1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.
The corn crop in an area is prone to infestation by larvae from moths that feed on the cornstalks and ears of corn. The techniques used by two farmers to protect the corn crop are described below.
Technique A: Sprayed his corn crop with an insecticide. The insecticide is known to kill all honeybee, butterfly, and moth larvae.
Technique B: Used a genetically modified variety of corn. The plant produces an insecticide which selectively kills only the moth larvae as it feeds on the corn.
Which technique is likely to have less of an impact on the environment?
Technique B because it may help humans who consume corn to fight bacteria
Technique A because it kills a broader variety of insects to protect the corn
Technique B because it preserves the harmless insects and targets only the moth larvae
Technique A because insecticide use is better for preserving the environment.

Explanation:
I hope this helps
Have a blessed day
The statement which is true for a radioactive isotope is " they break down quicker than stable isotopes because they are unstable and undergo decay.
What is radioactive isotope?A radioactive isotope is an isotope of an element which is under exposure to a radiation undergoes decay and breaks into lighter isotopes.
Radioactive isotopes are generally heavier and are unstable with short life time. They undergo radioactive decay by alpha/beta or gamma radiation to form stable lighter or smaller isotopes.
Therefore, option C that is, they break down quicker than stable isotopes is correct.

Defining Emotional Appeal
An emotional appeal is used to sway the emotions of an audience to make them support the speaker’s argument.
LEARNING OBJECTIVES
Break down the components that make up an emotional appeal
KEY TAKEAWAYS
Key Points
Pathos represents an appeal to the emotions of an audience.
An emotional appeal uses the manipulation of the emotions rather than valid logic to win an argument.
Emotional appeal is a logical fallacy, whereby a debater attempts to win an argument by trying to get an emotional reaction from the opponent and audience.
In debating terms, emotional appeals are often effective as a rhetorical device, but are generally considered naive or dishonest as a logical argument, since they often appeal to the prejudices of listeners rather than offer a sober assessment of a situation.
Key Terms
logical fallacy: A fallacy; a clearly defined error in reasoning used to support or refute an argument, excluding simple unintended mistakes.
Emotional Appeal Defined
Pathos represents an appeal to the audience’s emotions. Pathos is a communication technique used most often in rhetoric (where it is considered one of the three modes of persuasion, alongside ethos and logos), and in literature, film, and other narrative art.
Emotional appeal can be accomplished in a multitude of ways:
By a metaphor or storytelling, common as a hook
By a general passion in the delivery
By an overall emotion
By the sympathies of the speech or writing as determined by the audience
The pathos of a speech or writing is only ultimately determined by the audience.
The Purpose of an Emotional Appeal
An emotional appeal is directed to sway an audience member’s emotions and uses the manipulation of the recipient’s emotions rather than valid logic to win an argument. An emotional appeal uses emotions as the basis of an argument’s position without factual evidence that logically supports the major ideas endorsed by the presenter. In an emotional appeal, persuasive language is used to develop the foundation of an appeal to emotion-based arguments instead of facts. Therefore, the validity of the premises that establish such an argument does not prove to be verifiable.

Emotional Appeal: A picture like this could be used as an emotional appeal for a charity campaign to increase funding for soldiers’ families.
Emotional appeal is a logical fallacy, whereby a debater attempts to win an argument by trying to get an emotional reaction from the opponent and audience. It is generally characterized by the use of loaded language and concepts (God, country, and apple pie being good concepts; drugs and crime being bad ones). In debating terms, emotional appeals are often effective as a rhetorical device, but are generally considered naive or dishonest as a logical argument, since they often appeal to the prejudices of listeners

What is Acid ?
please don't report , don't give link and give the correct answer .
Answer:
An acid is a molecule or ion capable of donating a proton, or, alternatively, capable of forming a covalent bond with an electron pair. The first category of acids are the proton donors, or Brønsted–Lowry acids.
Answer:
Below in Bold
✧ \( \underline{ \underline{ \red{ \large{ \tt{E \: X \: P \: L \: A \: N \: A \: T \: I \: O \: N}}}} }: \)
♨ The word ' acid ' is derived from the Latin word ' acidus ' which means sour. An acid is defined as the substance which gives hydrogen ions or protons ( H+ ) when dissolved in water. For example :
Hydrochloric acid Sulphuric acid Nitric acid Carbonic acid Acetic acid✎ \( \underline{ \underline{ \purple{ \large{ \tt{Extra \: Info}}}}} : \)
☃ Physical properties :
Acids have a sour taste. But some acids like steric acid, boric acid , salisylic acid do not have a sour taste. Laboratory acids are more corrosive , so they are dangerous to taste.Acid turn blue colour of litmus paper into red and light yellow methyl orange into red. They make phenolphthalein colourless.☂ Chemical properties :
Acids have a high dissolving power and dissolve many substances. Some metals like zinc and magnesium react with acids like dilute sulphuric acid and dilute hydrochloric acid to produce salt and hydrogen gas.Acid react with base to give salt and water.Acid gives H+ ions when dissolved in water.Acid react with metallic carbonates to produce carbon dioxide.☼ Hope I helped! ♡

According to the (second) law of thermodynamics, the thermal energy of a system changes when work is done on the system. The thermal energy of a material (increases) when the temperature of the material increases. ... At the same temperature, 1 kg of water has (the same amount) of thermal energy as 2 kg of water.
explain the difference between the 3 types of galaxies
elliptical galaxies
spiral galaxies
barred spiral galaxies
There is quite a big difference between a barred spiral galaxy and an elliptical galaxy.
The image attached below shows a barred spiral galaxy, NGC 2217. In barred spiral galaxy there is large bar like structure across the core of the galaxy , and on the terminal end there are the spiral arms of the galaxy. It is believed that the bar plays a role of material transportation to the core. The bar funnels in the surrounding material toward the SMBH at the core. The arms of the barred spiral galaxy often host high star formation rate as seen in the image below. The bar is often consist of dust and old stars.Where as in elliptical galaxy, the galaxies are somewhat diffused and also they don’t host much of the new stars. Elliptical galaxies are often unbounded. Elliptical galaxies are believed to be formed from several mergers and that’t the reason for their inability to form new stars.

Why are some incomplete fossils able to be pieced together? Full fossils of large animals can be found together. Hard tissue, like bone, never breaks or chips. Fossils require salt water to be preserved fully. Impressions from the skin can be preserved.
Answer:
Explanation:
The fossil record is considered to be incomplete because fossilization is a very rare phenomenon. Most organisms decompose quickly after their death, and their remains dispersed.
