In a study of a muscle disorder, several families exhibited vision problems, muscle weakness, and deafness. Analysis of the mtDNA (mitochondrial DNA) from affected persons in these families was analyzed using PCR (polymerase chain reaction) and gel electrophoresis. The unaffected samples were collected from multiple mitochondria, whereas each affected sample was collected from a single mitochondrion. What can you conclude about the affected individuals' mitochondrial DNA?
A. There is no common deletion.
B. There is one common deletion.
C. There are two common deletions.
D. There are more than two common deletions.
Answer:
A. There is no common deletion.
Explanation:
The correct answer to the given question is the option A. There is no common deletion.
In the study of the muscle disorder, the samples taken and the effects observed concludes that there was no common deletion among the analysed families and their mitochondrial DNA.

The smallest units of life are called
is the process of creating new living things.
is the phenomenon of living things responding to their environment
Answer:
1. CELL
2. REPRODUCTION
3. IRRITABILITY
Explanation:
1. All living organisms are composed of CELLS, which according to the cell theory as proposed in the 1800's is the smallest structural and functional unit of life.
2. REPRODUCTION is a characteristics possessed by all living things. It is the process whereby living organisms/things create new living things.
3. IRRITABILITY is another characteristics of living things, which is the process whereby living things respond to changes in their environment called STIMULUS e.g heat, nutrient stress e.t.c.
The diagram compares diffusion of sugar molecules and osmosis. Explain the difference between osmosis and diffusion in cells
Answer:
What is the difference between osmosis and diffusion? Osmosis is the movement of water molecules through the cell. Diffusion is the movement of molecules, such as oxygen, in and out of a cell. The process by which water molecules are able to diffuse through the cell membrane.
Explanation:
Diffusion and osmosis involves the movement of materials from one region another. The main difference between osmosis and diffusion is that osmosis requires a semi permeable membrane.
The movement of materials always occur in cells. This movement could occur by;
Active transportOsmosisdiffusionThe difference between osmosis and diffusion is that, diffusion does not involve a semi permeable membrane.
A semi permeable membrane is a membrane that is selectively permeable to materials. It allows some materials to pass and does not allow other materials to pass. We can see the semi permeable membrane as the structure in the osmosis diagram that separates the two regions.
Diffusion does not require the use of a semi permeable membrane.

A student is performing an investigation using rennin and milk. Rennin is an enzyme that can solidify milk. She
puts milk in three test tubes with rennin and places the tests tubes in water baths at different temperatures
of 32°F, 98°F, and 212°F. She notices the rennin enzymes become denatured at 212°F and do not solidify
the milk. Which statement correctly describes the effect of the denatured enzymes?
A. Denatured enzymes are slowly active.
B. Denatured enzymes are no longer active
C. Denatured enzymes reverse the reaction.
D. Denatured enzymes speed up the reaction.
Answer:
The correct answer is - option B. denatured enzymes are no longer active.
Explanation:
Denaturation of the enzymes or proteins results in changes in their original structure which ultimately results in the loss of their particular functions. The denaturation of proteins or enzymes takes place due to extreme temperature or pH which leads to a change in the active site of an enzyme.
Due to this change, the substrate will no longer fit in the active site and become inactive as enzymes work together with the substrate and the active site is the essential part of the enzyme for its activity. In this case, this is condition takes place which makes it denatured at 212 degrees F.
Which three statements make up the law of gravity?

Explanation:
If the DNA integrates properly into the germ cells, the adult fly will contain _________________ that contain _____________________________. After mating, these flies can then produce progeny that will contain ______________________.
Answer:
Five pairs of autosomal and one pair of heterochromatic sex chromosomes.
Explanation:
The adult fly will contain 12 number of chromosomes that contain five pairs of autosomal and one pair of heterochromatic sex chromosomes. After mating, these flies can then produce progeny that will contain diploid i. e. double number of chromosome. One set of half chromosomes from the male fly while the other half chromosomes comes from female fly so the offspring will receive double number of chromosomes.

Explain what factors can lead to genetic
variation within a population.
Answer:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).

If you used a slingshot to launch a bowling ball and a baseball with the same force, which would go further? Explain your reasoning.
Answer: The baseball will go farther because of Newton's law. The more mass an object as, the more force needed to move it. The bowling ball has more mass than a baseball so more force is needed to move it.
Explanation:
What is actually cycled in a web of organisms?
Answer:
Carbondioxide gas.
Explanation:
Carbondioxide gas is actually cycled in a web of organisms, The plants takes carbondioxide gas for the process of photosynthesis, this plant is eaten by herbivores for energy and carbondioxide is released in the process of respiration. After that, carnivores feed on these herbivores and oxygen is used in the breakdown of food for releasing energy and carbondioxide gas is also released from the body through breathing so the cycle of carbondioxide gas is continue.

A. Red blood cell: Blood cell that is a product of the medulla. These cells contain hemoglobin that carries oxygen from the lungs to the rest of the body.
B. Megakaryocyte: Big cell easy to recognize for its size. Differs from other cells for being polyploid, growing by endomitosis, and being bigger. They have important biological functions. The most important one is the formation of plaquettes, necessary for hemostasia, damaged vessels reparation, and tissue healing.
C. Eosinophil: Granulosites. Immune System cells, active during infections, pathologies, inflammations, and allergies. Originated in the medulla and transported to the blood and organs. One of their functions is to defend the organisms from parasite infections, helping to destroy the pathogen.
D. Basophil: Granulosites. Immune System cells. in the medulla and transported to the blood. Only when there are parasite infections they can be present in tissues and organs. They release substances such as histamine that make possible the inflammatory process.
E. Monocyte: Agranulocyte phagocyte. Originated in the medulla and transported to the rest of the body. They differentiate into macrophages in tissues. They defend the body from bacteria and viruses. When monocyte values are elevated, usually means that there is an important process of infection.
F. Neutrophil: Phagocytic Leucocytes polymorphonuclear found in the peripheric blood. Compose the first defense line against bacterial and fungal infections. Product of the medulla and transported to the blood. They are the first to arrive at the affected tissue, followed by lymphocytes and macrophages.
G. Lymphocyte: Leucocyte. There are two types of lymphocytes: B cells, which can produce antibodies in the presence of bacteria, viruses, and toxins. T cells can destroy infected cells from the body. They all circulate in the blood.
H. Formed elements: Elements that might be found suspended in the plasma. These include all the mentioned cells and cell fragments
I. Plasma: Transparent, acellular, and kind of yellow liquid that represents 55% of the blood volume.

Why would looking for the persons responsible for sneaking endangered species (rare birds, for example) into the United States be considered a job for a forensic scientist
Answer:
Forensic scientists are able to find the answer.
Explanation:
The persons responsible for sneaking endangered species into the United States be considered a job for a forensic scientist because forensic scientist is able to find out the persons. Forensic scientist are the investigators who collect evidences from the crime scene and leads to the person who commit crime. So the forensic scientist is the only person who find out the persons responsible for sneaking endangered species.
