Gene therapy has been used to treat and cure cystic fibrosis. Cystic fibrosis is caused by a _________ in a single gene?
Answer:
mutation
Explanation:
trust me, i took the test
Gene therapy has been used to treat and cure cystic fibrosis. Cystic fibrosis is caused by a mutation in a single gene.
What are mutations?A mutation is a change in the DNA sequence of an organism. Mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection.
Moreover, hereditary mutations include cystic fibrosis, hemophilia, and sickle cell disease. Other mutations can happen on their own during a person's life. These are called sporadic, spontaneous, or new mutations. They affect only some cells.
Therefore, mutations can result from errors in DNA replication during cell division, exposure to mutagens or a viral infection. Germline mutations (that occur in eggs and sperm) can be passed on to offspring, while somatic mutations (that occur in body cells) are not passed on.

What do you think happens to the particles of air inside the ball as it warms in the sun?
There is matter inside the balloon. The mixture of gas present in the balloon is a form of matter which has some kinetic energy which will increase with the increase in temperature.
What is Kinetic energy?Kinetic energy is the energy present inside a body which is in motion. Here, the molecules of gas present inside the balloon possess kinetic energy. The kinetic energy of all the gases is almost similar at a specific temperature regardless of their constituents.
The kinetic energy of gas present inside the balloon increases with the increase in the temperature. When the balloon is kept in the sun, due to the heat of Sun, kinetic energy of gas particles inside the balloon also increases and the balloon expands. This will lead to an increase in the pressure on the walls of the balloon.

What is the end result of meiosis? four identical daughter cells four different daughter cells two identical daughter cells two different daughter cells
Answer:
B. Four Different Daughter Cells
Explanation:
The end result of meiosis results in the production of four genetically different daughter cells.
The result of meiosis is four different daughter cells.
• A kind of cell division, which minimizes the number of chromosomes in the parent cell by half and generates four gamete cells is known as meiosis.
• This process is needed to generate sperm and egg cells for sexual reproduction.
• Meiosis starts with a parent cell, which is diploid, that is, it has two copies of each chromosome.
• The parent cell goes through one round of replication of DNA succeeded by two distinct cycles of nuclear division.
• In the end, four haploid daughter cells are produced, that is, they contain half the number of chromosomes present in the parent cell.
Thus, four different daughter cells are produced at the end of meiosis.

Organisms may contain up to five levels of organization within their bodies. Which level of organization is best represented by the liver?
tissue
organ
organism
organ system
Answer: The liver best represents an organ.
Explanation:
Liver is the largest organ in the human body. It does multiple functions in the physiological system. The correct option is organ.
What are the levels of organization?1. Cell - Cell is the fundamental unit of life. It is the smallest level of organization.
2. Tissue - tissue is a group of cells that are structurally and functionally similar, for eg. muscle tissue, connective tissue.
3. Organ - an organ is a group of tissues that function in a combined manner, for eg. liver, stomach.
4. Organ system - an organ system is a group of organs that function for a specific physiological purpose, for eg. nervous system, digestive system.
5. Organism - an organism is a whole individual which is made up of the various tissues and organ systems, for eg. human being, animals, plants.
A diagram is attached that illustrates these above mentioned levels of organization
Liver is made up of different types of tissues such as the hepatic laminae, bile canaliculi, hepatic sinusoids, hepatic and portal lobule and the hepatic acinus.
Thus, the correct option is organ.

Why do plants supplies bacteria with amino acids ?
Answer: All living cells need nitrogen to make nucleic acids, proteins, and other cellular constituents. Plants absorb nitrogen and put them into amino acids and proteins. Other organisms consume the plants. As part of the major nutrients in the diet, amino acids should be particularly taken into account since they not only support the growth and survival of bacteria in the GI tract [27], but also regulate energy and protein homeostasis in organisms [28,29].

Using the diagram above, in what direction will water flow?
into the cell
out of the cell
into and out of the cell at equal rates
Answer:
According to the diagram, where there is the highest concentration of solutes in the cytoplasm, the water will flow into the cell.
Explanation:
Taking into account a difference in solutes concentration between the extracellular and intracellular spaces, the movement of water will be from the space with the lowest concentration of solutes to the space with the highest concentration of solutes, which explains the osmosis.
In the diagram, as there is a higher concentration of solutes in the intracellular space —cytoplasm— the water will pass from the outside to the inside of the cell, due to the force generated by a concentration gradient. The movement of water will be maintained until equilibrium of solute concentrations is reached.
Molecurlar motion is a measure of the movement of the molecules in a substance for example the molecules in _______ move more than the molecules
