Autopsy conducted on an individual who had died of pneumonia revealed bluish-green pus filling the lung. The causative agent of pneumonia was most likely to be
Proteus vulgaris
Escherichia coli
Salmonella typhi
Pseudomonas aeruginosa
Staphylococcus aureus
Answer:
The agent causing the pneumonia, where bluish-green pus was found, is most likely Pseudomonas aeruginosa.
Explanation:
Pseudomona aeuriginosa is a gram-negative bacteria that is one of the main causes of hospital-acquired infections, including pneumonias in mechanically ventilated patients.
One of the characteristics of P. aeuriginosa is the formation of a bluish-green pus, since it has the capacity to form cyanide-based blue pigment upon contact with the organic tissues it infects. This is the reason why previously P. aeruginosa was called a pyocyanic bacillus.
The other options are not correct because the only bacterium that produces blue-green pus is P. aeruginosa.

A group of students wants to build a ramp to move boxes from the floor up to a stage. How can the students reduce the amount of effort needed to push the boxes up the ramp?
Question 8 options:
by making the ramp as long as possible
by making the ramp’s height and length equal
by building the ramp out of a lightweight material
by covering the ramp’s surface with a soft rubber mat
If students wants to reduce the amount of effort needed to push the boxes up the ramp, it is possible by making the ramp’s height and length equal, hence option 2 is correct.
Why does it take more force to move a heavy box up a ramp?If students moves a heavy box up a ramp, there is so much friction on the undersurface of the box when going up a ramp.
To reduce the amount of effort needed to push the boxes up the ramp by making the ramp’s height and length equal, in second option by making the ramp as long as possible needs more effort.
In the fourth option, by covering the ramp’s surface with a soft rubber mat, make it harder to slide up boxes.
Therefore, by making the ramp’s height and length equal, it is easier to reduce the amount of effort.

A corn field is divided into four parts each part is ‘treated’ with a different fertilizer to see which produces the most corn. What is the dependent variable?
1. Different Fertilizers
2. Corn Production
Answer:
The correct answer is - 2. corn production.
Explanation:
The dependent variable of a scientific investigation is a variable that depends on the independent variable. It is a variable that is required to check or find the effect of the independent variable and also known as output value that helps to know the effect of input values or independent variable.
In this case, the input value or the independent variable is different fertilizer as it is the only variable that is manipulated by the researcher, and due to this manipulation, the production of the corn affected which is the dependent variable as it depends on the independent variable.

Assign characters to the readers in your group.
Find a section in the novel with lots of good dialogue.
Find a section in the novel with lots of sensory details.
Assign lines and sentences to readers in your group.
Answer:
Find a section in the novel with lots of good dialogue.
Explanation:
Firstly, you can't assign characters or lines to the readers in your group for the first step. You need to search for a section that has good information to start it off with. Then, you can proceed to assigning whatever you like.
1. Assign characters to the readers in your group. THIS SHOULD BE THIRD since you've have already found some good dialogue and details on what to do. With that being said, it's now necessary to assign your characters. #3
2. Find a section in the novel with lots of good dialogue. THIS SHOULD BE FIRST as you need to start off with finding some good dialogue and descriptions as your "base".
#1
3. Find a section in the novel with lots of sensory details. THIS SHOULD BE SECOND as you need to find good dialogue in order to even find sensory details. Good dialogue will contain plenty of sensory details.
#2
4. Assign lines and sentences to readers in your group. THIS SHOULD BE FOURTH since you need characters to even assign lines and sentences in the first place.

what is mutation? why are mutations more serious when they occur in a sex cell?
Answer:
A mutation is the changing of the structure of a gene, resulting in a variant form that may be transmitted to subsequent generations, caused by the alteration of single base units in DNA, or the deletion, insertion, or rearrangement of larger sections of genes or chromosomes. Mutations in sex cells are more serious because they are heritable and affect the next generation.
Explanation:
If a cell suddenly stopped producing transfer RNA, which of the following processes would be immediately affected?
A) MUTATION
B) REPLACATION
C) TRANSCRIPTION
D)TRANSLATION
Answer:
D
Explanation:
If a cell suddenly stopped producing transfer RNA, the process that would be immediately affected is translation. The correct option is D.
What is translation?The translation is the second step of the process of protein synthesis. In translation, the RNA give instruction to the ribosomes, and they produce protein.
The first step in protein synthesis is transcription, in which the DNA gives its template to produce RNA. The RNA then in translation produces protein. The translation is divided into three steps. They are initiation, elongation, and termination.
Initiation starts the process and elongation runs the process. The termination gives the stop codons to stop the process. The codons are the codes of genetic codes.
Thus, the correct option is D. translation.

The prokaryotic genome, on the other hand, lacks a membrane-bound nucleus. The major organization or content between these two genomes are:
- Prokaryotic genomes generally have less DNA and fewer genes than eukaryotic genomes.
- Prokaryotic genomes have fewer repeated sequences and noncoding, intragenic sequences than eukaryotic genomes.
- Most prokaryotic genomes are contained in one circular chromosome while most eukaryotic genomes are contained on several linear chromosomes.
- In general, eukaryotic genomes contain many introns, repeated sequences, and transposable elements.

Answer:
D. 3H2O
Explanation:
An atom is the smallest unit of matter that has the characteristics of a chemical element. It consists of protons, neutrons, and electrons - small electrically charged particles.
They make up molecules - electrically neutral groups of two or more atoms connected by chemical bonds. Multiple molecules that consist of two or more different atoms make up a chemical compound.
The chemical compound that has nine atoms is 3H2O. Here, we have three molecules of water. Each molecule consists of three atoms - two hydrogen atoms and one oxygen atom. This means that three of these molecules have a total of nine atoms.

In your own words, explain why an organism would require all four of the main biomolecules. What would occur if any of these biomolecules were missing? Are any of the biomolecules more important than the others? Is there one that we could live without?
Answer:
An organism requires all four main biomolecules because each provides a specific and necessary function for the organism. None of the biomolecules is more important than another, and if any of them were missing, life would not be possible.
Explanation:
The main biomolecules of living beings are carbohydrates, proteins, lipids and nucleic acids, each with a specific function and necessary for the development of life.
The presence of these four biomolecules is necessary because each one fulfills specific and irreplaceable functions, such as:
Carbohydrates: are the main source of energy, forming part of organic biomolecules such as glycolipids, glycoproteins or sugars that form the structure of nucleic acids.Proteins: important for their structural function and for molecules such as enzymes, which contribute to organic functions. They are also part of the cell membranes.Lipids: are the molecules that predominantly form the cell membranes. Additionally, they form functional molecules, such as hormones, and are a reserve energy source.Nucleic acids: DNA and RNA are not only necessary for organic biosynthesis, but also determine the structure and function of each organism. The reproductive and perpetuation function of the species is based on the transfer of genetic material contained in the DNA to the offspring.What would occur if any of these biomolecules were missing?If one of the main biomolecules were missing, the function it provides could not be supplied by another, which would imply the non-viability of a living being. If carbohydrates are missing there is no source of energy, without proteins there would be no tissues like muscle and no enzymes to facilitate organic reactions and without lipids there would be no cells. The absence of nucleic acids, per se, would determine the impossibility of all organic processes.
Are any of the biomolecules more important than the others?No one biomolecule is more important than another. Each one of them fulfills a specific and necessary function that cannot be supplied by another biomolecule.
Is there one that we could live without?All organic molecules are necessary, fulfilling an important function. The lack of any biomolecule in the organism is incompatible with life.
An organism requires all four of the main biomolecules because they're all important for the effective functioning of the organism.
It should be noted that the main biomolecules include protein, lipid, carbohydrates, and nucleic acids. They all play a vital role in how an organism functions.
If any of these biomolecules were missing, the function that can be provided by the biomolecule can't be provided by another biomolecule since they all play different roles. Also, there's no biomolecule that's important than another.

5. Knowing that acid rain has a pH of 2-3, would you conclude that crop species with a narrow soil pH range are in trouble? Is acid rain a problem for plant species and crops?
Answer:
Yes
Explanation:
Unless the crops acidity range is that of the rain( which it wouldn't be) it would throw off the crops Ph balance and harm it.
Yes, crop species with a narrow soil pH range are potentially in trouble due to acid rain. Acid rain can have harmful effects on plant growth and productivity. The acidity of the rain can change the pH level of the soil, making it more acidic and less hospitable for plants.
What is acid rain?Acid rain is a type of rain or other precipitation that is unusually acidic and has elevated levels of hydrogen ions (low pH). It is caused by the release of sulfur dioxide (SO2) and nitrogen oxides (NOx) into the atmosphere, which then reacts with water vapor to form sulfuric acid and nitric acid.
These acids can fall back to the ground as acid rain or other forms of precipitation and can cause harm to plants, animals, and infrastructure. Acid rain can also contribute to soil and water pollution and can have negative impacts on human health.
Acidic soil can also release toxic substances, such as aluminum, which can further damage plant roots and reduce plant growth. In addition, acid rain can damage plant foliage directly, leading to reduced photosynthesis and reduced yields.
So, acid rain can be a significant problem for plant species and crops, particularly those with a narrow soil pH range.
