how does the concept of apoptosis relate to sally cancer cells compared with normal cells ?
Answers
Answer:
Apoptosis is defined as a programmed cell death and plays very important role in the removal of cancerous cells. Apoptosis is the process in which cell undergoes several processes and attempt sui-cide. Apoptosis do not cause any harm to human cells as it removes only unwanted cell.
Apoptosis can prevent cancerous cells by telling unwanted growth of cell to self destruct. Cancer cells are formed due to proliferation of cells and ignore the signals of self destruction to prevent apoptosis.
In Sally's case also, cancer cells ignored the signal of apoptosis and a tumor was found in her colon.

A yeast cell that forms a bud is called the "mother cell." Why is there no mother cell after a paramecium divides?
Answers
There is no mother cell after a paramecium divides because it is divided by binary fission and the paramecium is divided into two identical cells, called daughter cells, there is no mother cell left.
What is paramecium?Paramecium is a protist. It is oval-shaped with cilia all over the body, and it is minute and can be seen only under a microscope. It engulfs its food through the body cavity, which is its mouth.
Binary fission means when the cell is divided into two daughter cells. The division is asexual reproduction. The cell divided DNA into two copies and then each cell gets the DNA.
Thus, there is no mother cell after a paramecium divides since binary fission is used and the paramecium is split into two identical cells, known as daughter cells.

Someone please help I took the picture this is my last question on my homework
Answers
Answer:
According to the image that represents a cell in the human body, the true statement is that structure 4 is the cell membrane that provides exchange of O₂ & CO₂.
Explanation:
In cells, the cell membrane acts as a semi-permeable barrier to the passage of substances, including nutrients and oxygen (O₂).
One of the functions of the cell membrane is to allow the exchange of O₂ —necessary for the cell— and carbon dioxide (CO₂), a product of cell metabolism that must be removed.
In the image, the structure identified with the number 4 corresponds to a cell membrane of human cells that provides this gas exchange.
The other options are not correct because:
Structure 1 is a ribosome, not a chloroplast. Structure 2 is the nucleus, not a vacuole containing DNA. Structure 3 is a mitochondria, but protein synthesis does not occur there.5. How is this different from Darwin's idea of fitness?
Answers
Answer:
Darwinian fitness differs from the “physical fitness”, which is more associated with health, muscle tissues, oxygen, and physical effort. Darwinian fitness is more concerned about reproductive success. Darwinian fitness describes how successful an organism has been at passing on its genes.

Which statement is true about mutations?
W
A. Mutations are always beneficial.
В.
Mutations are always harmful in plants.
C.
Mutations only affect humans.
D.
Mutations can be caused by high-energy radiation.
Answers
Answer:D.
Mutations can be caused by high-energy radiation.
Explanation:
"Mutations can be caused by high-energy radiation". This statement is true. Therefore option D is correct.
Mutations are changes in the DNA sequence of an organism's genome. They can occur naturally as a result of errors during DNA replication or recombination, or they can be induced by various factors including radiation, chemicals, or environmental factors.
High-energy radiation, such as X-rays or ultraviolet (UV) radiation, has the potential to cause mutations in the DNA. This radiation carries sufficient energy to disrupt the normal structure and functioning of DNA molecules, leading to changes in the genetic code.
Exposure to high-energy radiation can result in different types of mutations, including point mutations (changes in a single nucleotide base), deletions, insertions, or rearrangements of DNA segments.
It is important to note that not all mutations are harmful or beneficial. Some mutations may have no significant effect, while others can be detrimental or even provide advantages in certain circumstances, such as adaptations to new environments or resistance to specific diseases.

When the Earth's continental crust and ocean crust formed, they were different densities. Why did they differ in density and how did this affect their formation?
A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
B.) The continental crust was thicker and more dense. It sunk below sea level, separating land from water.
C.) The continental crust was thinner and less dense. It rose above sea level, separating land from water.
D.) The continental crust was thinner and more dense. It sunk below sea level, separating land from water.
I think it’s B, but I’m not completely sure. Help please!
Answers
Answer: A.) The continental crust was thicker and less dense. It rose above sea level, separating land from water.
Explanation:
The Ocean crust is made out of rocks like basalt with a thickness of about four miles. The Continental crust on the other hand is made out of granite and other similar minerals and is between six and 47 miles in thickness which makes it thicker than the Oceanic crust.
With basalt being more dense than granite, the Oceanic crust sank and the Continental crust rose thereby separating land from water.

The following is the results of a genotype being "foiled" for a dihybrid cross: BS | Bs | bS | bs
Determine the parents genotype
A) BBSS
B) BBss
C) BbSs
D) BbSS
Answers
Answer:
C. BbSs
Explanation:
The foiled results of the genotype include both capital and lowercase versions of both letters, b and s.
This means the genotype has to be heterozygous for both the B and S traits, since the foiled results have both dominant and recessive alleles.
So, the genotype must be C, BbSs
The foiled results of the genotype for the offsprings include BS | Bs | bS | bs.
The parent's genotype will then be BbSs.
The genotype of both parents have to be heterozygous as a result of the
presence of its forms in the B and S traits. There is the presence of the
dominant (B,S) and recessive traits (bs).
The genotypes of the parent will however have both traits in them which
translates to the option C) BbSs being the most appropriate.
