While some mutations can benefit an organism, others are harmful and can lead to cancer. Which of the following best describes how mutations can cause cancer in an organism?
O Cell division becomes uncontrolled when mutations occur in genes that regulate cell division.
O Cells with mutations outnumber and consume normal cells that do not have mutations,
O A mutation can attack a cell's DNA and cause an autoimmune response in the cells.
+
O Mutations cause cells to become unable to divide and the cells die in masses, forming tumors.
Answer:
Cell division becomes uncontrolled when mutations occur in genes that regulate cell division.
Explanation:
Answer:
The answer is "A."
Explanation:
Cancer develops when the cells in the body are constantly dividing uncontrollably. In humans, cancer is often the result of a negative mutation genetically. The other answers are wrong and do not match the way cancer forms. So, A will be your answer.

Explain why it makes sense to use the word translation to describe protein synthesis and why it would not make sense to use the word translation to describe mRNA synthesis?
Answer:
The application of the word translation makes sense at the time of describing the synthesis of protein as the language of nucleic acids is transformed into the language of polypeptides by the phenomenon of translation. On the other hand, it will not be suitable to describe the synthesis of mRNA using the word translation as the nature of the biomolecule stays similar because both the DNA and the product of DNA, that is, mRNA are nucleic acids.
Areas of the Earth near the equator receive large amounts of solar energy. How does this lead to increased rainfall?
A.

The solar energy heats the air, which causes water vapor to condense.
D.
The solar energy provides the energy for water to evaporate.
Answer:
D
Explanation:

How did Watson and Crick learn about Chargoff's rules?
Answer:
Chargaff explained his findings and research to Watson and Crick at Cambridge.
Explanation:
Watson and Crick met Erwin Chargaff at Cambridge in 1952, where he explained his research and findings to them. His rule of parity, or 1:1 rule, stemmed from his discovery of guanine's equal ratio in pairing with cytosine.
Watson and Crick went in to use Chargaff's findings and the work of the researcher Rosalind Franklin as a basis for their work on DNA's double-helical structure.

Oxygen has 6 valence electrons. How many electrons does an atom of oxygen need to become stable?
two
four
six
eight
Answer:
2 electrons
Explanation:
According to the octet rule, atoms must bond to each other, sharing electrons among themselves in an attempt to complete their valence shell (last layer of the electrosphere). In other words, an atom becomes stable when it has 8 electrons in its valence shell.
Oxygen atoms have six electrons in their valence shell, so to achieve the stability suggested by the octet rule (eight electrons), these atoms share two electrons, forming one oxygen gas (O₂) molecule.
Answer:
A. two

( Need ASAP!!) Which of the following statements best demonstrates that gene expression is regulated?
F. Cells protect their DNA by enveloping it in a nucleus.
G. Cells do not transcribe all of their genes all of the time.
H. Each cell has an exact copy of all DNA.
3. Each tRNA has a specific amino acid that it carries.
Answer:
Explanation:
hi
Regulation of gene expression involves process by which a cell determines which genes, among the numerous genes in its genetic make-up, are "switched on" (expressed).
The option that demonstrate that gene expression is regulated is that Cells do not transcribe all of their genes all of the time.
In eukaryotes, regulation of gene expression can take place at various points. This might include post transcriptional and post-translational modifications. This mechanism ensures to control some various processes which include:
When a gene is expressed to produce RNA and protein,Amount of the protein is produced, And when the protein is no longer required.Learn more about gene expression: https://brainly.com/question/25703686

When a hawk eats a mouse and then uses the energy from the mouse to fly,
the hawk's body converts to what
Answer:
It would be Chemical to mechanical
Explanation:
Because food is a chemical source and the hawk flying is a mechanical source.
When a hawk eats a mouse and then uses the energy from the mouse to fly in this case chemical energy is converted to mechanical energy.
What is food chain?Food chain is the sequence of flow of energy in which all the levels get proper food supply and it is the food web which starts from producer and ending at top such as predator species, decomposer and detritivores.
In food chain plants play the role of producers as they are autotrophs and they prepare their own food in the presence of sunlight and all other organisms depend upon plant for food so they are known as producers in the food chain.
The main role of food chain is to understand the importance of each organisms and how they are depend on each other as well as to understand the role of food chain in maintaining ecological balance.
Therefore, When a hawk eats a mouse and then uses the energy from the mouse to fly in this case chemical energy is converted to mechanical energy.

B. Crossing over will result in new genetic material.
C. Chromatids will have just moved toward opposite poles.
D. One much larger cell will be produced through nuclear fusion.
Answer:
i think its b i could be wrong
Explanation:
The correct model shown is Crossing over will result in new genetic material.
What is crossing over?
When it comes to genetics and genomics, the term "crossing over" describes the DNA exchange that takes place between paired homologous chromosomes (one from each parent) during the development of egg and sperm cells.
This process leads to novel allele combinations in the gametes (egg or sperm) produced, ensuring genomic variety in any offspring born.
When chromosomes of the same type are paired together during meiosis, a biological event called crossing over takes place. Parts of the chromosome can be exchanged when two chromosomes, one from the mother and one from the father.
Therefore, The correct model shown is Crossing over will result in new genetic material.
