Explanation:
Suppose that a cytoplasmic protein (a protein that will function in the cytoplasm inside of the cell) is synthesized by a particular cell type. Describe the route that this protein will take from the moment its synthesis starts in the nucleus until it makes it into the cytoplasm.
Answer:
A specific gene that contains the information to encode the target protein is transcribed as a primary transcript (pre-mRNA). Subsequently, the pre-mRNA is processed to form a mature mRNA. Finally, this mRNA then moves through a nuclear pore from the nucleus to the cytoplasm where proteins are translated in the ribosomes
Explanation:
The cell nucleus contains the majority of the cell's genetic material localized on linear molecules called chromosomes. During transcription, genes (specific chromosome segments) are used to synthesize primary transcripts (pre-mRNAs) which are then proceeded to produce mature messenger RNAs (mRNAs). RNA processing involves the removal of non-coding intron regions and the joining of coding exon regions (RNA splicing) in order to form a mature mRNA sequence. Subsequently, the mature mRNA leaves the nucleus through the nuclear pores of the nuclear membrane and travels to the ribosomes where is decoded (translated) to produce a specific polypeptide chain (i.e., a protein). Within the ribosome, the mRNA strand binds to multiple transfer ribonucleic acids (tRNAs) via complementary and consecutive three-nucleotide mRNA sequences called triplets or codons, and tRNAs deliver specific amino acids that are consecutively added to the polypeptide chain.

Answer:
Adenine (A) = 28%
Cytosine (C) = 22%
Explanation:
The DNA molecule, which is the genetic material that stores or holds information needed by the cell for growth, reproduction etc. Structurally, the DNA is composed of nucleotide subunits, which are of four types namely; Adenine, Guanine, Cytosine, and Thymine etc.
According to Chargaff in his complementary base pairing rule, he states that Adenine will always pair with Thymine (A-T) while Guanine will always pair with Cytosine (G-C). Based on this, Chargaff further stated that the amount of adenine must be equal with that of thymine while that of guanine must be equal to cytosine.
In total, their total amount must be equal to 1 or 100% i.e. (A + T) + (G + C) = 100%. In this question, 22% of Guanine are found in the DNA of a fox. This means that automatically, the percentage of cytosine is 22%. We then calculate the amount of Adenine and Thymine as follows:
(A + T) + (G + C) = 100%
A + T + 22 + 22 = 100
A + T + 44 = 100
A + T = 100 - 44
A + T = 56
Since A = T,
56/2 = 28
Hence, A = 28%, T = 28%
Which of the following are internal cellular conditions?
A) temperature, pH, water concentration, salt concentration
B) sunlight, dry environment, wind
Answer: a
Explanation:
The following are internal cellular conditions :
A) temperature, pH, water concentration, salt concentration.
Temperature facilitates deciding what can input or depart the cellular and the way properly molecules observed inside the membrane can function. Temperatures that might be too excessive or too low can severely harm and, in the intense temperature ranges, kill the cellular via their impact at the cellular membrane.
Physiologically ordinary intracellular pH is maximum generally among 7.0 and 7.4, even though there may be variability among tissues (e.g., mammalian skeletal muscle has a tendency to have a pHi of 6.8–7.1). There is likewise a pH version throughout special organelles, that can span from round 4.5to 8.0.
Water concentration:
Water molecules flow into and out of the cell at an identical fee, so the length stays constant. then a cell. This method of water attention is better within the cell than outside. Thus, water flows out of them, inflicting them to shrivel or maybe die.
Salt concentration:
Increase of the way of life medium NaCl attention from a hundred and 20 mm to 220 mm ended in a reduced boom fee and a boom in the content material of ribonucleic acid (RNA), protein, and lipide phosphate consistent. Cell quantity becomes likewise increased.
How to maintain internal cellular conditions?An organism ought to be capable of keeping internal cellular conditions even if the outside surroundings modify. Examples of modifications encompass pH, temperature, salt levels, water levels, and glucose levels.

A. Inventing tools can help humans survive in their environment.
B. Overusing resources can make a survival practice unsustainable.
O .
C. Developing different religions can lead to conflict among
societies.
D. Having opposable thumbs helps humans grasp objects.
Answer : A
Explanation:
Inventing tools can help humans survive in their environment. Therefore, option (A) is correct.
Why inventing tools help human survive?Culture refers to the shared beliefs, values, practices, and knowledge that characterize a group or society. Humans have relied on culture to survive and thrive for thousands of years. Inventing tools is an example of how culture can help humans survive. By creating and using tools, humans are able to adapt to and manipulate their environment to meet their needs. For example, early humans used tools to hunt, gather food, and build shelters, which helped them survive in their environment.
Overusing resources can lead to unsustainability and environmental degradation, which can threaten human survival. Developing different religions can lead to conflict among societies and does not necessarily help humans survive. Having opposable thumbs is a physical adaptation that has helped humans develop complex motor skills, but it is not an example of how culture helps humans survive.

Some scientists are modifying the genetic code of certain fish by inserting genes that cause the fish to produce more growth hormone, which causes the fish to grow more quickly. Salmon is one type of fish on which scientists are working. Which answer choice shows the most significant negative impact to society that could result from producing genetically modified salmon?
Salmon cells could become less responsive to the hormone over time, slowing the growth rate of the fish.
Salmon could be reintroduced into the ecosystem where they could breed with, and alter, populations of wild salmon.
The genetically modified salmon will be very expensive to raise, so the fish will be too expensive for people to buy.
The modified, farmed fish would be more difficult for predators to hunt than wild salmon if reintroduced into the ecosystem.
Answer:
breeding with and altering the population of wild salmon
the extra growth hormone could change the wild salmons reproductive fitness, could slow them down or make them less fertile or more fragile so they aren't able to spawn etc and reduce the wild population of salmon which would have large effects
