The electron transport chain (ETC) is the final step of cellular respiration and takes place in the mitochondrion.
The final step in cellular respiration is the electron transport chain. This is sometimes abbreviated as ETC. ETC needs oxygen, which means aerobic process. It occurs at the edges of the inner lining of mitochondria. These handles are called cristae.

A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.
What genetic explanation can you provide as to why the girl
suffers from hemophilia?
answer:
So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.
Explanation:
A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.

Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.
A microscopic image of staphylococcus aureus is shown.
Which immune system component initially results in the inflammation and responds quickly when Staphylococcus aureus enters the bloodstream?
complement system
phagocytes
Langerhans cells

Which parts of DNA provide the code for proteins?
Answer:
The genetic code is the sequence of nucleotide bases in nucleic acids (DNA and RNA) that code for amino acid chains in proteins. DNA consists of the four nucleotide bases: adenine (A), guanine (G), cytosine (C) and thymine (T). RNA contains the nucleotides adenine, guanine, cytosine and uracil (U).
A gene is a section of a DNA molecule that contains the information to code for one specific protein.
The DNA code contains instructions needed to make the proteins and molecules essential for growth, development and health.What is gene?A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. Many genes do not code for proteins.What is DNA?
DNA is the genetic material, which is involved in carrying the hereditary information, replication process, mutations, and also in the equal distribution of DNA during the cell division.

Determine the temperature of the bar on the fahrenheit scale.
Answer:
Determining bar temperature on Fahrenheit scale -
The temperature of the bar is given as 50 degrees Celsius.
If we know the temperature on the Celsius scale, we can convert it to the Fahrenheit scale.
We know
C / 5 = (F-32) / 9; Where C is the temperature on the Celsius scale and F is the temperature on the Fahrenheit scale.
Now,
50/5 = (F-32) / 9
Or, (F-32) / 9 = 10
Or, F-32 = 90
Or, F = 90 + 32
Or, F = 112 degrees Fahrenheit.
That is, the temperature of the bar on the Fahrenheit scale is 112 degrees Fahrenheit

Prokaryotic cells are single-celled microorganisms known to be earliest on earth.Eukaroyotic cell have a nucleus enclosed within the nuclear membrane and form large and complex organism.
Difference between unicellular and multicellular.
The main difference between unicellular organisms and multicellular organisms is that unicellular organism is unspecialised it means all the body function depends upon only on the single cell and in multicellular organism there is specific cells for specific purposes.
Multicellular and unicellular organisms are perform almost all the life running activities and processes such as respiration, reproduction digestion, breathing, and metabolism.
In unicellular organism division of labour is at the organ level on the other hand in multicellular the division of labour at cellular, tissue, organs and organ system level. Unicellular organism has simple body organization and multicellular organism have complex body organism.
Therefore,the best example that shows the levels of organization in a multicellular organism from the smallest level to the largest is cell, tissue, organ, organ system, organism. Thus, option B is correct.

How does the CF gene affects the cell membrane?
Answer:
Normal Function. The CFTR gene provides instructions for making a protein called the cystic fibrosis transmembrane conductance regulator. This protein functions as a channel across the membrane of cells that produce mucus, sweat, saliva, tears, and digestive enzymes.
Explanation:
Sickle cell anemia is carried on the recessive allele. Normal is dominant. Mary is a carrier for sickle cell and Mike is normal (but not a carrier).
A. What are the chances of Mary and Mike having a sickle cell child?
B. What are the chances of them having a child who is a carrier?
Answer:
A. 0
B. 1/2 or 50%
Explanation:
Let us assume that the sickle cell anemia trait is represented by s and the alternate normal version by S.
Mary, a carrier would have the genotype Ss.
Mike, a perfectly normal person would have the genotype SS.
If both Mary and Mike marry:
Ss x SS
offspring: SS SS Ss Ss
(A) In order to have sickle cell, the two alleles must be recessive. None of the offspring from the cross has two recessive alleles. Hence, the chances of Mary and Mike having a sickle cell child is zero.
(B) From the cross, two out of four of their potential offspring have the trait in heterozygous condition. Hence, the chances of Mike and Mary having a child who is a carrier is 1/2 or 50%.

Why did Mendel study pea plants?
They reproduce asexually and have one trait that is easy to observe.
They reproduce asexually and have many traits that are easy to observe.
They reproduce sexually and have one trait that is easy to observe.
They reproduce sexually and have many traits that are easy to observe.
Answer:
For Gregor Mendel, pea plants were fundamental in allowing him to understand the means by which traits are inherited between parent and offspring. He chose pea plants because they were easy to grow, could be bred rapidly, and had several observable characteristics, like petal color and pea color.
Explanation:
Gregor Mendel chose the pea plants for his experiments because the garden pea is an ideal subject in the study of genetics for the following reasons: The presence of observable traits with contrasting forms. It produces many offspring in one cross. Short life cycle.
Why did Mendel choose pea plants to study?Solution: Pea plants were chosen for Mendel's experiments because they are easy to grow, have a short life period, and produce larger flowers. Pea plants are also self-pollinated.
What was the purpose of the pea plant study?Gregor Mendel describes his experiments with peas showing that heredity is transmitted in discrete units. From the earliest time, people noticed the resemblance between parents and offspring, among animals and plants as well as in human families. Gregor Johann Mendel turned the study of heredity into a science.

During winter's freezing temperatures, some plants can remove water from their cells to reduce the amount of water that will freeze inside them. Why would plants need to do this
Answer:
The expansion of excess water as it turns to ice inside the cells would break the cells apart
Explanation:
We know that water expands anomalously. It expands between 4- 0°C.
Hence water expands upon freezing. Ice has more volume than liquid water and takes up more space in plant cells.
The expansion of excess water as it turns to ice inside the cells would break the cells apart
