A nonsense mutation is one mutation in the CFTR gene that leads to cystic fibrosis causes translation to end earlier in the gene sequence.
Cystic fibrosis is a genetic disorder that is caused by different mutations within the CFTR gene.
The CFTR gene codes for the CFTR protein whose function is as an anion channel (chloride ion) which helps control the movement of water in and out of the membrane of cells that are specialized to produce mucus, sweat, saliva, tears and digestive enzymes
When CFTR protein is defective or absent, thick, sticky mucus accumulates in these cells, obstructing the airways and glands.
The most common mutation of the CFTR gene is a deletion whereby the codon for the amino avid phenylalanine is deleted resulting in the production of a defective CFTR protein.
Another form of mutation in the CFTR gene is a nonsense mutation in which a stop codon is inserted in the middle of the gene resulting in the production of a shortened CFTR protein, which is then degraded by the cell.
Therefore, a nonsense mutation in the CFTR gene leads to cystic fibrosis by causing translation to end earlier in the gene sequence.

What are ice cores and how are they useful in giving us info about the past?
Answer:
Ice cores are cylinders of ice drilled from ice sheets/glaciers. ice cores tell scientists about temperature, volcanic activity, atmospheric composition, precipitation, and wind patterns.
Explanation:
the thickness of each layer in the core allow scientists to determine how much snow fell in the area during a particular year. the layers are formed by layers of different types of snow. During the summer, when it is light for 24 hours, the snow on the top layer changes texture. When winter arrives, it turns dark and cold again and more snow falls on top of the summer snow, creating distinct layers.

How are the phases of Venus different than the phase of our moon?
Answer:
Venus is an inferior planet. Because Venus is so close to the Earth and lies nearer to the Sun, it shows phases, similar to the way the Moon does. It also is closer to us near inferior conjunction (bigger) than at superior conjunction (smaller), and so its angular size changes as the distance between us varies.

Seed that had been planted 10cm deep won't get enough sunlight and adding water to make it grow just makes the condition even worse.
Seed that had been planted 5cm deep might not get sufficient sunlight because the rays of the sun cannot pass through the soil.
Seed that is on the top of the soil might get carried away by the wind, or dried due to extreme sunlight, or might get carried away by a predator.

Which statement correctly describes how an organelle contributes to the ability of the cell to perform life functions?
The lysosomes digest food and break down cell parts when they die and the cell membrane prevents all harmful substances from entering the cell. So, the correct options are C and D.
What is Cell?Cell is defined as the smallest unit that can live on its own and that makes up all living organisms and body tissues where the cell has three main parts: cell membrane, nucleus, and cytoplasm. The cell membrane surrounds the cell and controls the movement of substances into and out of the cell.
A single cell is itself an organism. For example, yeast or bacteria. Other cells acquire specialized functions soon after they mature which acquire unique functions when they mature. They cooperate with other cells and become the building blocks of multicellular organisms such as humans and animals.
Therefore, the correct options are C and D.

1. Which of these particles is the smallest? (SC.8.P.8.7) *
A. an atom
B. a nucleus
C. a proton
O D. an electron
Answer:
The smallest particle is the electron (option D).
Explanation:
The electron is a subatomic particle, which is part of an atom and has a negative electrical charge.
Electron is a small particle, if compared to protons -electrically positive particles- whose size is about 1800 times bigger. In fact, the electron is the smallest particle inside the atom.
According to this, the other options, atom, nucleus and proton are structures larger than an electron.
Rabbits normally eat some grass as a food source. In a habitat, a new species of grass is introduced that out-competes most of the original species of grass. The new species of grass contains a chemical that is usually toxic and fatal to most rabbits. Assuming that all rabbits in this habitat will eat some of the new species of grass, how will the presence of the new grass most likely decrease the diversity of the rabbit population in this habitat?
Answer:
Well The Diversity will decrease.
Explanation:
If the Grass Is Toxic to the Rabbit than the rabbits will either die from eating the grass, or they will stop eating it and need to find a new food source. this will lead to the to the rabbits that are resistant to the toxic grass being able to reproduce more and therefor becoming more abundant.

property common to alkali metals: they react with water. How does the reactivity vary
among this group of elements? Why might patterns like this be useful to scientists?

produced by one of their offspring.
Which of these best describes this inheritance pattern?
х
O codominance because he fruit color of the offspring is
an intermediate form of the parents' fruit color
O codominance because both parents' colors are
expressed in the offspring
O incomplete dominance because both parents' colors
are both visible in the offspring
O incomplete dominance because the fruit color of the
offspring is an intermediate form of the parents' fruit
color
Answer:
incomplete dominance because the fruit color of the offspring is an intermediate form of the parents' fruit color
Sry if I'm wrong, have a nice day.
The given image shows incomplete dominance because the fruit color of the offspring is an intermediate form of the parents' fruit color. The correct option is D.
What is incomplete dominance?When both alleles of a gene are only partially expressed at a locus, it is known as incomplete dominance.
This sort of gene interaction frequently produces an intermediate or distinct phenotype. Additionally called partial dominance.
Two other types of genetic inheritance are codominance and incomplete dominance. It basically means that no allele can prevent or stifle the production of the other allele through codominance.
Incomplete dominance, on the other hand, occurs when a dominant gene does not entirely block the effects of a recessive allele.
Fruit produced by two parents and fruit produced by one of their children are shown in the photo.
Because the fruit color of the offspring is an intermediate version of the fruit color of the parents, it is incomplete dominance.
Thus, the correct option is D.

PLEASE HELPPPPPPPPPP!!!!!!! Explain how ATP and ADP act as allosteric regulators of enzymes that are responsible for ATP production, and how that is an example of feedback inhibition.
Answer:
The molecules that bind cellular respiration enzymes act as signals, giving the enzyme information about the cell's energy state. ATP and ADP are examples of molecules that regulate cellular respiration enzymes. ATP, for instance, is a "stop" signal: high levels mean that the cell has enough ATP and does not need to make more through cellular respiration.
This is a case of feedback inhibition in which a product feeds back to shut down its pathways.
Answer:
Specific enzymes of the electron transport chain are unaffected by feedback inhibition, but the rate of electron transport through the pathway is affected by the levels of ADP and ATP. Greater ATP consumption by a cell is indicated by a buildup of ADP. As ATP usage decreases, the concentration of ADP decreases: ATP begins to build up in the cell.
