Answer:
The easiest one to correct would most likely be Class V, since in this type of mutation, the only problem or abnormality is the production of insufficient amounts of the needed CFTR.
Explanation:
Mutation Classes
Class I - Gene contains a stop signal that prevents CFTR from being made.
Class II - CFTR is made, but does not reach the cell membrane
Class III - CFTR is made and in the right place, but does not function normally
Class IV - Channel does not move substances efficiently or at all
Class V - CFTR is made in smaller than normal quantities
name and describe the process occurring in the nucleus which results in the formation of an mRNA molecule
Messenger ribonucleic acid (mRNA) is the single-stranded biological molecule that resembles the hereditary sequence of the gene and is needed for coding the proteins molecules essential for cell function and growth.
Transcription is the process that occurs in the nucleus.
What is the process that synthesizes the mRNA?mRNA is the biological molecule that gets formed from the double-stranded DNA molecule by the process of Transcription in the nucleus of the cell.The replicated DNA undergoes a transcription process and it's one strand transcripts to form a single strand of the mRNA molecule with the help of the transcription factors.One of the DNA strands acts as a template for the formation of the pre mRNA molecule with the help of the RNA polymerase II enzyme. The pre molecule formed undergoes an elongation and the termination process and the final mature mRNA is formed.Therefore, transcription results in the formation of the mRNA.

B-Secondary Consumer
C-Tertiary Consumer
D-Decomposer
Answer:
C-Tertiary Consumer
Explanation:
The diets of tertiary consumers may include animals from both the primary and secondary trophic levels. Like secondary consumers, their diet may also include some plants. Examples of tertiary consumers include Hawks, Alligators and Coyotes. Hawks feed on small mammals, lizards and snakes.
Phillip Gingrich finds an S-shaped bone in this partial skull, a sigmoid process, which is unique to
one particular order of animals in the water today... which one?
Answer:
A primitive whale which he named Pakicetus.
Explanation:
Philip Gingrich is a vertebrate paleontologist at the University of Michigan. He has performed extensive research on whales at the Egyptian desert of Wadi Hitan. His research team member discovered a skull whose braincase was bigger than that of a walnut. Gingerich was able to link the small-brained animal, to an early whale.
The auditory bulla had an s-shaped bony crest known as the sigmoid process and these two features helped whales to hear in water. The case, however lacked other features that helped whales hear beneath the waves. This led Gingrich to the conclusion that the unknown animal was semi-aquatic. This finding also lent credence to the possibility of whales evolving from terrestrial animals.
There are 10 pieces of candy in a bowl and 2 of them are chocolate. What percentage of the pieces of candy in the bowl are chocolate?
Answer:
20%
Explanation:
2 out of 10 is the same as 20 out of 100. So 2/10 = 2/100 or 20%
The two birds shown in Figure A and B are found on one island. The bird species in figure A is moved to a new island, where food size and shape are different from the food found in their current island. The birds left behind (Figure B) on the original island continue to grow and reproduce.
What changes might a scientist expect to see in the species?
A.
The birds on the old island would not change over time and evolve.
B.
The birds on the new island would evolve over time and die out.
C.
The birds on the old island would evolve over time and develop adaptations in their beaks to allow them to eat new types of food.
D.
The birds on the new island would evolve over time and develop adaptations in their beaks to allow them to eat new types of food.
Answer:
D.
Explanation:
because if the birds in figure A move to the new island with new food size and shape they will adapt to the food
how would you describe what the cells of each stage of the cycle look like ? what are the visible features of the cells.
Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis
Interphase:
Is known as the resting stage. Replication of DNA occurs.
- G1
-S
-G2
Prophase:
The chromosomes are visible, centrioles are formed and begin to move to opposite sides. This is where you see the dissolving of the nuclear membrane.
Metaphase:
The chromosomes line up in the centre of the cell.
Anaphase:
This when the cell divides (should look like two circles splitting) you will see the spindles begin to shorten which pull chromatids apart.
Telophase:
The nuclear membrane is reformed.

Answer: Edith Widder uses the bioluminescence (light) produced by the different sea creatures to identify their various species. For example, during her talk, she mentions a fish with a headlight behind its eye that retracted like a Lamborghini’s headlight. She also describes a Christmas tree fish where everything lights up, including the jewel-like organs in its body.
Explanation: This question comes from the TED talk "Glowing life in an underwater world" by Edith Widder. During her talk, she vividly describes her experience seeing sea organisms that display bioluminescence in the ocean.

A cell that is placed in distilled (plain) water will swell up because it fills
with water. Which process causes the cell to swell?
Answer:
If a cell is placed in a hypotonic solution, water will move into the cell. This causes the cell to swell, and it may even burst. A hypertonic solution means the environment outside of the cell has more dissolved material than inside of the cell. If a cell is placed in a hypertonic solution, water will leave the cell.
