from sea weeds.The DNA fragments separate (resolve) according to their size through sieving effect provided by the agarose gel. Hence, the smaller the fragment size, the farther it moves.The separated DNA fragments can be visualised only after staining the DNA with a compound known as ethidium bromide followed by exposure to UV radiation (you cannot see pure DNA fragments in the visible light and without staining). We can see bright orange coloured bands of DNA in a ethidium bromide stained gel exposed to UV light.The separated bands of DNA are cut out from the agarose gel and extracted from the gel piece. This step is known as elution.The DNA fragments purified in this way are used in constructing recombinant DNA by joining them with cloning vectors.To learn more about DNA isolation process: brainly.com/question/18316109
