Answer:
it's An uncharged object.
if its not charged the electrically wont go on it
Explanation:
The statement that will correct the error in Edwin's notes is as follows:
An electrically charged object needs to touch an uncharged object before they attract or repel.Thus, the correct option is A.
How do electrically charged objects produce attraction?The electrically charged objects produce attraction of oppositely charged objects. For example, if a positively charged object and a negatively charged object bring close to each other, they interact with one another. Their forces act in the same direction. i.e. from the positive to the negative charge.
There is an interaction between two oppositely charged objects required in order to furnish attraction, while there is an interaction between two identical charged objects required in order to furnish repulsion.
Whether it is attraction or repulsion, it must be required that an electrically charged object needs to touch an uncharged object.
Therefore, the correct option for this question is A.

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.

B.replication → cell division I → cell division II
C.mitosis → cell division I → translation
D.cell division I → cell division II → transcription
Answer:
part c
Explanation:
The sequence replication → cell division I → cell division II describes the formation of gametes.
Where does the formation of gametes occur?Meiosis (reduced division), in which a germ cell splits into two pieces and produces four gametes, is the process by which gametes are created.
Meiosis is a type of cell division that results in the production of four gamete cells and a 50% reduction in the number of chromosomes in the parent cell.
The gonads are where gametes (germ cells) are made. This process is known as spermatogenesis in males and oogenesis in females. The majority of novel mutations arise during gametogenesis, however males exhibit a higher mutation rate.

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.

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.

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.
